Fusiform Rust in Planted Slash Pines: Influence of Site Preparation and Spacing
Abstract:Site preparation significantly increased the incidence of fusiform rust in five of six slash pine (Pinus elliottii Engelm. vat. elliottii) plantations studied in southeastern Georgia. On the five sites, subplots receiving intensive site preparation had more trees infected, more trees with potentially lethal galls, and more galls per tree than subplots receiving minimal treatments. Also there were more trees with multiple stem galls in the more intensively prepared subplots. Spacing significantly affected the incidence of rust on only one of six sites, and there was no apparent relationship between the amount of rust and estimated site index. Forest Sci. 18:70-75.
