Problems solved by technology

[0004] 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

Abstract

The invention discloses a herbicide composite. The herbicide composite comprises topramezone used as a main material and an auxiliary material which contains one or more than one of atrazine, fluroxypyr, bentazone, dicamba, nicosulfuron, mesotrione, 2,4-dichlorophenoxyacetic acid, 2,4-dichlorophenoxyacetic acid butyl ester, 2,4-dichlorophenoxyacetic acid iso-octyl ester, terbuthylazine, MCPA-sodium, foramsulfuron and acetochlor. The herbicide composite is a novel herbicide composite with good weeding effect.

Description

technical field [0001] The invention relates to a herbicide composition, in particular to a herbicide composition for controlling weeds in corn fields. Background technique [0002] Chinese patent document CN102017962A discloses "a herbicide composition containing fenfentrazone and meridoxetin methyl ester". A herbicide composition containing fenfentrazone, methyl metricloxamate and sodium dimethyltetrachloride", the active ingredients of which are fenfentrazone, methyl metricloxamate and sodium dimethyltetrachloride. In addition, there are other herbicides disclosed in patent documents, among which there are many herbicide compositions with multiple active ingredients. Common active ingredients mainly include atrazine, nicosulfuron, and paraquat. [0003] Benfentrazone is a triketone herbicide for post-emergence stem and leaf treatment. It is absorbed through roots, seedlings and leaves, and is transmitted to the top and base of the plant to the meristem, inhibiting 4-HPPD...
