Abstract

Two anthracnose diseases caused by Colletotrichum gloeosporioides have been found in Stylosanthes spp. in northern Australia. The two diseases can be readily distinguished by their symptoms and their pure-culture characteristics. The disease classified as type A was widespread, but the other, type B, was found at only two localities. In spray-inoculation tests under controlled conditions, S. guianensis cv. Endeavour was highly susceptible to type B isolates, and some lines of S. fruticosa, S. humilis, S. scabra and S. viscosa were highly susceptible to the type A isolates. Two pathogenic races of type A were recognized from the reaction of S. viscosa 33941 towards them.
The importance of these diseases is discussed, together with aspects of disease dissemination and future control strategies.
