Larvae of Meloidogyne spp. were readily infected with the endoparasite Bacillus penetrans by exposure to an aqueous suspension of spores from infected root-knot nematode females, or by passage of larvae through a shallow layer (50 cm(3)) of spore-infested soil. Infection severely reduced motility of second-stage larvae through soil. Bacillus penetrans exhibited a distinct host specificity in th...

Five sweetpotato [Ipomoea batatas (L.) Lam.] cultivars (‘Beauregard’, ‘Excel’, ‘Jewel’, ‘Hernandez’, and ‘Porto Rico’) were evaluated for resistance to three root-knot nematode species: Meloidogyne arenaria (Neal) Chitwood (race 2), M. incognita (Kofoid & White) Chitwood (race 3), and M. javanica (Treub) Chitwood. Resistance screening efficiency was assessed in both 400-cm3 square pots and 150-...

Toprak, bitki paraziti kök-ur nematodlarının çoğalmaları ve varlıklarını sürdürmeleri için iyi bir gelişme ortamıdır. Bu çalışmada, Gaziantep Osmaniye il ilçeleri sebze alanlarındaki Meloidogyne incognita, M. javanica, arenaria luci türleri ile bulaşık olan toprakların tekstürü (Suyla Doygunluk (%), pH’ı elektriksel iletkenliği (EC)) incelenmiştir. Çalışma sonunda dört nematodu türünün bulunduğ...

A giboma é uma hortaliça da família das solanácea originária África e muito cultivada neste continente emergente no Brasil. Os nematoides de galhas, gênero Meloidogyne, causam grandes prejuízos nas hortaliças, com destaque para as solanáceas. Assim, objetivou-se avaliar a influência concentração inóculo inicial M. javanica desenvolvimento giboma. Utilizou-se o delineamento inteiramente casualiz...

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...

Meloidogyne enterolobii is widely considered to be an aggressive root-knot nematode species that is able to reproduce on root-knot nematode-resistant tomato and pepper cultivars. In greenhouse experiments, M. enterolobii isolates 1 and 2 from Switzerland were able to reproduce on tomato cultivars carrying the Mi-1 resistance gene as well as an N-carrying pepper cultivar. Reproduction factors (R...
