Embodiment 1

[0038] Weigh 3% glufosinate-ammonium, 9% fluorfen, 15% propargyl flufen, 6% sorbitan monostearate, 5% fatty acid polyoxyethylene ester, 1% polyvinyl alcohol, 0.5% ethylene glycol, 2% penetrant JFC, 0.5% sodium benzoate, deionized water to make up the balance. Dissolve fluorflufen propargyl in cyclohexanone, add sorbitan monostearate and stir to form an oil phase; mix deionized water and other additives with a high-speed shear homogenizer, and then add ethyl carboxylate The technical product of acifluorfen is sand-milled in a sand mill, so that the particle size D90 of the suspension is below 5 μm. Add the oil phase and glufosinate-ammonium technical crystals into the sand-milled suspending agent, and under high-speed shearing, make the particle size D90 of the drug solution below 5 μm, and you can make 27% glufosinate-ammonium fluorfen · Suspoemulsion of flufenazol propargyl.

Embodiment 2

[0040] Weigh 10% glufosinate-ammonium, 30% fluorfen, 10% propargyl flufen, 11% sorbitan monostearate, 5% sodium polycarboxylate, 1.3% magnesium aluminum silicate, 0.4 % Potassium Sorbate, soybean oil makes up the balance. Mix soybean oil and other additives evenly with 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 suspension is below 5 μm, and then 50% glufosinate-ammonium can be made ·Acetoxyfluorfen ·Propyroxyfen dispersible oil suspension concentrate.

Embodiment 3

[0042] Weigh 3% glufosinate-ammonium, 30% fluorfen-ethanol, 3% fluorfen-propargyl, 5% alkylphenol polyoxyethylene ether phosphate, 6% sodium lauryl sulfate, 3% ammonium sulfate , 4% sodium carboxymethyl cellulose, white carbon black make up the balance. Mix the above raw materials evenly, pulverize and mix evenly with an ultra-fine jet mill, add water to knead and granulate, dry and sieve in a boiling dryer, and after testing and analysis, you can make 36% glufosinate-ammonium ethyl carboxyfluoride Fenoxet·flurafen propargyl water dispersible granules.

Abstract

The invention relates to a special weeding composition for citrus orchards and non-cultivated lands, the weeding composition at least comprises glufosinate-ammonium, fluoroglycofen-ethyl and flumioxazin, and the mass ratio of the active components is (1-50): (1-50): (1-50), preferably (1-10): (1-10): (1-10). The weeding composition can be prepared into preparation formulations including an aqueoussolution, a suspending agent, a suspoemulsion, a dispersible oil suspending agent, wettable powder, water dispersible granules, granules and a microcapsule suspension-suspending agent according to amethod known by technicians in the technical field. The weight percentage of the active ingredients in the preparation is 1%-80%, preferably 5%-75%. The invention also relates to an application of thecomposition in preventing and removing weeds in citrus orchards and non-cultivated areas.

Description

technical field [0001] The invention relates to a herbicidal composition, which is composed of active ingredients glufosinate-ammonium, fluorfen-ethanol and flumechlor-propargyl, and belongs to the technical field of compounding pesticide compounding. Background technique [0002] Flumioxazin propargyl, English common name flumioxazin, chemical name: 7-fluoro-6-(3,4,5,6-tetrahydro)phthalimide-4-(2-propynyl)-1 ,4-Benzoxazin-3(2H)-one is a cyclic imine herbicide in structure. Flurafen propargyl is a herbicide absorbed by young shoots and leaves. It can effectively control annual broad-leaved weeds and some grass weeds when used as soil treatment. It is easy to degrade in the environment and is safe for subsequent crops. Soybeans and peanuts have good resistance to it. Corn, wheat, barley, rice are moderately tolerant. [0003] Fluorofluorfen, English common name Fluoroglycofen, chemical name: 0-[5-(2-chloro-a,a,a-trifluoro-p-tolyloxy)-2-nitrobenzoyl]glycolic acid Ethyl est...
