| Abstract/Contents: | "Annual bluegrass (Poa annua L.) is a widespread serious weed species of golf turf. Several years ago strains of the bacteria Xanthomonas campestris pv. poannua were identified as causing a bacterial wilt of annual bluegrass and were evaluated as a biocontrol agent. While shown to be effective in controlling annual bluegrass, commercialization of Xanthomonas campestris pv. poannua had been halted by the lack of success in developing a stable and viable dry formulation of bacteria that could be commercialized. Eco Soil Systems, Inc. is developing for commercialization a strain of Xanthomonas campestris pv. poannua that is marketed as a liqiud formulation containing active bacteria in high concentrations. This product has the flexibility of being marketed as a packaged material delivered directly to the end user or, in the near future, increased at the application site in conjunction with the BioJectā¢ on site fermentation system. In the fall of 1998, Eco Soil Systems, Inc initiated an EUP program to commercially evaluate the effectiveness of Xanthomonas campestris pv. poannua for the management of the annual bluegrass in golf and athletic turf. The program consists of a series of four to six fall applications followed by a similar number of applications in the spring. The objective of this program is to cause significant levels of infection in annual bluegrass plants which would weaken them and make them more susceptible to mortality caused by cold stress over the winter, and by heat and drought stress in the early summer. Over 150 golf courses are participating in this EUP program. Leaf tissue analysis of Poa annua plants sampled from treated golf courses shows a 95% infection success rate. Initial infection success rate. Initial infection symptoms are seen as an etiolation of seed stalks and stems that is followed by subsequent chlorosis and thinning of the affected plants. Infection and symptoms occurred in both the annual (P. annua ssp. annua) and perennial (P. annua ssp. reptans) annual bluegrass subspecies. Desirable species such as creeping bentgrass (Agrostis palustris Huds.) and velvet bentgrass (Agrostis canina L.) are not affected by Xanthomonas campestris pv. Poannua regardless of growth stage." |
