Advisory: Turf parasitic nematodes can be a serious pest of putting greens. If your greens are not responding to normal maintenance practices, it may be beneficial to send soil samples to a qualified lab for nematode analysis. To control nematodes, apply Divanem® nematicide at 1.2 oz per 1000 sq. ft. for up to 4 applications. Apply with enough water and a soil wetting agent to move Divanem into root zone. See label for specific instructions.
Always consult the product label for complete use and application information.
