Embodiment 1

[0091] Weigh 3% cyhalofop-methyl, 3% saflufenacil, 3% bentazone, 1.5% NNO, 1% TERSPERSE2500, 2% emulsifier T-60, 3% agricultural milk 700#, 0.1% xanthan gum , 5% propyl alcohol, 2.5% formaldehyde, 0.3% organic silicon defoamer, deionized water added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare 9% saflufenacil-cyhalofop-methyl-benzazone suspension concentrate.

Embodiment 2

[0093] Weigh 15% cyhalofop-methyl, 8% saflufenacil, 7% bentazone, 3% Nongru 700#, 2% Nongru 1601#, 1.5% TERSPERSE 2500, 2.5% TERSPERSE 2425, 0.2% Xanthan Glue, 3% white carbon black, 5% ethylene glycol, 0.3% benzoic acid, 2.5% organic silicon defoamer, deionized water added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 30% saflufenacil-cyhalofop-methyl-benzazone suspension concentrate.

Embodiment 3

[0095] Weigh 2% cyhalofop-methyl, 2% saflufenacil, 2% bentazone, 2% diffusing agent NNO, 3% Nongru 2201#, 8% BY-110, 1% TERSPERSE 2500, 1% silicic acid Magnesium aluminum, 3% propylene glycol, 15% epoxidized soybean oil, and soybean oil are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare 6% saflufenacil-cyhalofop-methyl-benzazone dispersible oil suspension concentrate.

Abstract

The invention discloses a weedicide composition containing pyribenzoxim, cyhalofop-butyl and bentazone. The weight ratio of the three active ingredients of the pyribenzoxim, the cyhalofop-butyl and the bentazone in the weedicide composition is (10 to 25):(20 to 40):(1 to 10), and is preferably (15 to 20):(25 to 35):(4 to 8). The accumulation weight of the pyribenzoxim, the cyhalofop-butyl and the bentazone accounts for 31 to 85 percent of the total weight of the composition, and is preferably 45 to 55 percent. The pyribenzoxim, the cyhalofop-butyl and the bentazone are subjected to new ingredient proportioning and combination, so that the medical effect of the composition is enhanced; meanwhile, the weed prevention and control spectrum is expanded; commelina commelis, gramineae difformed galingale herb and gramineae echinochloa of direct seeding paddy rice can be prevented and removed through once weedicide application; the number of weedicide application times can be reduced; the prevention and control cost is reduced; the weed resistance generation is reduced; the safety on crops is high; the safety requirements of the pesticide preparation are met.

Description

technical field [0001] The invention relates to a herbicide composition containing saflufenacil, cyhalofop-ethyl and bentazone, in particular to a herbicide for preventing and treating annual weeds and barnyardgrass in direct seeded rice fields, which is composed of pyrimidine oxime A ternary herbicide composition consisting of fluorfen, cyhalofop-ethyl and bentazone as active components. Background technique [0002] Since around 1950 when 2,4-D and 2M4Cl were widely used to control broad-leaved weeds in paddy fields, the varieties of herbicides used in paddy fields have developed rapidly, and the varieties have been continuously improved. Diphenyl ethers and thioamino groups have emerged successively. Formic esters, amides, quinoline carboxylic acids, sulfonylureas and other herbicides have formed a relatively complete chemical herbicide system suitable for different cultivation methods of rice, and have become indispensable and very important measures for increasing rice ...
