Paddy field herbicide compounded with benzobicylon

Abstract

A paddy field herbicide compounded with benzobicylon comprises the following materials by weight: 5 to 80 percent of effective components, 5 to 20 percent of additives and 5 to 80 percent of filling materials, wherein the first effective component is benzobicylon; the second effective component is any one of acetochlor, metolachlor, propisochlor, pretilachlor, butachlor, mefenacet, penoxsulam, fenpyroxim, quinclorac, bensulfuron, pyrazosulfuron, cinosulfuron, clomazone, fenoxaprop-P-ethyl, carfentrazone and isoproturon, wherein the weight ratio between the first effective component and the second effective component is (1:8) to (8:1). The paddy field herbicide has the technical effects that the use is economical and efficient; the safety is high; the control effect of weeds of the grass family, the broad-leafed family and the sedge family in the paddy field is improved; particularly, the control effect of weeds of the broad-leafed family is remarkably improved; the herbicide controlling spectrum is broadened; the safety degree for paddy rice is improved; the dosage as well as the control cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a herbicide, in particular to a paddy field herbicide compounded with bicyclic sulcotrione. Background technique [0002] my country has a long history of planting rice and has a vast territory. It is one of the main rice producing countries in the world. The weeds that harm rice fields mainly include barnyardgrass, daughter daughter, paspalum, crabgrass, foxtail, goosegrass, oat grass, wild oats and other gramineous weeds; Broad-leaved weeds such as Serving Vegetables, Festival Vegetables, Thin Beetle Leaf, Hollow Lotus Seed Grass, and Annual Capsules, and Sedges such as Alien Sedge, Broken Rice Sedge, Cow Felt, Sunshine Buddha Grass, Cyperus Cyperi, and Water Centipede Bicyclic sulcotrione is a post-emergent herbicide for albino rice fields of bicyclooctane, which has good control effect on gramineous weeds in paddy fields, but poor control effect on broad-leaved weeds. Ther...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problem that existing paddy field herbicides have poor control effect on broad-leaved weeds. In order to solve this problem, we have designed a paddy field herbicide compounded by bicyclic sulcotrione, which improves the The control effect on gramineous weeds, broad-leaved weeds and sedge weeds in rice fields, especially the synergistic effect on the control of broad-leaved weeds is very significant, broadening the herbicidal spectrum and reducing the dosage. Save the cost of prevention and control, and reduce the pollution to the environment
