Embodiment 1

[0020] Embodiment 1: prepare the oil suspension concentrate (thifensulfuron-methyl:clodinafop-propargyl=1:2) of compound herbicide of the present invention

[0021] 12% thifensulfuron-clodinafop-propargyl oil suspension concentrate, 12% refers to the percentage of the two active components of thifensulfuron-methyl and clodinafop-propargyl in the total weight. Take 4kg flufenacet-thifensulfuron-methyl, 8kg clodinafop-propargyl, 8kg Pluronic125, 5kg propylene glycol, 0.5kg xanthan gum, 1kg methylated vegetable oil, and make up to 100kg with water. The oil suspension is obtained through full mixing and preparation, ball milling, adjustment and packaging.

Embodiment 2

[0022] Embodiment 2: prepare the wettable powder (thifensulfuron-methyl:clodinafop-propargyl=1:1) of compound herbicide of the present invention

[0023] 50% thifensulfuron-clodinafop-propargyl wettable powder, 50% refers to the percentage of the two active components of thifensulfuron-methyl and clodinafop-propargyl in the total weight. Take 25kg thifensulfuron-methyl, 25kg clodinafop-propargyl, 4kg dispersant NNO, 3kg wetting agent K12, 4kg white carbon black, and light calcium carbonate to make up to 100kg. Wettable powder is obtained through thorough mixing, jet milling and mixing.

Embodiment 3

[0024] Embodiment 3: prepare the water dispersible granule (thifensulfuron-methyl:clodinafop-propargyl=1:3) of compound herbicide of the present invention

[0025] 60% thifensulfuron-clodinafop-propargyl water-dispersible granule, 60% refers to the percentage of the two active components of thifensulfuron-methyl and clodinafop-propargyl in the total weight. Take 15kg of thifensulfuron-methyl, 45kg of clodinafop-propargyl, 7kg of D-425, 5kg of EFW, 5kg of ammonium sulfate, 2kg of polyethylene glycol, and kaolin to make up 100%. After fully mixing, jet milling, mixing, granulating, drying and sieving Water-dispersible granules were obtained.

Abstract

The invention relates to the technical field of pesticides and discloses a composite herbicide used after wheat seedling emergence. The composite herbicide used after wheat seedling emergence comprises two active components of thifensulfuron methyl and clodinafop-propargyl, wherein a weight ratio of thifensulfuron methyl to clodinafop-propargyl is 1: (1 to 4), and preferably, the composite herbicide used after wheat seedling emergence comprises 5 to 85% by mass of thifensulfuron methyl and clodinafop-propargyl. The composite herbicide used after wheat seedling emergence can eliminate annual broad leaf weeds of the wheat land and prevent and eliminate gramineous weeds of the wheat land, has obvious weed removal effects and obvious synergistic effects, and does not influence after-cultured crops. Therefore, the composite herbicide used after wheat seedling emergence is an ideal herbicide.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a post-emergence compound herbicide for wheat. Background technique [0002] Wheat is one of the main food crops in northern my country, and it is also an important feed crop. The annual planting area in my country is more than 30 million hectares, second only to the rice planting area. The area of ​​wheat field weed damage accounts for more than 30% of the total planting area, of which more than 8% are severely damaged, and the yield is generally reduced by more than 15%, and in severe cases, the harvest may be completely eliminated. Therefore, the proportion of herbicides used in domestic wheat fields is almost 100%, and the dosage is very large. At present, the main herbicides for post-emergence control of weeds in domestic wheat fields are: pyroxaprop-ethyl, methylsulfuron-methyl, flucarbasulfuron-methyl, tribenuron-methyl, fluroxypyr, dicamba, metsulfuron-methyl , thias...
