Problems solved by technology

[0005] Both atrazine and acetochlor are herbicides used before emergence, and they are easy to cause phytotoxicity when used after emergence, and there are requirements for soil moisture when used; Methyl tetrachloride sodium salt has special effects on broad-leaved grass and three-edge grass, and can also control various dicotyledons and some monocotyledonous weeds, but it is ineffective against barnyard grass; paraquat and fluroxypyr control most broad-leaved Weeds, but ineffective against gramineous weeds; nicosulfuron is mainly for gramineous weeds, effective against broadleaf grasses; bentazone, mesotrione, 2,4-dichlorophenoxyacetic acid , butyl 2,4-dichlorophenoxyacetate, isooctyl 2,4-dichlorophenoxyacetate, terbuthylazine, and rimsulfuron-carbamide each have their own unique herbicidal spectrum And weeds that cannot be controlled, the weeding effect is not very ideal when used alone
