Embodiment 1

[0020] Example 1: 70% dipacenil·pretilachlor water-dispersible granules.

[0021] Bisacenil 10%, pretilachlor 60%, sodium lauryl sulfate 5%, alkylphenol polyoxyethylene ether sulfate 5%, ammonium sulfate 2%, 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 sieving to obtain 70% dipacenil·pretilachlor water-dispersible granules.

Embodiment 2

[0022] Example 2: 80% dipacenil·pretilachlor water-dispersible granules.

[0023] Dipyrafenil 5%, pretilachlor 75%, sodium lauryl sulfate 5%, naphthalenesulfonate formaldehyde condensate 5%, urea 2%, polyethylene glycol 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 sieving to obtain 80% dipacenil·pretilachlor water-dispersible granules.

Embodiment 3

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

[0025] 5% pyrenazole, 45% pretilachlor, 10% sodium butyl naphthalene sulfonate, 10% alkylphenol polyoxyethylene ether, diatomaceous earth to make up 100%. The above-mentioned active ingredients, wetting agent, dispersant and solid carrier are mixed, mechanically pulverized and then air-flow pulverized, and mixed uniformly to prepare 50% dipacenil-pretilachlor wettable powder.

Abstract

The invention discloses a herbicide composition containing pyraclonil and pretilachlor. The herbicide composition comprises pesticide adjuvants, pyraclonil and pretilachlor, wherein the ratio of parts by weight of pyraclonil to pretilachlor is (1 to 1)-(1 to 70); the total weight of pyraclonil and pretilachlor 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 pretilachlor as active ingredients, which is mainly used for the control of annual weeds in paddy fields. Background technique [0002] Difenpyril belongs to a new type of bispyrazole herbicide for paddy fields, its 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] Pretilachlor belongs to the amide herbicides, and its mechanism of action is a cell division inhibitor. It is suitable for controlling barnyardgrass, bald barnyardgrass, daughter, goosegrass, cow felt, Alisma narrow-leaf, water amaranth, special...
