(R)-Quizalofop Ethyl 5% EC is a high-speed and selective dry field stem and leaf treatment agent. It has a high selectivity between gramineous weeds and dicotyledonous crops. It is less affected by environmental conditions such as rain, temperature and humidity. It has a good control effect on gramineous weeds in soybean field. The mechanism of action is that through the absorption of weed stems and leaves, it conducts upward and downward in the plant, accumulates in the apical and intermediate meristem, inhibits the synthesis of cellular fatty acids, and makes the weed necrosis. Quizalofop Ethyl is mainly used to control annual and perennial gramineous weeds of broad-leaved crops, such as barnyardgrass, Dogtail grass, wild oats, arm grass, tendon grass, bromegrass, Qianjin, autumn grass, thrush grass, bermudagrass, reed, creeping ice grass, etc. it is not effective for broad-leaved weeds. Quizalofop Ethyl is an arylphenoxypropionic acid herbicide with selectivity, internal absorption and conduction, stem and leaf treatment and low toxicity. As a selective post bud herbicide, the leaves absorb and conduct, accumulate at the top, destroy the internode meristem, lose the regeneration ability, stop growth and wither. There is a high selectivity between gramineous weeds and dicotyledonous crops. The stems and leaves can complete the absorption of chemicals in a few hours and move to the upper and lower parts of the plant. The medicament can spread all over the plant within 24 hours to make the annual weed necrotic. After the annual weed is treated, the new leaves turn yellow and stop growing in 2-3 days, the stems and leaves become bad and dead in 4-7 days, and the whole plant withers and dies in 10 days. After the perennial weed is treated, the drug is rapidly transmitted to the underground rhizome tissue, making it lose its regeneration ability.
Quizalofop Ethyl is mainly used in soybean, cotton, peanut, sugar beet, tomato, cabbage, grape and other crop fields to control annual and perennial gramineous weeds such as barnyardgrass, horse Tang, beef tendon grass, kanmai Niang, Dogtail grass, wild oats, bermudagrass, reed and white grass. The annual grass weeds were eliminated. When weeds were 3 to 6 pieces of leaves, 40 to 60 ml of 5% EC was applied to each acre. Spray treatment was carried out on the water of 40 to 50 kg of water. In order to control perennial grasses, weeds of 4-6 leaves per plant were treated with 5% EC to 130 ml – 200 milliliters per mu and 40 to 50 kg of water were sprayed with stem and leaf.
Quizalofop Ethyl 5% (EC) is widely used to control gramineous weeds in various broad-leaved crop fields. The action speed is fast and the efficacy is stable. Add additives imported from Germany to enhance permeability, rain erosion resistance and evaporation resistance. It is safe for the environment and does not affect the next crop.
