Abstract
The present invention belongs to the technical field of pesticides and discloses a weeding composition containing pyribenzoxim, pretilachlor and ethoxysulfuron. The weeding composition comprises main effective components: the pyribenzoxim, the pretilachlor and the ethoxysulfuron in a mass ratio of (0.1-10):(5-75):(0.1-10); the total sum of the pyribenzoxim, the pretilachlor and the ethoxysulfuron accounts for 10-80% of the weeding composition in mass. The present invention also discloses wettable powder, water dispersible granules, a suspending agent, emulsion in water and missible oil, which are prepared from the weeding composition and used for preventing and weeding gramineous weeds, broadleaf weeds and cyperus weeds. The weeding composition disclosed by the present invention has the characteristics of being small in resistance risk, low in prevention and treatment cost, wide in weeding range, good in efficacy, excellent in efficacy lasting, and slight in environmental pollution.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to a mixed herbicidal composition comprising three active ingredients of saflufenacil, pretilachlor and ethoxysulfuron-methyl, and an application of the mixed herbicidal composition. Background technique [0002] Rice is one of the main food crops with the largest planting area in my country. Although various control methods such as artificial and chemical agents have been adopted, about 50% of the paddy fields are still damaged to varying degrees every year. Among them, paddy field weeds have a great impact on rice yield, and there are many types of paddy field weeds, such as barnyardgrass, stephenia, bermudagrass, knotweed, cow felt, dwarf arrowhead, eye vegetable, clover, Among water amaranth, water sedge, sagittarius, and special-shaped sedge, barnyardgrass has the widest distribution and damage area, followed by special-shaped sedge, bermudagrass, daughter of a daughter, and ...
