First, we must fully understand the performance of pesticides and accurately grasp the amount of pesticides. When seed dressing, the weight of the seed, the amount of the drug and the amount of water should be weighed. The dilution should be uniform to prevent the drug from being damaged by too much drug. If the dose is too small, the effect of prevention and control will not be achieved. When some pesticides are used for seed dressing, it is better to dry mix, wet mix and stuffy are easy to produce phytotoxicity. Therefore, before seed dressing, you should fully understand the performance of pesticides and accurately grasp the amount of pesticides.
Second, pay attention to the seed dressing method. When wheat is mixed with phoxim, the pesticide should be diluted with water, then mixed with wheat, and covered with scum. Wheat with rickett seed dressing, the seed should be sprayed with water to the wet, then the agent is evenly mixed on the seed, and then immediately sown or dried and then sown. If you want to use seed dressing with pesticides and seed dressing with fungicides, you should first mix the insecticides, mix the fungicides after the piles, and then immediately sow. Wear masks and long-sleeved clothes during seed dressing. After mixing seeds, the remaining pesticides should be cleaned up in time to prevent poisoning of humans and animals.
Third, try to do as much as possible with the mix, not for a long time. After the wheat is seeded with the insecticide, it is generally piled up for 2-3 hours, up to 5-6 hours, and the seed is immediately sown after being absorbed by the wheat seed. After the wheat is mixed with the fungicide, it should be sown immediately or immediately after being dried. Seeds mixed with good medicine should not be exposed to sunlight, so as not to affect the efficacy.
