Other claims from this paper (10)
- Observation Pink rot symptoms occurred in 15 (32%) infected-tuber samples in 1999.
- Observation Pink rot symptoms occurred in 2 (8%) samples in 2000.
- Observation Pink rot symptoms occurred in 2 (50%) samples in 2001.
- Observation All P.E.I. field and single-zoospore isolates were highly sensitive to mefenoxam, with EC50 below 0.5 µg mefenoxam/mL.
- Observation Maine tester isolates ranged from sensitive to highly resistant to mefenoxam.
- Intervention effect Isolates inhibited on mefenoxam agar were suppressed in tubers from foliar treated plants.
- Intervention effect Two foliar applications sometimes reduced disease incidence and severity more than one application.
- Observation Moderately or highly resistant Maine isolates infected treated potato tubers.
- Association Pink rot suppression was greater in Kennebec than Russet Burbank.
- Association Mefenoxam efficacy was reduced in drier years.
