Will the use of 75% tribenururon-methyl per acre and weeding of 10% bensulfuron-methyl per acre in March-April in March-April will have an impact on post-planting soybeans? Addition of insecticides and fungicides will adversely affect wheat seedlings. Impact?
Compared to sulfonylurea herbicides such as chlorsulfuron and metsulfuron, tribenuron is a short-lived drug in sulfonylurea herbicides, but its residual period in soil is also relatively low. When the crop grows to be soybean, cotton, peanut and other dry crops, the amount of pure medicinal mu should not exceed 1.5 g in general, and it should be applied before winter, and pesticide application in the spring is likely to cause damage to the rear pods, especially in spring. When the application is too late, there is a greater risk of injury to crops such as cotton, soybeans, and peanuts. In Anhui, Jiangsu and other places, in addition to the spring wheat in the end of February and early spring temperature recovery, the wheat is in the turning green period before the jointing. The application of pesticides was too late. After the wheat began to be jointed, it not only reduced the safety of the wheat seedlings but also made it more likely to cause phytotoxicity to the crops.
Tribenuron-methyl and bensulfuron-methyl have good safety to wheat seedlings, and they can usually be mixed with commonly used insecticide fungicides in wheat fields. Normal mixed use has no adverse effect on wheat seedlings.
The wheat fields, soybeans, and peanuts in the wheat fields are best not to be treated with herbicides such as tribenuron-methyl, bensulfuron-methyl, etc., especially when it is removed in the spring, so as not to cause phytotoxicity to the crops. It is best to control the stem and leaf treatment agent such as fluoxyl, flufenoxa, etc. according to the grassy phase. The residual period of these medicines in the soil is very short, and there is no adverse effect on the posterior condyle.
Fluroxypyr is safe for wheat seedlings and can also be used in the early stages of jointing wheat, and it has good compatibility with insecticides commonly used in wheat fields. Fluoxazone has relatively high requirements for pesticide application. Do not mix it with other drugs at will, especially if it cannot be mixed with emulsifiable concentrate preparations.
