"Fighting insects with fertilizers" is a new technology developed in recent years. It mainly uses fertilizing methods to kill or repel pests. It not only saves medicines, prevents damage, but also has fertilizing effect. It does not harm natural enemies and does not pollute the environment. . Farmer friends may wish to try. First, the urine washing mixture insecticide mu urea 250 to 500 grams, plus detergent 100 grams, watered 50 kilograms, mixing and spraying after mixing, can prevent fruit trees, crops, vegetable gardens, spider mites, locusts and other pests, The effect of controlling spider mites can reach about 90%, and the effect of controlling aphids can reach more than 95%. Not only no pollution, but also can be topdressing. Second, fertilizer and mixed pesticides and pesticides mixed application, pest control power is extremely strong. For example, when using a 1% urea solution for root dressing, plus a 0.1% concentration of 50% dichlorvos EC or 40% arsonite EC, the control effect on spider mites on cotton and flowers can reach 92%. From 96% to 96%, the control effect on aphids can reach more than 98%, and it can also treat other pests. Third, grass ash liquid insecticide with 10 kg of grass ash mixed with 50 kg of water, soak 1 day and night, take the filtrate spray, can effectively prevent fruit trees, crop aphids, and can enhance the resistance of the crop lodging and wind resistance of young fruit trees. Si-Ca-Calcium Fertilizer Si-Ca-Calcium fertilizer is a new type of fertilizer. When the crops are fertilized, Si-Ca fertilizer can be used or mixed in. When the crops absorb the silicon elements, they will accumulate in the crop epidermal cells, forming a very hard table. The cortex makes it difficult for pests to invade, thereby enhancing the crop's resistance. Applying 30 to 40 kilograms of calcium-silicon fertilizer per acre can greatly reduce the damage of armyworm, corn, sorghum, soy beans, and kidney beans. Fifth, nitrogen fertilizer, urea, ammonium bicarbonate, ammonia, the three kinds of nitrogen fertilizer, has a certain degree of volatility, the pest has a certain degree of stimulation, corrosion and fumigation, especially for spider mites, leafhoppers, locusts and other small size Pests with weak drug resistance are particularly effective. When pests occur, use 2% urea solution, or 1% ammonium bicarbonate solution, or 0.5% ammonia solution for root spray, spray once every 7 days or so, and spray 2 or 3 times. Effective control of pests.
