Pesticide soaking has a significant effect on the future pest control of seeds, but pesticide soaking must be scientific. The following six points must be noted:
First, pay attention to the choice of dosage form
The selected agent must be soluble in water. Can not be soaked with powder, because the powder is insoluble in water, the powder floats on the surface or sinks, the seeds are not evenly spread, and the effect of soaking and sterilizing is not achieved.
Second, accurate dispensing of pharmaceutical liquid
The concentration of the agent used for soaking seeds is not calculated based on the weight of the seed, and is generally calculated based on the active ingredient content of the agent. The concentration of the soaking agent is generally related to the soaking time. When the concentration is low, the soaking time can be slightly longer. When the concentration is high, the soaking time should be shortened. If the concentration is not accurately grasped, it is easy to cause phytotoxicity or reduce the soaking effect.
Third, fully stirred
The seeds should be thoroughly stirred in the liquid to eliminate the bubbles in the liquid, so that the seeds are in full contact with the liquid, and the soaking effect is enhanced.
Fourth, the liquid level should be higher than the seed
When soaking seeds, the liquid level should be 16 cm or more higher than the seeds, so as to prevent the seeds from absorbing water and exposing the liquid surface to reduce the effect.
5. Master the soaking time
If the time is too long, it will cause phytotoxicity. If it is too short, it will not achieve the purpose of disinfection. The specific soaking time should be based on the instructions for use of the drug.
6. Pay attention to whether the soaked seeds need to be rinsed and aired.
Seeds with poor tolerance to the drug should be rinsed with water as required to avoid phytotoxicity. If you do not specify the water wash after dipping, you do not need to wash it. Whether it needs or does not need to be washed, it should be spread out after drying. However, some can also be directly sown after soaking, depending on the type of pesticide and soil moisture.
