Benomyl and benodanil were tested for control of Cronartium quercuum f. sp. banksianae on five species of pine in a nursery bed. Both fungicides were applied as a soil drench either before or after inoculation with C. quercuum f. sp. banksianae. Symptoms were most frequent on control seedlings and those treated with benomyl but rare on seedlings treated with benodanil.
