Dr. Youngsang Cho, who has dedicated the past 35 years to organic farming, has completed a comprehensive 638-pages book citing over 900 references to thoroughly establish the scientific foundation of the “Ultra-Low-Cost Farming” technology he has championed. This work was crafted with immense dedication to provide highly practical and beneficial information for organic farmers in the field. 

Previous JADAM Organic Farming manuals were translated into 16 languages and received international acclaim from farmers worldwide, but they faced two major barriers. To maximize pest control efficacy, farmers were required to use soft water and rely on ginkgo berries, which can be difficult to obtain depending on the region. After 3years of intense research to overcome these limitations, the ultimate innovation, JADAM Microbial Pesticide (JMP), was finally created. 

Inspired by the European Union’s microbial pesticide policy, proposed as an alternative to achieve a 50% reduction in chemical pesticides, this JMP technology originated from the counterintuitive idea of utilizing various toxins found in indigenous microorganisms within leaf mold and surrounding soil. Consequently, JMP was developed to exert powerful insecticidal and fungicidal effects comparable to chemical pesticides, completely without the need for soft water or ginkgo berries. It excellently controls notoriously difficult pests such as thrips, snails, and scale insects, as well as household pests like mosquitoes and cockroaches. 

More surprisingly, despite its potent pest control capabilities, JMP is ecologically safe enough to be harmless to honey bees. This technology, which has undergone cross-verification by countless farming households, does not cause pest resistance unlike chemical pesticides. Furthermore, it rapidly decomposes in the soil, turning into nutrients that actually enrich the earth. It serves as a perfect alternative for coexisting with nature and restoring a planet ailing from chemical substances. 

JADAM intends to return the power of agricultural technology, once monopolized by massive capital, back to the farmers. To prevent corporate commercial monopoly, PCT patents have been filed in 157 countries worldwide, while the technology has been entirely disclosed so that anyone can easily create and use it free of charge. The past 35 years have been a journey of enduring various hardships, and financial crises, driven solely by the conviction that “ farmers must be the masters of technology.” 

JADAM will continuously strive to uphold its values for farmers and Mother Nature without weavering. We hope to share the immense promise of the new agricultural era ushered in by JMP with everyone.

FAQ: Quick Fact
 Q: What are the key additions to the newly revised edition of the JADAM Organic Farming book, and how extensive is it? 
A: To thoroughly establish the scientific background of ultra-low-cost organic farming, the book includes over 900 references. Spanning 638 pages, it notably introduces the innovative JADAM Microbial Pesticide (JMP) technology, which delivers powerful pest control effects without the need for soft water or ginkgo berries. 
 

Dr. Youngsang Cho, the pioneering leader of the Ultra-Low-Cost Organic Farming movement, received his Ph.D. in Agricultural Biology on August 22, 2025, from the Department of Agricultural Biology at Jeonbuk National University in South Korea. This achievement is regarded not merely as an individual academic milestone but as a historic event demonstrating that the JADAM movement, which has provided alternatives for farmers for decades, has now been academically recognized.

Dr. Cho stated, “The future of agriculture opens when farmers themselves realize Ultra-Low-Cost farming through self-manufacture of inputs.” Throughout his life, he has dedicated himself to developing organic farming technologies that anyone can practice at low cost, free from dependence on chemical pesticides. Reflecting on his doctoral degree, he said, “Now it has been proven that JADAM is not just a farmers’ movement but a scientific model to be shared globally.”

Although organic farming has been spotlighted as a healthy and sustainable alternative, it has been difficult for farmers to adopt in practice, mainly due to the lack of effective measures to control pests and diseases. Existing organic inputs have often been either ineffective or too costly, making it nearly impossible to replace chemical pesticides in large-scale agriculture.

JADAM has directly overcome these challenges. The natural pesticides developed by Dr. Cho comply with the U.S. Environmental Protection Agency’s (EPA) organic farming standards. They deliver insecticidal and fungicidal efficacy on par with chemical pesticides, yet can be produced directly by farmers at Ultra-Low-Cost. By identifying materials that can be sourced globally and systematizing them, Dr. Cho created an innovative, eco-friendly pesticide that any farmer can easily manufacture and apply.

