A kind of mesotrione compound herbicide

Abstract

The invention provides a mesotrione compound herbicide. The compound herbicide contains three active ingredients, namely mesotrione, bentazone and bispyribac-sodium, wherein the weight ratio of mesotrione to bentazone to bispyribac-sodium is (1-30):(1-30):(1-20). The herbicide is safe, has high speed, wide weed control spectrum and long herbicide application period and is slightly affected by the environment.

Description

technical field [0001] The invention relates to a compound herbicide of mesotrione. Background technique [0002] Rice is an important food crop in my country, which is related to the national economy, the people's livelihood and the country's food security. The chemical name of bentazone is: 3-isopropyl-(1H)-benzo-2,1,3-thiadiazin-4-one-2,2-dioxide, bentazone is a photosynthetic Inhibitors are mainly absorbed through leaves. After spraying on stems and leaves in dry fields, they first penetrate into chloroplasts through leaves to inhibit photosynthesis. When used in paddy fields, they can also be absorbed by roots and spread to stems and leaves. It cannot be absorbed by ungerminated seeds, and the young shoots absorb little medicine during the process of passing through the soil layer, so it can only be used by spraying stems and leaves after the weeds emerge. The chemicals that fall into the soil are rarely adsorbed, and are easy to drip into the deep layer of the soil, ...

Problems solved by technology

It cannot be absorbed by ungerminated seeds, and the young shoots absorb little medicine during the process of passing through the soil layer, so it can only be used by spraying stems and leaves after the weeds are unearthed

The chemicals that fall into the soil are rarely absorbed, and are easy to drip into the deep layer of the soil, and are also easily decomposed by soil microorganisms, so they are not suitable for soil treatment.
