ABSTRACT:
A method for biological control of pest grasses such as crabgrass using the fungus Cochliobolus intermedius R. R. Nelson (anamorph Curvularia intermedia Boedijn). The fungus is applied to the grass in amounts effective to produce typical disease symptoms which kill or suppress, and thus control the grass. The fungus may be administered as a foliar application or as granules, either of which may include additives such as surfactants, glucose or starch to enhance the pathogenic action of the fungus. Four isolates of the fungus are on deposit with the Department of Biological Sciences, Louisiana Tech University in Ruston, La. and with the patent collection of the International Mycological Institute in Surrey, UK and have been assigned the numbers 361688 (MT-5), 361689 (CG-L), 375263 (MT-6) and 375264 (MT-7).
