1. The types of diseases and pests should be confirmed first, and then effective agents should be sprayed. It is important to remember that any pesticide is not a panacea and must be prescribed for the disease to have an effect.
2. Before using pesticides, read the instruction manual to follow the instructions and precautions, and find out if they can be mixed with each other.
3. The concentration of the drug is appropriate, and if it is too concentrated, it will cause phytotoxicity. If it is too thin, it will not produce an effect.
4. Use a measuring cylinder to measure the pesticide, the concentration is accurate, and stir evenly with the handle.
5. In order to prolong the effect of the drug, the pesticide can be permanently attached to the plant body or the pest, and the spreading agent should be mixed and sprayed.
6. Seedlings are susceptible to phytotoxicity, and seedlings that have just been replaced or planted must be sprayed after some time.
7. Different varieties, the situation of phytotoxicity is also different. It is best to select several strains for testing to determine if they will be tainted and then spray them thoroughly.
8. Avoid applying under high temperature sunshine to avoid phytotoxicity. It is better to choose in the morning or evening, and you should be careful not to spray against the wind. After the rain, the leaves must be dried before spraying.
9. Wear masks and gloves, long-sleeved shirts, and trousers when spraying. Wash hands and face thoroughly with soap.
10. Do not put the pesticide and food together. The storage place is preferably a lockable room or cabinet to prevent the child from eating.
1l. Unused liquid medicine, can not be dumped at will, empty bottles, empty bags, can not be arbitrarily discarded, so as to avoid danger and environmental pollution.
12. The combination of organic matter and pesticides in the soil often reduces the effect of pesticides, so soils with high organic matter should be applied at higher levels.
13. The structure of the soil also affects the amount of application. The fine soil, such as clay, has a large surface area and requires a large amount of application. Soil with coarse particles, such as sand, has a small surface area and can be applied less.
14. If it rains immediately after application, the pesticide will be washed away and must be re-applied once.
15. "The natural selection of the natural survival, the survival of the fittest." Pathogens or insect pests will also be resistant to pesticide toxicity, so it is not allowed to use the same or the same brand of pesticides for a long time.
16. After spraying pesticides, avoid touching the plants immediately to avoid contaminating the pesticides, especially the uninformed family members and children.
17. If you choose to spray without wind or breeze, if there is strong wind or strong wind when applying pesticides, you should stop spraying to prevent the pesticide from scattering around and causing injury.
18. When spraying, pets and unrelated personnel should be out of the area where they want to spray. Those who have fish ponds in the courtyard should also be prevented from spraying the medicine into the pool when spraying.
19. If you accidentally contaminate your hands, feet or any part of your body during spraying, you should rinse it immediately to avoid poisoning and rickets. It is better to use detergent or soapy water when cleaning.
20. Pesticides must be stored in a cool dry place, avoid direct sunlight, so as not to lose the efficacy.
