Abstract: A planned study was conducted to assess the prevalence incidence and intensity of different decline disorders prevailing in mango growing areas of the Punjab, Pakistan. Sixteen locations were visited in four districts of the Punjab with the objective to confirm the status and update the existing statistics for future management and planning. Four disorders viz. twig blight, tip dieback, gummosis and bark cracking/ splitting were noted with 55.0, 50.0, 25.0 and 25.0 % prevalence, respectively. Incidence percentage in the same order was 3.17, 4.43, 0.62 and 1.25 % while intensity ranged from 16.0-50.0 %. Maximum intensity of 5.17 % for quick decline was noted in Sahiwal district. Chaunsa proved to be the most susceptible cultivar with 6.95 and 3.14 % incidence and intensity, respectively.  Prevalence of the decline syndromes in the mango orchards suggests to devise an integrated strategy to combat the problem in future.
