Present Studies were carried out on seasonal incidence, varietal screening and botanical control of rice leaf folders, Cnaphalocrocis medinalis Guenee and Pelopidas mathias Fabricious in South Gujarat. In the study of seasonal incidence larval population (0.50 larva/plant) and per cent damaged leaves (0.55) of rice leaf roller, C. medinalis initiated from 36th standard week and reached it's peak level (3.12 larvae/plant and 3.20 per cent damaged leaves) during 43rd standard week in kharif-2005 while the larval population (0.53 larva/plant) and per cent damaged leaves (0.72) of rice leaf roller initiated from 13th standard week and reached to it's peak level (1.51 larvae/plant and 1.75 per cent damaged leaves) during 15th standard week in summer-2006.Out of twenty one varieties screened, minimum per cent damaged leaves by rice leaf roller was recorded in variety GR-103 (0.27) with scale-1.The treatment chlorpyriphos 0.05 per cent found significantly superior and most effective treatment than rest of treatments with lowest per cent damaged leaves (0.52 for rice leaf roller).
