Open-access Incidence of Cercospora sojina Hara on soybean cultivars

AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    The reaction of 6 soybean cultivas to frogeye (Cercospora sojina Hara) was evaluated under field conditions, using a scale of notes varying from 1 to 5, being 1 for minimum infection and 5 for maximum infection. Cultivars IAC-9 and IAC-10 were susceptible; IAC-8 and IAC-12 were intermediate; and Cristalina and IAC-11 were resistant. Even the resistant cultivars had a few plants infected. Taking this into account and considering the potencial risk of this disease, roguing is recommended mainly in seed production fields.
