Reaction of Pigeonpea Cultivars and Germplasm Accessions to the Root-knot Nematode, Meloidogyne javanica.
Meloidogyne javanica is an important nematode pest of pigeonpea. Thirty-four pigeonpea cultivars and 227 germplasm accessions were evaluated for resistance to M. javanica based on number of galls, egg masses, size of galls, and area of root covered with galls. Galls were not formed on 75% of the cultivars, and no egg masses were observed on the roots of four cultivars (UPAS 120, Pant A3, CO 1, ...
متن کاملa study on the reaction of six tomato cultivars against root-knot nematode meloidogyne javanica under greenhouse conditions
the reaction of four field tomato cultivars (super strain b, super chief, mobil, and royal) along with two greenhouse cultivars (polaris and es 1002 f1) was evaluated agianst m. javanica under greenhouse conditions. the soil around tomato seedlings (bearing 5-6 leaves) was inoculated with two levels of the nematode inoculum i.e. 1000 and 2000 eggs as well as second stage juveniles per every kg ...
متن کاملEffect of chitosan on root-knot nematode, Meloidogyne javanica
In our study two different chitosan with low and high molecular weight at different dilutions i.e. standard, 1:1, 1:2, 1:3, 1:4, 1:5 and 1:10 were evaluated against root-knot nematode, Meloidogyne javanica in vitro and in vivo under greenhouse conditions. In vitro results revealed that both chitosan with all used concentrations significantly reduced the egg hatching when compared to control. No...
متن کاملEFFECT OF SOME INDIGENOUS ISOLATES OF Trichoderma harzianum ON ROOT KNOT NEMATODE, Meloidogyne javanica (TREUB) CHITWOOD
Soil and root samples of tomato were collected from root knot nematode-infested fields of fifteen different localities of Malakand and Swat (NWFP) Pakistan in 2006-07 and Trichoderma harzianum was isolated from these samples. These isolates were tested against Meloidogyne javanica (Treub) Chitwood in the in vitro. Isolates Th1 and Th9, collected from Jabban and Shamozai were more aggressive tha...
متن کاملSusceptibility Assessments of Tomato Genotypes to Root Knot Nematodes, Meloidogyne javanica
Root-knot nematodes, Meloidogyne spp., are one of the important plant parasitic nematodes of tomato in the world. The most suitable control method of plant parasitic nematodes is the use of resistance sources and tolerant cultivars. In the earlier studies, the results showed thatonly 2% (19 out of 537 varieties) were resistant and tolerant to the root knot nematodes. In the supplementary studie...
