Globodera spp. eggs go through a diapause, which remains dormant until favorable hatching conditions are reached. Because of the regulatory concerns with cyst nematodes, it is often only possible to rear eggs for research in the greenhouse. However, hatch is often lower for greenhouse-produced eggs than for eggs obtained from...
Root rot of raspberry (Rubus idaeus), thought to be primarily caused
by Phytophthora rubi, is an economically important disease in the
western United States. The objectives of this study were to determine
which Phytophthora species are involved in root rot, examine the efficacy
of different isolation methods (cane, root, and...
Laboratory-based methods to test egg viability include staining with Meldola's Blue and/or juvenile (J2) hatching assays using potato root diffusate (PRD). These two methods have not been tested under identical conditions to directly compare their assessments of Globodera egg viability. Using two bioassay strategies, cysts from a Glabodera sp. population...
