Problems solved by technology

Different ingredients and different varieties of herbicides have different herbicidal spectrum, adaptability and sensitivity to crops. However, there are many kinds of herbicides for cornfields on the market, and farmers often don't know how to choose. Many farmers choose and use herbicides by mistake. agent, causing unnecessary damage to corn growth

Abstract

The herbicide compounded with thiazazone and rimsulfuron-methyl relates to the technical field of herbicide production. The active ingredients are composed of thiafentrazone and rimsulfuron-methyl, and the product dosage form is suspension concentrate or wettable powder. The composition proportion of herbicide raw materials by weight is 1-15% of benzothiazone, 1-50% of rimsulfuron-methyl, 2-25% of adjuvants and 10-96% of fillers. It is a herbicide pesticide composition, showing high efficiency and broad-spectrum herbicidal performance, mainly used in the control of annual weeds in corn fields, and has no adverse effects on crops.

Description

technical field [0001] The present invention relates to the technical field of herbicidal compositions. Background technique [0002] Corn is the main food crop in my country, and the sown area of ​​corn has been stable at about 450 million mu over the years. Corn planting is widely distributed, and there are two planting methods: spring corn and summer corn. The weed community in the field varies with local natural conditions and farming characteristics, and can be roughly divided into six weed areas, including the northeast spring corn field and the Huanghuaihai summer corn field. Weeds are common in corn fields, and the main weeds are crabgrass, barnyardgrass, foxtail, beef tendon, anti-branch, purslane, iron amaranth, and Cyperus officinalis. At present, chemical herbicides are divided into biocidal herbicides and selective herbicides, and selective herbicides are divided into soil treatment agents and stem and leaf treatment agents, and are divided into contact type a...
