Abstract/Contents: | "Annual bluegrass (Poa annua L.) is a common grass species found on golf courses. Although a weed, it is managed as the primary turf on many putting greens in the Northeast. Poa annua is susceptible to numerous diseases including bacterial wilt, caused by Xanthomonas translucens pv. poae. The bacteria multiply in xylem vessels, causing wilting and necrosis. Few control options exist for this disease. Copper compounds can be used but have a high level of phytotoxicity. Antibiotics are not labeled for use on golf courses. We have studied induced resistance as a possible control for this disease. Trials were undertaken to study the effects of exogenous applications of salicylic acid, 2,6-dichloroisonicotinic acid (INA), Actigard® (acibenzolar-S-methyl), Aliette® (fosetyl-aluminum), beta-amino butyric acid (BABA), Messenger® (purified harpin protein), and dihydrogen potassium phosphate (K2HPO4). These chemicals have been shown to induce resistance in other plant species by mimicking systemic acquired resistance. Our results demonstrate that INA, SA, and Actigard are the most effective in inducing resistance, frequently increasing survival to between 30 and 60% in greenhouse trials conducted under high humidity (> 75%) and high temperatures (25°C). Some plant survival was also seen using Aliette, K2HPO4, and BABA but at lower levels. Harpin appears to be minimally effective. No previous work has been done on the efficacy of induced resistance in controlling bacterial wilt on annual bluegrass." |
