Program '11: The Best Fungicide Program for YOUR Putting Greens
4 likes8,995 views
The document provides guidance on developing a fungicide program for putting greens. It recommends 1) identifying key diseases based on location and history, 2) determining when diseases are normally active using weather data, and 3) selecting fungicides to control expected diseases during each application window. Resources for fungicide selection include product labels, reference manuals, and an online disease management utility. A sample program is outlined targeting common diseases at different periods using appropriate fungicides and application timings.

- 5. The diagnostic lab saw some bacteria in our samples.
- 6. Which bacteria did they see? Is it a pathogen? The diagnostic lab saw some bacteria in our samples.
- 7. Which bacteria did they see? Is it a pathogen? The diagnostic lab saw some bacteria They didn’t say, but in our samples. clearly we have a huge bacteria problem here.
- 8. Acidovorax sp. Xanthomonas translucens No suspected pathogens
- 9. Identifying the Acidovorax species associated with creeping bentgrass putting greens.
- 10. Bacteria Research Plans for 2011 • closing in on an identification for the Acidovorax species associated with creeping bentgrasss • inoculations of field plots with Acidovorax and Xanthomonas isolates to determine their pathogenicity • evaluation of antibiotics and other compounds as possible control practices
