What to do if a Carrot has Alternaria leaf blight:
Crop rotation: Avoid planting carrots or other susceptible crops in the same location for consecutive years.
Sanitation: Remove and destroy infected plant debris to reduce the source of inoculum.
Good irrigation practices: Avoid overhead irrigation, as wet foliage promotes disease development. Instead, use
drip or furrow irrigation to minimize leaf wetness.
Proper spacing: Provide adequate spacing between carrot plants to improve air circulation, as it helps reduce
humidity and fungal growth.
Fungicides: In severe cases, fungicides labeled for Alternaria leaf blight control can be used. Consult with local
agricultural extension services or experts for suitable fungicide recommendations and application instructions.
