Embodiment Construction

[0016] The paddy field herbicide compounded by bicyclic sulcotrione, the key is that each component in the herbicide includes by weight percentage: active ingredient 5-80%, adjuvant 5-20%, filler 5-80%, wherein The first active ingredient is bicyclic sulcotrione, and the second active ingredient is acetochlor, metolachlor, propachlor, pretilachlor, butachlor, mefenamide, penoxsulam, Any one of cyhalofop-ethyl, quinclorac, bensulfuron-methyl, pyrazosulfuron-methyl, etesulfuron, clomazone, fenoxaprop-ethyl, mefentrazone, and isoproturon, the first The weight ratio of one active ingredient to the second active ingredient is (1:8)˜(8:1).

[0017] The dosage form of the composition is a wettable powder, or a suspension, or a water-dispersible granule.

[0018] In the wettable powder, the auxiliary agent includes 1-6% of wetting agent and 1-6% of dispersant.

[0019] In the suspending agent, auxiliary agents include 1-6% of wetting agent, 1-6% of dispersant, 1-3% of thickener, 1-3...

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...
