"Pesticide treatment by fertilizer" is a new technology developed in recent years. It mainly uses fertilization to kill or repel pests. This can save medicine and prevent phytotoxicity, and also has fertilization effect, and does not harm natural enemies or pollute the environment. . Farmer friends may wish to give it a try.
First, the urine washing mixture insecticide acres with urea 250 to 500 grams, plus washing powder 100 grams, 50 kg water, mixed and sprayed after spraying, can control fruit trees, crops, vegetable gardens, red spiders, aphids and other pests, The effect of controlling red spiders can reach about 90%, and the effect of controlling aphids can reach more than 95%. Not only pollution-free, but also topdressing.
Second, fertilizer mixed insecticide Fertilizer and pesticide mixed application, pest control is extremely powerful. For example, when using 1% urea solution for root external application, add 0.1% concentration of 50% dichlorvos EC or 40% stearin EC to spray, and control the red spider on cotton and flower to 92. From % to 96%, the control effect on aphids can reach 98% or more, and other pests can be treated.
Third, the grass and ash liquid insecticide with 10 kg of grass ash with water 50 kg, soak for 1 day and night, take the filtrate spray, can effectively control fruit trees, crop aphids, and can enhance the crop's lodging resistance and the resistance of young fruit trees to wind.
4. Silicon-calcium fertilizer insecticidal silicon-calcium fertilizer is a new type of fertilizer. When the crop is fertilized, it can be used or mixed with silicon-calcium fertilizer. After the crop is absorbed, the silicon will accumulate in the epidermal cells of the crop to form a very hard surface. The cortex makes it difficult for pests to invade, thereby enhancing the resistance of the crop. Applying 30 to 40 kilograms of silicon-calcium fertilizer per acre can greatly reduce the harm of armyworms to corn, sorghum, soybeans (soybeans) and kidney beans.
5. Nitrogen fertilizers, such as urea, ammonium bicarbonate and ammonia, have certain volatility and have certain stimulating, corrosive and fumigating effects on pests, especially for small spider mites, spider mites and mites. The pests with weak resistance are especially effective. When the pest occurs, use 2% urea solution, 1% ammonium bicarbonate solution, or 0.5% ammonia solution to spray the roots, spray once every 7 days, and spray 2 to 3 times. Effective control of pests.
