1. Recognize the scope and use of pesticides. Diseases and insect pests or associated weeds of each crop have their own special control agents, and the correct use of pesticides can increase crop yields and improve quality. However, misuse or excessive use will cause injury or delay the appropriate period of control, which will result in serious losses or residues, affecting the health of people and livestock. Therefore, in the use of pesticides should be studied in detail the scope of use and the correct use of each pesticide. 2. Recognize the toxicity of pesticides to avoid poisoning. Most pesticides have a strong toxicity, so when using pesticides to control pests and diseases, we must pay attention to the use of safety. For example, methamidophos, methyl iso-isocyanate, and iridfoam, should pay attention to its toxicity in use, must not be exposed to the liquid, in order to avoid the occurrence of poisoning. 3. Do not use pesticides indiscriminately. Crops after spraying should be harvested before the safe harvest period. Some of the pesticides are highly toxic or residual. If pesticides are not harvested after safe harvesting period, they will seriously affect human health. After the pesticide is used, its decomposition rate is different due to its chemical nature, and the slow decomposition rate is left on the crop for a long time. After eating, it will seriously affect the health of the body. Low-toxic or easily-decomposable pesticides such as Emamectin, Abamectin, Acetamiprid, Imidacloprid, Diflubenzuron, etc. should be used on vegetables or on harvested crops. It is safer to use on crops. 4. Do not use pesticides to increase the concentration or mix multiple pesticides at one time. A certain pesticide is used to control certain pests and diseases, and the concentration used is the result of field experiments. The average farmer often increases the concentration arbitrarily when formulating liquid medicines, reduces the multiple of water, and makes the sprayed liquid medicine concentration too high, which causes the crops to remain toxic during the safe harvesting period. In some cases, phytotoxicity may occur due to the increase in concentration. For example, when farmers use organic phosphorus pesticides, their concentrations are often increased to cause poisoning accidents. 5. Pesticides should be placed in places that are not easily accessible to children and must not be mixed with other items. Pesticides should never be placed in the hall, kitchen, or under the bed. It is best to use a special cabinet for locks and must not be stored near food. 6. If the application machinery fails, it should be repaired in time. The appliance used should be checked for water leakage, whether the spout is unimpeded or not, and whether the interface is sturdy so as to avoid malfunction in the operation, resulting in poisoning caused by contact with the liquid. 7. The field work should be properly rested, spray time is preferably not more than four hours per person per day, and do not spray for several consecutive days. It is best for minors, pregnant women, the elderly and people with weaker bodies not to serve as spraying. 8. When dispensing pesticides, do not touch the stock solution. Most pesticides penetrate the skin and come into contact with the skin. In particular, high concentrations of the stock solution, as long as it touches the skin in small amounts, is absorbed to cause poisoning. There are also some pesticides that are very volatile and can easily be inhaled by the trachea. Therefore, when deploying pesticides, gloves and masks should be worn and stirred with a stirring rod. Do not use hands instead. 9. The liquid should be rinsed immediately if it touches the skin carelessly. If you accidentally touch the liquid in the spray, wash it with soap quickly. If you get into the eyes, wash it immediately with salt water (9 servings of salt, 1000 servings of water). 10. Wear protective equipment when spraying pesticides in the field to avoid poisoning. 11. Spray pesticides should pay attention to the weather. On the spot of spraying, smoking is prohibited and the bathing is completed after spraying. The pesticide plot should be filled with humans and animals, pesticide packaging should be properly handled, and pesticide poisoning must be promptly rescued.
