Problems solved by technology

[0004] The effect of cyhalofop-methyl on the control of the old daughter and crabgrass is unsatisfactory, while fenoxaprop-ethyl has special effects on the control of the old daughter and crabgrass, but it is easy to cause phytotoxicity when the dosage is slightly large, and its safety needs improvement

Abstract

The invention provides a weeding oil suspension agent, which contains 1 to 30 percent of cyhalofop-butyl, 1 to 20 percent of fenoxaprop-p-ethyl, 1 to 10 percent of emulsifier, 2 to 8 percent of wetting dispersant, 0.1 to 5 percent of suspension stabilizer, 0 to 0.2 percent of organic silicon defoamer and the balance of vegetable oil. The weeding oil suspension agent has obvious synergistic effect, and has excellent prevention and control effect on rice field weeds such as gramineous weeds of caper euphorbia seed, cockspur grass and the like, particularly older caper euphorbia seed and digitaria sanguinalis. The weeding oil suspension agent composition can improve the prevention and control effect, expand a weeding spectrum, delay weed resistance, reduce phytotoxicity generated when the consumption of the fenoxaprop-p-ethyl is high, and is safe for crops.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a herbicide oil suspension containing cyhalofop-ethyl. 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] Fenoxaprop-ethyl is a heteroepoxyphenoxypropionic acid herbicide, suitable for controlling dicotyledonous crops such as soybean, peanut, rape, cotton, sugar beet, flax, potato, vegetable field and mulberry orchard. Leaf weeds can also be used to control annual grass weeds such as barnyardgrass and stephenia in paddy fields. [0004] The effect of cyhalofop-methyl on the control of the old daughter and crabgrass is unsatisfactory, while fenoxaprop-ethyl has special effects on the control of the old daughter and crabgrass, but it is easy to cause phytotoxicity when the dosage is slightly large, and its safety...
