Mitigating against Sclerotinia Diseases in Legume Crops: A Comprehensive Review

Abstract

Legumes are essential foods for man and animal. They contribute to food security globally. However, they are negatively affected by Sclerotinia diseases caused by Sclerotinia sclerotiorum, which infects over 600 plant species. There is a limited number of review studies on the management of the Sclerotinia sclerotiorum disease in legume crops. Here, we explore earlier studies on the occurrences, yield losses, and other negative effects caused by Sclerotinia spp. in legumes. Additionally, we studied the various strategies used in controlling Sclerotinia sclerotiorum diseases in legume crops. We conclude that the impact of Sclerotinia diseases on legume crops causes an economic loss, as it reduces their quality and yield. Among the management strategies explored, genetic control is challenging due to the limited resistance among germplasm, while biological agents show promising results. Fungicide application is effective during outbreaks of Sclerotinia diseases. Lastly, this review has uncovered gaps in the current knowledge regarding the alleviation of Sclerotinia diseases in legume crops.
