Herbicide spraying can be performed, as a general rule, until wind speed exceeds what threshold?

Herbicide spraying is typically recommended to be conducted when the wind speed is below 10 miles per hour. This threshold is crucial to minimize drift, which can cause unintended damage to non-target plants and the environment. When spraying in higher wind conditions, there is an increased risk that the herbicide will be carried away from the intended area, leading to reduced efficacy on target species and potential environmental harm.

Controlling drift is essential for effective pest management and adherence to legal and safety guidelines regarding herbicide application. By keeping wind speeds below 10 miles per hour, applicators can ensure that the herbicide stays primarily within the target area, reducing the chances of contamination and improving the overall success of the application.
