Fungicide Trials for Control of Phomopsis Canker of Douglas-fir at a Northern California Nursery

Based on in vitro evaluation of sixteen fungicides, five were field-tested for efficacy against phomopsis canker of 2 + 0 Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). All gave significantly better control than no treatment. Benomyl, the fungicide registered for phomopsis control, was more efficacious than mancozeb and imazalil but was not as effective as diniconazole or chlorothalonil.
