Embodiment 1

[0020] Example 1: 60% bisacenil·bicyclic sulcotrione water-dispersible granules.

[0021] Dipyrazonil 35%, Bicyclic Sulfotrione 25%, Alkylphenol Ethoxylate 6%, Alkylphenol Ethoxylate Sulfate 5%, Ammonium Sulfate 2.5%, Polyethylene Glycol 2%, Kaolin Supplement 100%. Mix the above-mentioned active ingredients, wetting agent, dispersant, disintegrant, binder and solid carrier evenly, pulverize with an ultra-fine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation and drying , and sieve to obtain 60% dipacenil·bicyclic sulcotrione water-dispersible granules.

Embodiment 2

[0022] Example 2: 80% bisacenil·bicyclic sulcotrione water-dispersible granules.

[0023] Dipyrafenil 50%, bicyclic sulcotrione 30%, sodium lauryl sulfate 5%, glycerin fatty acid polyoxyethylene ether 5%, urea 3%, sodium polyacrylate 2%, and diatomaceous earth make up 100%. Mix the above-mentioned active ingredients, wetting agent, dispersant, disintegrant, binder and solid carrier evenly, pulverize with an ultra-fine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation and drying , and sieve to obtain 80% dipacenil·bicyclic sulcotrione water-dispersible granules.

Embodiment 3

[0024] Example 3: 50% dipacenil·bicyclic sulcotrione wettable powder.

[0025] Dipyramid 10%, bicyclic sulcotrione 40%, sodium butylnaphthalene sulfonate 15%, sodium methylene bis-naphthalene sulfonate 12%, and diatomaceous earth make up 100%. Mix the above-mentioned effective ingredients, wetting agent, dispersant and solid carrier, mechanically pulverize, then airflow pulverize, and mix uniformly to prepare 50% dipacenil·bicyclic sulcotrione wettable powder.

Abstract

The invention discloses a herbicide composition containing pyraclonil and benzobicylon. The herbicide composition comprises pesticide adjuvants, pyraclonil and benzobicylon, wherein the ratio of parts by weight of pyraclonil to benzobicylon is (10 to 1)-(1 to 15); the total weight of pyraclonil and benzobicylon is 0.1-85% of the weight of the herbicide composition. The herbicide composition is applicable to controlling annual weeds in paddy fields, has obvious synergistic or additive control effects compared with a single agent, reduces the dosages of pesticides, reduces the pesticide costs, prolongs the service lives of the pesticides and reduces the adverse effects of the pesticides on the ecological environment.

Description

technical field [0001] The invention relates to a pesticide herbicidal composition and its application field, in particular to a herbicidal composition with dipacenil and bicyclic sulcotrione as active ingredients, which is mainly used for the control of annual weeds in paddy fields. Background technique [0002] Pyraclonil: a new type of bispyrazole herbicide for paddy fields, the mechanism of action is an inhibitor of protoporphyrinogen oxidase, and it is a contact herbicide. It can effectively control all kinds of weeds, including barnyardgrass, special-shaped sedges, aquatic plants, sagittarius, yujiuhua, fluttering grass, wild water chestnuts, bermudagrass, etc., as well as weeds resistant to sulfonylurea herbicides. [0003] Bicyclic sulcotrione (benzobicylon): It is a post-emergent herbicide for albino rice fields of bicyclooctane, and an inhibitor of hydroxyphenylpyruvate dioxygenase. Its selectivity between rice and weeds is extremely high, and it is against annual...
