The current winter season is the best time for weeding in post-emergence wheat fields. How to use wheat herbicides correctly is very important. There are many types of herbicides, and each herbicide has a certain herbicidal effect. Therefore, farmers can only receive the desired results if they use the wheat herbicide correctly. First, strict optimal application time. Many farmers choose the time to use herbicides in the wheat field in the spring, and wait until the grass age and density of the weeds are applied. Weed grass age at this time Large, drug resistance is enhanced, and the dose must be increased during the prevention and treatment, which increases the cost and is easy to cause phytotoxicity to wheat and sorghum and adjacent crops. The time is generally selected before the emergence of wheat, pre-emergence herbicides, or wheat 2-4 leaf stage selection of herbicides that can kill the weeds. Second, strictly control the temperature and humidity of the application. 1. Master the temperature at the time of application. The temperature of the application directly affects the effect of the herbicide. Therefore, the use of herbicides in wheat fields should be applied when the temperature is high on sunny days to fully exert the effects. 2. Ensure that the soil moisture is sufficient when applying the medicine. Whether it is the application of soil before the emergence of wheat or the application of wheat during the growing season, soil moisture is an important factor affecting the efficacy. When the seedlings are applied before the seedlings, if the soil moisture of the topsoil is large, it is easy to form a strict sealing layer of the soil, and the weed seeds are germinated and quickly released, so the control effect is high. When the wheat is applied in the growing season, if the soil is moist, it is beneficial to the weeds to absorb the herbicides and operate in the body, so the effect of the drug is fast and the herbicidal effect is good. Third, strictly control the amount of medication. Weeds and wheat are plants, and the selectivity of herbicides is limited. To ensure that herbicides kill both weeds and wheat, we must strictly control the amount of herbicides, neither increase nor decrease. The dosages described in the manual are used and adapted to local conditions. Fourth, strictly control the spraying technology. When using herbicides, be sure to dilute enough water and mix well. To achieve uniform spraying, no heavy spray, no leakage. If adjacent plots are sensitive crops of herbicides, isolation measures should be taken to prevent the crops of adjacent plots from being damaged if there is wind. It is best to use herbicide-spraying equipment to prevent crop damage when spraying other pesticides .
