Pesticides can only be used rationally to achieve safety, efficiency, and economy. Otherwise, it will not only fail to achieve the desired results, but may also cause adverse consequences. The following points should be made when using drugs: First, the right medicine. All kinds of pesticides have certain control targets. When preventing and treating certain diseases and weeds, we must prescribe the right medicine, that is, we cannot use insect remedies to treat diseases, nor can we use insecticides for treatment of diseases, and should be based on the characteristics of the agents and the rules of the occurrence of prevention and control objects. Choose safe, effective, and economical medicines. Do not use drugs blindly. Second, timely medication. It is very important to prevent and treat diseases and weeds when choosing the right period for use. Only when the appropriate period for prevention and control is determined, can the full effect of pesticides be brought into play, and medication must be taken before or immediately after the occurrence of diseases and weeds. Only by grasping key opportunities and timely prevention and control can we achieve good results. Third, the amount of medication. It is an important link to control pests and weeds to master the appropriate dosage. Too high dosage will not only cause waste, but also aggravate polluting environment and even cause crop damage and human and animal safety. If the amount is too low, the control effect will be affected and the resistance to insect pests will be induced. In the application should be in accordance with the recommended dose of various pesticides can not be arbitrarily increased or decreased. Fourth, accurate medication. All kinds of pesticides have a certain residual period, expired is invalid. The number of prevention and cure should be based on the residual period of pesticides and the occurrence of pests and diseases in order to receive good results. Do not spray on high winds, rain, fog, or high temperatures at noon. Spraying should be done before 10 o'clock in the morning and after 4 o'clock in the afternoon. After spraying, it rains. After the rain, it is necessary to make up the spray. The spraying should be uniform, the fog should not be too large, the spray is meticulous and thoughtful, so that the plants and leaves are full of drugs on both sides, and the spraying is not heavy enough to ensure the quality of application. Fifth, rotation medication. A single long-term continuous use of a single pesticide, easy to produce drug resistance, especially some pyrethroid insecticides, systemic fungicide, continuous use control effect will be greatly reduced. Rotating the use of pharmacological mechanisms with different pesticides is an effective method for delaying the development of insecticide resistance. Six, mixed medication. The rational compounding of mixed pesticides can improve the control effect, expand the control objects, delay drug resistance, save labor and time, and give full play to the role of pesticide formulations. Although there is a great advantage in pesticide compounding, it must not be combined arbitrarily because some pesticides can be mixed and some cannot be mixed. Before use, we must fully understand the nature of pesticides and the possibility of mixing pesticides. For pesticides that cannot be mixed, use them separately. After each spraying, clean the sprayer. Salmon Pet Food,Salmon Pet Snacks,Freeze Dried Petfood,Freeze Dried Salmon Pet Food Ningbo Nutrition Food Technology Co.,ltd. , https://www.collagenworkshop.com
