Before actual pesticide application, what should be confirmed?

• A. That there are no recent changes that could pose risks to safety or the environment.
• B. The color of the pilot's uniform.
• C. The weather forecast for the next month.
• D. The market price of the pesticide.

Answer: (C)

The key idea here is that weather directly determines safety and effectiveness of a pesticide spray. Wind speed and direction, temperature, humidity, and the chance of rain influence drift, volatilization, evaporation, and how well the product will work on the target area. Having a reliable weather forecast helps you decide whether to proceed, delay, or adjust application parameters to minimize exposure and environmental impact. Among the options, checking the weather forecast is the one that provides the information needed to gauge those immediate risks. The other items don’t affect the safety of the actual operation: uniform color has no bearing on drift or exposure, market price doesn’t change the application risks, and while staying aware of changes to labels or safety advisories is important, it doesn’t address the weather-related safety conditions for that moment.
