verticillium wilt verticillium dahliae is now a days commonplace in olive orchards in north of iran. root-knot nematode, meloidogyne javanica, as well is one of the most widely disseminated plant parasitic nematodes in olive orchards of iran. this study was arranged to find the effects of two sets of pot beds on these pathogens' interaction. microsclerotia of verticillium dahliae and j2s o...

Okra [Abelmoschus esculentus L., Moench] a native of South-Africa and commonly known as ‘Bhindi’ is an annual malvaceous vegetable crop, especially grown in tropical subtropical climates. It also called “perfect villager’s vegetable”. Root-knot nematodes are considered among the top five major plant pathogens first ten most important genera parasitic world. Amongst nematodes, root-knot nematode...

true myrtle, myrtus communis l belonging to myrtaceae family is an important medicinal herb in traditional medicine and pharmaceutical industries in iran. moreover because of  being evergreen, having dense foliage and ease of pruning, it is planted at steep slopes, grasslands, boulevards and sidelines of parks as an ornamental shrub or hedge of green. it is distributed in southern europe, asia,...

To determine the presence and level of root-knot nematode (Meloidogyne spp.) infestation in Southern California bell pepper (Capsicum annuum) fields, soil and root samples were collected in April and May 2012 and analyzed for the presence of root-knot nematodes. The earlier samples were virtually free of root-knot nematodes, but the later samples all contained, sometimes very high numbers, of r...

Root-knot nematodes are globally the most aggressive and damaging plant-parasitic nematodes. Chemical nematicides have so far constituted the most efficient control measures against these agricultural pests. Because of their toxicity for the environment and danger for human health, these nematicides have now been banned from use. Consequently, new and more specific control means, safe for the e...

pasteuria penetrans is a bacterial parasite of some plant parasite of nematodes whichcan attach to the cuticle of nematode. differences in attachment of p. penetrans spores to the second stag juvenile (j2) cuticle may provide evidence for nematode cuticle diversity even between different ages of j2s. for investigating this purpose, we studied the effect of different ages of the same population ...

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 ...

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. ...

The present study is based on the investigation of a soil hyphomyces, Paecilomyces lilacinus, an opportunistic bio-control agent. The egg pathogenic fungus Paecilomyces lilacinus is a unique strain with a wide range of activity against the most important plant parasitic nematodes. The aim of this study to evaluate the efficiency of P. lilacinus on parasitic nematodes Meloidogyne javanica on tom...
