Investigations on chemical thinning of peaches by use of blossom and post blossom sprays have been in progress since the last decade mainly in the United States, Canada, and some European countries. Horticulturists are attempting to find new means to minimize the expense of hand thinning. The high cost of the hand thinning operation has caused many growers to underestimate the importance of this practice, and as a result their orchards have fallen into the biennial bearing habit. In addition, the fruit from un-thinned orchards was not acceptable on the market since it was small in size, lacked color, and often was infected with insects and diseases because of its hanging in close clusters on the trees.
