When is the best time for outdoor plants to kill insects (pesticides)?

In March, people seldom get sick. It is particularly easy to get sick in high humidity and high temperature seasons. Pay special attention to disease prevention in summer. This medicine must have been taken at the peak of the disease. If it is a preventive measure, you can take it at any time. But we should pay attention to the weather. It's no use calling if it rains today. If it is sunny, it is best to play after 5 pm, so it is not easy to cause drug damage. And it's best to choose in windless weather. Be sure to pay attention to the dosage. Carbendazim and chlorothalonil can be used for prevention and control. Treatment depends on the specific disease. In fact, the best thing is physical therapy, which can be removed directly. A very eco-friendly way, provided that there are only a few plants in your home.
