Screening Subterranean Clover (Trifolium spp.) Germplasm for Resistance to Meloidogyne species.
This study was conducted to identify lines of subterranean clover (Trifolium spp.) with resistance to Meloidogyne arenaria (Neal, 1989) Chitwood, 1949, race 1; M. incognita (Kofoid and White, 1919) Chitwood, 1949, race 3; and M. javanica (Treub, 1885) Chitwood, 1949. A collection of 134 subterranean clover lines was evaluated and all had intermediate to high susceptibility. Root galling was neg...
متن کاملEvaluation of nematicidal activity of ethanol extracts of Euphorbiaceae plants and constituents from Euphorbia fischeriana to Meloidogyne incognita (Kofoid and White) Chitwood
Ethanol extracts of 20 plant species (Euphorbiaceae) were assessed for nematicidal activity against the root-knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood. Out of these, four extracts: Croton tiglium, Euphorbia fischeriana, Leptopus chinensis and Ricinus communis caused 100% mortalities of the root-knot nematode at 1000 μg/ml for 72 h. The ethanol extract of E. fischeriana ex...
متن کاملNematicidal Activity of Leaf Extracts from Lantana camara L. against Meloidogyne incognita (Kofoid and White) Chitwood and its use to Manage Roots Infection of Solanum melongena L
Various concentrations of aqueous leaf extract of Lantana camara were assessed in vitro conditions against second stage juveniles (J2) of Meloidogyne incognita. The standard concentration ‘S’ of leaf extract was found to be highly nematostatic, where nematodes were completely paralyzed after 12 h and after 48 h of exposure, 96% of juveniles were killed at same concentration. However, the mortal...
متن کاملCombined Nematocidal Effect of Nonacosan-10-ol and 23a- Homostigmast-5-en-3β-ol on Meloidogyne Incognita (kofoid and White) Chitwood
The synergistic effect of three phytochemicals, nonacosan-10-ol, 23a-homostigmast-5-en-3β-ol and cisand transprotopinium were assessed in four combinations and three concentrations (5, 50 and 100 μg ml-1) against Meloidogyne incognita, in vitro and in planta on the tomato cultivar Riogrande. Additionally, an in vitro phytotoxicity test on tomato seedlings was performed with the same phytochemic...

Pangola digitgrass (Digitaria decumbens Stent.) can be used as a pasture grass or it can be harvested as hay. I t originated in Africa and has been in t roduced to other tropical and subtropical areas of the world. Winchester and Haysl ip (5) repor ted that the grass e l iminated populat ions of the root¬ nematode, Meloidogyne incognita acrita Chitwood and Oteifa, 1952. Overman (3) sampled 7...
