the present study examined the effects of mycorrhizal fungus glomus sp. on pistachio growth parameters and root-rot disease of pistachio seedlings under greenhouse conditions. the experiment was conducted in factorial arrangement based on completely randomized design with six replications. examined factors included: levels of glomus inoculation (with (m1) and without inoculation (m0) and two le...

The spin-energy E rot of a Kerr black hole surrounded by a torus may power emissions in multiple windows. The recently determined true GRB-energy E γ = 3 − 5 × 10 50 erg indicates a minor fraction E j /E rot ≃ 0.1% in baryon poor output, here considered as jets along open magnetic flux-tubes from the horizon to infinity. A major fraction E gw /E rot ≃ 5% is expected in gravitational radiation f...

fusarium solani wasisolated from diseased roots of common bean (phaseolus vulgaris) grown in fields which were severely infected with fusarium root rot of bean in markazi province of iran. specific pcr primer pairs were used for the identification and verification of f. solani (mart.) f.sp. phaseoli (burkholder) w.c. snyder and n.h. hans. spore suspensions of f. solani f.sp. phaseoli were subje...

Leaf spot disease of rough lemon and brown spot disease of tangerines caused by distinct pathotypes of Alternaria alternata, and postharvest fruit black rot disease caused by A. citri, are the three major fungal diseases of citrus. The pathogenicity and specificity for the pathogens of Alternaria leaf spot and brown spot diseases are associated with the production of different host-specific tox...

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...

While fungicides may be a major mechanism for control of avocado root rot, integrated management requires several other non-fungicidal approaches which are used together to maximize root rot control. Non-fungicidal methods of control include planting clean avocado nursery stock, selecting low hazard sites, planting on mounds in more hazardous sites, preventing the introduction of P. cinnamomi, ...
