Glomerella leaf spot (GLS) is an apple disease difficult to control, even with the use of chemical
fungicides. In years of GLS high pressure, protective fungicides in the chemical group of
dithiocarbamates, especially mancozeb, have been used frequently, and even so, the control has not
been satisfactory. Because of this scenario, growers have been increasing the frequency of application
and the dose recommended on the product label, a situation that will become unsustainable over the
years, and resistance of some species belonging to Colletotrichum acutatum species complex to
mancozeb has already been observed in Brazil. Our objective was to verify the efficiency of several
chemicals? fungicides in the control of GLS in field conditions in three consecutive crop seasons.
The experiments were conducted at the Experimental Station of Caçador in 2017/2018, 2018/2019
and 2019/2020 crop seasons. The tested fungicides were: mancozeb, mancozeb + trifloxystrobin,
mancozeb + trifloxystrobin + tebuconazole, fluxapyroxad + pyraclostrobin, chlorothalonil, dithianon,
captan, metiram + pyraclostrobin, thiophanate-methyl + fluazinam, fluazinam, metiram, dodine,
folpet, and propineb. We assessed the GLS incidence over time, and with these data, the Area Under
the Disease Incidence Progress Curve (AUDIPC) and the control efficiency of each treatment were
calculated. The experimental design was in randomized blocks with four replications. The fungicides

an efficient control of GLS. The fungicide metiram + pyraclostrobin showed an intermediate control
and the fungicides dodine, and fluxapyroxad + pyraclostrobin were not efficient in GLS control. In
general, systemic fungicides were not efficient in GLS control. Protectant fungicides were the most
efficient in GSL control, being excellent options to be rotated with the fungicide mancozeb, which is
used as a standard in GLS control in Brazil. MenosGlomerella leaf spot (GLS) is an apple disease difficult to control, even with the use of chemical
