Other claims from this paper (19)
- Observation Aeciospore production occurred from mid May to late August.
- Observation The peak aeciospore production period was between late May and mid June.
- Observation An average aecium produced spores for 35-50 days.
- Observation Individual cankers produced spores for up to 95 days.
- Association Biological factors reduced potential aeciospore production by 50-55% in any year.
- Observation Rodent damage was recorded on 40-52% of cankers.
- Observation Insect damage was recorded on 39-46% of cankers.
- Observation Tuberculina and Cladosporium infection was recorded on 17-33% of cankers.
- Observation Resinosis was recorded on 67-71% of cankers.
- Association Penicillium spp. played a lesser role than Tuberculina in reducing aeciospore production.
- Observation One hundred and seventeen species of insects, mites and spiders were associated with the rust canker.
- Observation Epuraea obliquus and Paracacoxenus guttatus were true mycetobionts of the rust canker.
- Observation Aeciospores were normally dispersed between 0800 and 1900 hours.
- Observation Turbulent atmospheric conditions were associated with all peak aeciospore concentrations.
- Association Heavy rains initially increased aeciospore concentrations.
- Observation Aeciospore deposition concentrations were very steep close to the source.
- Observation Aeciospores had an average velocity of 3.23 cm/sec in calm air.
- Observation Aeciospores germinated over the temperature range 1-30°C, with optimum close to 15°C.
- Observation Most aeciospores germinated within 4-5 hours.
