The chapter on "Integrated Disease Management (IDM) in Solanaceous Crops" emphasizes the importance of crops like tomatoes, potatoes, peppers, and eggplants, which play a crucial role in global agriculture and human nutrition but are highly susceptible to various pathogens. To combat diseases caused by bacteria, fungi, viruses, and nematodes, the chapter advocates for IDM, a sustainable approach that integrates cultural, biological, chemical, and genetic methods to enhance crop production while reducing chemical dependency. Key IDM strategies for potatoes include crop rotation, soil solarization, resistant varieties, and use of biological control agents like Trichoderma and Bacillus subtilis. Capsicum management focuses on irrigation control, soil treatments, and biocontrol agents, while viral disease prevention relies on virus-free seeds and vector control. Additionally, the chapter outlines methods for managing bacterial wilt, Fusarium wilt, and Phomopsis blight in eggplants and tomatoes using a combination of cultural practices, biological agents, and selective chemical treatments. Overall, IDM is presented as an effective, eco-friendly solution to safeguard crop production, enhance sustainability, and address the challenges posed by evolving pathogens and climate change.
