1. In the 3-6 leaf stage of winter wheat before winter, the annual grass weeds 2.5-5 leaf stage, the sooner the better the medicine is used after the weeds are out, the water consumption is 15-30 liters/mu, and the stems and leaves are evenly sprayed. Wheat should not be applied after it has been lifted.
2. For the medicine, first pour the priority and auxiliary into the small pot and add a small amount of water to stir evenly. Then pour the liquid in the small pot into the sprayer of half a bucket of water, then fill the sprayer with water and stir evenly. use.
3. When adding the pharmaceutical liquid, it is necessary to add auxiliaries at the same time. The dosage of the auxiliary agent is 15-150 ml/mu (equivalent to 0.1-0.5% of the spray volume).
4. Strictly apply according to the recommended dosage, period and method. Spray should be sprayed at a constant speed and evenly to avoid heavy spray, leak spray or over-range application.
5, should not be applied before the bad weather such as frost low temperature (minimum temperature below 2 °C), it is not suitable to apply this agent in wheat fields suffering from phlegm, freezing, salt damage, disease and malnutrition, not enough water within 2 days before and after application Diffuse the wheat field to avoid phytotoxicity.
6. After application, the wheat seedlings sometimes have temporary yellowing or seedling phenomenon. Under normal use conditions, the yellowing disappears after the wheat is greened, and generally does not affect the yield.
7. Weeds stop growing after application, generally die after 2-4 weeks; weeds die slowly at drought and low temperature; rainfall does not significantly affect the efficacy after 1 hour of application.
8. Clean the used medicines to avoid phytotoxicity of residual pesticides on other crops.
9. When there is dew on the surface of wheat leaves, delay the use to prevent loss.
