Prevention and control of crop pests, pesticide soaking is the most effective way, then what should be paid attention to pesticide soaking? Let's follow the Xiaobian to understand it.
1. Pesticides should be easily soluble in water
The pesticide selected for the appropriate pesticide dosage form must be easily soluble in water, and should not be soaked with powder pesticides that are insoluble in water or poorly soluble in water. Because the pesticides that are insoluble in water or poorly soluble in water are mostly suspended in the water or sink, the seeds are not contaminated or the drug is uneven.
2, control the soaking time
The soaking time should be suitable for the soaking of the pesticide for a certain period of time. If the time is too long, it will cause phytotoxicity, and the time is too short to achieve the purpose of disinfection. Therefore, the specific soaking time should be determined according to the characteristics of the seed variety, the instructions for use of the drug, and the temperature of soaking.
2, completely soak
Mastering the method of soaking seeds After the seeds are immersed in the liquid medicine, it is necessary to fully stir to discharge the air bubbles in the liquid medicine, so that the seeds are in full contact with the liquid medicine, thereby improving the seed soaking effect. Moreover, the level of the solution of the soaked seed solution should be 12-15 cm higher than the seed, so as to prevent the seed from absorbing water and exposing the liquid surface, thereby reducing the soaking effect.
4. After soaking, the seeds should be dried.
After soaking, the seeds should be cleaned in time and air-dried. The seeds should be rinsed with water in time to avoid phytotoxicity. If it is not required to be washed after soaking, it is not necessary to wash it. Whether or not you need to wash, you should spread the soaked seeds to the air.
