Problems solved by technology

[0005] Residue problems caused by long-term use of herbicides commonly used in cotton fields on the market (such as oxaprop-ethyl, imazethapyr, clethodim, nicosulfuron, bentazone, etc., or their mixed preparations) It has become an important safety hazard affecting the growth of subsequent crops
At the same time, as some of the above-mentioned herbicide varieties are used alone on a large scale, many weeds have developed resistance, resulting in a decline in the effect of herbicides

Embodiment 1

[0038] Weigh 20% fenmetrione, 5% pendimethalin, 5% flumechlor propargyl, 5% sodium dodecylbenzene sulfonate, 4% sodium lignosulfonate, 3% ethylene glycol, 1% xanthan gum, 0.5% hexanol, 0.4% sodium benzoate, and deionized water to make up the balance. Mix deionized water and other additives evenly with a high-speed shear homogenizer, then add the active ingredients and grind them in a sand mill, so that the particle size D90 of the suspending agent is below 5 μm, and then it can be made into 30% Promethazone, pendimethalin, and flurafen propargine suspension concentrate.

Embodiment 2

[0040] Weigh 12% fenmetrione, 2.4% pendimethalin, 24% flumechlor propargyl, 5% castor oil polyoxyethylene ether, 6% glycerin fatty acid ester polyoxyethylene ether, 0.8% carboxyethyl Cellulose, 2.5% trisiloxane, cotton oil make up the balance. Mix cotton oil and other additives evenly through a high-speed shearing homogenizer, then add active ingredients, and perform sand grinding in a sand mill, so that the particle size D90 of the suspending agent is below 5 μm, and then 38.4% benzodiazepine can be prepared Ketone · pendimethalin · propargyl fluorine dispersible oil suspension concentrate.

Embodiment 3

[0042] Weigh 3% fenmetrione, 12% pendimethalin, 12% flumechlor propargyl, 7% alkylphenol polyoxyethylene ether phosphate, 6% pull open powder BX, 3% ammonium sulfate, 4% sodium carboxymethylcellulose, attapulgite to make up the balance. Mix the above raw materials evenly, pulverize and mix evenly with an ultra-fine airflow mill, add water to knead and granulate, dry and sieve in a boiling dryer, and after testing and analysis, you can make 27% methacridone dimethyl Pentolerin·flurafen propargyl water dispersible granules.

Abstract

The invention relates to a weeding composition safe to cotton and afterreap crops. The weeding composition is reasonable in formula and low in use cost, and has a synergistic control effect on a certain target. The weeding composition at least comprises three active components including metamitron, pendimethalin and flumioxazin in a mass ratio of (1-100): (1-100): (1-100), preferably (1-10): (1-10): (1-10). The weeding composition can be made into preparation forms including a suspending agent, a suspoemulsion, a dispersible oil suspending agent, wettable powder, a water dispersible granule, agranule and a microcapsule suspension-suspending agent according to a method known by technicians in the art, and the weight percentage content of the active components in the preparation is 1%-80%,preferably 5%-70%. The composition is used for preventing and removing weeds in cotton fields.

Description

technical field [0001] The invention relates to a herbicidal composition, which is composed of active ingredients memetrazone, pendimethalin and flumechlor propargyl, and belongs to the technical field of compounding pesticide compounding. Background technique [0002] Promethazinone, English common name metamitron, chemical name: 3-methyl-4-amino-6-phenyl-4,5-dihydro-1,2,4-triazin-5-one), structurally It is a triqinone compound, and its mechanism of action is a photosynthesis inhibitor. It is mainly used for the control of gramineous weeds and broad-leaved weeds in sugar beet fields such as nightshade, chickweed, bluegrass, chrysanthemum, and pig's weed. [0003] Pendimethalin, English common name pendimethalin, chemical name: N-(1-ethylpropyl)-2,6-dinitro-3,4-dimethylaniline, belongs to aniline herbicide in structure, In terms of mechanism of action, it is an inhibitor of meristem cell division. It does not affect the germination of weed seeds, and works after the young...
