Abstract

In the present investigation, the effect of soil depth, moisture and temperature on sclerotium survival and germination of Sclerotinia sclerotionlln and the rate of SUNFLOWER infection were studied. Sclerotia needed for experimental purposes were obtained on mixed wheat kernel and carrot pieces. Mature sclerotia were placed0, 2, 5, 8, 11, 14, 16 and 20 cm deep in soil in plastic pots with and or without host plant. It was revealed that sclerotia embedded at lower depth of soil up to 5 cm showed high percent of 0, 2 and 5 cm. Results on the effect of soil moisture indicated that, the most suitable condition required for sclerotium germination was at 24% moisture content of soil. This was achieved by watering of pots every other day. Lower or higher ranges of soil moisture resultedin lower percent germination. Average temperature of soil (5-10cm in depth) during growing season of SUNFLOWER in rain-fed area measured above 30°C.Due to low soil moisture and high temperature. Sclerotia are presumed to remained ungerminated in the soil. In order to manage the disease, it is recommended that cultivation of SUNFLOWER in West-Azarbaidjan to be established in rainfed areas.
