In the process of crop planting, in order to achieve high yield, it is necessary to do insecticide and weeding work. No matter which kind, it is inseparable from herbicides, so herbicides are indispensable in agricultural production. The use of herbicides is related to the type of weeds. In the process of spraying, it is also affected by the environment. What should you pay attention to? Let's take a look at it. When is the herbicide sprayed better? Under normal circumstances, the best spraying time of the herbicide should be before the 10:00 am on the sunny day or after 4 pm, and the full day time on a cloudy day (not raining), during which time the herbicide can be fully utilized. effect. Spraying notes: 1. If there is dew in the morning, try to spray as much as possible. Because the pesticide will be diluted by dew, it will not achieve the desired effect, and it may also slide down to the ground with dew and will not affect weeds. 2. For high temperature and high temperature, do not spray pesticides at noon. First, because the plants will close the pores due to a large amount of water loss at high temperatures, the herbicides will not enter the weeds, which will greatly reduce the herbicides. The efficacy of the drug. Second, if the water of the liquid evaporates, the concentration of the pesticide will increase, and phytotoxicity may occur. 3, high temperature weather is best to fight after 4 o'clock in the afternoon, although the temperature is relatively low before 10 o'clock in the morning, but want the herbicide to maximize the effectiveness, the time of spraying should be correct and reasonable, if the temperature rises at noon, spray The herbicidal effect is good, but it may also be accompanied by phytotoxicity. In addition to being affected by temperature, herbicides are subject to other external conditions, such as high winds, which can cause herbicides to fly and float, especially in helicopters. Rain and snow weather will reduce the efficacy of herbicides, etc., so pay close attention to weather conditions before spraying. The above is the point of use of herbicides, crop planting, want to effectively remove weeds to ensure high yield, understanding these knowledge points will help more or less.
