What are the precautions for using herbicides in wheat fields?
What should be noted when using herbicides in wheat fields? How should it be done? Applying herbicides to wheat requires the following strict practices: Strictly select herbicide varieties. There are many types of herbicides, and each herbicide has a certain spectrum of weed control. Some herbicides have a very narrow weed control spectrum, such as barban, which can only control wild oats; MCPA controls shepherd's purse, purslane, and wild oats very well, but its effect on cleavers is very poor; 2,4-D is effective against broadleaf weeds such as amaranth, but ineffective against grass weeds. Farmers should choose the right herbicide according to the most common weed species in the wheat field in order to achieve the desired effect. To control broadleaf weeds, herbicides such as chucaojing, dicaojing, tribenuron-methyl, and baijia mixture can be selected for good control results; however, metsulfuron-methyl, chlorsulfuron, and maicaoer can only be used early in wheat fields under a rice-wheat rotation system. If crops such as cotton, corn, peanuts, or beans are planted after rice, serious phytotoxicity will occur, leading to frequent incidents of almost total crop failure.
