"Milk was tested in kale plants naturally infested with aphids and powdery mildew. •Milk application reduced powdery mildew and aphid populations. •Dead aphids were found to be parasited by a fungus identified as Cladosporium sp. •Fungicides reduced Cladosporium sp. growth in vitro but not milk. •Milk separately or with Cladosporium sp. reduced aphid populations in vitro."
