efficiency of pleurotus ostreatus and p. sajor-caju as biocontrol agents of the root knot nematode, meloidogyne javanica, was evaluated in vitro and in greenhouse experiments. population of the nematode were prepared and nematicidal effects of culture filtrates of the fungal specieson second stage juveniles of m. javanica were tested. substrates completely colonized by tested fungi as fungal in...

Like any other branch of Agricultural Sciences, the Division of Nematology at IARI, initiated researches in the exciting field of biochemistry and molecular biology of plant parasitic nematodes during the early seventies of last century. The main research areas were biochemical mechanism of resistance against phytonematodes and diagnostics of economically important plant parasitic nematodes. Sp...

Pulsatilla koreana, a species endemic to Korea, is an important herb used in traditional medicine to treat amoebic dysentery and malaria. In the present study, 23 oleanane-type triterpenoid saponins 1-23 and eight lupane-type triterpenoid saponins 24-31 were isolated from the roots of P. koreana. Their structures were elucidated on the basis of spectroscopic data. The methanol extract and isola...

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,...

Plant parasitic nematodes which are highly successful parasites evolved a very specialized feeding relationship with the host plant to cause the destructive root-knot disease. They initiate their parasitic relationship with the host by releasing their secretions into root cells which in turn stimulate the root cells of the host to become specialized feeding cells which are considered as the sin...

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...

Biocontrol traits of arbuscular mycorrhizal fungi (AMF), in terms of single and mixed species inoculum, against the root knot nematode Meloidogyne incongita in Impatiens balsamina L., were examined with and without mineral fertilization in a greenhouse pot experiment. At harvest, 60 days after sowing, general plant growth parameters and plant defense response in terms of antioxidant activity an...

Certain nematicidal treatments for the control of root knot of tobacco in six field experiments in North Carolina were used to determine early, midseason, and postharvest densities of eggs and larvae of Meloidogyne spp., postharvest root-knot indices, and crop yield and value. Various statistical correlations showed that population densities determined 6-8 wk after transplanting were more indic...
