Summary
Potato seed pieces bearing one sprout were inoculated with cultures ofRhizoctonia solani, planted in pots of compost at 45, 60, 75 or 90% water holding capacity (whc) and incubated at 5, 10 or 15 °C. Shoots emerged after 2–3 wk at 15°C, 3–4 wk at 10 °C and after 9–11 wk at 5 °C and stem canker recorded after emergence, was severe at 10 and 15 °C but slight at 5 °C. Soil moisture had less effect on emergence but stem canker was more severe in dry (45 % whc) than moist soils (75 and 90 % whc). The relationship between time of shoot emergence and stem canker severity is discussed.