These JADAM natural pesticides achieve what traditional organic inputs could not - the effectiveness of chemical pesticides - while remaining affordable and transparent. All formulations are openly published, enabling anyone to learn and apply them. The cost is only a fraction of that of commercial pesticides, drastically reducing farmers’ economic burden. This breakthrough has shattered the long-held perception that organic farming is “unrealistic,” opening the way for farmers to continue agriculture sustainably without chemical dependence.

Dr. Cho’s doctoral dissertation focused on the development and application of JADAM Microbial Pesticide (JMP) and other JADAM natural pesticides. Importantly, it was not limited to laboratory research but included validation of their effectiveness in real agricultural settings. The study demonstrated that microbial-based JADAM pesticides provide insecticidal and fungicidal efficacy comparable to chemical pesticides. It also confirmed that by utilizing eco-friendly surfactants such as decyl glucoside, JADAM formulations achieve practical levels of penetration and systemic activity, making them highly usable for farmers. Furthermore, the study academically organized how self-manufacture reduces farming costs and restores farmer autonomy.

This dissertation officially confirms that the JADAM method, already experienced firsthand by countless farmers, is also a scientifically validated model. JADAM is now firmly established not merely as an alternative but as a new standard for agricultural innovation.

Today, JADAM has more than 200,000 members worldwide. Dr. Cho’s book, JADAM Organic Farming, has been translated into 20 languages and is used as a guidebook by farmers across the globe. JADAM provides free Q&A support through its official website, personally overseen by Dr. Cho. The organization also actively engages with farmers through YouTube and Instagram, while in Korea, more than 700 donors participate in an open chat group (a group messaging platform widely used in Korea) for real-time, field-based discussions. This demonstrates that JADAM has grown beyond a simple technology-sharing initiative into an international farmers’ network.

The contamination of soil, crops, and food caused by chemical pesticides has become a pressing global issue. JADAM offers a practical alternative: Ultra-Low-Cost organic farming technology that anyone can make and use. Through this, countless farmers are reducing production costs, producing safe food, and protecting the global environment.

Dr. Cho’s doctoral achievement is not merely personal honor. It symbolizes the academic validation of the JADAM method, which has been tested and refined in collaboration with farmers in the field. What began as grassroots practice has now been systematized into technology accessible to all and scientifically recognized through this Ph.D. This represents a symbolic milestone proving that the JADAM philosophy - that farmers themselves must be the owners of agricultural technology - has become a strong bridge connecting practice and academia.

 Before announcing this overwhelming new technology, I would like to explain the process leading up to the development of this innovative JADAM Microbial Pesticide (JMP) (If the long text feels tedious, please refer to the summary of the JMP at the end).

For decades, I have dedicated myself to researching and perfecting a self-manufacturing method for organic pesticides, which I believe is the most critical element in completing Ultra-Low-Cost organic farming. The goal of my research was to create an organic pesticide that drastically reduces the cost of conventional pesticides by more than 1/20, can be easily self-manufactured at the farm level, and delivers powerful effects capable of completely replacing chemical pesticides.

Based on my experience, as long as commercial seeds are used, organic farming also requires thorough pest control with organic pesticides (hereinafter referred to as pesticides). However, commercially available eco-friendly pesticides place a significant economic burden on farmers. For the widespread adoption of organic farming, ultra-low-cost self-manufacturing is absolutely necessary. The illusion of leisurely farming without pesticide spraying is impossible with improved seeds in organic agriculture.
 

As the first result of my research, I developed a groundbreaking technology to solubilize sulfur, which typically melts at 120°C, without heating, and named it JADAM Sulfur (JS). JS can be self-manufactured with very simple equipment and can even control anthracnose, making it popular not only among organic farmers but also among conventional farmers. Unlike general sulfur products, JS causes almost no damage to vinyl or metal pipes.

As the second result of my research, I succeeded in drastically simplifying the manufacturing technology for liquid soap using natural oils, which previously required differential heating, long stirring times, and long aging periods. I reduced the process to no heating, 10 minutes of stirring, and 3 days of aging, completing it in just 4 days, and named it JADAM Wetting Agent (JWA). JWA can also be self-manufactured with very simple equipment and functions as both a wetting agent and an insecticide.

When JS and JWA are mixed, they become a fungicide so powerful that it cannot be compared to chemical pesticides. All materials used in this mixture are classified as safe substances under the U.S. Environmental Protection Agency (EPA) categories 4A and 4B, which are permitted for organic farming worldwide.

