During 1961-67 loss of yield from panicle infection by Pyricularia oryzae depended on the time of infection, the earlier the infection the greater the loss. There was no loss but slight damage in quality when infection occurred 3 weeks after heading. Neck blast showed the closest correlation to yield and quality loss, and disease intensity was best estimated 30 days after heading.
