Embodiment 1

[0025] Embodiment 1: 24% ethoxysulfuron-clopyrazosulfuron-methyl oil suspension concentrate

[0026] The components of the pesticide composition containing ethoxysulfuron-methyl and clopyrazosulfuron-methyl are: ethoxysulfuron-methyl 8%, clopyrazosulfuron-methyl 16%, phenethylphenol polyoxyethylene ether 5%, lignosulfuron 8% Sodium Oleate, 5% Epoxidized Soybean Oil, 5% Organic Bentonite, 100% Methyl Oleate.

[0027] After adsorbing and mixing ethoxysulfuron-methyl and the filler, add the other above-mentioned materials (except organic bentonite) into the reaction kettle mixer together, stir evenly, and inject the materials into the multi-stage sand mill for grinding. The fineness of the ground materials is 98% pass through 1-5um and discharge. The material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, it can be made into 30% ethoxysulfuron-chlorpyrazosulfuron oil suspension concentrate .

Embodiment 2

[0028] Embodiment 2: 16% ethoxysulfuron-clopyrazosulfuron suspension concentrate

[0029] The components of the pesticide composition containing ethoxysulfuron-methyl and clopyrazosulfuron-methyl are: ethoxysulfuron-methyl 6%, clopyrazosulfuron-methyl 10%, phenethylphenol polyoxyethylene ether 5%, lignosulfuron Sodium phosphate 8%, ethylene glycol 5%, magnesium aluminum silicate 2%, defoamer 0.5%, preservative 0.1%, xanthan gum 0.1%, water to 100%.

[0030] After adsorbing and mixing ethoxysulfuron-methyl and the filler, add other above-mentioned materials (except xanthan gum) into the reactor mixer together, stir evenly, inject the materials into the multi-stage sand mill for grinding, and the ground materials are fine The material is discharged after passing through 1-5um with a density of 98%. The material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. After emulsification, it can be made into 48% ethoxysulfuron-methyl-clopyrazos...

Embodiment 3

[0031] Example 3: 20% ethoxysulfuron-clopyrazosulfuron wettable powder

[0032] The components of the pesticide composition containing ethoxysulfuron-methyl and clopyrazosulfuron-methyl are: ethoxysulfuron-methyl 6%, clopyrazosulfuron-methyl 14%, sodium lauryl sulfate 2%, butylnaphthalenesulfonic acid Sodium 3%, Calcium Lignosulfonate 5%, Silica 5%, Kaolin to 100%.

[0033] After adsorbing and mixing the ethoxysulfuron filler, put it into the conical mixer together with the other above-mentioned materials and mix evenly, and then pulverize it through the jet mill, and then mix the pulverized material through the conical mixer. The fineness of the mixed material is 98 % Pass through a 325-mesh standard sieve to obtain 50% ethoxysulfuron-methyl-clopyrazosulfuron wettable powder.

Abstract

The invention discloses a pesticide composition comprising ethoxysulfuron and halosulfuron-methyl and application thereof, the pesticide composition comprises the active components of the ethoxysulfuron and the halosulfuron-methyl, and the mass ratio of ethoxysulfuron to halosulfuron-methyl is 0.05-10: 0.5-10. The pesticide composition, showing obvious synergistic effect on the matching range, reduces the pesticide dosage, reduces the pesticide dosing number, reduces the pesticide dosing cost, reduces the adverse effects of pesticides on ecological environment, expands the herbicidal spectrum, can solve various weed problems by one-time use, makes up the defects and limitations when using a single agent, extends the agent service life, has the vital significance to the comprehensive treatment of weed resistance, is fast in drug efficacy, long in period of preserving effect and low in use cost, and can be used to control broadleaf weeds and sedge weeds in rice fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing ethoxysulfuron-methyl and clopyrazosulfuron-methyl for controlling broad-leaved weeds and Cyperaceae weeds in paddy fields. Background technique [0002] According to statistics, the world's grain production loses 14% every year due to diseases, insects, and weeds, and the loss caused by weeds is about 11%. Weed damage is a key factor restricting crop production. The use of chemical herbicides is one of the important symbols of modern agriculture. In recent years, sales of herbicides have increased year by year, accounting for an increasing proportion of pesticide sales, and the application area has expanded year by year. Rice is the crop with the largest consumption, the largest planting area, the largest total output and the highest per unit yield in China, and it has an important position in the world. However, the serious oc...
