Tree fruit typically set an excessive number of fruit, and blossom or fruit thinning is required to ensure that the remaining fruit attain marketable size. The conventional method for adjusting crop load in peach and nectarine orchards is to
Growers are finding it increasingly difficult to find a workforce to manually thin fruit crops, and the cost of farm labor is increasing. Glozer and Hasey (2006) estimated that hand thinning labor represented 31% of all cultural costs associated
fixed intervals without considering the actual location of plants. When the stand before thinning was not uniform and plants were removed between set spacing, this resulted in large gaps in the rows ( Siemens et al., 2012 ). For selective thinners
It is well established that peach ( Prunus persica L. Batsch) requires some form of thinning early in the growing season to produce a crop of marketable size fruit ( Byers et al., 2003 ; Havis, 1962 ; Tukey and Einset, 1938 ). Early studies by

2015, the total area of mandarins planted in South Africa increased by 21% from 6401 to 7722 ha, more than any other group of cultivars. Mandarin fruit generally colors well, have excellent taste, exhibit little or no seeds, and have thin rinds that are

vivipary can occur when green shucks fail to dehisce, and is often associated with high humidity between the shell and shuck and high air temperatures during ripening ( Sparks et al., 1995 ). Mechanical fruit thinning has been used as a tool to minimize the
