Title: Apple Cultivar Sensitivity to Azoxystrobin Fungicide
Authors: R.M. Crassweller and D.E. Smith
Abstract:
Apple cultivar sensitivity to azoxystrobin fungicide was evaluated over two years.
A single application of azoxystrobin at 200 pprri concentration was applied to selected shoots of over fifty different apple
cultivars and rootstocks.
Treated shoots were then evaluated for phytotoxicity four to seven days later.
Cultivars that showed symptoms in one or both years included 'Braeburn', BC 8S-26-50, 'Gala', 'Gold-Rush', 'Hampshire', 'Jonamac', NY 75414-1, NY 65707-19, NY 75907-72, 'Silken', 'Spigold', 'Suncrisp'
and 'Zestar!' Of the rootstocks tested, only CG.179 and EMLA.26 exhibited phytotoxicity on
treated leaves.
Cultivars that were not injured by azoxystrobin in either year were 'Arlet', 'Carousel',
'Creston', 'Enterprise', 'Fortune', 'Fuji', 'Gala Supreme', 'Ginger Gold', 'Orin', 'Pristine', 'Rome
Beauty', 'Sansa', 'Shizuka', 'Yataka', and 'York Imperial'.
