Interaction of Rotylenchulus reniformis, Soil Salinity, and Cotton

C. M. Heald, M. D. Heilman


Rotylenchulus reni]ormis occurred equally in relatively non-saline (4.0 mmhos/cm) and highly-saline (16.5 mmhos/cm) soils in sampling transects across zones of depressed plant growth in six Texas cotton fields. Results from greenhouse pot experiments indicated progressive positive interaction of salinity and R. reni[ormis pathogenicity in the range 6-18 mmhos/cm. Key Words: Reniform nematode, Gossypium hirsutum.
