Abstract: The problem of fruit drop is a big issue in water apple fruit. Premature bud and fruit drop is a serious problem in water apple production and quality. Growth regulators, hydrogen peroxide and phloemic stress are important tools to improve the quality and reduced the pre-harvest fruit drop of water apple. Growth regulators, hydrogen peroxide and phloemic stress are important tools to improve the quality and reduced the pre-harvest fruit drop of water apple. During the early growth stages, excessive fruit drop is caused by cultural and environmental factors that affect pollination, flower fertilization and fruit set. The role of PGR acts as a messenger and required only in small amount at low concentration to regulate the flowering and other developmental process. Two type of chemical with two different concentrations were used in this experiment, one is 2,4-D 5mg/l and 10mg/l and the another one is NAA 5mg/l and 10mg/l. This study was conducted with the aim to determine bud and fruit dropping and of water apple fruit and to find the better remedies to minimize those losses. It was observed from the study that, growth regulators had significant effect to reduce dropping in water apple fruit and 2,4-D causes minimum losses as compared to NAA. This study will be very beneficial for water apple fruit growers.