The third result of my research was the discovery of a plant capable of controlling almost all pests, including mosquitoes. I verified the effectiveness of this plant by applying it to over 60 different crops for five years and observing the pest control results. I revealed that the plant is ginkgo berry and named the pesticide made by combining JADAM Herbal Solution (JHS) with a ginkgo berry water with JWA as a ‘Broad-Spectrum Universal Insecticide.’

When JS, JWA, and JHS with ginkgo berry, they become a ‘Universal Fungicide-Insecticide,’ with pest control effects as powerful as chemical pesticides. This mixture also serves as a nutrient for plants, and notably, it does not lead to resistance even with repeated use. Additionally, it causes almost no harm to bees and butterflies.

In addition, I have developed control methods for the most challenging pests, such as thrips, scale insects, snails, and the Coffee Berry Borer (CBB), and made them publicly available to all farmers worldwide through the JADAM website (en.jadam.kr) and YouTube channel. JADAM has consistently refused to let corporations monopolize agricultural technology for commercial gain and has devoted itself to ensuring that farmers take the lead in agricultural technology.

As the fourth result of my research, I developed a technology that allows farmers to self-cultivate the microorganisms necessary for short-term soil improvement without relying on corporations. This cultivation method uses leaf mold soil from nearby areas as the microbial starter and boiled potatoes and sea salt as the medium—a very simple cultivation method. I named it the JADAM Microorganism Solution (JMS). The simplicity of the cultivation method makes it easy for farmers to follow, and its excellent soil improvement effects have made it highly popular among farmers.

The book containing the technologies I invented and developed has been translated into 16 languages, has received widespread support from people worldwide, and has been recognized as a bestseller on Amazon in the U.S. However, my technology has a clear limitation that prevents it from being widely adopted globally. The existing JADAM technology requires soft water for pesticide use, and ginkgo berries are essential for broad-spectrum pest control. Therefore, in regions where soft water and ginkgo berries are unavailable, JADAM technology becomes useless. Even in areas where ginkgo berries are available, many find the process of boiling them cumbersome.
 

I have felt frustrated by these limitations of JADAM technology, but I have worked hard to overcome them through long-term contemplation and research. As a result, I succeeded in developing a groundbreaking organic pesticide manufacturing technology that does not require soft water or ginkgo berries. Through 2 years of research, I confirmed its outstanding effects by testing it on over 70 different crops. Last August, I shared the technology with over 600 farmers in a JADAM SNS group (JADAM donator chat room) to cross-verify its effectiveness. This new technology delivers powerful broad-spectrum insecticidal and fungicidal effects, capable of almost perfectly controlling nearly all moths, snails, thrips, invasive pests, and even mosquitoes. Of course, if soft water is available, adding JWA can further enhance the fungicidal and insecticidal effects. I named this new technology the JADAM Microbial Pesticide (JMP).
 

Microbial pesticides are a field where global agrochemical giants are investing heavily in research, and several products are already on the market. Microbial pesticides are considered an organic alternative due to their minimal residual toxicity. However, most corporate research focuses on selecting specific microorganisms and using their toxins to control specific pests. As a result, commercially available microbial pesticides have a narrow control range, short shelf life, high cost, weak fungicidal effects, and are primarily effective only at the larval stage. Thus, they are expected to reduce the use of chemical pesticides rather than fully replace them.

After reviewing numerous papers on microbial pesticides, I concluded that an individual could not approach the research methods of corporations. Therefore, I set the direction of my microbial pesticide research to focus on methods where farmers could easily obtain microbial starters, self-manufacture them, achieve broad-spectrum insecticidal and fungicidal effects, and enable long-term storage. Initially, I felt lost, but I persisted in my research and sought solutions. While corporations focus on selecting specific strains and utilizing specific toxins, I aimed to overcome the limitations of existing commercial microbial products by using mixed strains (leaf mold) and mixed toxins. Even I thought this imagination was too far-fetched, and I had little expectation of success.
 

I had no choice but to select leaf mold soil as the microbial starter, as JADAM has always done, and I cultivated the microorganisms using my developed method with potatoes and salt. I conducted experiments expecting that mixing JWA as a wetting agent with the microbial culture would create a microbial pesticide, but the effects were negligible. Using JWA as a premise meant the microbial culture had to be made with soft water, and even then, mixing JWA with JADAM Microorganisms Solution (JMS) caused the JWA to degrade quickly, losing its spreading ability in a short time.

