Fomesafen is the main agent for controlling broad-leaved weeds in soybean fields. It often causes phytotoxicity due to improper use, and affects the growth of sensitive crops such as soybeans and post-planting pods. Causes of phytotoxicity (1) Harmful to soybeans. Fomesafen is used in the true leaf stage of soybeans to 1 compound leaf stage. When the amount of active ingredient per acre is less than 16 grams, it is safe for soybeans. Excessive drug usage or uneven application may cause phytotoxicity. In addition, the application of pesticides under conditions of high humidity (temperatures above 28°C) and low humidity (relative humidity below 65%) is also prone to phytotoxicity. Damaged leaves of soybean plants are burned and photosynthesis is not possible, and it is difficult for roots to absorb mineral nutrients from the soil. (2) Residual phytotoxicity. The residual period of fomesafen in the soil is longer. The overdose in the soybean field will cause phytotoxicity to sensitive crops of the rear pods, which will lead to the inhibition of plant growth, symptoms such as distorted swaying of leaves, chlorosis of leaf color, and death of plants when the damage is severe. The degradation rate of drugs in dry fields is slower than that of paddy fields, and therefore the phytotoxicity is heavier. Generally, 25 grams of fufentrix methylate is used per acre. After the wheat and barley are grown at intervals of 4 months, rice, cotton, peanuts, peas, beans, tobacco, and sweet potatoes need to be separated by 12 months. , tomato, onion, pumpkin, watermelon, pepper, eggplant, cabbage, radish, carrots, cabbage, cucumber, etc. need to be separated by 18 months, beet, rape, sunflower, potato, sorghum, etc. need to be separated by 24 months. Prevention and remedies (1) Replanting. Crops such as sorghum and live vegetables are harmed by the residue of fomesulfafen, which is generally difficult to emerge. In order to reduce losses, soybeans, mung beans and other crops should be changed as soon as possible. (2) Relieve phytotoxicity. After the occurrence of the phytotoxicity, it can be sprayed to protect 0.136% erythromycin B wettable powder, beneficial microbillion 30 billion/gram of Bacillus cereus wettable powder, and 4% chitosan water to promote the recovery of the plant. The degree of harm by the right amount of mixed drugs. (3) regulate the use of drugs. The amount of pure drug of fomesafen per acre cannot exceed 16 grams, and sandy soil and loam soil where the soil organic matter content in arid areas is less than 2% is not recommended. A uniform spray is required and no application is repeated.
