Pathogenicity studies with Meloidogyne incognita and Rotylenchulus reniformis on two varieties of grape vine Rao K. Tirumala, Seshadri A. R. Department of Entomology, A. P. Agril. University, Agricultural College, Bapatla. Presented at Nematology Symposium held at Coimbatore, India in February, 1981 Abstract Eight Pathogenicity experiments, four on M. incognita and four on R. reniformis were conducted. These studies revealed that 10 days old seedlings of grape (Anab-E-Shahi) were killed by M. incognita within 30 days of inoculation with an initial population level of 1000 nematodes per pot (500 g soil) and above, while 1,00,000 larvae of Rotylenchulus reniformis were able to kill only 3 plants out of 7. No death was observed in seedlings of 60 days and above and also in cuttings of 4 months age. Inoculations on 60 days old seedlings at 90 days after inoculation showed more damage by 1000 level of nematodes than 10,000 level in both the nematodes. Top | |
