Integrated Crop Management to Control Anthracnose (<i>Colletotrichum gloeosporioides</i>) of Mango

Abstract

An experiment was conducted to develop an Integrated Crop Management (ICM) practice for controlling anthracnose (Colletotrichum gloeosporioides) of mango with emphasis on non-chemical means and achieving higher yield. The treatments were T₁ = Pruning (P) + Weeding (W) + Spading (S) + Fertilizer application + Garlic Extract (3 times) + Irrigation (14 days interval); T₂ = P+W+S + Fertilizer application +GE (2 times) + Dithane M-45 (one time) + Irrigation (14 days interval); T₃ = P+W+S + Fertilizer application + Bagging (60 days before harvest) + Irrigation (14 days interval); T₄ = P+W+S + Fertilizer application + Dithane M-45 (3 times) + Irrigation (14 days interval) and T₅ = Control (Untreated). It was found that T₄ treated plant resulted the highest (14%) fruit retention per plant followed by T₁ (13.75%). The lowest (8.50%) was obtained from T₅ (control) at 60 DAFS. Treatments T₄ and T₁ produced the highest percentage (94 and 92, respectively) of healthy fruits and the lowest (86%) was obtained from T₅ (control). The highest yield was obtained from T₄ and T₁ treatment (18.88 and 17.47 t/ha, respectively) and the lowest (4.48 t/ha) was found in T₅. The highest (26.50) soluble solid was obtained form treatment T₄ followed by T₁ (25.75) and the lowest (24.00) was recorded from T₅. The highest disease incidence and severity was found in T₅ (66.67% and 3.00%, respectively).
