Nostoc, is a cyanobacterium that produces thick, olive-green to brown, gelatinous masses on nursery roadways, walkways and production areas. While it does not impact crops directly, patches of this slimy invader are slipping hazards for you and your workers. Most pesticides used in nurseries are ineffective. But, what was once a perplexing and frustrating problem can now be controlled with relative ease. In this presentation Dr. Neal will review five years of research on strategies to control nostoc in container nurseries.
