What should be noted when soaking seeds with pesticides? Please explainThe following points should be noted when using pesticides to soak crop seeds (for reference):
1. Pay attention to choosing the formulation of the pesticideSeed soaking with pesticides uses a diluted solution of the pesticide, so the pesticide used must be soluble in water. Powders cannot be used for seed soaking, because powders do not dissolve in water; the powder floats on the water surface or sinks, and the seeds are coated unevenly with the pesticide, failing to achieve the purpose of sterilizing the seeds by soaking.
2. Accurately prepare the pesticide solutionThe pesticide concentration used for seed soaking is not calculated according to seed weight; it is generally calculated according to the content of the active ingredient of the pesticide. The pesticide concentration for seed soaking 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 controlled, pesticide damage is likely to occur or the seed soaking effect will be reduced.
3. Master the soaking timeSeed soaking with pesticides has a certain time requirement. If the time is too long, pesticide damage will occur; if it is too short, the disinfection purpose will not be achieved. The specific soaking time should be carried out according to the pesticide instructions.
4. The soaked seeds must be rinsed and driedFor seeds with poor tolerance to the pesticide, after soaking they should be rinsed with clean water as required to avoid pesticide damage. If there are no specific instructions to wash with water after soaking, then there is no need to wash with water. Whether washing with water is needed or not, generally after soaking the seeds should be spread out to dry, but in some cases they can also be sown directly after soaking; this depends on the type of pesticide and the soil moisture conditions.
5. The liquid surface must be higher than the seeds During seed soaking, the liquid surface must be more than 16 cm above the seeds, so that after the seeds absorb water and swell, they will not be exposed above the liquid surface and reduce the seed soaking effect.
6. Stir thoroughlyAfter putting the seeds into the pesticide solution, stir thoroughly to remove air bubbles, so that the seeds fully contact the pesticide solution, improving the seed soaking effect.
