Abstract

The invention discloses a herbicide compound with broad-spectrum weeding function. The herbicide compound is different from other prior agricultural chemical herbicide. The effective component of the compound herbicide consists of ester Cyhalofop-grass and double grass ether, and uses milk oil as the product agent. The compound herbicide has the material weight percentage that the ester Cyhalofop-grass is 5-25 percent, the double grass ether is 3-25 percent, the emulsifying agent is 5-15 percent, and the solvent is 35-87 percent. The invention is a herbicide agricultural chemical compound which can perform high-effective and broad-spectrum weeding capability, is mainly used to prevent and remove various ruderal in the rice direct seeding filed, and has no blight on the crops. The herbicide compound with the broad-spectrum weeding function is applicable for preventing and removing various ruderal in the rice direct seeding filed.

Description

technical field [0001] The invention is a herbicide composition with broad-spectrum herbicidal effect, exhibits high-efficiency and broad-spectrum herbicidal performance, and is mainly used in the control and control of various weeds in rice direct-seeding fields without adverse effects on crops. The herbicide composition is different from other existing pesticide herbicides. Background technique [0002] Rice is the main food crop in my country, and the country's rice planting area has been stable at about 450 million mu for many years. With the continuous popularization and application of rice light cultivation techniques, the development of direct-directed rice is particularly rapid. Due to its huge advantages of saving labor and cost and liberating rural productivity, it has gradually become a rice cultivation method with broad development prospects in major rice producing areas in my country. Due to the cultivation methods and characteristics of direct-directed rice f...
