dc.description.abstractThree anthracnose diseases, caused by three different Colletotrichum spp., of importance in South Africa were studied. Anthracnose of Lupinus a/bus was recorded for the first time and the causal organism described as C. tortuosum Koch & Baxter. Chamaecyticus palmensis was added to the host range of C. trifolii. Differential Phaseolus vulgaris cultivars were used to distinguish seven races of C. lindemuthianum. None of 30 local bean cultivars showed resistance to the races of the fungus present in South Africa. Different methods for the detection of C. lindemuthianum on bean seed were evaluated. The paper doll method was found the most effective. Various fungicides were evaluated for their effectiveness to control seedbome C. lindemuthianum. Benomyl was found to be the most effective.
