Question: 1 / 400

When should you avoid spraying to prevent drift?

During periods of low humidity

When temperatures are below freezing

When wind speeds are over 10 mph or during periods of calm/inversion

Spraying should be avoided during high wind speeds (over 10 mph) or periods of calm and inversion in order to prevent drift. Low humidity and dry soil are not factors that contribute to drift. Spraying is typically not done when temperatures are below freezing, but this is not specifically to prevent drift. Instead, it is to avoid damaging plants with the spray and to ensure proper coverage.
