Excuse me, in what weather and in what time period should the medicine for sweating be effective?

The application of soil sealing agent in dry land needs five conditions, and the overall effect will be good.

1, humidity. After the rain, under the condition of ensuring the soil moist.

2. temperature. If the temperature is low, it is not good for the efficacy.

3. the wind. On windy days, pesticides can't fall on the soil, and the effect is not ideal.

4. Moisture. This is very important. There is a lot of water in the machine, but the dosage needs to be increased. The dosage of 10 mu increased to 13 mu, and the effect was just right.

5, the ground should be flat. After planting the land, it can cover all aspects through suppression, clods crushing and uniform application of drugs, and the effect is ideal.

I still want to use medicine without growing vegetables in the next crop. If you grow vegetables, there will be herbal residues, so be careful when using drugs.
