Applying pesticides before rainstorms can lead to significant issues, primarily because rain can wash the pesticides off the intended target areas. When pesticides are applied to surfaces such as plants, soil, or structures, they need time to adhere and be absorbed effectively. If it rains shortly after application, the precipitation can cause the pesticides to be diluted or completely removed from surfaces, reducing their effectiveness in controlling pests. This not only wastes the pesticide but can also lead to environmental concerns, as the runoff can contaminate water sources or affect non-target organisms.

The other factors mentioned in the other choices do not accurately reflect the primary reason for avoiding pesticide application just before rain. For instance, while evaporation could be a concern in very hot conditions, it is not the primary issue related to rainfall. Similarly, while rain can influence absorption rates, in the context of timing application before storms, the risk of wash-off takes precedence. Lastly, pesticide effectiveness in high humidity is not directly related to the timing of rain before application.
