Identification of fungi associated with rotylenchulus reniformis.
The objective of this work was to isolate and identify fungi associated with R. reniformis in cotton roots. Soil samples were collected in cotton fields naturally infested with R. reniformis and from cotton stock plants cultured in the greenhouse. Nematodes extracted from the soil were observed under the stereoscope, and discolored eggs and vermiform stages colonized with mycelia were cultured ...
متن کاملRotylenchulus reniformis Management in Cotton with Crop Rotation.
One-year crop rotations with corn or highly resistant soybean were evaluated at four locations for their effect on Rotylenchulus reniformis population levels and yield of a subsequent cotton crop. Four nematicide (aldicarb) regimes were included at two of the locations, and rotation with reniform-susceptible soybean was included at the other two locations. One-year rotations to corn or resistan...
متن کاملEfficacy of Paecilomyces lilacinus in Suppressing Rotylenchulus reniformis on Tomato.
Effects of rice-cultured Paecilomyces lilacinus on Rotylenchulus reniformis were studied in both greenhouse and field microplot tests with 'Rutgers' tomato. Numbers of R. reniformis were reduced (P </= 0.05) by P. lilacinus, with suppression in the initial greenhouse test ranging from 46 to 48% for two rice + P. lilacinus treatments; the rice-only treatment caused a nonsignificant reduction of ...
متن کاملThe Expressed Parasitism Genes in the Reniform Nematode (Rotylenchulus reniformis)
The reniform nematode (RN), Rotylenchulus reniformis, is an agriculturally important pest with a broad host range that results in a large economic impact in tropical, subtropical and in warm temperate zones. In an initial effort to understand the transcriptome and gene expression in RN, we present EST results that reveal numerous putative parasitism-related genes some of which play roles in pla...
متن کاملMicrosatellites reveal genetic diversity in Rotylenchulus reniformis populations.
Rotylenchulus reniformis is the predominant parasitic nematode of cotton in the Mid South area of the United States. Although variable levels of infection and morphological differences have been reported for this nematode, genetic variability has been more elusive. We developed microsatellite-enriched libraries for R. reniformis, produced 1152 clones, assembled 694 contigs, detected 783 simple ...
