Abstract:

The importance of the citrus crops is recognized throughout the world. Despite tremendous advancements in agricultural technology, citrus fruit production is still considered a significant challenge. Various biotic factors have trampled down the production rate of Citrus in many places. Among them, canker caused by Xanthomonas axonopodis pv. citri (Xac) and Xanthomonas citri pv. citri (Xcc) is of great importance. Infection caused by Xac leads to lesion development in leaves, fruits, and stem. Defoliation and early fruit drop can occur as a result of severe infection, resulting in a loss of fruit output. Preliminary management techniques involve quarantining and sanitizing. Chemical copper-based bactericides are frequently employed in places with large-scale production. However, the continued use of chemicals, on the other hand, has led to the evolution of resistant microorganisms and increased the rate of soil pollution. Various alternative strategies have been suggested to address this issue. This review will go over the advances in biocontrol agents that have been used to combat the disease.
