Reproduction of Mi-Virulent Meloidogyne incognita Isolates on Lycopersicon spp.
Selection of detectable numbers of Mi-virulent root-knot nematodes has necessitated a greater understanding of nematode responses to new sources of resistance. During the course of this research, we compared the reproduction of four geographically distinct Mi-virulent root-knot nematode isolates on three resistant accessions of Lycopersicon peruvianum. Each accession carried a different resista...
متن کاملInteraction of Uromyces phaseoli and Meloidogyne incognita on Bean.
Uromyces phaseoli, the causal agent of bean rust, suppressed shoot and root growth of three bean cultivars, reducing root weight more than shoot weight. The greatest suppression of root weight was on the cultivar that appeared most susceptible by visual ratings of shoot symptoms. Meloidogyne incognita suppressed shoot and root growth of all test cultivars; root weight reductions differed among ...
متن کاملEffect of Temperature on Expression of Resistance to Meloidogyne spp. In Common Bean (Phaseolus vulgaris).
The effect of soil temperature on the expression of resistance in several common bean lines carrying resistance to root-knot nematodes (Meloidogyne spp.) was studied under controlled temperatures in temperature tank and growth chamber conditions. Resistance to M. javanica and M. incognita race 1 in bean lines A315, A328, A445, G1805, and G2618 was stable at 24-30 C. However, there was a signifi...
متن کاملVariability of Colletotrichum spp in common bean.
The Colletotrichum genus presents large genetic variability, as demonstrated by the occurrence of several pathogenic races and phenotypic traits. The objective of this study was to characterize 22 strains of C. lindemuthianum and Colletotrichum spp recovered from anthracnose lesions and bean scab, and to verify the relationship between species of the Colletotrichum genus, which inhabit anthracn...
متن کاملControl potential of Meloidogyne javanica and Ditylenchus spp. using fluorescent Pseudomonas and Bacillus spp.
Plant Growth Promoting Rhizobacteria (PGPR) have different mechanisms of action in the development of plants, such as growth promotion, production of phytohormones and antibiotic substances and changes in root exudates. These help to control plant diseases. In order to evaluate the potential of microorganisms in the control of Meloidogyne javanica and Ditylenchus spp., five rhizobacteria isolat...
