Using early fruit control to adjust the fruit volume to 2 to 3 times the final fruit quantity requires more time for picking flowers than do conventional methods. However, it can work in a dispersed manner at a relatively small margin from the dormant period to the beginning of flowering. Early fruit control is an extremely effective way to reduce labor by drastically reducing the total work time of fruit control. The total working time for fruit control, from picking buds to mature fruit, can be reduced by about 50%, as compared with conventional ways of adjusting fruits. Although there is a difference in the hypertrophic effect depending on the cultivar, when early fruit control is carried out, increased fruit weight in all four varieties can be confirmed. Fruit quality, such as sugar content and coloration, has no effect of early fruit control. It has little influence on deformation and nuclear crack generation. From this fact, it is expected that the technique for the early fruit control of peaches is highly effective at saving labor during actual cultivation, and it can be expected to be widespread as a management method effective for large-scale production.
