abstract in this study the effect of combination of trichoderma harzianum bi and salicylic acid were studied on root knot nematode (meloidogyne javanica) disease on tomato under green house conditions. the roots of tomato seedlings at six-leaf stage were inoculated with suspensions of fungal antagonist (106 conidia/ ml), 5mm salicylic acid and 2000 second-stage juvenile (j2). combined applicati...

The present study explored the efficacy of Bacillus spp. and protease production for biocontrol of the root-knot nematode Meloidogyne javanica in African violet media. Among 100 bacterial isolates from various soils, the highest nematode mortality was observed for treatments with isolate GM-18, which was identified as Bacillus subtilis based on cultural and morphological characteristics and 16S...

make sure that the soil is not infested before planting and that the transplants are free of nematodes. The type of cover crop used in peach orchards can have a considerable effect on the degree of attack by root knot nematodes and consequently on the growth and yield of the trees. In experimental plots in Georgia, trees on plots where root knot resistant cover crops were planted produced about...

root-knot nematodes are one of the limiting factors in seedling production and new olive gardens establishment in iran. in view of find resistance cultivars to root-knot nematodes, importance of careful identification of species and races are clarified. in order to investigate root-knot nematodes on olive, soil and root samples of gardens and nursery in gorgan area were collected. in this study...

Plant parasitic nematodes, including root knot nematode Meloidogyne species, cause extensive damage to agriculture and horticultural crops. As Vitis vinifera cultivars are susceptible to root knot nematode parasitism, rootstocks resistant to these soil pests provide a sustainable approach to maintain grapevine production. Currently, most of the commercially available root knot nematode resistan...

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...

cluding California (Altman and Thomason, 1971; Whitney and Duffus, 1986; Duffus and Ruppel, 1993). Resistance to root-knot nematode (Meloidogyne spp.) previously Disease of sugar beet caused by root-knot nematode was introgressed into sugar beet (Beta vulgaris L.) from wild beet [B. vulgaris ssp. maritima (L.) Arcang] and was demonstrated to be is manifested by galls that form on lateral roots ...

Multiple Brassica species commonly grown in Georgia were evaluated as a potential alternative to methyl bromide for management of root-knot nematode in vegetables. Brassica species produce general biocides called glucosinolates and were grown as cover crops and incorporated as green manures prior to transplanting of vegetable crop. Nematicidal activity of the Brassica species was based on net c...
