Disclosed are compositions and processes for controlling velvetleaf. These compositions comprise synergistic compositions of a Colletotrichum coccodes and chemical herbicides. Use of the synergistic compositions of the subject invention enhances the value of the Colletotrichum coccodes by reducing the amount of herbicide needed and by extending the range of environmental conditions in which the Colletotrichum coccodes will function.

Synergistic herbicidal compositions comprising Colletotrichum coccodes

There is disclosed a process for controlling undesirable vegetation, espelly velvetleaf by applying Colletotrichum coccodes spores onto the undesirable vegetation or onto the situs of the undesirable vegetation. The composition including the fungus spores in an agricultural carrier as well as the growing of the fungus on solid or liquid media are also disclosed. The spores germinate, infect the undesirable vegetation and result in a pathogenic disease which kills or reduces the growth of this undesirable plant.

Process for controlling undesirable vegetation with Colletotrichum

Disclosed are compositions and processes for controlling undesirable weeds. These compositions comprise synergistic combinations of microbial herbicides and or plant growth regulators. Use of the synergistic compositions of the subject invention enhances the value of the microbial herbicide by reducing the amount of microbial herbicide needed and by extending the range of environmental conditions in which the microbial herbicide will function.
