Abstract
As part of the ISAFRUIT project we conducted three years of thinning trials using environmental friendly compounds that potentially may be registered and allowed for organic fruit production. In the first year four different compounds were tested; two clay compounds, NaCl (kitchen salt) and lime sulphur. In the second year the number of compounds was reduced to the three compounds that had showed potential as thinners in the first year and finally in the last year focus was solely on NaCl. Based on three years experiments we conclude that NaCl is a potential thinner of Elstar which is normally regarded as hard-to-thin variety. Multiple applications, however, may lead to over-thinning. Thinning with NaCl improved return bloom significantly and to an extent that levels out biennial bearing. NaCl application caused moderate to severe leaf damage, but no russet on the fruits. NaCl is a cheap, efficient and environmentally friendly compound (in the dosages used – which is equivalent to brackish water) that is capable of thinning even difficult and biennial apple varieties.
