FUNGICIDE INJECTION, AN EFFICIENT MANAGEMENT TECHNIQUE OF MANGO SUDDEN DEATH DISEASE IN PUNJAB, PAKISTAN

Abstract

Mango sudden death disease is known to be a very destructive disease for mango orchards. In this study, we applied two fungicides namely Topsin M and Aliette at the rate of 75 g L^-1 and 150 g L^-1 to infected tree trunks through injection method, three times at an interval of 10 days. The disease severity significantly decreased from 18.7% to 7.10% (57% reduction) in year 2007 while from 21.42% to 14.82% (35% reduction) in year 2008. There was also a significant difference in number of fruits of treated (952 fruits per tree) and untreated trees (776 fruits per tree). There is further need to explore other systemic fungicides and their compatibility with other existing integrated management practices for a sustainable management package.
