Problems solved by technology

Oxentrazone has high activity and needs to be used in a low amount, and because oxentrazone is a post-emergence herbicide, it also has the advantage of a wide application period, and oxentrazone also has the advantage of a broad herbicidal spectrum. It is used to control annual weeds in corn fields, and the effect is good, but the cost of using it alone is high, so it is not conducive to large-scale promotion and use
[0005] Both atrazine and acetochlor are herbicides used before emergence, and they are easy to cause phytotoxicity when used after emergence, and there is a requirement for soil moisture when used; sodium dimethyltetrachloride has special effects on broad-leaved grass and three-edged grass , can also control various dicotyledonous and some monocotyledonous weeds, but is ineffective against barnyard grass; Mainly for gramineous weeds, effective for broad-leaved grasses; bentazone, mesotrione, 2,4-dichlorophenoxyacetic acid, 2,4-dichlorophenoxybutyl acetate, 2 , Each of isooctyl 4-dichlorophenoxyacetate, terbuthylzine, and rimsulfuron-carbamide has its own unique herbicidal spectrum and weeds that cannot be controlled, and the weeding effect is not very ideal when used alone
