Are those flea beetles worth spraying?

A few flea beetles in a field are not worth the time and investment to spray. They will not cause economic losses. Only when defoliation reaches 25% across the field and feeding pressure continues does it make sense to spray for flea beetles.

Seeing a few flea beetles is not a call to action, but it does suggest that regular scouting is necessary.
