Helicotylenchus multicinctus found in a slash pine seed orchard in Georgia

Helicotylenchus multicinctus found in a slash pine seed orchard in Georgia

Plant Disease 73(6): 518

For several years, slash pines (Pinus elliottii var. elliottii) selected for high gum yield, growing in a seed orchard of the Georgia Forestry Commission in Bleckley County, have been declining. Yellowing of needles is the first apparent symptom. In January 1989, a limited survey of the orchard for plant-parasitic nematodes was conducted. H. multicinctus was found in all 6 samples and averaged 24 adults/100 g of soil. Males were present in 4 samples, and the female:male ratio was 3:1.
