Six details of pesticide dressing can not be ignored

Pesticide soaking has a significant effect on the future pest control of seeds, but pesticide soaking must be scientific, pay attention to the following six points:

Prevention and control of underground pests, pesticide soaking is a very effective way, pesticide soaking operations are relatively simple, but also need to pay attention to scientific methods, the following will follow the small series to understand.

One is to pay attention to the dosage form of the selected agent. The drug is soaked in a dilute of the drug, and the agent used must be dissolved 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 purpose of soaking seeds is not achieved.

The second is to accurately match the 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.

The third is to master the time of soaking. There is a certain time requirement for soaking seeds. 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 operated according to the instructions for use of the medicine.

Fourth, the soaked seeds should 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 dipping, but some can be directly sown after soaking, depending on the type of pesticide and soil moisture.

The fifth is that the liquid level is 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 swelling and exposing to expose the liquid surface, thereby reducing the soaking effect.

Six is ​​to stir well. The seeds should be thoroughly stirred in the liquid medicine to eliminate the air bubbles, so that the seeds are in full contact with the liquid medicine, and the seed soaking effect is improved.

Today, the knowledge about pesticide seed dressing is introduced here. To get more knowledge about pesticides , please pay attention to China Pesticide Net.
