What are some factors that you should think about before spraying?

When spraying pesticides, there are several factors to consider in order to ensure the most effective and safe application. While some of the options presented may seem important, they do not cover the full range of concerns. For example, while application speed and droplet size (A) may affect the accuracy and coverage of the spray, they do not address the potential negative effects of environmental conditions. Soil type and equipment condition (C) may impact the efficiency of the equipment, but do not directly relate to the proper application of the pesticide. Similarly, humidity and temperature (B) may affect the effectiveness of the pesticide, but they do not encompass all possible factors to consider. The correct answer, D, includes temperature, wind, and droplet size, all of which can greatly impact the safety and effectiveness of the spraying process.
