Does spraying herbicide when there is dew actually work?

Pesticides are now an indispensable helper for farmers in agricultural production. From the prevention and control of pests and diseases to the regulation of crops by growth hormones, it must be said that pesticides have made huge contributions to agriculture. On the topic of whether spraying pesticides when there is dew is good or not, people have always argued endlessly. So does spraying herbicide when there is dew work?

Dew and rainy days are not suitable for spraying herbicide. When there is dew on the crops, on the one hand it will dilute the herbicide, thereby reducing the effectiveness of the herbicide. On the other hand, when the sun comes out, the dew will evaporate, and in that case the herbicide will also evaporate along with the dew, so naturally the weeding effect will not be obvious. It is best to choose a clear, windless day to spray herbicide.
