For the prevention and control of pests and diseases, pesticide soaking plays an important role in the seed, but the premise is that the pesticide soaking must be scientific. Today, the Chinese pesticide net Xiaobian said that there are some precautions for pesticide soaking .
First, mastering the time of soaking seeds, pesticide soaking has a certain time requirement. If the time is too long, it is easy to produce phytotoxicity, especially in the high temperature season; the soaking time should be adjusted according to the characteristics of the variety. If the seed coat is thick, the hard seed time should be longer, so that the agent has a period of time to penetrate the seed coat and kill the internal bacteria.
Second, pay attention to the choice of dosage form of the drug. The drug is soaked with a dilution of the drug, and the agent used 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.
3. The concentration of the agent used for the accurate soaking of the pharmaceutical liquid is not calculated based on the weight of the seed, and is generally calculated according to 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.
Fourth, the liquid level should be higher than the seed
When soaking seeds, the liquid should be 16 cm or more higher than the seeds, so as to prevent the seeds from swelling and exposing the liquid to reduce the soaking effect.
5. Stir the seeds thoroughly into the liquid to be fully stirred to eliminate the bubbles in the liquid, so that the seeds are in full contact with the liquid and improve the soaking effect.
6. The soaked seeds should be washed 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 dipping, but some can be directly sown after soaking, depending on the type of pesticide and soil moisture.
Finally, the Chinese pesticide network Xiaobian warm reminder: in the pesticide soaking, must be correctly operated according to the above methods, has reached the standard of pest control.
