Restoration of Normal Growth in Vegetatively Malformed “Kent” Mango (Mangifera indica L) Cultivar

Abstract

The aim to restore normal growth in one year field grown trees
of “Kent” mango cultivar suffering symptoms of vegetative
malformation. Single and combined foliar treatments of the growth
regulators, BA, NAA, and GA3 were tested following a comprehensive
treatment composed of pruning malformed branches 5 cm below the
infected area, spraying with stroby (fungicide-acaricide), and fertilization
with 100 g urea/ tree. Symptoms of malformation were not detected 6 and
12 months after the treatment, even in control trees, suggesting the
adequacy of the comprehensive treatment of spaying with stroby
(fungicide – acaricide) and urea fertilization for the control of vegetative
malformation. However, single application of either GA3 or NAA
enhanced growth significantly.
