[0029] water emulsion

[0030] 1.1) active ingredient A, active ingredient B is pendimethalin

[0031] The formula is composed of: 2.5% A+25% pendimethalin+6% cyclohexanone+4% phenylethylphenol polyoxyethylene ether phosphate triethanolamine salt+2% phenylethylphenol polyoxyethylene ether+3% Castor Oil Ethoxylate + 3% Glycol + Water Top Up.

[0032] 1.2) Active ingredient A and active ingredient B are trifluralin

[0033] The formula is composed of: 2.5% A+42.5% trifluralin+8% cyclohexanone+3% nonylphenol polyoxyethylene ether phosphate triethanolamine salt+2% phenylethylphenol polyoxyethylene ether+2% castor oil Polyoxyethylene ether + 3% glycol + water make up.

[0034] The above water emulsion processing process: put the original drug and solvent into the batching kettle, stir and dissolve until completely transparent, then add emulsifier, stir evenly to form an oil phase, and then pump ethylene glycol, defoamer and water into the shearing kettle , and finally in the sh...

Abstract

The invention relates to the technical field of pesticides and particularly relates to synergistic weeding composition containing dicarfentrazone-ethyl and dinitraniline type compounds. The synergistic weeding composition comprises an active ingredient A and an active ingredient B which are effective for weed control, wherein the active ingredient A is a compound dicarfentrazone-ethyl, and the active ingredient B is one or more of dinitraniline type compounds, namely, pendimethalin, trifluralin and butralin. The synergistic weeding composition can be used for controlling broad leaved weeds such as descurainia sophia, shepherd's purse, lithospermum arvense and the like and grassy weeds such as alopecurus aequalis, lolium multiflorum, bromegrass and the like and has a remarkable control effect on resistant weeds.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic herbicidal composition containing bisfentrazone and dinitroaniline compounds. Background technique [0002] The use of herbicides to control weeds is the most economical and effective means of weed control in farmland. However, long-term continuous high-dose use of a single species or a single mode of action of chemical herbicides is likely to cause problems such as weed resistance and resistance evolution. Reasonable compounding or mixing of herbicide compounds has the advantages of expanding the spectrum of weeds, improving the control effect, delaying the occurrence and development of weed resistance and drug resistance, and is one of the most effective methods to solve the above problems. [0003] Bisfentrazone is a newly developed herbicide for broad-leaved weeds. It has a significant effect on the control of broad-leaved weeds such as pig scorp...
