As the saying goes: Spring is a grain of millet, autumn harvests of 10,000 seeds, spring is a good time to plant crops, common crops such as eggplant, leeks, peppers, soybeans, etc. are suitable for sowing in the spring. The spraying of pesticides is a very important maintenance process during the planting of crops. Proper pesticide spraying management can not only reduce costs, but also improve crop survival rate. In the rural areas, many farmers only regularly spray pesticides in the field, and did not choose a specific application period. The resulting results page is often unsatisfactory. Today Xiaobian came to introduce you to a special period of spraying pesticides, hoping to help everyone solve this problem. First, the pests are in full bloom: In order to prevent the growth and spread of pests, the main purpose of spraying pesticides in order to prevent the occurrence of crop diseases is to prevent the growth and spread of pests. In general, the period of growth of pests can be divided into three stages: egg hatching period, larval stage and adult stage, but no matter which stage needs good grasp of pest habits, pesticide spraying can be carried out. The effect is maximized. For example, when treating cotton bollworm, it can be used at the peak of egg hatching, and its control effect is very obvious. If the larva is used at the peak of 2 to 3 years old, the control effect is very poor. To put it simply, knowing ourselves and knowing each other can not be arrogant, so the familiarity and understanding of the living habits of pests is the premise of pesticide spraying and maintenance work. Second, the sensitive period of natural enemies: The natural food chain is used to maintain the ecological Balance of the crops. For example, the natural enemies of the mites are cockroaches. Therefore, it is necessary to minimize the spraying of pesticides during the period when the cockroaches are sensitive to the medicinal agents. Third, the disease growth period: Regardless of which crop, it is the best time to spray pesticides in the growth stage where disease is easy to occur, and it can have a good preventive effect on the disease of crops, such as the most susceptible to blight during the seedling stage, before sowing. Seed dressing with fungicide or spray control at seedling stage. Fourth, weed sensitive period: When applying some pesticides such as herbicides, it is necessary to choose to use them during the sensitive period of weeds. In this period, the herbicidal effect is obvious, and the effect period is long. Usually, it is better to control the seedlings before sowing or the weeds 1 to 2 leaves. V. Crop safety period Crops are highly resistant during the safe period, and spraying pesticides at this stage can greatly reduce the phytotoxicity of pesticides on crops. Note: When spraying pesticides, be sure to pay attention to the safe use standards of pesticides. The spraying frequency should also be determined according to the actual growth of the crops. Choose a special period for rational application, so as not to cause adverse consequences.
