2027 – Greens – Creeping bentgrass/Poa annua – Great Lakes – 14-Day (WI)
Turfgrass Parasitic Nematodes: Nematodes can be a serious pest of golf course putting greens. To accurately diagnose nematode populations and their distribution, submit 15-20 1” diameter soil cores taken in a zig-zag pattern on the green to a qualified laboratory for a nematode assay. To manage nematode activity, a programmatic approach with Divanem ® nematicide and Trefinti ® nematicide/fungicide applied every 21 to 28 days is recommended, up to 6 applications. For optimum results, apply with adequate water and include a soil wetting agent. Apply 0.25” of irrigation immediately after application. See label for specific instructions.
