PCR-Based Test for Differentiating Varieties of <i>Gaeumannomyces graminis</i>, The Take-All Pathogens
… of wheat worldwide. The causal agent is <I>Gaeumannomyces</I> <I>graminis</I> (Sacc.) Arx & Olivier. Based on morphological characteristics and host ranges, three varieties of <I>G</I>. <I>graminis</I> have been recognized. <I>G</I>. <I>graminis</I> var. <I>tritici</I> Walker (Ggt) is the …

Evaluation of Agents for the Suppression of Take-all of Wheat in Virginia in Greenhouse and Field Studies, and Characterization of Isolates of Gaeumannomyces graminis varieties
Take-all of wheat, caused by Gaeumannomyces graminis var. tritici (Ggt ) is a problem wherever wheat is grown. Crop rotation is currently the only method for control. Our objectives were to develop a greenhouse bioassay and to evaluate the efficacy of mineral, chemical, and or biological agents for …

A comparative study of certain soil-borne cereal pathogens with reference to carbohydrate utilisation and polysaccharide hydrolysis
Cochliobolus sativus, Fusarium culmorum and Gaeumannomyces graminis var tritici isolates produced pectin degrading enzymes, xylanase and carboxymethylcellulase when grown in a salts medium with an appropriate carbon source. There was little difference in the amounts of enzymes produced by the …

Take-all in Wheat: PCR Identification of the Pathogen and the Interactions Amongst Potential Biological Control Agents
<i>Gaeumannomyces graminis var. triciti (Ggt)</i>, the causal agent of take-all in wheat, is difficult to detect accurately and rapidly due to its similarity to fungi in the Gaeumannomyces-Phialophora complex. My objectives are to detect the fungus in infested plants and soil, and to predict …

Using Modelling to Optimise the Use of Biological Control Agents Against Soil-Borne Plant Pathogens
… on modelling the infection of winter wheat by Gaeumannomyces graminis var. tritici and suppression by the biocontrol agent 2,4-DAPG fluorescent Pseudomonas spp. Parameter values are obtained for the model through fitting it to data from this system. Application timing and amount of application …

Root Rot Pathogens of Wheat in South Dakota and Their Affect on Seed Germination and Seedling Blight in Spring Wheat Cultivars
… from eight root samples. The fungus <em>Gaeumannomyces graminis tritici</em> associated with Take-all was not recovered from the collected samples in both years. Further, we studied the effect of <em>B. sorokiniana</em> and<em> F. graminearum</em> infested seed on germination and seedling …
