Which weather conditions can affect the application of herbicides?

The correct choice highlights wind, rain, and temperature as critical weather conditions that significantly impact herbicide application.

Wind can carry herbicide spray beyond the target area, leading to unintended exposure of nearby plants or water sources, which can cause injury or contamination. Failure to account for wind speed and direction can lead to ineffective control of the intended weeds as well as environmental harm.

Rain affects herbicide efficacy as well; if it rains shortly after application, the herbicide may be washed off before it can properly penetrate the target vegetation. The timing of rain can therefore directly impact the success of weed management efforts.

Temperature is also essential because it can influence the volatility and stability of herbicides. Higher temperatures may increase the volatility of certain compounds, which can lead to drift, while excessively low temperatures can hinder the effectiveness of some herbicides, as they might not be absorbed adequately by plant tissues.

Considering these factors, it's clear why wind, rain, and temperature are paramount in determining the timing and success of herbicide applications.
