Strategies for Coffee Leaf Rust Management in Organic Crop Systems

Coffee is a crop of great economic importance in many countries. The organic coffee crop stands out from other production systems by aiming to eliminate the use of synthetic fertilizers and pesticides. One of the most important limitations in the organic system is the management of diseases, especially coffee rust, which is considered the main disease of this crop. Coffee rust causes a production slump of up to 50%, significantly affecting the profitability of coffee growers. This work aims to review the integrated rust management in organic coffee crop in different producing countries. Regarding the disease management strategies, this review addresses the use of rust-resistant cultivars, cultural management, biological control, use of plant extracts, and chemical rust control by cupric fungicides. Considering the importance of the organic system, the increase in world coffee consumption, and the potential market for this kind of coffee, this review may help researchers and producers looking for alternative strategies to control rust in an organic coffee cultivation system.

Automated summary

Organic coffee is an economically important crop globally, but faces challenges in disease management, particularly coffee rust. Effective disease management strategies include using rust-resistant cultivars, cultural management, biological control, use of plant extracts, and chemical rust control. This review aims to provide insight for researchers and producers seeking alternative strategies to control rust in organic coffee cultivation systems.
