Oxaziclomefone compound herbicide

Abstract

The invention relates to an oxaziclomefone compound herbicide. The compound herbicide is characterized by containing three active ingredients, namely oxaziclomefone, bentazone and ethoxysulfuron, wherein the weight ratio of oxaziclomefone to bentazone to ethoxysulfuron is (1-30): (1-30): (1-20). The herbicide provided by the invention has the advantages of safety, high speed, broad weed control spectrum, long drug applying period and little environmental influence.

Description

technical field [0001] The invention relates to a compound herbicide of oxaziclozone. 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...

AI Technical Summary

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.
