If you want to grow well, only spray at the right time to prevent prolonged, premature aging and pests.
Peanuts tend to be prolonged in the middle and late growth stages, such as excessive precipitation or excessive fertilization. For peanut fields with a long trend, the first stage of pod formation should be sprayed with 1.5% paclobutrazol wettable powder 30~40 g to 50 kg of water to inhibit vegetative growth and promote reproductive growth.
For peanuts that cause premature aging due to insufficient fertilizer and water, 0.2%~0.3% potassium dihydrogen phosphate solution can be sprayed at the initial stage of pod-to-fruit filling. For plots with poor plant growth and yellow leaves, add 1% per acre~ 2% of the urea solution is mixed and sprayed every 7~10 days, and even sprayed 2~3 times. In case of drought, water should be timely to prevent premature aging of plants.
The main disease in the middle and late stages of peanuts is leaf spot disease. The pathogens form brown or black lesions on the leaves. In severe cases, the petiole and stem are covered with lesions, affecting photosynthesis, causing premature senescence of plants, which seriously affects the yield and quality of peanuts. Generally, it can be sprayed with 70% methyl thiophanate WP 800 times per acre, and sprayed 2~3 times. The cockroach adult chafer can be sprayed with 45% phoxim 800 times solution.
