Differential Susceptibility of Rice Leaves and Panicles to Piricularia Oryzae

Abstract

Greenhouse tests of differential susceptibility of rice (var. Zenith) seedlings and panicles to Piricularia oryzae indicated that seedlings inoculated with race 11 (IA-2) were highly resistant, but the panicles were susceptible. When only panicle necks were exposed for inoculation, the percentage of necks blasted was high at boot stage but gradually decreased during exsertion of panicle necks. Panicle ears were susceptible to blast from the time of exsertion to maturation of grain.