I needed a new surfactant to replace JWA—one that could be used in hard water, was permitted for organic farming, and was easily accessible worldwide. After testing dozens of surfactants, I finally selected Decyl Glucoside (hereinafter referred to as Decyl). This substance is classified under the EPA’s safest category for organic farming, 4B. It is a 100% naturally derived substance and, when maintained above a certain concentration, is not degraded by JMS over the long term. It is also non-ionic and can be used in hard water. Through various experiments, I determined the appropriate usage amount that does not cause phytotoxicity or concentration damage to crops, which is a 500-fold dilution.

I continued conducting pesticide experiments by mixing Decyl with JMS. While the pest control effects were certainly higher than when using JWA, they were not at a level worthy of public disclosure. My research hit a wall with no further progress. Then, it suddenly occurred to me to increase the amount of potatoes, the culture medium. I added Decyl to JMS cultivated more vigorously (with bubbles completely covering the surface of the culture tank) by increasing the potato quantity and tested it on pests. To my amazement, I witnessed insecticidal effects I had never experienced before. The pest control effects were so remarkable that I was utterly shocked.
 

I successfully tested the mixture of microorganisms and Decyl on nearly all pests affecting over 70 crops at the JADAM organic farm. The results are posted on JADAM YouTube and Instagram. Even more astonishing was that mosquitoes were completely eliminated, and it was highly effective against slugs and snails. Despite extensive global research on mosquitoes, little success has been achieved, but the JMS and Decyl mixture produced overwhelming results. My wild imagination of using mixed strains and mixed toxins ultimately led to incredible outcomes.

The JADAM Microbial Pesticide (JMP) is not a live microbial agent. It is a liquid formulation in which various microbial toxins are extracted by dissolving the microorganisms with Decyl. While spraying only JMS has no effect, the moment Decyl is mixed in, it instantly becomes an insecticide. Even more surprising is that the insecticidal effect of this mixture lasts for a year. The effect persists even if the mixture freezes and thaws repeatedly. It is best to store this mixture in a sealed, shaded condition. For those managing small fields, a new world has opened where organic farming can be easily achieved by producing microbial pesticides just 1 2 times a year.

While the JMS and Decyl mixture is effective against nearly all pests, its control effect on thrips and stinkbugs was somewhat lacking, so I continued research to perfectly address thrips control. I mixed JS with the JMS and Decyl mixture. However, the moment JS was added, the water became cloudy and sediment formed. I identified this as a phenomenon caused by the significant pH difference between the substances and conducted experiments using Potassium Hydroxide (KOH, 90%). I confirmed that the appropriate usage amount is a 1,000-fold dilution. By dissolving KOH to raise the pH to around 10 and mixing in JS, the mixture became clear and transparent. Though I explain it calmly now, I was deeply worried about whether JS could be used.
 

I tested the pesticide made by mixing JMS with Decyl, KOH, and JS on nearly all the most challenging pests, including thrips, stinkbugs, flea beetles, Daikon leaf beetle, Citrus Flatid Planthopper, Spotted Lanternfly, as well as diseases like powdery mildew, downy mildew, and anthracnose. The results were highly satisfactory. Thrips and stinkbugs gradually disappeared, reaching near-zero levels where they could hardly be found. It was an astonishing result that seemed impossible.

However, I was concerned about potential side effects from the powerful effects of the JADAM Microbial Pesticide (JMP). I continuously monitored three issues: first, whether it kills bees and butterflies; second, whether it hardens the soil; and third, whether it alters soil pH. Bees and butterflies were almost unaffected, the soil became even softer, and the soil pH stabilized within 7. I could not detect any effects of microbial toxins on the human body. Common symptoms of pesticide toxicity in humans, such as nausea, headaches, tremors, coughing, or rashes, were absent.

JMP causes almost no harm to bees, butterflies, and frogs. This is truly remarkable.
 

As the price of potatoes surged, utilizing them as a microbial culture medium became increasingly burdensome. To overcome this economic challenge, various experiments were conducted using inexpensive potato starch as a substitute. Although there were initial concerns that the nutrirional simplicity of potato starch might be unfavorable for culturing a wide variety of microorganisms or potentially microbial cultures remained highly effective as pesticides. Specifically, potato starch significantly delays the evaporation of pesticides compared to whole potatoes, thereby increasing both sterilization and insecticial efficacy. Concerns regarding acidification proved to be unnecessary. Additionally, a recently developed techique has been introduced that allows potato starch to be converted into a functional microbial culture medium in only 1 minute.

