An Integrated Approach to Control Anthracnose of Guava (Psidium guajava)
T.H. Ansari, T. Yoshida and M.B Meah

Abstract:
The experiments were conducted to explore the possibility of integration of various approaches for control of guava anthracnose during fruiting seasons, 1992-93. The organic manures cowdung at 10 kg/tree, Mustard oil cake (MOC) (ghani), MOC (mill), Sesame oil cake (SOC) at 2 kg/tree and fertilizers urea, Tripple Super Phosphate (TSP), Muriate of Potash (MP), ZnSO4, Gypsum at 0.3, 0.3, 0.35, 0.005 and 0.01 kg/tree respectively were applied separately and in six combinations. In another experiment tilt, rovral, Mn, B and Zn at 1000, 500 and 2000 ppm respectively were sprayed separately for three times at 15 days interval starting from early fruit stage. All the sprayed plants received a recommended basal dose of NPK before start of spraying schedule. Disease severity (% fruit infection and % fruit area diseased) was recorded at 15 days interval for continuous 4 times starting 15 days after treatment. No disease developed for the treatment of cowdung, MOC (mill), MP, ZnSO4, Cowdung+MOC (mill), K+ZnSO4, NPK+tilt spray and NPK+Zn spray. Very slight infections were observed for rovral spray (0.08%), Mn spray (0.08%), NPK+ZnSO4+gypsum (0.18%), PK+ZnSO4 and MOC (ghani) (1.8%). TSP, cowdung+MOC (ghani) were less effective but urea, gypsum, cowdung+SOC, and SOC were ineffective. Results were very promising from the point of environmentally friendly control of guava fruit anthracnose.
