Early blight of potato produces

Early blight of potato produces Conidia.
Conidium is a type of asexual reproductive spore of fungi usually produced at the tip or side of hyphae or on special spore-producing structures called conidiophores.
Early blight of potatoes is caused by the fungal pathogen Alternaria solani. The disease affects leaves, stems, and tubers and can reduce yield, tuber size, storability of tubers, quality of fresh-market and processing tubers, and marketability of the crop.
