The selection of suitable dosage forms for pharmaceutical soaking is an effective measure for controlling pests and diseases and seedling stage diseases and insect pests. Grasping the technical essentials helps to increase the effectiveness of insecticidal sterilization. The drug used must be soluble in water, and powders that are insoluble in water should not be used because powders often float on the surface of the water or sink. The seeds are not evenly immersed and the soaking effect is poor. The concentration of the agent used to accurately formulate the seed soak is determined according to the seed weight. It is generally calculated according to the content of the active ingredient of the pharmaceutical agent or the amount of the preparation. Master the soaking method soaking the liquid to be higher than the seeds more than 16 cm, so as not to expose the liquid surface of the seeds after water swelling, reducing the soaking effect. After the seeds are put into the liquid medicine, they must be fully stirred, and the air bubbles in the liquid medicine should be eliminated, so that the seeds and the liquid medicine can be fully contacted and the soaking effect can be improved. Mastering soaking time for pesticide soaking has certain time requirements. If the time is too long, it is easy to produce phytotoxicity. If it is too short, it will not achieve the purpose of disinfection. The specific time will depend on the instructions for use of the drug. Seeds with poor tolerance to chemicals must be rinsed with water after soaking so as to avoid phytotoxicity. No specific instructions are to be made after immersion in water. Regardless of whether it is washed or not, it should generally be dried after soaking, but some plants can be sowed directly after soaking, depending on the type of pesticide and soil moisture.
