Embodiment 1

[0020] Example 1: 70% fluazosulfuron-methylsulfuron-methyl water dispersible granules

[0021] Fluzosulfuron 60%, thiosulfuron 10%, sodium lauryl sulfate 5%, fatty acid ester sulfate 5%, sodium chloride 2%, kaolin supplements 100%. Mix the above-mentioned active ingredients, dispersant, wetting agent, disintegrant and solid carrier uniformly, pulverize with an ultrafine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation, drying, and sieving. 70% fluazosulfuron·methionsulfuron-methyl water dispersible granules can be prepared.

Embodiment 2

[0022] Example 2: 80% fluazosulfuron-methylsulfuron-methyl wettable powder

[0023] Fluzosulfuron 75%, Methiosulfuron 5%, Butyl naphthalene sulfonate sodium 5%, Alkylphenol polyoxyethylene ether formaldehyde condensate 3%, diatomaceous earth makes up 100%. The above-mentioned active ingredient, dispersant, wetting agent and solid carrier are mixed, mechanically pulverized, and then pulverized by air flow, and mixed uniformly, to obtain 80% fluazosulfuron-methylsulfuron-methyl wettable powder.

Embodiment 3

[0024] Example 3: 30% fluzosulfuron-methylsulfuron-methyl oil suspension

[0025] Fluzosulfuron 28%, Methiosulfuron 2%, Alkylphenol polyoxyethylene ether sulfate 10%, Sodium dodecylbenzene sulfonate 10%, Xanthan gum 0.5%, Methyl oleate makes up 100 %. After the above-mentioned active ingredients and additives are dispersed by high-speed shearing and sanded in a sand mill, a highly dispersed and stable suspension system is formed in a non-aqueous medium to obtain 30% fluazosulfuron·methylthiopyrim Sulfuron-methyl oil suspension agent.

Abstract

The invention relates to a weeding composition containing flucarbazone-sodium and methiopyrisulfuron. The effective components comprise flucarbazone-sodium and methiopyrisulfuron in a weight ratio of 40:1-1:1. The weeding composition has synergic actions on grassy weeds and broadleaf weeds in wheat fields, has obviously better weeding effects than a single agent, has wider weed control spectrum, lowers the pesticide consumption, reduces the environmental pollution and postpones the generation of drug resistance of weeds.

Description

Technical field [0001] The invention relates to a pesticide herbicidal composition and its application field, in particular to a herbicidal composition with fluazosulfuron-methyl and thiosulfuron-methyl as effective ingredients, which is applied to gramineous weeds and broadleaf weeds in wheat fields Prevention and treatment. Background technique [0002] Fluzosulfuron is a sulfonylurea systemic high-efficiency wheat field herbicide. It has obvious control effect on grass weeds such as wild oats, brome, and sylvestris and some broad-leaved weeds. Its active ingredients can be absorbed by the roots, stems and leaves of weeds. By inhibiting the activity of acetolactate synthase in the weeds, destroying the normal physiological and biochemical metabolism of weeds, it exerts herbicidal activity. It can be quickly metabolized in the body of wheat, and it is effective for Has excellent safety. [0003] Methiosulfuron-methyl is a highly effective herbicide obtained by structural modific...
