Delineation of Fusiform Rust Hazard Based on Estimated Volume Loss as a Guide to Rust Management Decisions in Slash Pine Plantations
Abstract:Using published data, an empirical model is derived to approximate volume loss due to fusiform rust in slash pine plantations. Specifically, cumulative percentage volume loss at age 15 years is estimated as a function of percentage-rust-associated mortality at age 15 years, percentage stems infected at age 5 years and percentage trees infected at ages 5-10 years. Volume losses of <15, 15-35, and >35 percent at age 15 years are arbitrarily defined as low-, moderate-, and high-rust hazard, respectively. The corresponding percentages of trees with rust were <18, 18-43, and >43 at age 5 years, and <44, 44-77, and >77 at age 10 years. Using these approximations, a regional rust-hazard map for 10-year-old slash pine plantations is developed from rust survey data and potential rust management strategies are discussed for the region and for planatations.
