Nowadays, the application of herbicides in agricultural production is more and more extensive, and the herbicides are becoming more and more serious. How to avoid herbicide phytotoxicity?
Pay attention to the choice of herbicides, herbicides have a strict range of use, sometimes a word difference, it may cause a major disaster. For example, butachlor and acetochlor, bensulfuron-methyl and chlorsulfuron-methyl, although only one word, one for paddy fields and one for dry land. Different types of crops, or different growth stages of the same crop, require different types of herbicides. Therefore, you must pay attention when purchasing medicine. For herbicides that have never been used, first pass a small area test or understand the safety of the use of the effect, and then decide whether to use.
Avoid herbicide injury methods
Pay attention to the concentration of herbicides. Some farmers like to increase the concentration of herbicides, which is very dangerous. Increasing the concentration at will can cause phytotoxicity to occur.
Attention to pesticide drift damage Each crop has some sensitive pesticides, such as grapes, soybeans and other dicots sensitive to 2,4-D butyl ester, rice chlorosulfuron-methyl, sensitive, cucumber, spinach and other crops Amine sensitive, etc., as long as a trace amount of herbicide for sensitive crops will cause phytotoxicity.
Note that some herbicides have long residual effects and have an impact on sensitive crops. Therefore, when selecting weeding, it is important to consider what crops are to be planted in the next season.
