root-knot nemaode which causes extensive damage to legumes and cerealshas beenreported in many countries. the nematods has been observed on legumes, roots in manyregions of the world, causing swollen root and yield reduction. in order to evaluate the effect ofirrigation interval on reproductive traits of root-knot nematode, and the damage inflicteduponnavy bean, a study was conducted in 2011 in...

In order to study the effects of drought stress and mycorrhiza fungi on establishment rate and some growth-morphological traits ofZiziphora clinopodoides, pot experiments were conducted as factorial design based on a completely randomized design at the research greenhouse of agricultural faculty, Ferdowsi University of Mashhad in 2014; pots were combined as four levels of drought stress includi...

Root-knot nematode is an important pest in agricultural production worldwide. Crop rotation is the only management strategy in some production systems, especially for resource poor farmers in developing countries. A series of experiments was conducted in the laboratory with several leguminous cover crops to investigate their potential for managing a mixture of root-knot nematodes (Meloidogyne a...

Twelve soil drenches over a period of 30 days with DBCP concentrations of 40 microg/ml did not completely prevent infection of tomato plants by root-knot nematode juveniles. Repeated DBCP drenches of 40 microg/ml halted gall development during the drenches, but 10 days after drenching was discontinued galls were apparent. DBCP drenches at 200 microg/ml prevented tomato root development, and 40 ...

Abstract— The expression of the genes encoding inhibitors serine ( ISP ) and cysteine ​​proteinases ICP was studied in roots tomato plants resistant susceptible to root-knot nematode Meloidogyne incognita during infection under effects signaling molecules: salicylic (SA) jasmonic (JA) acids. It shown that, upon infection, are characterized by an increased accumulation transcripts at stages pene...

Greenhouse tests were conducted to determine the effects of two kinds of Meloidogyne hapla inoculum on the growth and quality of carrot roots, and the protection afforded in each case by nonfumigant nematicides in organic soils. For all treatments the percentage of carrots damaged was greater with larvae alone as inoculum than with larvae and eggs, indicating that most of the damage occurs earl...

Two experiments were conducted over 2 years in commercial potato fields in Shropshire, UK, to evaluate the compatibility of the nematicide aldicarb with commercial inocula of arbuscular mycorrhizal fungi (AMF) in the control of the potato cyst nematode Globodera pallida. The AMF used were Vaminoc (mixed-AMF inoculum), Glomus intraradices (BioRize BB-E) and G. mosseae (isolate BEG 12). In the ab...

Arbuscular mycorrhizal fungal (AMF) communities were established in pots using fungal isolates from a single field in Switzerland. It was tested whether multispecies mixtures provided more phosphorus and supported greater plant growth than single AMF species. Two host plants, medic (Medicago truncatula) and leek (Allium porrum), were inoculated with three AMF species (Glomus mosseae, G. claroid...
