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 invention discloses a benzene thiazole oxadiazon and rimsulfuron compound herbicide, and relates to the technical field of herbicide production. Effective components comprise benzene thiazole oxadiazon and rimsulfuron; the product dosage form is a suspending agent or wettable powder. The compound herbicide consists of the components in percentage by weight: 1 to 15 percent of benzene thiazole oxadiazon, 1 to 50 percent of rimsulfuron, 2 to 25 percent of auxiliaries and 10 to 96 percent of filler. The herbicide pesticide composition shows efficient and broad-spectrum weeding performance, is mainly applied to prevention and removal of annual weeds in a corn field, and does not have a harmful effect on crops.

Description

technical field [0001] The present invention relates to the technical field of herbicide compositions. Background technique [0002] Corn is the main food crop in my country, and the country's corn sown area has been stable at about 450 million mu for many years. Corn planting is widely distributed, and there are two planting methods of spring corn and summer corn. The weed community in the field varies with the local natural conditions and farming characteristics, and can be roughly divided into six weed damage areas: the northeast spring corn field weed damage area, the Huanghuai sea summer corn field weed damage area. Weeds are common in corn fields, and the main weeds are crabgrass, barnyardgrass, foxtail, goosegrass, amaranth, purslane, amaranth, Cyperus rotundum, etc. At present, chemical herbicides can be divided into killing herbicides and selective herbicides, and selective herbicides can be divided into soil treatment agents and stem and leaf treatment agents, an...
