Factors that should be considered when using pesticides outdoors, in addition to soil factors, are:

• A. Expected rainfall
• B. Wind
• C. Humidity and temperature
• D. All of the above

Answer: (D)

When applying pesticides outdoors, conditions beyond soil type shape how well the product works and how safe it is for people and the environment. Rainfall matters because rain soon after application can wash the product off leaves, reduce effectiveness, and increase off-target movement into waterways or runoff. Wind is a key factor because even light gusts can carry droplets away from the target, creating drift that risks non-target plants, people, or nearby water sources; choosing calm conditions and using drift-reducing practices helps. Humidity and temperature influence how droplets behave after they’re sprayed: temperature can affect volatility and degradation rates, while humidity affects how quickly droplets dry and deposit on the target. Because each factor can change efficacy and risk in different ways, all of these considerations should be evaluated before outdoor use. Labels commonly specify wind and rainfast intervals and temperature or humidity guidelines to help manage these risks.
