17 Microdochium Patch 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 Trefenti ® nematicide/fungicide at 3.8 oz per 10,000 sq. ft., for up to 4 applications. Severe pressure may require a program approach along with 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 into root zone. See label for specific instructions. December 15 Instrata ® fungicide 9 fl oz M5, 3, 12
