Embodiment 1

[0022] Example 1: 70% pyriflumexime-oxaziclozone-pyrazosulfuron-methyl water-dispersible granule.

[0023] Pyrimifluben 15%, oxazicone 15%, pyrazosulfuron-methyl 40%, sodium dodecylbenzene sulfonate 5%, sodium methylene bis-naphthalene sulfonate formaldehyde condensate 5%, bentonite 3%, Hydroxypropyl Cellulose 2%, Attapulgite 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 70% pyrimiflubac-oxaziclodione-pyrazosulfuron-methyl water-dispersible granules.

Embodiment 2

[0024] Example 2: 50% pyriflumexime-oxacitrione-promethazone-methyl water-dispersible granule.

[0025] Pyrimifluzide 10%, oxazicone 15%, promethazone-methyl 25%, alkylnaphthalene sulfonate 5%, sodium polyacrylate 10%, bentonite 3%, hydroxypropyl cellulose 2%, concave-convex Stick clay makes 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 50% pyrimiflubac-oxacitrione-promasulfuron-methyl water-dispersible granules.

Embodiment 3

[0026] Example 3: 80% wettable powder of pyriflumechlor-oxaziculone-pyrazosulfuron-methyl.

[0027] Pyrimifluzide 15%, Oxazimidone 10%, Pyrazosulfuron-methyl 55%, Calcium Dodecyl Benzene Sulfonate 10%, Alkylphenol Polyoxyethylene Ether Formaldehyde Condensate 5%, Light Calcium Carbonate 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 80% pyriflumexime-oxaziclodione-pyrazosulfuron-methyl wettable powder.

Abstract

The invention discloses pesticide composition containing pyriminobac-methyl, oxaziclomefone and sulfonylurea herbicide. A mass ratio of pyriminobac-methyl to oxaziclomefone to the sulfonylurea herbicide is (1-20): (1-30): (1-50); the sulfonylurea herbicide is selected from one of metazosulfuron or propyrisulfuron. The pesticide composition is applicable to control of weeds in paddy fields; compared with single dose or binary combination use, the pesticide composition improves the weeding effect remarkably and expands the weed control spectrum, meanwhile, the usage amount of pesticide is reduced, the environmental pollution is reduced, the weed resistance is delayed, and the service life of the pesticide is prolonged.

Description

technical field [0001] The invention relates to a pesticide composition and its application field, in particular to a pesticide composition containing pyrimiflubac, oxazone and sulfonylurea herbicides as active ingredients, which is mainly used for controlling weeds in paddy fields. Background technique [0002] Pyriminobac-methyl: belongs to pyrimidine salicylic acid herbicides, it can be absorbed through the stems, leaves and roots of weeds, and quickly spread to the whole plant, inhibiting the biosynthesis of acetolactate synthase and amino acids, thereby inhibiting And hinder the cell division in weeds, stop the growth of weeds, and eventually make the weeds turn white and die; it has special effects on barnyardgrass in paddy fields, and is extremely safe for rice. [0003] Oxaziclomefone: a new type of herbicide belonging to the oxazinone class, with a unique mechanism of action. It is mainly used in paddy fields to control barnyardgrass, chickweed, daughter, and sedge,...
