First, pay attention to the choice of the dosage form of the agent. The agent should be selected to be able to melt into water. The dosage form is a wettable powder, a liquid, an emulsion and a suspension. Soaking powders can not be used, because the powders are insoluble in water but sinking or floating on the water, seed dip medicine unevenness, seed soaking reach sterilization effect.
Second, the concentration of the drug solution should be accurate. The concentration of the drug used for soaking seeds is generally calculated according to the effective ingredient content of the drug. Soaking agent concentration and soaking time is generally related to the concentration of low Soaking time can be slightly longer, high concentration of soaking time should be shorter, if you do not master the exact concentration, it is easy to reduce the occurrence of injury or seed soaking effect.
Third, master the soaking time The pesticide soaking has a certain time requirement, too long will produce phytotoxicity, too short to achieve the purpose of disinfection. DETAILED soaking time to operate in accordance with instructions of drugs.
4. Seeds after soaking should be rinsed and aired. Seeds with poor tolerance to the drug should be rinsed with water as required after immersion to avoid phytotoxicity. If not specified after dipping to wash, you do not have to be washed. Regardless of need or do not need washing, after dipping should be spread out to dry, and some can be sown directly after the dip should be in accordance with the type of pesticide and soil moisture may be.
Fifth, the liquid level should be higher than the seed. When soaking seeds, the liquid should be higher than the seeds by more than 16 cm, so as to prevent the seeds from swelling and exposing the liquid surface to reduce the soaking effect.
6. Stirring thoroughly The seeds should be thoroughly stirred in the liquid medicine to eliminate the air bubbles of the liquid medicine, so that the seeds and the liquid medicine can be fully contacted to improve the soaking effect.
