Most pesticides are toxic chemicals. Pesticides can enter the body to destroy normal physiological functions and cause poisoning, causing severe death. Therefore, the use of pesticides must pay attention to safety, which should arouse people's great attention. For this reason, operators must wear rubber gloves, caps, and masks to prevent the liquid or powder from sticking to the skin during dispensing and spraying. Do not apply on hot afternoons. When spraying or dusting, it is best to choose a day without wind. If there is a breeze, spray it in the downwind direction to avoid splashing liquid or powder onto the face or inhaling toxic gas. Do not drink, eat or smoke while spraying. Wash hands with soap immediately after application. The empty drug bottle used for medicinal purposes should be destroyed immediately and it should not be used as a utensil. Equipment that has been used with pesticides should be soaked in alkaline water for more than one day and then rinsed with fresh water.
While paying attention to personal safety, we must also pay attention to the safety of flowers. The main factors causing the occurrence of phytotoxicity of flowers are: improper use of the chemical species or improper use period, or excessive doses, uneven spraying, and certain unfavorable natural conditions. Some pesticides have different sensitivities to different varieties of the same flower, some varieties are safe, some varieties are prone to phytotoxicity. Different development stages of the same species also have different responses to pesticides. Before using a pesticide, the above points must be understood and mastered. It is easy to produce phytotoxicity at high temperature and strong sunshine at noon. Therefore, summer application should be carried out in the evening. In general, flowering seedlings, young shoots, and young leaves are susceptible to phytotoxicity. Most flowers are sensitive to pesticides during flowering, so they should be used with caution.
Precautions for custody of pesticides: 1 The drug must be stored in a cool, dry and ventilated place. The label on the package must be intact to avoid misuse and ingestion. 2 Pesticides should not be put together with food, and they should not be placed in the living room. 3 Liquid pesticides should be protected from freezing during the cold season. Powder should be protected against moisture. All pesticides should not be placed in direct sunlight. 4 All kinds of flammable pesticides such as emulsifiable concentrates, oils, fumigants, etc. should be kept away from the fire source.
