Embodiment 1

[0016] Embodiment 1: prepare the oil suspension concentrate of the compound herbicide of the present invention (sulfuron-methyl: florasulam=2: 1)

[0017] 6% disulfuron-methyl·flusulam oil suspension concentrate, 6% refers to the percentage of the two active components of disulfuron-methyl and florasulam in the total weight. Take 4kg methylsulfuron-methyl, 2kg florasulam, 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

[0018] Embodiment 2: Prepare the wettable powder of compound herbicide of the present invention (Mesulfuron-methyl: Flusulam=3:1)

[0019] 28% disulfuron-methyl · florasulam wettable powder, 28% refers to the percentage of the two active components of disulfuron-methyl and florasulam in the total weight. Take 21kg of disulfuron-methyl, 7kg of florasulam, 4kg of dispersant NNO, 3kg of wetting agent K12, 4kg of 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

[0020] Embodiment 3: Preparation of the water dispersible granule of compound herbicide of the present invention (Mesulfuron-methyl: Flusunacil=4: 1)

[0021] 50% Mesulfuron-methyl · Fluorasulam water-dispersible granules, 50% refers to the percentage of the two active components Mesulfuron-methyl and Fluorasulam in the total weight. Take 40kg of disulfuron-methyl, 10kg of florasulam, 7kg of D-425, 5kg of EFW, 5kg of ammonium sulfate, 2kg of polyethylene glycol, and kaolin to make up 100%, after thorough mixing, jet milling, mixing, granulation, and drying and sieve to obtain water-dispersible granules.

Abstract

The invention relates to the technical field of herbicides, and discloses a postemergence compound herbicide for wheat. The postemergence compound herbicide for wheat contains two types of active ingredients, namely, mesosulfuron-methyl and florasulam, wherein the weight ratio of the mesosulfuron-methyl to the florasulam is (2-4):1, and preferably, the weight percentage of the mesosulfuron-methyland the florasulam is 0.1-85% of the compound herbicide. The compound herbicide disclosed by the invention both can be used for preventing and killing off annual grass weeds and broadleaf weeds in wheat lands, and has a significant weeding effect, a remarkable synergistic effect, and no effect on after-reap crops, therefore, the compound herbicide 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...
