ANGULAR LEAF SPOT OF CUCUMBER IN ENGLAND.

- Abstract
This article presents a study on angular lead spot of cucumbers in England. In September 1957, frame-grown cucumbers from Swavesey, Cambridgeshire, submitted for diagnosis, showed symptoms closely resembling those of angular leaf spot. Ten isolates of a Pseudomonas species, all of identical colony morphology, were readily obtained in pure culture from lesions on the fruit, leaves and stems. A detailed study was made of the morphological, cultural, biochemical and physiological characters of two reisolates, and also American and Danish strains of Pseudomonas lacrymans. Minor differences were found between the strains. Antisera prepared in rabbits against one Danish and one English isolate cross-agglutinated to titre, and no antigenic differences between the two isolates could be detected by mirror adsorption tests.
