Other claims from this paper (9)
- Observation The Sirococcus fungus survived temperatures of −10 °C for several weeks.
- Observation Temperatures of 35 °C were lethal to Sirococcus spores and mycelium.
- Intervention effect Light did not measurably affect Sirococcus conidial germination and mycelial growth.
- Observation Sirococcus infection of black spruce seedlings occurred when inoculated seedlings were enclosed in plastic bags for at least 1 day.
- Intervention effect Sirococcus infection was greatest under a daily temperature cycle of 16–21 °C, compared with 10–16 °C.
- Intervention effect Sirococcus infection was significantly reduced at 24–30 °C.
- Intervention effect Sirococcus infection percentage was greater under low light intensities (900–3900 lx) than under high light intensities (4300 – 10 000 lx).
- Recommendation The authors recommend protective measures only if cool, wet and cloudy weather persists during summer.
- Observation Warm sunny weather during the period of susceptibility would probably control Sirococcus shoot blight.
