Embodiment 1

[0067] First, 102g of butachlor with a purity of 98%, 10g of penoxsulam with a purity of 99%, 5g of pyrazosulfuron-methyl with a purity of 98%, 20g of silicon dioxide, 10g of surfactant alkylphenol polyoxyethylene ether, and sorbitan Monolaurate 10g, food-grade preservative sodium benzoate 20g, pH regulator sodium carbonate 1g and filler sepiolite 22g are mixed uniformly and then subjected to superfine pulverization to obtain granulated mother powder; then the prepared mother powder, After mixing 300g of the environment-friendly oily substance methyl oleate and 500g of perlite evenly, extruding, granulating and drying, the floating large granule for paddy field closed weeding is prepared.

Embodiment 2

[0069] First, 102g of butachlor with a purity of 98%, 51g of penoxsulam with a purity of 99%, 5g of pyrazosulfuron-methyl with a purity of 98%, 20g of silicon dioxide, 15g of surfactant fatty acid polyoxyethylene ester phosphate, lignosulfonic acid Sodium 15g, food-grade preservative sodium benzoate 20g, pH regulator light calcium carbonate 1g and filler diatomaceous earth 21g are evenly mixed and then subjected to superfine pulverization to obtain granulated mother powder; then the prepared mother powder, environmental protection After 50 g of epoxy soybean oil and 700 g of perlite are uniformly mixed, extruded, granulated, and dried, the paddy field closed weeding and floating large granule agent is obtained.

Embodiment 3

[0071] First, 306g of butachlor with a purity of 98%, 30g of penoxsulam with a purity of 99%, 51g of pyrazosulfuron-methyl with a purity of 98%, 100g of silicon dioxide, 60g of surfactant fatty acid polyoxyethylene ester phosphate, dodecyl 70g of calcium benzenesulfonate, 20g of food-grade preservative sodium benzoate, 1g of pH regulator sodium carbonate and 12g of filler sepiolite are mixed uniformly and then subjected to ultrafine pulverization to obtain granulated mother powder; then the prepared mother powder, After 50g of turpentine-based vegetable oil and 300g of perlite are uniformly mixed, the environment-friendly oily substance is extruded, granulated, and dried to obtain a large floating granule for paddy field sealing and weeding.

Abstract

The invention relates to the technical field of pesticide, in particular to a herbicidal composition and large-scale blocking herbicidal floating granules in paddy fields. The herbicidal composition comprises, by weight, 1-100 parts of butachlor, 1-10 parts of penoxsulam and 1-10 parts of pyrazosulfuron. The herbicidal composition has a significantly synergistic effect after the combination of butachlor, penoxsulam, and pyrazosulfuron, and can effectively control main weeds in paddy fields (such as monochoria vaginalis, barnyard grass, and crabgrass). By the compounding of butachlor, penoxsulam, and pyrazosulfuron, the large-scale herbicide used in paddy fields has the advantages of being cost-effective, broadening the herbicidal spectrum, enhancing herbicidal efficiency and having an obvious blocking effect. The large-scale herbicidal floating granules in paddy fields can be sprayed directly by men, save time and effort, be convenient and quick to use, and safe for the men spraying the herbicide.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicidal composition and a paddy field closed weeding and floating large granule. Background technique [0002] Rice is not only the most important food crop in my country, but also one of the main food crops in the world. Nearly half of the world's population, including almost all of East and Southeast Asia, eat rice. Production is on every continent except Antarctica. In the late last century, the average annual rice output in the world was about 400 billion kilograms, and the planting area was about 145 million hectares. The sown area of ​​rice in my country accounts for 1 / 4 of the national grain crops, about 35 million hectares per year, while the output accounts for more than half. Regardless of planting area and output, rice ranks first among my country's food crops. [0003] And the paddy fields of all rice-growing regions in my country have always had a large a...
