Fruit drop before reaching technological maturity is one of the core problems in the apple industry. The aim of this paper is to examine the effect of the chemicals VBC 30033 based on aminoethoxyvinylglycine (AVG) and Dirager based on α-naphtalenacetic acid on the prevention of fruit drop of apple cultivar Idared, as affected by the time of application, the number of applications and the concentration. The research was conducted from 2009 to 2011 at the experimental field of the Faculty of Agriculture in Novi Sad. The special focus was placed on the double and triple applications of NAA which were considered the most effective in preventing fruit drop. The triple application of NAA 5 ppm and NAA 10 ppm showed equal effectiveness, therefore the treatment NAA 5 ppm is recommended due to the reduced use of the chemical
