During which weather condition should you avoid spraying pesticides to minimize spray drift?

Spraying pesticides during windy conditions can lead to significant spray drift, which is the movement of pesticide particles away from the intended application area. Wind can carry the spray to unintended locations, potentially harming non-target plants, animals, or even people. Ensuring accurate application without drift is critical for both effectiveness and safety.

While foggy weather can also complicate visibility and may affect application, it typically does not cause drift in the same way wind does. Rainy weather can wash away pesticides before they have a chance to adhere to surfaces, affecting efficacy, but it doesn’t generate the same immediate risk of drift as wind. Cold temperatures can impact the performance of pesticides, affecting how they adhere and function, but again, they do not facilitate the movement of spray like windy conditions do. Therefore, avoiding spraying during windy conditions is essential for effective and safe pesticide application.
