Abstract : The effect of a single foliar spray of cobalt sulfate (500 or 1000 mg/litre), ascorbic acid (500 or 1000 mg/litre), or potassium metabisulfite (300 or 600 mg/litre), as well as trunk injections of Metidation (5 ml/m2 canopy, applied twice) or phosphoric acid (2 g/m2 canopy, applied two or four times) on the witches' broom disease (caused by F. subglutinans) and fruit yield of mango cv. Tommy Atkins were evaluated. Neither foliar spray nor trunk-injected treatments affected the proportion of malformed inflorescences or fruit yield. Trunk injected with phosphoric acid decreased the eriophyd mite (Aceria mangiferae) populations in mango buds. However, this was not related with the decrease in malformed inflorescences.
