Embodiment 1

[0036] Flurafen propargyl 1%, pendimethalin 20%, promethazine 20%, calcium dodecylbenzene sulfonate 8%, sodium lignosulfonate 7%, fatty alcohol polyoxyethylene ether 3%, white Carbon black 8%, kaolin the balance. Mix all the ingredients evenly according to the above ratio, and make the average particle size of the material less than 5um through jet milling. A 41% propargylflurafen, pendimethalin, and promethonin wettable powder (1:20:20) can be obtained.

Embodiment 2

[0038] Flurafen propargyl 1.5%, pendimethalin 20%, promethazine 15%, calcium dodecylbenzene sulfonate 8%, sodium lignosulfonate 7%, fatty alcohol polyoxyethylene ether 3%, white Carbon black 8%, kaolin the balance. Mix all the ingredients evenly according to the above ratio, and make the average particle size of the material less than 5um through jet milling. A 36.5% propargyl fluoride, pendimethalin, and promethonin wettable powder (3:40:30) can be obtained.

Embodiment 3

[0040] Flurafen propargyl 0.5%, pendimethalin 15%, promethazine 10%, calcium dodecylbenzenesulfonate 6%, castor oil polyoxyethylene ether 5%, polyoxyethylene polyoxypropylene block copolymer 3% organic silicon defoamer, 0.1% organic silicon defoamer, 3% organic bentonite, and 100% soybean oil. The above-mentioned ingredients are mixed evenly according to the stated ratio, and the average particle size of the obtained material is less than 5 microns after being ground by a horizontal sand mill.

Abstract

The invention discloses a weeding composition. The weeding composition comprises the following effective components: flumioxazin, pendimethalin and prometryn, the weight ratio of the flumioxazin, thependimethalin and the prometryn in the weeding composition is (1-3): (20-40): (20-40), and the total weight percentage of the flumioxazin, the pendimethalin and the prometryn in the weeding composition is 1%-80%. By the weeding composition, a herbicide controlling spectrum can be expanded remarkably, overall prevention and removal effects to weeds in cotton fields are achieved, and meanwhile, thecomposition is good in safety to cottons, and is an excellent novel pesticide combination which prevents and removes annual weeds of cotton fields.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemistry, and in particular relates to a herbicidal composition. Background technique [0002] Flumioxazin belongs to cyclic imide herbicides, which can be absorbed by the young shoots and leaves of plants, conduct conduction in plants, inhibit the synthesis of chlorophyll, and cause rapid withering, albinism, necrosis and death of sensitive weeds . Flurafen propargyl has the effect on Polygonum japonica, Polygonum sorrel leaf, Polygonum japonicus, Piechu, Weasel petal flower, Nightshade nightshade, Amaranthus retrovertica, Abutilon, Chenopodium chinense, Chenopodium chinense, Cyperus chinensis, Acanthopanax coxanthum, sorrel genus, shepherd's purse, curly blue cabbage, commelina, etc. have good control effects. It has a certain inhibitory effect on annual gramineous barnyardgrass, foxtail, golden foxtail, wild oats and perennial lettuce. [0003] The chemical name of pendimethalin is N-(...
