Weeds affect wheat production. Farmers often choose herbicides and weeds. However, if the science of spraying is not scientific, it will not only cause weeding but also cause damage to wheat and after-crop crops. Plant protection expert Kang Kegong reminds us to do science well from the following aspects: Medication. Accurate selection of herbicides For wheat fields dominated by gramineous weeds such as Bromegrass and Fritillaria, Shima Spray can be used for control. It is best to use Dubang Superstars and Hummer to control the use of weeds such as sow plant and leeks. The wheat fields mixed with broad-leaved weeds and grass weeds can be uniformly sprayed with Duoma Superstars, Wheatgrass, etc., and evenly sprayed. Choose the best medication time The use of herbicides in the spring increases both the cost and the risk of phytotoxicity to wheat and postharvest and adjacent crops. Therefore, it is necessary to spray before the emergence of wheat or wheat in the 2nd to 4th leaf stage, and to select herbicides that can kill the emerged weeds. Grasp the appropriate temperature and humidity The use of herbicides above the average temperature of 6°C in sunny days will yield very good results. It is generally advisable to use sunny days from 10am to 3pm. The efficacy of most herbicides requires a certain degree of soil moisture, and if the soil is moist, it will be beneficial to herbicide efficacy. Severe drought, herbicides should be used in combination with watering (or after rainfall) at an opportune time and in time. Accurately master the amount of medication When dispensing medicine, it is necessary to accurately measure the area of ​​pesticide application. The size of the medication should be determined according to the time of application, temperature, lyrics, seedling age, and soil conditions. When the soil is dry, the amount of water should be increased, and weeds with large seedling age should increase the dose. In addition, many drugs to prepare the mother liquor, that is, a small amount of water in a small container to dissolve the agent, to be fully dissolved before adding the sprayer. Improve drug application technology When applying, the mother liquor should be uniformly added into the sprayer that has been filled with half a bucket of water and mixed evenly before applying. If crops on adjacent plots are sensitive to herbicides, isolation measures should be taken to avoid crop damage. It is best to use pesticides for spraying herbicides so as not to injure crops when spraying other pesticides.
