Abstract

The invention discloses a rice post-emergence compound herbicide containing ipfencarbazone and benthiocarb. Effective components of the compound herbicide comprise ipfencarbazone and benthiocarb, wherein the weight ratio of ipfencarbazone to benthiocarb is 1 to (1 to 9). The compound herbicide is capable of controlling and removing annual gramineous weeds such as leptochloa chinensis and barnyardgrass, is also capable of controlling and removing broadleaf weeds and sedge weeds, is obvious in weeding effect, especially has obvious synergistic action on leptochloa chinensis and barnyard grass,is free of influence on afterreap crops, can be applied to pre-emergence sealing treatment, can also be applied to post-emergence weeding, and is taken as an ideal herbicide.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a post-emergence compound herbicide for rice containing trifenazole and grass-carban. Background technique [0002] Rice is not only the most important food crop in my country, but also one of the main food crops in the world. Nearly half of the world's population, including nearly all of East and Southeast Asia, depend on rice for food; its production is also found on every continent except Antarctica. Regardless of the planting area and output, it ranks first in my country's food crops. There have always been a large number of weeds in the paddy fields of all rice-growing areas in my country. The area of ​​moderate weed damage accounts for more than 46% of the total planting area, of which more than 11.5% is severely damaged, resulting in a loss of more than 20 billion kilograms of grain every year. Therefore, the use ratio of herbicides in domestic paddy fields is almost...
