Abstract
Reliable production of infective spores is an essential requirement in the screening of putative biological control agents. We report the development of a novel and simple medium for the production of viable oospores of Aphanomyces cochlioides, one of the principal causes of damping off of sugar beet. The semi-solid medium consists of 5 g l-1 corn meal agar and 1 g l-1 mycological peptone and supports the development of 2.25 x 103 oospores cm-2 in 5 d. In a plant bioassay for post emergence damping off, the oospores had a consistent pathogenic effect with 50± 5.7% damping off induced by 170 oospores g-1 soil (-15 kPa matric potential) after 20 d. Higher numbers (1700 g-1 soil) produced 88.8±9.1% disease in emerged plants after 20 d.
