Abstract

Among several fungicides tested, Phytoactin L-340 and Dowicide 1 (o-phenylphenol) showed the most promise for systemic chemical control of blister rust on sugar pine in northern California. The trials included 22 tests on 224 sugar pines: five with Acti-dione BR (cycloheximide), one each with five common chemical fungicides,and 12 with phytoactin. Apparent effectiveness of the antibiotics rose to marked maximums 2 to 3 years after application, then declined.
