The herbicide flusulfamethoxazole is used in a large amount, or it is applied at a high temperature, which is easy to cause phytotoxicity to soybeans, and produces contact patches in leaves and the like. The application of the drug in the flowering stage of soybean is easy to adversely affect buds, flowers and young pods in the event of phytotoxicity. Quinoxaline has a better effect before the 4-leaf stage of grass weeds. When the grass age is large, it is necessary to increase the dose to obtain better control effect. When the grass age is too large or even the heading has begun, the drug is applied very effectively. difference. In the flowering stage of soybean, the weeds in the field are generally large, and the application of quizalofop-methyl is poor. Soybean fields should be basically out in the field, and weeds should be removed early before the 4-leaf stage.
Data link: Fomesafen is suitable for soybean and peanut fields to control broadleaf weeds and fragrant aconite, and it also has certain control effect on grass weeds. The drug can be absorbed by weed roots and leaves, causing it to die quickly and with yellow. The rain does not affect the efficacy after 4-6 hours of spraying, and it is safe for soybeans. It can prevent ramie, iron leeks, scutellaria, genus, ragweed, rape, leeks, medlar, genus, gypsophila, sylvestris, lobes, corn, corn, and Penn 蓼, Portulaca oleracea, thorn flower bud, wild carp, cassia, brocade, piglet, water-thorn needle, physalis, tianjing, borscht, medlar, trifolium, ramie, 宾The broadleaf weeds such as the cocklebur, the thorn, the cocklebur, and the cocklebur.
After soybean seedlings, 1~3 pieces of compound leaf stage, weeds 1~3 leaf stage, use 25% sulfamethasone water agent 68~132 ml per acre, spray evenly on water 20~30 kg. It is better to add an appropriate amount of nonionic surfactant to the liquid.
Fomesafen has a long-lasting effect in the soil. If the dosage is high, the sensitive crops planted in the second year, such as cabbage, millet, sorghum, sugar beet, corn, millet and flax, have different degrees of phytotoxicity. At the recommended dose, no ploughing of corn and sorghum has a slight impact. The dosage should be strictly controlled, and the crop should be selected after safety.
