Mastering soaking time for pesticide soaking has a certain time requirement. If the time is too long, it is easy to produce phytotoxicity. Especially in high temperature season, soaking time should be adjusted according to the variety characteristics. If the seeds are thick and hard seeds, the time should be appropriate to allow the drug to penetrate the seed coat and kill the internal bacteria.
Pay attention to the selection of pharmaceutical agents. Agents used for soaking are diluted reagents. The reagents used must be soluble in water. Note that powder soaking cannot be used because the powder is insoluble in water, the powder floats on the water surface or sinks, and the seeds are not evenly coated, which does not achieve the effect of soaking and sterilizing.
The concentration of the agent used to accurately prepare the solution for soaking is not calculated based on the weight of the seed, and is generally calculated based on the content of the effective component of the agent. 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 is shortened. If the concentration is not accurately grasped, it is prone to phytotoxicity or to reduce the soaking effect.
Keep in mind that after rinsing, the seeds that are poorly tolerant to the medicament after rinsing and drying 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. Regardless of the need or need of washing, general soaking should be followed by drying, but some can also be sowed directly after soaking, depending on the type of pesticide and soil moisture conditions.