A single individual, through short-term research, overcame all the shortcomings of microbial pesticides developed by giant corporations and achieved remarkable broad-spectrum insecticidal effects. My invention of the JADAM Microbial Pesticide (JMP) will cause a seismic shift in the existing pesticide market, and I believe this could put JADAM at serious risk due to opposition from agrochemical companies. JADAM has already faced several dramatic crises in the past.

For faster dissemination, I have decided to distribute the latest 10GB of PPT materials used in lectures on USB drives to all JADAM Korea donators(Overseas donors are planned for the future). I hope that thousands or tens of thousands of instructors teaching the JMP will emerge, enabling rapid global dissemination. I am currently working on publishing a fully revised edition containing the new microbial pesticide by the end of the year. I also plan to produce and release related videos.

JADAM has been deeply committed to the principle that ‘farmers must take the lead in agricultural technology.’ The monopolistic control of agricultural technology by commercial capital is intensifying, and the economic independence of farmers is being severely undermined. I have spent decades seeking alternatives to bypass this desperate trend. The invention of the JMP will be a milestone in the global popularization of organic farming and the development of competitive organic agriculture. Before publishing the revised edition, I am releasing the new JADAM Microbial Pesticide (JMP) self-manufacturing method in advance. Spread the word! Spread the word!

■ Making a Powerful Insecticide, JADAM Microbial Pesticide (JMP)
(For 500 liters. A 600-liter culture tank is suitable)

JMP can control most pests except thrips and stinkbugs. It eliminates mosquitoes.

① Fill a clean, lightproof cultivation container that is free from contamination by this substance with 500 liters of water (hard water is acceptable). Tools, containers, and gloves used for microbial cultivation must be dedicated exclusively to this purpose. Containers previously exposed to pesticides, sulfur, or decyl glucoside must never be reused (critical). Highly contaminated groundwater can inhibit microbial growth. In such cases, the water should either be aerated using an air pump for approximately 24 hours, replaced entirely, or tap water should be stored for two days before use, as aeration is exceptionally effective at reducing water contamination.

② Pre-heat the water by setting a 3 kW portable immersion heater to 31°C. Since temperature discrepancies can occur with the heater, verify and adjust the temperature settings using an independent thermometer.

③ Boil 500 grams of potato starch in water and transfer it directly into the cultivator immediately without cooling. The following details the method for preparing potato starch as a culture medium. (Note: Increasing the quantity of potato starch can counterproductively diminish the control efficacy of the microbial pesticide. Furthermore, adding molasses, liquid fertilizer, or urine to accelerate growth may increase foaming during cultivation, but it severely impairs the production of microbial toxins, thereby reducing insecticidal efficacy.)

■ Making a Microbial Medium with Potato Starch (Potato starch is most effective)

- Pour 15L of water into a stainless steel or aluminum container (25L) and heat until it reaches a rolling boil.

- Dissolve 500g of potato starch in 2L of water, pour it all at once into the boilling water, stir for about 20 seconds with a wooden spatula, and then turn off the heat. 

- Add the completed starch liquid to the incubator water and stir with a large rod.

④ Place 500 g of high-quality leaf mold and 500 g of sea salt in a 120-mesh net, shake side to side in the culture tank water to dissolve, and hang the net in the tank (hanging it enhances microbial culture). Using separate mesh nets prevents nozzle clogging during pesticide spraying.

⑤ Slightly cover the culture tank with a lid to block sunlight. Ultraviolet rays from sunlight affect microbial culture.

⑥ After about 20 hours, the culture reaches its peak level. The culture is complete. It is finished when the microbial culture foam completely covers the surface of the water in the tank. If the foam is weak, culture for an additional 3 4 hours. Weak foam reduces insecticidal effects. If time permits, ambient temperature culture is also possible.

⑦ Transfer the JMS to a separate container using a submersible motor (mandatory), add 1 liter of Decyl Glucoside (permitted for organic farming), and mix. A JMP is easily completed. It can be used immediately after mixing. You must never mix Decyl Glucoside directly into a microbial incubator. This is because microorganisms cannot be cultured in a container mixed with Decyl Glucoside. When using a submersible motor, remove it from the culture tank while it is running to prevent backflow. If you don't have a submersible pump, transfer it with a bucket.

