Description: Fusiform rust [Cronartium quercuum (Berk.) Miyabe ex Shirai f. sp. Fusiforme] infection rates in east Texas increased to nearly 50 percent in slash pine (Pinus elliottii Engelm.) and about 15 percent in loblolly pine (Pinus taeda L.) plantations during the 18-year period from 1969 to 1987. New data from the East Texas Pine Plantation Research Project showed that fusiform rust infection rates in slash pine peaked in 1987, then decreased to about 15 percent by 2002. For loblolly pine, the rates stabilized around 10 percent after 1987, then decreased to around 5 percent by 2002. The peak infection rates occurred circa 1987 when plantations were 8 to 11 years old. This 32-year continuous record of fusiform rust incidence in east Texas indicates that infection rates are relatively stable (about 10 percent) for loblolly pine and much greater (up to 50 percent) for slash pine.
