Resumo: The effectiveness of 6-benzyladenine (6-BA, 150 mg/L), 1-naphthaleneacetic acid + 6- benzyladenine (ANA 10 mg/L + 6-BA 100 mg/L) and metamitron (165; 165+165; 247.5 mg/L) were analyzed in 6 years old apple ‘Fuji’ grafted on M7, considering simple, double or combined applications. Production per hectare, average fruit weight and commercial fruit production were not significantly different between the different methods however, there were significant differences between these treatments when considering the highest fruit size class. All the chemical thinning methods led to a reduction in the total number of fruits/BSA (cm2) and in the average number of fruits/100 fruit clusters. The methods ANA+6-BA and metamitron at 247.5 mg/L showed highest efficiency and metamitron at 247.5 mg/L resulted in the best global results: average fruit weight of 175.6 g and average diameter of 77 mm. The lower efficiency of 6-BA at 150 mg/L was due probably to adverse weather conditions that occurred 2-3 days after the product application. Chemical thinning is more favorable than manual thinning due to excessive cost of the second and to the lack of available labour.
