Click here to see the recent product sampling report from TSA. Reductions in nematode counts are reported. Despite these results, TSA still pursues Curfew application! The product sampling process needs closer analysis dues to concerns about the sampling size and methods (e.g., controls for extraneous variables, lack of comparative analysis of Curfew), data reliability, and related procedures. Given the severe risks that are involved in this issue, it is recommended that this type of analysis should be conducted by neutral third party scientists with no vested interest in the outcomes of the study.

Curfew application can create a problematic rebound effect that actually increases nematode populations. From Dr.William T. Crow, Professor of Nematology, University of Florida: “When you treat with a very effective nematicide with little residual activity like Curfew you knock the nematode numbers down and establish a better root system.  Then, because you have more roots for the nematodes to eat, nematodes surviving the treatment may build up to higher numbers than they would have had with no treatment.  This is one of the reasons I try to get folks to focus more on turf health than nematode numbers.”

TSA is strongly encouraged to communicate its progress in adopting integrated pest management practices applied by other golf courses. TSA is also challenged to move toward innovative xeriscaping methods to modify areas where golfers rarely or never hit balls. In golf courses across the US, these areas are being replaced with native, slow growing, drought-tolerant groundcovers and other playable surfaces that are designed by a landscape architect. Besides creating more aesthetically pleasing golf courses, TSA can reduce reliance on pesticides, lower water bills, and more efficiently use funds for maintenance. TSA is respectfully requested to engage all impacted neighborhoods in planning for and implementing these developments.
