Fusarium oxysporum f.sp.radicis-licopersici (Forl) is a soilborne pathogenic fungus which can cause tomato foot and root rot (TFRR). Tomato root exudate is a good source of nutrients for both Forl and the TFRR-suppressing biocontrol bacterium Pseudomonas fluorescens strain WCS365. Incubation of Forl microconidia in tomato root exudate stimulates their germination. This phenomenon is observed, t...
for determination the host range of fusarium stem and root rot of green-house cucumber (cucumis sativus) that caused by fusarium oxysporum f. sp. radicis-cucumerinum, after isolation, identification and study of pathogenisity, 16 species of several plant families were artificially inoculated with this pathogen by sand and corn meal contaminated with pathogen, two varieties of cucumis melo, of c...
Laboratories use pigmentation, antibiotic susceptibility, and biochemical tests to identify anaerobic organisms that play a role in bovine interdigital necrobacillosis (bovine foot rot). In this study, 16S rRNA gene sequencing was used to identify strains to the species level that were originally classified as Prevotella or Porphyromonas spp by conventional phenotype assessment methods. Of 264 ...
Ovine foot rot caused by Dichelobacter nodosus is affecting sheep worldwide. The current diagnostic methods are difficult and cumbersome. Here, we present a competitive real-time PCR based on allelic discrimination of the protease genes aprV2 and aprB2. This method allows direct detection and differentiation of virulent and benign D. nodosus from interdigital skin swabs in a single test. Clinic...
this experiment was conducted for determining the effect of irrigation termination before harvesting and late application of nitrogen on sugar beet yield, quality and root rot during 1993-95 at safiabad agricultural research center. different irrigation termination and late nitrogen application treatments had a significant effect on root yield. terminating irrigation 1 and 3 weeks before harves...
Rhizoctonia oryzae causes root rot and stunting of wheat, barley, and other small grains, and is widely distributed in eastern Washington State. The spatial distribution of both the pathogen and the disease were studied over two seasons in a 36-ha field north of Pullman, Wash. The field was direct seeded with spring barley in 2000, then divided and planted to winter wheat and spring wheat in 20...
Diseases caused by root rots figure prominently amongst the most-studied pathologies of forest trees. Indeed, root and butt rots cause more economic damage to commercial forestry in the temperate world than any other known type of disease. While this notoriety underlines the negative impact of this type of disease on timber production, a much more dynamic and positive role can be assigned to ro...
The effect of mineral fertilization (NPK), foliar with micronutrients (Cu, Zn and Mn) the NanoGro biostimulant on severity leaf, spike, stem base root diseases in winter spelt cv. Schwabenkorn was evaluated a field-plot experiment. A mycological analysis performed content Fusarium mycotoxins grain determined. Mineral exerted varied effects Septoria leaf blotch glume blotch, they promoted spread...
