Development of Pythium oligandrum drechsler for biological control of fungal soil-borne diseases.
… developed for bulk production of P. oligandrum oospores. A liquid cane molasses medium was particularly convenient and efficient. A range of formulations were prepared using oospores produced mainly in this medium. Formulations were evaluated against pathogens causing damping-off in cress and …

Épidémiologie comparative des deux clades de Plasmopara viticola (clades riparia et aestivalis) prévalents dans l’est du Canada
… Pour finir, la maturation et la germination des oospores des deux clades ont été comparées. Cette étude a montré que la germination des oospores des deux clades avait lieu durant toute la saison et que cette germination avait un patron bimodal. En effet, la fréquence de germination des oospores …

Diagnostics and epidemiology of <i>Phytophthora infestans</i> : the cause of late blight of potato
… The primer pair can also detect as few as two oospores, two sporangia and four zoospores of <i>P. infestans</i>. Using primer pair INF FW2 and INF REV, ten oospores of <i>P. infestans</i> could be detected in 0.5 g soil, besides detecting the pathogen in symptomatic and symptomless leaves, …

Optimizing in-vitro production of Delaware-isolated Pythium zoospores
… in various ecological niches by producing oospores, sporangia, and mycelial hyphae. However, infections on host tissue are primarily initiated by specialized, motile, asexual structures known as zoospores released from sporangia. Research focused on Pythium-plant interactions is advanced by …

Effectiveness of mustard short-cycle cover crops for management of Phytophthora capsici and Fusarium spp. in cucurbits
… significantly reduced germination of P. capsici oospores compared to that of control treatment. None of the mustard extracts significantly affected zoospore germination of any of the isolates of P. capsici. The FBL+Tilney and Tilney extracts significantly reduced colony growth of F-3 isolate of …

Initial Fine Mapping of the Spinach Downy Mildew Resistance Locus RPF1
… either as mycelium in seed or as dormant oospores (Inaba and Morinaka, 1984; Inaba et al., 1983).</p> <p>Very few studies have been published on the genetics of resistance to <em>Pfs </em>. However, several more recent studies on the genetics of resistance have been conducted and it has …

A potential energy-saving heat treatment for re-circulated irrigation water and its biological mechanisms
… were performed to determine the survival of zoospores and chlamydospores of P. nicotianae, and oospores of P. pini as well as seven bacterial species after heat treatments at given periods of time. Greenhouse experiments were conducted to determine the applicability of the lab assay data to …
