Effects of Ethephon and Gibberellic Acid on Thinning Peaches1

Year: 1979

Type: article

Abstract: Fruit retention on several cultivars of peach ( Prunus persica (L.) Batsch) was reduced when (2-chloroethyl phosphonic acid (ethephon) at 37.5 to 150 ppm was applied during fruit stage I and the beginning of stage II. Leaf yellowing and early drop as well as gummosis of branches and fruits frequently occurred as side effects. Simultaneous application of gibberellic acid (GA 3 ) at 50 to 100 ppm significantly reduced or eliminated the undesirable side effects of ethephon without altering the thinning response.
