Wheat field weeding technical measures

June 17, 2023

To choose the herbicide. In wheat fields dominated by monocotyledonous weeds, herbicides such as thrips, horses, and horses can be used. In wheat fields dominated by dicotyledonous broad-leaved weeds, herbicides such as stutoxylon, thifensulfuron, 2,4-D-butyric, and the like may be used. For single and dicotyledon mixed wheat fields, superstars or tribenuron plus tamarind may be used in combination.

The best medication period. Chemical weeding in wheat fields in spring is completed from the beginning of returning to the beginning of jointing stage. Spraying is too early and the effect of low temperature is not good. Spraying too late will cause phytotoxicity to the wheat seedlings and will cause phytotoxicity to the crops.

To master the temperature and humidity when using drugs. The time required to start the medication requires the average daily temperature to be above 10°C and to be on a sunny day from 10am to 3pm. If the soil is dry, it must be poured back to the green water and then sprayed with herbicide.

To strictly control the dosage and the method of preparation. To strictly control the amount of medication, can not arbitrarily reduce or increase the dose, so as not to reduce the control effect or produce phytotoxicity. To prepare the liquid, use the secondary dilution method, first prepare the original drug into the mother liquor, add water to the sprayer, then pour the appropriate amount of mother liquor, and then add fresh water and mix well. Water consumption per mu is not less than 30 kg.

To master the correct use. Spraying should be even and thoughtful, as far as possible to make the agent moist weed stems and leaves, and do not re-spray, no leakage spray.
