A: Spraying is about timeliness. For drugs with a residual effect of 17 to 21 days, it is usually sprayed once every 15 days. In the rainy season, depending on the amount of rainfall, the spray interval should be shortened as appropriate. In case of heavy rain, it should be re-sprayed after fine weather. If the two adjacent drugs are acid-alkaline, the interval should be strictly observed to prevent acid-base neutralization. In short, the specific situation should be specifically addressed, and the application of the disease should not be taken into account.
