Pesticide soaking seeds plays a major role in the prevention and control of future pests and diseases of the seeds, but pesticide soaking must be scientific. The following six points must be noted: First, pay attention to the choice of pharmaceutical formulations selected drugs must be dissolved in water. Can not be soaked with powder, because the powder is insoluble in water, powder floating on the surface of the water or sinking, uneven drug seed, can not achieve the effect of soaking sterilization. Second, the exact concentration of chemicals used in the preparation of liquid soaking agents is not calculated based on the weight of the seed, generally calculated according to the effective content of the pharmaceutical ingredients. The soaking agent concentration is generally related to the soaking time. When the concentration is low, the soaking time may be slightly longer. When the concentration is high, the soaking time should be shortened. If the concentration is not accurately grasped, the phytotoxicity is likely to occur or the soaking effect is reduced. Third, fully stir the seeds into the liquid to be fully stirred to eliminate the bubbles in the liquid, so that the seeds and the liquid full contact, improve the soaking effect. Fourth, the liquid surface to be higher than the seeds in the soaking, the liquid surface to be higher than the seeds more than 16 cm, so as not to increase the liquid surface exposed after swelling, reduce the effect. Fifth, mastering the soaking time for a long time will cause harm to the medicine. Too short will not achieve the purpose of disinfection. Specific soaking time should be based on instructions for use of the drug. 6. Pay attention to whether the seeds that are soaked need to be washed and dried. After soaking the seeds that have poor tolerance to the chemicals, they should be washed with clean water as required to avoid phytotoxicity. If you do not specify how to wash after dipping, you do not need to wash. Whether it needs to be washed or not, it should generally be dried after soaking. However, some can also directly sow after soaking, which depends on the type of pesticide and soil moisture conditions.
