Tomato Early Blight and its Management in sub-Saharan Africa.
Abiala M, Stam R
Crop Improvement
Tomatoes grown in backyard gardens and small farms across Africa are under threat from a fungal disease that spreads fast, resists common sprays, and has almost no regional early-warning system to catch it before it wipes out a harvest.
Early blight is a fungal disease that attacks tomato plants, causing dark spots on leaves and ruining fruit. In sub-Saharan Africa, farmers are struggling with it but scientists haven't studied it well enough to know exactly which fungal strains are spreading or how to stop them effectively. The sprays farmers use are increasingly failing, and there's no organized plan to track or manage the disease across the region.
Key Findings
Early blight caused by Alternaria fungi is widespread in sub-Saharan Africa but remains severely underreported due to limited field surveys and molecular studies.
Alternaria populations in the region show rising resistance to synthetic fungicides, the primary management tool currently in use.
Integrated disease management strategies are either absent or inconsistently applied across sub-Saharan African tomato-growing areas.
chevron_right Technical Summary
A fungal disease called early blight is quietly damaging tomato crops across sub-Saharan Africa, but it's barely being tracked or studied. Farmers are over-relying on fungicides that are losing effectiveness, and no coordinated strategy exists to stop the spread.
Abstract Preview
Early blight (EB) and related diseases are caused by various Alternaria species and pose a serious threat to global tomato production. In sub-Saharan Africa (SSA), EB remains largely underreported ...

The tomato is a plant whose fruit is an edible berry that is eaten as a vegetable. The tomato is a member of the nightshade family that includes tobacco, potato, and chili peppers. It originated from western South America, and may have been domesticated there, in Mexico, or in Central America. Th...
