Embodiment 1

[0020] Example 1: 70% bisacenil·tetramide·oxaprop-ethyl-ethyl water-dispersible granules.

[0021] Mesfenpyr 10%, Metrafen 50%, Fenoxaprop-P-P-10%, Sodium Butyl Naphthalene Sulfonate 5%, Alkylphenol Polyoxyethylene Ether Phosphate 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 sieve to obtain 70% bisfenpyr-tetrazen-oxaprop-ethyl water-dispersible granules.

Embodiment 2

[0022] Example 2: 80% bisfenpyr-tetrazen-oxaprop-ethyl water-dispersible granules.

[0023] Difenpyr 5%, Metrafen 70%, Fenoxaprop-P-P 5%, Sodium Lauryl Sulfate 5%, Fatty Alcohol Ethylene Oxide Additive Sulfate 5%, Urea 2% , polyethylene glycol 2%, 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% bispyraxenil·tetramide·fenoxaprop-ethyl water-dispersible granules.

Embodiment 3

[0024] Example 3: 50% bisacenil·tetramide·oxaprop-p-ethyl wettable powder.

[0025] 5% pyrenazole, 40% tetramethylene, 5% pyroxaprop-ethyl, 10% sodium dodecylbenzenesulfonate, 10% alkylphenol polyoxyethylene ether, diatomaceous earth supplement 100% %. Mix the above active ingredients, wetting agent, dispersant and solid carrier, mechanically pulverize and then pulverize by airflow, mix evenly, and then you can get 50% difenpyr-pyramid-tetramide-oxaprop-p-ethyl Wet powder.

Abstract

The invention relates to a weeding composition containing pyraclonil, fentrazamide and fenoxaprop-p-ethyl. Effective components comprise pyraclonil, fentrazamide and fenoxaprop-p-ethyl and the weight ratio of pyraclonil to fentrazamide to fenoxaprop-p-ethyl is (1-30) to (5-80) to (1-30). The weeding composition has the synergistic interaction effect and is mainly applied to prevention and treatment of annual weeds in paddy fields; compared with a single dosage or a binary compound, the weeding effect is obviously improved and the weeding spectrum is enlarged; and meanwhile, the pesticide use amount is reduced, the pollution to the environment is alleviated, and the generation of weed drug resistance is delayed.

Description

technical field [0001] The present invention relates to pesticide herbicidal composition and its application field, specifically a kind of herbicidal composition with bisfenpyr, tetramifen and fenoxaprop-p-p-ethyl as active ingredients. 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] Fentrazamide: a new type of herbicide belonging to the carbamoyl tetrazolinone class, and its mechanism of action is a cell division inhibitor. It has excellent control effect on gramineous weeds and sedge weeds in paddy fields, but the herbicide is onl...
