Access guides, bulletins, tools, and training materials for soybean production.
Have you noticed bronze to purple leaves, premature leaf drop, or poor-quality seed in your soybean field? Your crop could be suffering from Cercospora Leaf Blight (CLB). What causes it? Cercospora Leaf Blight is caused by the fungus Cercospora kikuchii. The disease survives on infected crop residue and seed, spreading through wind and rain, especially during warm, humid weather. Lead to yield losses of 10–30% under moderate disease pressure, with losses exceeding 50% in severe epidemics when susceptible varieties and favourable weather coincide. Protect your crop by: • Planting certified, disease-free seed • Rotating crops • Managing crop residues • Growing tolerant varieties • Scouting fields regularly • Applying recommended fungicides when necessary Early detection and timely management are the best ways to protect your soybean yield.
