Abstract : Malformation was transmitted by sap-inoculation, but not by grafting or budding, indicating the involvement of a virus as a causal agent of malformation. Leaves from malformed shoots had lower chlorophyll a and b, and N contents, but higher carbohydrate, P and K contents than healthy material. Application of gibberellic acid (50 p.p.m.) to mango shoots in Oct.-Nov. halved malformation incidence and increased leaf area of the subsequent flush. NAA (200 p.p.m.), Metasystox [demeton-methyl] acaricide (0.05%), Blitox [copper oxychloride] fungicide (0.3%) and urea (1%) had no effect.
