Hyung-tae Kim from Geochang. Crop: Greenhouse strawberries. Area: ≈ 0.28 acres. 3rd year of no synthetic pesticides used.
Mr. Hyung-tae Kim has been consistently using JADAM Microbial Pesticide (JMP) in his strawberry greenhouse. Through experience, he confirmed that ensuring the spray thoroughly covers even the undersides of the leaves is what determines the success of pest control. His practical know-how involves maintaining a regular weekly JMP application schedule after planting in September, and switching to JMP.S (JMP mixed with JADAM Sulfur, JS) as soon as mold begins to appear, tailoring the treatment to the growth stage of the strawberries.
Before JMP was invented, Mr. Kim unconditionally made and used the JADAM No. 12 Comprehensive Germicide and Pesticide (per 500 L: 1.2 L of JS, 10 L of JADAM Wetting Agent (JWA), and 15 L of JADAM Herbal Solution (JHS) made with ginkgo nuts). However, since planting his strawberry seedlings last September, he has been making and using JMP. After trying JMP, he found that spider mites were completely eradicated and no longer visible. It also controls aphids well, but some pale aphids remain on the undersides of the leaves. He believes the issue is that the spray did not thoroughly coat the undersides of the lower leaves near the ground while using the high-pressure sprayer. When controlling pests, it is crucial to spray thoroughly so that the solution coats the plants completely.
Looking at Mr. Kim's cultivation schedule, once the strawberry harvest ends in May, he floods the greenhouse, closes all the doors, and performs solarization. From July, he conducts fertigation with JADAM Microorganism Solution (JMS) about 4 times on the strawberry ridges before planting the strawberry seedlings in September. Prior to planting, he applies about 30 bags of Heuksari compost per 150 pyeong (≈ 0.12 acres). Once the strawberries begin to bloom, he dissolves compound fertilizer in water and injects it during fertigation.
After planting in September, he sprays 350 L of JMP once a week unconditionally without a second thought. Starting the pest control at dawn on Saturdays, when there are no strawberry deliveries, takes about 2 and a half hours. He has purchased several types of Yamaho nozzles and alternates between them to compare which one provides a finer mist and wider coverage. He uses only JMP from September to January, and switches to making and using JMPS by mixing in JS when mold begins to appear in January.

FAQ: Quick Fact
Q: What is the core secret behind Mr. Hyung-tae Kim's ability to increase pest control efficiency for his strawberries using only JMP?
A: Instead of frequently changing chemical products, the core to achieving stable control is spraying consistently once a week and repeatedly adjusting nozzles and spraying methods to ensure the solution thoroughly coats the undersides of the leaves.
