Abstract:
Increased greenhouse gases are a severe issue world over. Climate change is likely to influence the epidemiology of diseases and pests. A change in climate in the recent past has influenced disease and pest cycle and their epiphytotic in many crops. Flue-Cured Virginia (FCV) tobacco grown in Andhra Pradesh (A.P) and Karnataka, India, in an area of about 2.2 lakh ha produces around 230 M.Kg annually. The crop is a major commercial crop with a lot of export potentiality and farm economy. FCV tobacco is grown in Karnataka as rainfed, while it is an irrigated crop in Andhra Pradesh (AP), which suffers due to many pests and diseases in nursery and field crops resulting in economic loss. Though, suitable crop protection strategies have been in practice hitherto, minor diseases and pests have evolved as a major concern due to changes in climate over a period. Crop protection strategies are needed to cope-up with the changed climatic conditions like temperature rise and periodical droughts.
