systemic induction of peroxidase and polyphenoloxidase in tomato roots and stem followed by application of split root system method was investigated. root system of tomato seedling in the sixth growth stage were divided in two equal sections after washing and replanted in two adjacent pots and then inoculated with nematode and fungus as fallowing treatments. the second treatment was inoculation...

Pines responded to inoculation with Bursaphelenchus xylophilus by changes in reducing and nonreducing carbohydrate concentrations dependent on the pine species and the pathotype of B. xylophilus with which the trees were inoculated. Carbohydrate concentrations, in compatible pine-nematode pathotype combinations, decreased initially after inoculation and then increased slightly before decreasing...

ABSTRACT Nematode control strategies are limited and alternative is demanded. The main aim was to evaluate potential of Hohenbuehelia spp. (Hohenbuehelia mastrucata, barbatula, bullulifera, portegna, petaloides paraguayensis) Trichoderma koningiopsis against Meloidogyne javanica in bean plants greenhouse. parameters evaluated were the number galls egg masses which three root regions: basal, int...

In recent years, continuing environmental problems associated with the use of nematicides (47) have introduced a sense of urgency into the search for alternative methods of nematode management. For the past 90 years, research on the biological control of nematodes with microbial agents has been done by a few dedicated nematologists who have worked in small groups with little support. About 10 y...

the soybean cyst nematode (heterodera glycine ichinohe, scn) is one of the most serious yields limiting pathogen on soybean (glycine max (l.) merr) which is found in many soybean–growing regions throughout the world. applying of resistant sources is one of the efficient measures to manage this nematode. in this study, reaction of 63 soybean lines to the soybean cyst nematode were evaluated in f...

The effect of a contplex of several insect and nematode pests on yield of yellow squash (Cucurbita pepo L.) was examined in two field tests in southern Florida. Applications of permethrin for insect control and oxamyl primarily for nematode control plus some insect control were made alone and in combination to achieve differential reduction of various insect and nematode components contributing...
