However, there are several 3 factors on successful thinning application. Firstly application concentration and application time should be regulated in the best way. Tree age and vigor, variety and climatic conditions especially, temperature and humidity is to be quite important. On the other hand all world recently, it has become a pressure for using environmentaly friendly chemicals. Keywords : Apple (Malus communis L.), Chemical Thinning
