In wet seasons, seedling establishment is the major problem of the Queensland processing vegetable industry with average seedling losses as high as 70%. An industry seminar was held in 1990 to review seedling survival techniques being used in other industries. This seminar identified new, environmentally friendly chemical which were highly effective when used as seed dressings to control Pythium and Rhizoctonia. This project examined the use of seed chemicals to reduce seedling losses from Rhizoctonia and Pythium and the biological control of Aphenomyces.
