Colletotrichum orbiculare is a potential mycoherbicide for the weed, Xanthium spinosum. The possibility of increasing the efficacy of C. orbiculare as a mycoherbicide by the addition of either a Phomopsis sp. or Alternaria zinniae under optimal and sub-optimal conditions of dew was assessed in controlled environment experiments. The addition of Phomopsis sp. had no influence on disease caused by C. orbiculare. A. zinniae did not influence the effect of C. orbiculare in the presence of 24 h dew. In the absence of dew, at a concentration of 100,000 spores per mL, A. zinniae significantly reduced anthracnose disease development due to C. orbiculae. The addition of either Phomopsis sp. or A. zinniae to C. orbiculare would not increase its efficacy as a mycoherbicide on Z. spinosum.
