Integrated Pest Management in Mustard: Extension Approaches for Sustainable and Climate-Resilient Production

Abstract/Preface

Indian mustard (Brassica juncea) is an important rabi oilseed crop in India and contributes significantly to edible-oil production and farm livelihoods. However, production is affected by several insect pests and diseases, particularly mustard aphid (Lipaphis erysimi), painted bug (Bagrada spp.), mustard sawfly (Athalia lugens proxima), Alternaria blight, white rust and Sclerotinia stem rot. Frequent and unnecessary insecticide use can increase production costs and adversely affect beneficial organisms. Integrated Pest Management (IPM) provides a practical approach based on prevention, regular crop monitoring, conservation of natural enemies, biological and botanical methods, and need-based chemical control. Climate variability further complicates pest management because temperature, rainfall and humidity influence pest development and disease occurrence. This chapter discusses the major pest and disease problems of mustard and reviews IPM practices with particular emphasis on agricultural extension. Farmer Field Schools, frontline demonstrations, KVK advisory services, participatory surveillance and digital communication are discussed as important mechanisms for improving farmers’ ability to identify problems and make timely management decisions. The chapter also proposes a climate-resilient extension approach that connects field surveillance, weather information, advisory services and farmer feedback.
