Síntomas y signos
Se observan pústulas zoosporangiales en el envés de las hojas, agallas del tallo en forma de huso, hipertrofias florales, hipertrofia de inflorescencias enteras o partes terminales de inflorescencias e infecciones de vainas. Las pústulas zoosporangiales pueden cubrir los órganos florales hipertrofiados.
El pseudohongo crece con micelio intercelular hialino, formando haustorios globosos. Los zoosporangios se disponen en cadenas, son globosos a ovales, hialinos. Las oosporas pueden permanecer infestando en semilla y suelo.
En general los daños y pérdidas económicas no son graves, pero dependerá del nivel de inóculo inicial y las condiciones ambientales durante el crecimiento del cultivo.
