Abstract

The invention relates to a herbicidal composition containing metribuzin and haloxyfop-R-methyl. The effective components of the herbicidal composition are metribuzin and haloxyfop-R-methyl in a weight part ratio of 30:1-1:30. According to the invention, the metribuzin and haloxyfop-R-methyl compounded composition has an obviously increased effect on barnyard grass and crabgrass, has an improved herbicidal effect, expands the herbicidal spectrum, and is suitable for preventing and killing off annual weed in potato field, tomato field and soybean field.

Description

technical field [0001] The invention belongs to the technical field of agricultural weeding, and specifically relates to a herbicidal composition with metrizone and high-efficiency haloxyfop as active ingredients, which is suitable for controlling annual weeds in potato fields, tomato fields and soybean fields. Background technique [0002] With the phase-out of highly toxic pesticides, new pesticides with high efficiency, low toxicity, safety, and environmental friendliness are needed. At the same time, the long-term use of pesticides has resulted in the resistance of pests and weeds, and the requirements for control chemicals are getting higher and higher. It is necessary for pesticide research and development personnel to develop efficient and safe new agents to meet the control requirements. Since the development of pesticides in my country has just started, and the varieties of pesticides with independent intellectual property rights cannot meet the needs, the developme...
