The invention relates to the use of gibberellin 7 (GA7) for thinning of stone fruit, wherein the use comprises applying the GA7 to stone fruit in a first year by foliar spray within 12 weeks after full bloom, to achieve thinning in the following year. The stone fruit can be peach, nectarine, apricot, cherry, mirabelle or plum, preferably peach or nectarine. GA7 is used or applied in the period of 4 to 12 weeks after full bloom in the first year. The GA7, if used in admixture with GA4, has relative amounts of GA7 to GA4 of 70% GA7 or more and 30% GA4 or less. |
