Weeding composition containing pyrazolone compounds and application of weeding composition

Abstract

The invention belongs to the field of pesticides, and particularly relates to weeding composition containing pyrazolone compounds and an application of the weeding composition. The weeding composition comprises an effective weeding quantity of an active component A, an active component B and a safener compound C, wherein the active component A is one of general formulae represented in the specification, R1 represents hydrogen atoms, R2 represents methyl, R3 represents ethyoxyl, R4 represents helium atoms, and R5, R6 and R7 represents alkyl and the like; the active component B is selected from one or more of compounds as follows: 1) a triazine compound: ametryn; 2) diphenyl ether compounds: oxyfluorfen and the like; the safener compound C is selected from one or more of compounds as follows: C1: isoxadifen-ethyl and the like. With the adoption of the composition, the problems about weeds including barnyard grass, eleusine indica, horseweed herb and the like during destructive weeding and sugarcane field weeding can be solved effectively, and the composition has the characteristics that the weeding spectrum is enlarged, the application amount is reduced, the composition is safe to crops, herbicide resistant weeds can be controlled and the like.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition containing pyrazolone compounds and an application thereof. 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. 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 resistance, and is one of the most effective methods to solve the above problems. [0003] Hydroxyphenylpyruvate dioxygenase (HPPD) was discovered after inhibitors of acetyl-CoA carboxylase (ACCase), acetolactate synthase (ALS) and protoporphyrinogen oxidase (Protox), etc. Another...
