Which timing is least appropriate due to potential daytime heat and wind?

Explanation:
Midday timing is least appropriate because outdoor spray work is most effective when conditions are cool and calm. At noon the sun is high and temperatures peak, which increases evaporation and can reduce how well the pesticide sticks to targets. Daytime winds tend to be stronger, raising the risk of drift and off-target exposure. Early morning or late afternoon conditions are usually cooler and breezier in a calm way, helping the spray deposit stay on the intended area and work better. So spraying at noon is avoided to minimize heat-related losses and drift.
