Frozen hydrated specimens of Pratylenchus agilis and dauer larvae of Steinernema carpocapsae were observed with low-temperature field emission scanning electron microscopy. This new technique provides information about the surface features of nematodes and also allows specimens to be fractured to reveal their internal structure. Furthermore, both halves of fractured specimens can be retained, e...

Çalışmada Türkiye’nin Isparta ve Burdur illerinden izole edilen on iki Fusarium culmorum (W. G. Sm.) Sacc. izolatı ile Pratylenchus thornei (Sher and Allen),1953 etkileşimi İkizce buğday çeşidinde kontrollü koşullar altında (25±2°C %60±5 nem) araştırılmıştır. Buğdaylarda ilk kardeş yapraklar oluştuktan sonra deneme kurulmuş 4 uygulamada denemeler yapılmıştır. Uygulamalar; sadece P. uygulaması (...

Root-lesion disease, which is caused by Pratylenchus loosi , is one of the most important diseases currently impacting Iran tea plantations. This disease causes great economic crop impacts. Northern provinces, which supply much of Iran’s tea production, have been especially hard impact by root-lesion disease.The purpose of this study was to biological control the nematodes as one of the main se...

Four populations of the lesion nematode Pratylenchus brachyurus were tested in a greenhouse on seven selected plant species to determine host suitability and usefulness in identifying physiological races of the nematode. The differential plants were 'Florida 77' alfalfa, 'Harvester' snap bean, 'Rough Lemon' citrus, 'Pioneer 304C' corn, 'Florunner' peanut, 'Braxton' soybean, and 'Rutgers' tomato...

Growth of alfalfa (Medicago sativa cv. Vernal) seedlings was compared after inoculation with combinations of either Pratylenchus penetrans and Fusarium soloni or P. penetrans and F. oxysporum f. sp. medicaginis. A synergistic disease interaction occurred in alfalfa when F. oxysporum and P. penetrans were added simultaneously to the soil. Alfalfa growth was suppressed at all inoculum levels of P...

The fungus Gnomonia comari, causal agent of strawberry leaf blotch, was inoculated at the crown of young axenized strawberry plants growing in sterilized sand. Only the roots were colonized, and the infection was symptomless. When the fungus colonized the roots in the presence of the root lesion nematode Pratylenchus penetrans, the plants were extremely stunted and their root system was necroti...
