Herbicide composition containing Benzuofucaotong and application thereof

Abstract

The invention belongs to the field of pesticides, and in particular relates to a herbicide composition containing Benzuofucaotong (4-(having a chemical formula name of 2-chloro-4-methanesulfonyl-3-(2,2,2-trifluoroethoxy)methyl)benzoyl-1-ethyl-1H-pyridin-5-yl-1,3-dimethyl-1H-pyridine-4-carboxylate) and application thereof. The herbicidal composition comprises a herbicidally effective amount of active ingredient A and active ingredient B, wherein the ingredient A is Benzuofucaotong, and the ingredient B is selected from one or more of the following compounds: VLCFA, PPO, PSII, ALS, microtubule assembly, HPPD, PDS, lipid synthesis, EPSPS, GS, PSI, DHP inhibitors and synthetic hormones. The composition can effectively control weeds in a crop field, such as descurainia sophia and malachium aquaticum, and has the characteristics of expanding the weed killing spectrum, reducing the application amount, being safe to crops, generating synergistic effects, and solving resistant weeds.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition containing fenfluroxyzone and its application. Background technique [0002] Chemical herbicide is the most economical and effective means of controlling weeds in farmland, but long-term continuous high-dose use of a single species or single mode of action of chemical herbicides is likely to cause problems such as weed resistance and resistance evolution. [0003] The chemical structural formula of fenflurzone is It is a newly developed HPPD inhibitor herbicide for post-emergence stem and leaf treatment of corn fields. It has excellent biological activity and can effectively control a variety of malignant weeds in corn fields. [0004] Reasonable compounding or mixing of herbicide compounds has the advantages of expanding the spectrum of weeds, improving the control effect, delaying the occurrence and development of weed resistance and drug resista...
