Abstract:
India is one of the world's top producers and exporters of ginger (Zingiber officinale Roscoe), making it a significant spice crop. The crop is badly affected by a number of diseases during cultivation, the most significant of which are soft rot, Phyllosticta leaf spot, bacterial wilt, storage rot, mosaic, yellows, and chlorotic fleck. Ginger rhizome rot is a seed (rhizome) and soil-borne disease, with soil having a significant impact on the occurrence and severity of the disease. The physical and chemical characteristics of the soil are a major factor in the severity of the ginger rhizome rot disease. These illnesses significantly lower the prospective profits. Integrated pest management (IPM) strategies that use appropriate microbial agents like Streptomyces spp., Bacillus subtilis, Pseudomonas spp., and Trichoderma harzianum to control soft rot are becoming more and more popular. These strategies aim to sustainably increase ginger production while also improving its medicinal and pharmaceutical properties. This study examines the geographic distribution, symptoms, losses, host resistance, disease cycle, causal organism, epidemiology, biological, chemical, and integrated control and management of the aforementioned diseases.
