The influence of soil texture on reproduction and pathogenicity of Rotylenchulus reniformis on cotton
Nematropica 44 (1), 7-14
Abstract: Sixty-day duration studies were conducted under greenhouse conditions to evaluate the influence of three soil textures on reproduction and pathogenicity of three isolates of Rotylenchulus reniformis on Phytogen 375WF, Stoneville 5288B2F, and Stoneville LA887 cotton. Soil with clay content of 25.9% had a significant negative effect on reproduction of the nematode on all three cultivars. Soil texture had a significant main effect on heights of Stoneville 5288B2F and Phytogen 375WF plants. Across the cotton cultivars, there were significant differences in reproduction among the three isolates of reniform nematode. Overall, the Avoyelles isolate reached the highest population density. There was significant soil texture by reniform isolate interaction that affected population density of the nematode only for Phytogen 375WF.
