Embodiment 1

[0022]A swimming and diffusing type bensulfuron-methyl herbicide on the water surface of paddy fields, which consists of the active ingredients of pesticides, bensulfuron-methyl, pendimethalin, a water surface extender, a disintegrant, a polymer dispersant, a binding agent, a wetting agent, Adsorbent, core material with a specific gravity smaller than water, etc., wherein the weight percentage of each component in the composition is: Bensulfuron-methyl 10%, Pendimethalin 15%, Water surface expander 20%, Disintegrant 10% %, 10% of adsorbent, 5% of wetting agent, 10% of binder, 10% of polymer dispersant, 10% of core material carrier whose specific gravity is less than water, and the effective ingredients of the pesticides are bensulfuron-methyl, dimethyl Wuling is a rice field herbicide with sealing effect. The carrier has a specific gravity smaller than water and a particle size of 40-120 microns, which can make the agent float on the water surface like a "boat". The carrier has...

Abstract

Water surface swimming diffuse type bensulfuron methyl herbicide for a rice field is prepared from, by weight, 10-20% of bensulfuron methyl, 20-40% of pendimethalin, 15-40% of a water surface spreading agent, 5-10% of a disintegrating agent, 5-15% of polymeric dispersant, 5-15% of binder, 5-15% of a wetting agent, 10-30% of adsorbent and 10-30% of a core material with the specific gravity smaller than that of water. A user can directly put the swimming diffuse herbicide to the water surface without going to the field during herbicide application, water soluble bags can be dissolved within 2-3 min after being put, herbicide particles are dissociated immediately, fast disintegrated in a radial shape and randomly float and expand in all the directions, the herbicide particles are continuously disintegrated from big to small, the active components are fast and uniformly dispersed to the whole water surface, a herbicide film is formed on the water surface, the whole water layer becomes suspension liquid of the herbicide, and the herbicide effect is brought into full play.

Description

Technical field: [0001] The invention relates to a rice herbicide, in particular to a novel rice herbicide. Background technique: [0002] Rice is an important grain and economic crop in my country, with a wide planting area, and occupies a pivotal position in the daily life of the people. According to incomplete statistics, in 2015, the national rice planting area reached 450 million mu, and the total annual rice output was 204 million tons. According to the forecast of relevant parties, the domestic rice shortage will continue to expand. Vigorously develop rice production and maintain the basic position of domestic rice in production and living needs. This is not only an objective requirement to give full play to the advantages of my country as a major rice producer, but also an inevitable choice to maintain my country's self-sufficiency in major grains. The commodity rate of rice is affected by many factors such as planting conditions and management measures. The main s...
