550 A Naturally Occurring Compound for Controlling Powdery Mildew of Greenhouse Roses

Infestation of Transgenic Powdery Mildew-Resistant Wheat by Naturally Occurring Insect Herbivores under Different Environmental Conditions

A concern associated with the growing of genetically modified (GM) crops is that they could adversely affect non-target organisms. We assessed the impact of several transgenic powdery mildew-resistant spring wheat lines on insect herbivores. The GM lines carried either the Pm3b gene from hexaploid wheat, which confers race-specific resistance to powdery mildew, or the less specific anti-fungal ...

Naturally occurring broad-spectrum powdery mildew resistance in a Central American tomato accession is caused by loss of mlo function.

The resistant cherry tomato (Solanum lycopersicum var. cerasiforme) line LC-95, derived from an accession collected in Ecuador, harbors a natural allele (ol-2) that confers broad-spectrum and recessively inherited resistance to powdery mildew (Oidium neolycopersici). As both the genetic and phytopathological characteristics of ol-2-mediated resistance are reminiscent of powdery mildew immunity ...

comparison of a new fungicide (opus) with common fungicides in controlling powdery mildew of sugar beet

in this study, recently produced fungicide opus was compared with current fungicides dinocap, sulfur and calyxin for controlling powdery mildew disease of sugar beet in completely randomized block field experiments conducted in kermanshah and west azarbaijan provinces. fungicides were applied according to the recommended field dosages. there were five treatments (four fungicides plus a water-sp...

determination of spraying turns by tridimorph fungicides for controlling of powdery mildew disease in sugar beat

powdery mildew disease caused quality and quantity losses of sugar beet production. therefore, five spraying treatments and three sugar beet variety were conducted in split plot design with four reapplications during consecutive two years in kermanshah and mashhad regions. in order to control of disease, tridimorph fungicide was used. spraying treatments were in main plot and variety in the sub...
