Wheat sprayed with chlorofloxacin will die
Tangjianzhou, Baimahu Town, Jinhu County, said on March 28th that 10% of cyhalofop-butyl ester was mistakenly used as oxazolidine to control weeds in wheat fields and use 100 ml per mu. Wheat was just beginning to be jointed when spraying. He asked if there was any use for wheat that had been accidentally sprayed. Cyhalofop-butyl herbicide is a selective herbicide in paddy fields, mainly controlling grass weeds such as barnyardgrass and chinensis. The drugs are absorbed by the leaves and sheaths of weeds, and the phloem of the stems conducts, so that the synthesis of fatty acids is stopped, the growth and division of cells cannot be carried out normally, and the lipid structure of the membrane system and the like are destroyed, and finally the weeds die. The rate of death of weeds from the absorption of weeds from the weeds is slower and generally takes 1-3 weeks. 100 g/L cyhalofop-butyl ester EC is used to control grassy weeds such as madder and Qianjin in paddy field and direct seeding field. The recommended dosage per hectare is 75-105 grams, equivalent to 50-70 milliliters per acre. According to the personnel of the Dow AgroScience Company in the United States, cyhalofop-methyl has excellent selectivity for rice and can be rapidly degraded in rice to a diacid state that is inactive for acetyl-CoA carboxylase, and therefore has a high degree of rice Security. The drug is not selective for wheat. In wheat fields, 100 ml of 10% cyhalofop-butyl ester oil is sprayed by mistake. It is likely to cause serious injury to wheat and even cause dead seedlings. There are no effective measures to remedy this problem.
