Abstract

The different lesion-type isolates of incompatible races of Pyricularia oryzae were used to compare the potential for suppressing leaf blast by pre-inoculation to rice plants. Although the leaf blast was suppressed by pre-inoculating any incompatible isolate of blast fungus, there were some differences in the degree of leaf blast suppression among the isolates used. The highest suppression of leaf blast was observed when the isolates inciting the quite small eyespots with brown margins (bg-type) were pre-inoculated to rice plants.
