ABSTRACT
Control Use seed that does not have significant levels of the pathogen. Treat infested seed with hot water (50º C for 25 minutes). Practice careful sanitation at transplant nurseries. Disinfect benches, seed trays, mowers, and other production equipment. Prevent transfer of the pathogen on worker hands, clothing, and footwear by using sanitizing agents. Irrigate so that plants dry quickly after watering, and avoid using high-pressure irrigation systems that lead to water-soaking of leaves. Chemical control in the form of copper sprays is of limited benefit.
