The composition comprises two components A and B, wherein the component A is a formula (I) or a formula (II) compound, the component B is a formula (III) or a formula (IV) compound, and the weight ratio of the component A to the component B is 50:1-1:50; the composition is very safe for rice, can reduce damages to rice, and does not influence control effects of a herbicide on weeds, and at the same time the herbicidal composition has a certain promotion effect for growth of rice.

Description

technical field [0001] The invention belongs to the field of herbicides, in particular to a herbicide composition safe for rice. Background technique [0002] Barnyardgrass is a worldwide vicious weed and one of the most dangerous weeds in my country's farmland. According to the "Distribution and Hazards of Major Weeds in Chinese Rice Fields" published by the National Farm Weeds Survey Group, barnyardgrass alone has damaged 14 million hectares of rice fields, making it the most serious weed in my country's rice fields. In recent years, rice barnyardgrass has become increasingly resistant to insecticides. Li Yongbing and Huang Bingqiu summarized the research progress of barnyardgrass resistance in my country, showing that barnyardgrass in paddy fields in my country has been resistant to traditional paddy field herbicides such as propanil, clopyr, butachlor, quinclorac and triazines. have developed resistance. "China Pesticide Science" reported in 2009 that when farmers in s...
