Spraying in cool temperatures

Cool cloudy days following cool night are not the best for herbicide spraying. Warm sunny days and warm nights are ideal.

Applications made when cool cloudy days follow cool nights will result in lower herbicide efficacy than applications made in warm sunny days. Cloudy days don’t provide the photosynthetic activity required for many herbicides. Please see the updated article on spraying in tough conditions.
