Abstract: The effect of rejuvenation times on mango cv. Amrapali under sub-Himalayan Terai region of West Bengal; the plants were headed back at 150 cm above from the ground level with six different pruning times at the instructional farm, Department of Pomology and Post-Harvest Technology, Faculty of Horticulture, UBKV. The different times of rejuvenation were considered as the treatments to find out the severity of anthracnose (Colletotrichum gloeosporioides) disease of mango under natural field condition without any control measures during 2019-20 and 2020-21. The maximum severity of anthracnose (37.03%) was recorded with the plants of Amarapli pruned during 15^th January, where as it was minimum (28.61%) with the plants pruned during 1^st December. The mean percent disease index (PDI %) for severity (January to November) of anthracnose was recorded highest with the plants pruned during 15^th January and lowest with the plants pruned during 1^st December.
