Pinus damping-off investigations in southern Queensland

Abstract

The organisms associated with damping off in Pinus nurseries in southern Queensland were investigated. The potential pathogenicity of a number of Pythium, Phytophthora, Rhizoctonia and Fusarium species to Pinus seedlings was checked in greenhouse inoculation tests.
A damping-off control experiment showed that soil drenches of captan, thiram and copper· oxychloride will control the disease in seedlings of slash pine (Pinus elliottii var. elliottii).
