From this study we could conclude that, resistant cultivars are the single effective solution to management of root-knot nematode population avoid crop losses. Also, it is essential use in situations where nematodes present and when control advantageous yields. However, reported moderately cultivars, viz. Gujarat Rajmash, Amber (IPR 96-4) HUR15 belong secondary gene pool with cross-compatibilit...

Granular and liquid commercial humates, with micronutrients, and a microbial fermentation product were compared in several combinations with nematicides for their effects on cotton lint yield and root-knot nematode suppression. Fumigant nematicides effectively reduced cotton root galling caused by root-knot nematodes, and cotton lint yields increased. Organophosphates and carbamates were not ef...

Root-infecting nematodes are commonly found on white clover in New Zealand pasture where they reduce yield, nitrogen fixation, and persistence. The dominant root-knot nematode on white clover in New Zealand is confirmed in this study as Meloidogyne trifoliophila by isozyme phenotype comparison with the type population from Tennessee. Results from a host differential test differed in the host ra...

The increased concern for environmental and health hazards have called for a reduction in the use of synthetic nematicides for nematode control. Experiments were, therefore, conducted to ascertain the nematicidal potential of castor bean’s crude extract and its five lower concentrations with water as control. In the in vitro studies, crude castor bean aqueous extract and 10, 20, 30 and 40% diff...

Root-knot nematodes are obligate parasites of a wide range of plant species and can feed only on the cytoplasm of living plant cells. In the absence of a suitable plant host, infective juveniles of strain VW9 of the Northern root-knot nematode, Meloidogyne hapla, when dispersed in Pluronic F-127 gel, aggregate into tight, spherical clumps containing thousands of worms. Aggregation or clumping b...

This study was conducted to identification and distribution Root-knot nematode species in lavender fields where Lavandin (Lavandula × intermedia Emeric ex Loisel. var. Super) cultivated an area of about 625 ha Isparta Burdur Provinces Turkey. A total 60 samples were collected autumn 2020. Root knot molecular determined by species-specific primers from egg masses. The 17 taken found be infected ...

A screening of several Chinese medicinal herbs for nematicidal properties showed that Arisaema erubescens (Wall.) Schott tubers possessed significant nematicidal activity against the root-knot nematode (Meloidogyne incognita). From the ethanol extract, two nematicidal flavone-C-glycosides were isolated by bioassay-guided fractionation. The compounds were identified as schaftoside and isoschafto...
