Controlling premature fruit drop of cultivar Idared by using α-naphthaleneacetic acid
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
