Abstract

The invention belongs to the field of pesticide and particularly relates to a sorghum field weeding composition containing biscarfentrazone-ethyl and application thereof. The sorghum field weeding composition comprises the effective weeding quantity of an active ingredient biscarfentrazone-ethyl and the effective weeding quantity of an active ingredient B. Please see the structural formula of the active ingredient biscarfentrazone-ethyl in the description. The active ingredient B is selected from one or more of HPPD inhibitor mesotrione and quinoline carboxylic acid quinclorac. The composition can effectively prevent and eliminate broad-leaf weeds and part of grassy weeds in a sorghum field and has the advantages of enlarging the weeding spectrum, reducing the application amount and being safe to crops.

Description

technical field

[0001] The invention belongs to the field of pesticides, and in particular relates to a sorghum field herbicidal composition containing bisfentrazone and an application thereof. Background technique

[0002] Hydroxyphenylpyruvate dioxygenase (HPPD) was discovered after inhibitors of acetyl-CoA carboxylase (ACCase), acetolactate synthase (ALS) and protoporphyrinogen oxidase (Protox), etc. Another class of new herbicides. The action of HPPD inhibitors is characterized by broad-spectrum herbicidal activity, which can be used both before and after emergence, and the weeds will die after albinism. Although its symptoms are very similar to those of carotenoid bioinhibitors, its chemical structure characteristics such as polarity and degree of ionization are significantly different from those of known carotenoid bioinhibitors. Among them, bisfentrazone is a typical HPPD inhibitor.

[0003] Sorghum belongs to economic crops, Gramineae and sorghum are annual herbac...
