Thinning efficacy of Brevis® and Exilis® on two different application days in 2017 in apple cultivar 'Nicoter'
Compared to other apple cultivars it is even more important in production of cultivar 'Nicoter' to avoid an excessive crop load, which results in a small fruit size and poor red colour formation and thus, in a low percentage of fruits that can be sold under the trademark name Kanzi®. Hence, fruit thinning is usually necessary to improve the profitability of this crop. In this trial, the efficacy of the thinning agents 6-benzyladenine (Exilis®) and metamitron (Brevis®) was evaluated in apple cultivar 'Nicoter' at two different application dates in May 2017. Exilis® was applied at 5.0 L ha‑1 orchard, Brevis® at 1.1 and 1.65 kg ha‑1 orchard. For both thinning agents, the best results were obtained with the late application. The strongest thinning was observed with 1.65 kg ha‑1 Brevis®.
