When will the pesticide be hit?

The suitable time for spraying pesticides for flowers is generally summer, and the specific period is the flourishing period of flower growth. Summer is a suitable period for the growth of many kinds of flowers, but because of the high temperature and good light conditions, it is also a prosperous period for breeding diseases and insect pests, so spraying pesticides or plant growth regulators for flowers at this time can exert its efficacy effectively.
