Abstract
Arecanut palm is one of the most profitable plantation crops grown in India. Arecanut palm is affected by a number of diseases at different stages of growth and development. Among the fungal diseases leaf spot disease was epidemic for three years. The causal organisms were reported as Colletotrichum gloeosporioides, Pestalotia palmarum and Phyllosticta arecae these three fungal species are responsible for epidemic of disease in Karnataka and Kerala state. The main cause of epidemics is change in natural calamities like rainfall pattern, relative humidity, temperature and prolonged leaf wetness over a period of time however virulent pathogen and susceptible host these are the three elements cause disease outbreak. Hence Integrated Disease Management (IDM) strategies are crucial for effective management of leaf spot disease. Hence in this article we tried to collect much information regarding epidemic, symptomatology and management with new molecules of fungicides which are broad spectrum in nature.
