If you suspect damage from or have a history of Annual Bluegrass Weevil, insecticide applications are based on insect development and will vary due to weather conditions and insect development. The initial applications for the control of Annual Bluegrass Weevil are based on the monitoring for adults, growing degree days and plant phenology. For all applications, visit WeevilTrakPlus.com for proper timing. Recommendations contained in this Syngenta Agronomic Program are estimates only and should only be used in isolation for building individual spray programs. Syngenta does not warrant or certify the results of using the information contained herein. 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.
