How to use quizalofop herbicide?

What is the weeding principle of quizalofop herbicide? How to use quizalofop herbicide? Netizens with knowledge are also asked to help introduce that there are 5%, 8%, 8.8%, 10%, 10.8% and 15% quizalofop EC herbicides in the current agricultural market, but many netizens do not understand the herbicidal principle and scope of application of the herbicide, so the farming network has sorted out the principle and application of the herbicide, which is listed in detail below for netizens' reference. The herbicidal principle of quizalofop: quizalofop is an improved low toxic herbicide after the inactive optical isomers are removed in the process of synthesizing herbicides. The principle is absorbed by the stems and leaves of weeds, conducts upward and downward in the plant, accumulates in the apical and intermediate meristem, inhibits cellular fatty acid synthesis, and causes weed necrosis. Quizalofop is a new type of highly selective stem and leaf treatment agent in dry field, which has a high selectivity between Gramineae weeds and dicotyledonous crops, and has a good control effect on Gramineae weeds in broad-leaved crop fields. The action speed of quizalofop is faster and the efficacy is more stable, so it is not easy to be affected by Rain Water's temperature and humidity and other environmental conditions. Moreover, under the condition that the efficacy of quizalofop is not reduced, the dosage is reduced, and the protection of the environment is safer. Quizalofop is suitable for soybean, beet, rape, potato, flax, pea, broad bean, tobacco, watermelon, apple, grape, cotton, peanut, broadleaf vegetable and other crops. The weeds that can be effectively controlled by quercefop are: wild oat, barnyard grass, dogtail grass, golden dogtail grass, horse tang, wild millet, sagittaria, brome, barley, Italian ryegrass, poisonous wheat, millet, Kentucky bluegrass, double-ear paspalum, Bermudagrass, white grass, creeping ice grass, Reed and other annual and perennial grasses. The usage of quizalofop herbicide: 1. Soybean field: when annual Gramineae weeds grow to three leaves, spray weed stems and leaves with 50 ml of 5% quizalofop EC 50 ml mixed with water per mu. 2. Watermelon field: when annual Gramineae weeds grow to about three to five leaves, spray weed stems and leaves with 5% quizalofop EC 40ml 60ml mixed with water per mu. 3. Rape field: when annual Gramineae weeds grow to three-leaf stage, spray weed stems and leaves with 50 ml / mu of quizalofop EC 50ml / mu mixed with water. Notes on the use of quizalofop herbicide: 1. 0.75-1.0 liter per hectare is used to control Setaria viridis and wild millet. The dosage should be adjusted with the weed leaf age, the weed leaf age should be lower, and the weed leaf age should be increased. 2. The mixture of quizalofop and prednisone can reduce the paspalum-killing effect of quinofop, and can not be mixed with trifluorocarboxylic ether and imidazole nicotinic acid. 3. After quizalofop was applied on the weed leaves, the weed plants yellowed and stopped growing within 2 days. 5 to 7 days after application, the young leaves and primary tissues on the nodes withered, and the weeds withered completely about 14 days. 4. 5% quizalofop EC can be used up to once in annual grasses such as cotton, peanuts, rape, soybeans and so on.
