Effect of prevention against rice blast disease by resistance-inducing fungicide applied to seedling box in Hyogo Prefecture

Abstract

The preventive effect on leaf blast disease of probenazol and isotianil seedling treatments was high under a slight-occurrence condition of blast disease, including a QoI-resistant strain. Fipronil-probenazol, and isotianil showed high prevention values (over 85) until 58 days after planting under moderate- and heavy-occurrence conditions of blast disease, including a QoI-resistant strain.
