Fungicides and alternative products in the mycelial growth and germination control of Alternaria tomatophila
This study aimed to characterize the in vitro effect of different products on the mycelial growth and conidial germination of Alternaria tomatophila, the etiologic agent of tomato early blight. The experiment was installed using a completely randomized design, in factorial scheme 5x4, with five leve...
