- Abstract
Rice is attacked by a number of insect pests and among them, leaf folder, Cnaphalocrocis medinalis (Guenee) (Lepidoptera: Crambidae) is also one of the major pests. The experiment on the seasonal incidence and management of rice leaf folder, C. medinalis through Bio-intensive pest management (BIPM) was conducted during the kharif, 2018-19, at the Instructional Research Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. Results indicated that the incidence of leaf folder, C. medinalis was first observed as leaf folds during 35th standard meteorological week (SMW) i.e. the first week of September with 0.78% leaf folds which gradually increased to 7.39% leaf folds during 43rd SMW i.e. last week of October. From the management point of view after treatment (pooled average of 13 observations), the data showed that BIPM practice (T1) was significantly superior with the lowest number of leaf folds (1.41%) as compared to 2.77 and 3.55% in Farmer’s practice (T2) and Control (T3), respectively.