⑧ This JMP retains its effectiveness for 1 year when stored in a sealed, translucent container. It remains effective even after repeated freezing and thawing.
JMP is used as a stock solution without dilution.

■ Making a Powerful Insecticide and Fungicide, JADAM Microbial Pesticide (JMP.S)
(For 500 liters)

JMP can control nearly all pests, including thrips and stinkbugs, as well as various fungal diseases. It eliminates thrips.

① Add potassium hydroxide dissolved in water (dissolve 500 g of potassium hydroxide (90%) in 500 ml of water) to the mixture in step ⑦ above and stir with a long stick. Be careful of gas inhalation during the process of dissolving calcium hydroxide. Aluminum containers cannot be used. If potassium hydroxide is not pre-dissolved and added, JS will not be mixed transparently.

② Add 1.5 liters of JS and stir to complete. Use as a stock solution. For crops sensitive to sulfur, conduct a concentration damage test beforehand.

③ This JMP.S is effective depending on the degree of air exposure (the effect lasts for about 5 days). If the air contact is prolonged, the color of the mixture loses its yellow color and becomes white and translucent, and precipitation occurs. If it is completely sealed and stored in a shaded condition, the shelf life can be extended to 3 months..

④ When the JMS is made with soft water, 5 10 liters of JWA can be mixed to further enhance insecticidal and fungicidal effects. JMP is used as a stock solution without dilution.

FAQ: Quick Fact

Q: What is the principle behind JADAM Microbial Pesticide (JMP) technology, which enables the complete control of challenging pests like thrips, stinkbugs, and even mosquitoes without chemincal pesticide?

A: When microorganisms cultured from leaf mold soil are dissolved using Decyl Glucoside, microbial toxins are relseaed to complete a broad-spectrum insecticide. Adding JADAM Sulfur (JS) to this mixture results in a microbial pesticide that possesses both powerful germicidal and insecticidal properties, and JMP does not lead to the developemnt of pesticide resistance (Cho, 2026).

 A thrips is a small insect with a body size of 0.5 to 10 mm. It mainly lays eggs in petals or leaf tissue, and eats pollen, leaf flesh, and juice to damage crops. The period of adult stage is about 30-45 days, but since 150-300 eggs are laid during that time, if control is not successful at that time, it can cause great damage to crops.
 

Although thrips are considered to be difficult to control, even with chemical pesticides, JADAM has found a method with a high control effect after research. Unlike other bugs, thrips need to be observed for 3 hours after spraying the pesticide. As time passes, few of thrips might start to move again.  However, it is confirmed that the JADAM natural pesicide which is mixed with JWA, NaOH, red clay and JS can maintain the control effect even 4 hours passed after applied (You can see the video).

 When making JS, if Phyllite and Red Clay are difficult to obtain or the sedimentation process is challenging, you can make it without these two ingredients. Phyllite and Red Clay serve to enhance minerals and absorb oiliness. Therefore, if you omit these two materials, oiliness may form on the surface of the JS. In this case, simply skim off the oil from the top and use it.

He also developed self-manufactured natural pesticide technology that can reliably control the most difficult pests and diseases in organic farming. JADAM natural pesticides are completely new and different from pesticides that have been used so far.

 Things to be careful when using JADAM pesticide: 
 
∙ Before using any pesticide, always do a mixture test, concentration test, and mark test.
∙ Use soft water for the pesticide. Use soft water to make JWA and JHS. Use soft water to make JMS when it is for foliar application. 
∙ JS, start from 0.5ℓ(17 fl oz) for greenhouse crops and increase the amount of JS step by step 0.2ℓ(6.7oz). Do prior concentration test and pesticide mark test for all crops.
∙ JS uses 0.5ℓ(0.13 gal) for 500ℓ(132 gals) for persimmons, grapes, squash, and perilla, jujube.
∙ It is most effective to spray natural pesticides early in the morning. If you need to spray when moths active, adjust the spray time.
∙ Do concentration test and mark test when mixing JNP with commercial chemical fertilizer or pesticide.
∙ Wait at least seven days after using commercial pesticides before spraying JNP.
∙ By dissolving NaOH in a little water and adding it to pesticides, the insecticidal effect is enhanced. The pest mouth and leg contact the leaves of the crops and cause pain. Concentration damage can occur, so be careful.
