Abstract: The present investigation was carried out to identify and estimate the disease incidence of citrus (Citrus spp.) in Citrus buffer zone. The survey was carried out on major diseases like Gummosis, Sooty mold, Twinge blight, Barak eating caterpillar and Zinc deficiency. By following the methodology of per cent Disease Index, the severity of these diseases that cause considerable yield loss and its incidence were recorded from July 2020 to June 2021. Of all the agricultural diseases that threaten citrus crops, Gummosis and Sooty mold are the most devastating. Severe infections of Gummosis can cause defoliation, blemished fruit, premature fruit drop, twig dieback and general tree decline. Sooty mold induces stunting, stem pitting and low bearing of some varieties. Based on the study, Gummosis and Sooty mold has more incidence of about 61.3 per cent and 55.35 per cent, respectively. On comparing the survey period (i.e. from July to June) the disease incidence in the month of January is quite high, and it is due to the climatic factors which favors the easier and faster spread of the pathogens.
