Embodiment 1

[0020] Formulation example 1: 55% haclopyrid-metazone-methylsulfuron-methyl water-dispersible granules.

[0021] Fluclopyridate 10%, Methazone 30%, Mesosulfuron 15%, Sodium Lauryl Sulfate 5%, Methylenebis-Naphthalene Sulfonate Sodium Formaldehyde Condensate 5%, p-Methoxy Fatty Amide Base benzene sulfonic acid 5%, sodium hexametaphosphate 3%, hydroxyethyl cellulose 0.5%, silicone oil 0.1%, anhydrous calcium chloride 0.1%, diatomaceous earth supplement 100%. Mix the above active ingredients, wetting agent, dispersant, disintegrant, binder, defoamer, stabilizer and solid carrier evenly, pulverize with ultra-fine jet mill, knead, and then add fluidized bed to granulate and dry Granulating, drying and sieving in the machine can be used to prepare 55% fluorine chloropyridine-mefluxazone-methylsulfuron-methyl water-dispersible granules.

Embodiment 2

[0022] Formulation example 2: 60% of haclopyridoxazone-metasulfuron-methylsulfuron-methyl water-dispersible granules.

[0023] Fluclopyrid 10%, Methazone 30%, Mesosulfuron 20%, Sodium Lauryl Sulfate 5%, Dibutylnaphthalenesulfonic Acid Formaldehyde Condensate 5%, p-Methoxy Fatty Amidobenzenesulfonic Acid 5%, sodium hexametaphosphate 3%, polyvinyl acetate 0.5%, capric acid 0.1%, epichlorohydrin 0.1%, and diatomaceous earth make up 100%. Mix the above active ingredients, wetting agent, dispersant, disintegrant, binder, defoamer, stabilizer and solid carrier evenly, pulverize with ultra-fine jet mill, knead, and then add fluidized bed to granulate and dry Granulating, drying, and sieving in the machine can produce 60% halfluxafil-metrazone-methylsulfuron-methyl water-dispersible granules.

Embodiment 3

[0024] Formulation example 3: 80% haclopyrid-metazone-methylsulfuron wettable powder.

[0025] Fluclopyrid 20%, Methazone 40%, Mesosulfuron 20%, Dioctyl Sulfosuccinate Sodium 3%, Modified Alkyl Sulfonate 5%, Sodium Methyl Naphthalene Sulfonate Formaldehyde condensate 5%, attapulgite make up 100%. Mix the above active ingredients, wetting agent, dispersant and solid carrier, mechanically pulverize, then airflow pulverize, and mix uniformly to prepare 80% fluclopyrid-metafluxazone-methylsulfuron-methyl wettable powder.

Abstract

The invention relates to a weeding composition containing halauxifen-methyl, carfentrazone-ethyl and mesosulfuron-methyl. Effective ingredients of the weeding composition consist of halauxifen-methyl, carfentrazone-ethyl and mesosulfuron-methyl, wherein the part-by-weight ratio of halauxifen-methyl to carfentrazone-ethyl to mesosulfuron-methyl is (1-10): (1-20): (1-10). The weeding composition disclosed by the invention has a remarkable synergistic effect, the wheat-paddock annual weed preventing and weeding effects are obviously superior to those obtained when each single preparation is used independently, the weed control spectrum is enlarged, meanwhile, the consumption of pesticides is reduced, the generation of drug resistance of weeds is delayed, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a herbicidal composition containing halfenpyrid, mefentrazone and mesosulfuron-methyl, which is used for preventing and controlling wheat field Annual weed. Background technique [0002] At present, chemical control is still the most important means in the comprehensive management of farmland weed damage. However, long-term continuous high-dose application of a single chemical herbicide is likely to cause environmental pollution, phytotoxicity to crops, and weeds are prone to resistance. At the same time, due to the complex grass phase and various types of weeds in the field, such as grass weeds, broad-leaved weeds and other weeds, the use of a single species can no longer effectively solve this problem, and it will show a certain aspect. Defects. Reasonable compounding of chemical herbicides has many advantages such as expanding the herbicide spectrum, improving the control effect, prolonging the application period, reducin...
