The mycelial growth, sclerotial production, and carbon utilization of the snow mould biocontrol agent Typhula phacorrhiza Fries were compared with the two grey snow mould fungi, Typhula ishikariensis Imai and Typhula incarnata Lasch ex Fries. Variation was observed among the four isolates for each species, but there was greater variation among species. All three species were able to grow at the...

Three kinds of sclerotia of Typhula spp. from Ardabil, East Azerbaijan and Qazvin Provinces in the northwest of Iran were collected. Morphology and ITS sequences of rDNA suggested that the collected fungi belonged to Typhula incarnata Lasch, Typhula phacorrhiza (Reichardt) Fr. and Typhula sp. These three taxa are new records in the Middle East and the result of this research suggests that Iran ...

Two field tests and one lab test were conducted to examine the environmental factors affecting sporophore production in Typhula phacorrhiza and to compare these results with those documented for T. ishikariensis and T. incarnata. In the 2001 lab test where lighting, soil moisture, and soil-sand media were tested in 50 mL screw-cap tubes incubated at 4 degrees C, the limiting factor for Typhula ...

An isolate of the fungus Typhula phacorrhiza (Reich:Fr.) Fr. was evaluated in field tests across Canada for suppression of winter injury which was rated based on combined abiotic and biotic symptoms after snowmelt. This isolate, TP94671, has been identified in previous tests as being suppressive to gray snow mold, and a specific purpose of these trials was to evaluate the effect on pink snow mo...

Isolates of the fungus Typhula phacorrhiza Fries (TP) were evaluated in field tests over a 3-year period for suppression of grey snow mould caused by Typhula ishikariensis Imai (Tish) and Typhula incarnata Lasch ex Fr. (Tinc). Isolates of TP were collected across southern Ontario in the spring of 1994. In December 1994, 46 of these isolates, which had been cultured on mixed grains, were applied...
