Other claims from this paper (6)
- Observation The mean baseline propiconazole EC50 of P. digitatum from untreated orchards was 0.10 mg/liter (range 0.04 to 0.27).
- Observation After 3 years of postharvest fungicide use, 22.2% of P. digitatum isolates recovered were propiconazole-resistant.
- Observation Only one packhouse harbored propiconazole-resistant G. citri-aurantii isolates.
- Observation The resistant G. citri-aurantii isolate caused a higher mean sour rot incidence (24.8%) than the sensitive isolate (7.0%) at the registered propiconazole concentration.
- Observation A moderately sensitive P. digitatum isolate (EC50 = 0.147 mg/liter) resulted in 17.0% green mold incidence.
- Recommendation The development of fungicide resistance should be monitored so that resistance management strategies are in place.
