in this research the effect of two species of arbuscular mycorrhizal fungi, glomus mosseae and glomus intraradices on root knot nematode, meloidogyne javanica was investigated and in different treatments the effects of this interaction on parameters of plant growth , nematode infection and mycorrhizal development were evaluated.shoot fresh and dry weight significantly increased in mycorrhizal t...

In this report we describe experiments to investigate a simple virulence model in which Pseudomonas aeruginosa PAO1 rapidly paralyzes and kills the nematode Caenorhabditis elegans. Our results imply that hydrogen cyanide is the sole or primary toxic factor produced by P. aeruginosa that is responsible for killing of the nematode. Four lines of evidence support this conclusion. First, a transpos...

Meloidogyne incognita, Hoplolaintus galeatus, and North Carolina and Georgia populations of Belonolaimus longicaudatus were introduced singly and in various combinations with Fusarium oxysporum f. sp. vasinfectum on wilt-susceptible 'Rowden' cotton. Of all the nematodes, the combination of the N. C. population of B. longicaudatus with Fusarium promoted greatest wilt development. H. galeatus had...

N-Viro Soil (NVS) is an alkaline-stabilised biosolid that has been shown to suppress Meloidogyne incognita. In separate microplot studies, NVS was applied either alone at different rates (0, 25, 50, 75, 100 dry t ha−1), or in combination with M. incognitaresistant and M. incognita-susceptible cultivars, to different M. incognita initial densities (0, 37 500, 75 000 eggs/microplot). NVS suppress...

Microplot experiments were established in 1992, 1993, and 1994 to investigate the relationships among Macrophomina phaseolina, Criconemella xenoplax, mad Tylenchorhynchus annulatus on grain sorghum in Louisiana. A factorial treatment arrangement of two grain sorghum hybrids (De Kalb DK 50 and Pioneer hybrid 8333), three levels of M. phaseolina (0, 10, and 100 colony-forming units (CFU)/g soil),...

The herbicides alachlor, linuron, vernolate, and metribuzin were applied to plots treated with the nematicide fensulfothion or the insecticide phorate and planted to soybean in two locations in North Carolina. In 1976 treatment with fensulfothion + alachlor or vernolate, phorate + alachlor or metribuzin resulted in greater nematode population densities than no treatment, or treatment with fensu...

the present study is based on the investigation of a soil hyphomyces, paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode meloidogyne javanica on tomato in greenhouse conditions. p. lilacinus, effectively promoted the growth of plants inoculated with m. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...

Eosinophil responses typify both allergic and parasitic helminth disease. In helminthic disease, the role of eosinophils can be both protective in immune responses and destructive in pathological responses. To investigate whether eosinophils are involved in both protection and pathology during filarial nematode infection, we explored the role of eosinophils and their granule proteins, eosinophi...

two fungal species glomus mosseae and glomus intraradices as well as meloidogyne javanica nematode were used in order to evaluate the effects of arbuscular mycorrhizal fungi on control of different populations of root-knot nematode in tomato. a greenhouse test was established as factorial experiment based on completely randomized design with 8 treatments and 4 replicates followed by mycorrhizal...

Chickpea (Cicer arientinum L.) is one of the most dominant pulse crops in India, which contributes 38 percent area and 50 production pulses compare to total India. contains protein-2.1%, carbohydrates-61.5%, fat-4.5% more iron, calcium niacin content. The main constrain chickpea due parasitic nematodes (Meloidogyne incognita) about 14% global annual yield loss. Pseudomonas fluorescens a bacteri...
