Which of the following is a key factor in determining when to apply fumigation?

Weather conditions play a crucial role in determining the timing of fumigation applications. This is because various weather factors, such as temperature, humidity, and wind speed, directly influence the efficacy of fumigants, their ability to penetrate into the target area, and how long they remain effective. For instance, high temperatures often increase the volatility of fumigants, allowing them to disperse more readily, but may also cause them to evaporate too quickly. Conversely, ideal humidity levels can enhance the absorption of the fumigant into the target pest, improving control. Windy conditions can lead to off-target drift, posing risks to non-target organisms and reducing the effectiveness of the treatment. Understanding and monitoring weather conditions ensures that fumigation is applied under optimal circumstances for the best results.
