What should we pay attention to when soaking seeds with pesticides? Please introduce the use of pesticides to soak seeds of crops need to pay attention to the following points (for reference): first, pay attention to the selection of dosage forms of medicament seed soaking using the diluent of the medicament, the medicament must be soluble in water. Can not soak the seeds with powder, because the powder is insoluble in water, the powder floats on the surface or sinks, and the seeds are stained unevenly, which can not achieve the purpose of seed soaking and sterilization. Second, the concentration of the medicament used in accurately preparing the solution for soaking seeds is not calculated according to the seed weight, but is generally calculated according to the content of the effective components of the medicament. The medicament concentration of seed soaking is generally related to the soaking time. When the concentration is low, the soaking time can be slightly longer, and when the concentration is high, the soaking time should be shortened. If the concentration is not accurately grasped, it is easy to cause drug damage or reduce the effect of seed soaking. Third, to master the time of seed soaking, there are certain time requirements for seed soaking. If the time is too long, it will cause drug damage, and if it is too short, it will not achieve the purpose of disinfection. The specific time of soaking seeds should be operated according to the instructions for the use of drugs. Fourth, the soaked seeds should be washed and dried. After soaking, the seeds with poor tolerance to chemicals should be washed with clean water as required to avoid drug damage. If there is no specific instructions for washing after immersion, there is no need to wash. Whether it needs washing or not, it should be spread out to dry after soaking, but some can also be sowed directly after soaking, which depends on the type of pesticides and soil moisture. Fifth, the liquid level should be higher than the seed when soaking the seed, the liquid level should be more than 16 cm higher than the seed, so as to prevent the seed from showing the liquid surface after absorbing water and reducing the effect of seed soaking. Sixth, fully stir the seeds into the medicine solution to fully stir, remove air bubbles, make the seeds fully contact with the medicine solution, and improve the effect of seed soaking.
