Weeding water suspension agent

Abstract

The invention discloses a weeding water suspension agent for wheat fields. The weeding water suspension agent is prepared from the following components in percentage by weight: 5-10% of fenoxaprop-p-ethyl, 10-50% of benazolin, 3-5% of cloquintocet-mexyl, 8% of surfactant pluronic 125, 5% of propylene glycol, 8% of propylene glycol, 1% of methyl esterified plant water, and less 100% of water. The weeding water suspension agent has remarkable effects; compared with a florasulam suspending agent and benazolin cream, the preparation has the advantages that water is used as a solvent, and the weeding water suspension agent is friendly to environment, unlikely on fire during transportation, high in safety, low in cost and safe to field crops; and a field weed preventing effect, a fresh weight preventing effect and a comprehensive fresh weight preventing effect are all enhanced. The weeds during the whole growth period of a crop can be removed after applying the weeding water suspension agent for only once, and the weeding water suspension agent is safe to next-stubble crops. The weeding water suspension agent is an ideal herbicide for postemergence treatment of wheat seedlings.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a herbicide aqueous suspension. Background technique [0002] Fenoxaprop-ethyl, chemical name: (R)-2-[4-(6-chloro-1,3-benzoxazol-2-yloxy)phenoxy ethyl propionate, molecular formula: C18H16CINO5 The molecular weight is 361.78, it is a selective post-emergence herbicide. Plus safener cloclofenac, mainly used for controlling annual gramineous weeds in wheat fields. Safe for wheat. It is a post-emergence stem and leaf treatment agent and an important new variety of herbicide in wheat fields. It is mainly used to control wild oats, kangaroo, foxtail, oats, ryegrass, bluegrass, barnyardgrass, spontaneous corn, crabgrass and other weeds. Chemical name: 4-chloro-2-oxobenzothiazepine -3-ylacetic acid; molecular formula C9H6CINO3S, molecular weight [0003] For 243.6, organic heterocyclic herbicides. It is a kind of post-emergence conductive herbicide with specific effect. After application...

AI Technical Summary

Problems solved by technology

At present, the main herbicides used to control weeds in wheat fields are 2.4 butyl ester, florasulam, etc. Due to long-term use, the resistance increases, resulting in a large amount of pesticides, polluting the environment, and increasing the cost of pesticide application for farmers

However, there are few reports on the compounding of florasulam and fenoxen to control weeds in wheat fields
