Strawberry Root Rot and the Recovery of Pythium and Rhizoctonia Spp

One root disease complex often associated with strawberry plants grown in nonfumigated soil is referred to as black root rot. While not currently a widespread problem in properly fumigated commercial production fields, with the impending phase out of the use of methyl bromide and alteration of current fumigation practices this disease complex may once again become a problem. In other strawberry...

Field screening of safflower genotypes for resistance to charcoal rot disease

Nineteen safflower genotypes (Carthamus tinctorius L.) that originated from different geographical regions were screening for their response to infection with Macrophomina phaseolina, the charcoal rot pathogen at the research farm of Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran, in 2005. The plants were evaluated for length and width of necrotic lesion at the e...

Evaluation of Drought Tolerance Indices for Selection of Superior Genotypes in Black Cumin (Nigella sativa L.)

Drought stress is considered as one of the most important constraints to the crop production, including medicinal plants in many arid and semi-arid regions. This study was carried out to determine the most effective indices for drought tolerance and identification of tolerance genotypes under drought conditions in N. sativa. For this purpose, 36 genotypes of N. sativa were tested as a split plo...
