Abstract

The invention provides a cyhalofop-butyl-containing weed oil suspension composition, which comprises the following components: 1 to 15 percent of cyhalofop-butyl, 10 to 30 percent of quinclorac, 1 to 10 percent of emulsifying agent, 2 to 8 percent of wetting dispersing agent, 0.1 to 5 percent of suspension stabilizer, 0 to 5 percent of antifreezing agent, 0 to 0.2 percent of organosilicon defoaming agent and the balance of vegetable oil. The cyhalofop-butyl-containing weed oil suspension composition has the obvious synergistic effect, and the prevention and control effect on weed caper euphorbia seed in a paddy field, such as cockspur grass and the like, is superior to that of a single-dose medicament of the cyhalofop-buty and the quinclorac. The weed oil suspension composition improves the prevention and control effect, enlarges weed control spectra, retards weed resistance and reduces application amount and application cost, and is safe for crops.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to an oil suspension composition of cyhalofop-ethyl and quinclorac. Background technique [0002] Cyhalofop-ethyl is an aryloxyphenoxypropionic acid herbicide, which is mainly used to control barnyardgrass, stephenia and other gramineous weeds in rice fields, and is highly safe to rice. [0003] Quinclorac is a hormone-type quinoline carboxylic acid herbicide, which is mainly used to control barnyardgrass in rice fields. It has a long application period and is safe for rice. [0004] The cost of quinclorac is low, and it has high activity and good control effect on barnyardgrass in paddy fields, but it has poor control effect on Echinochloa chinensis. The price of cyhalofop-ethyl is relatively high, but it has special effect on rice field daughter. The combination of cyhalofop-ethyl and quinclorac oil suspension has obvious synergistic effect, which can not only significantly improve the...
