Abstract Passion fruit (Passiflora spp.) yield is limited by several factors, including soil pathogens, such as Rotylenchulus reniformis (the reniform nematode) and Meloidogyne incognita Southern root-knot nematode). Understanding the behavior of different cultivars, within species passion could be important asset to search for sources resistance, therefore effective management phytonematodes. ...

Sedentary endoparasitic nematodes of plants induce highly specific feeding cells in the root central cylinder. From these, the obligate parasites withdraw all required nutrients. The feeding cells were described as sink tissues in the plant's circulation system that are supplied with phloem-derived solutes such as sugars. Currently, there are several publications describing mechanisms of sugar ...

The effects of a yard waste compost amendment and crop establishment on nematode populations and yields of suscep­ tible vegetable crops were determined in two tests in Florida in sites infested with the root-knot nematode, Meloidogyne incognita. Main plot treatments consisted of 269 mt/ha of a yard waste com­ post applied as a mulch, 269 mt/ha of the compost incorporated into the soil, and an ...

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...

The ability of nematode-trapping fungi to colonize the rhizosphere of crop plants has been suggested to be an important factor in biological control of root-infecting nematodes. In this study, rhizosphere colonization was evaluated for 38 isolates of nematode-trapping fungi representing 11 species. In an initial screen, Arthrobotrys dactyloides, A. superba, and Monacrosporium ellipsosporum were...

Breeding programs aiming at developing new nematode-resistant rootstocks are important because current rootstocks with adequate nematode resistance tend to have other undesirable viticultural characteristics (excessive vigor, excessive potassium uptake, poor resistance to phylloxera, rooting difficulty, inadequate zinc absorption). In this paper the authors develop a technique for evaluating re...
