Dieback of terminal shoots of slash and loblolly pine seedlings was first observed in 1977 in nurseries from Texas to Florida. Phomopsis spp., Diplodia gossypina, and Fusarium moniliforme var. subglutinans were isolated from diseased tissues. Inoculations indicated that D. gossypina and F. moniliforme var. subglutinans were pathogenic.
