US Patent:

57470294, May 5, 1998

Filed:

Aug 7, 1995

Appl. No.:

8/512093

Inventors:

Harrell L. Walker - Ruston LA
Anthony M. Tilley - Minden LA

International Classification:

A01N 6300

US Classification:

424 935

Abstract:

A method for the biological control of various weeds such as sicklepod using the fungus Myrothecium verrucaria. In a typical application, conidia of the fungus are applied with liquid surfactant to the weeds in amounts effective to produce typical plant lesions which kill or suppress, and thus control, the weeds. In another embodiment, phytotoxin produced by the fungus is used to control the weeds. In still another embodiment a synergistic combination of M. verrucaria and the fungus Alternaria cassiae is used to control sicklepod and in a fourth embodiment phytotoxin produced by M. verrucaria is used synergistically with A. cassiae to control sicklepod. A strain of M. verrucaria is 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 has been assigned the number IMI 368023.

Appl. No.:

8/234264

Inventors:

Harrell L. Walker - Ruston LA
Anthony M. Tilley - Minden LA

International Classification:

A01N 6304

US Classification:

504117

Abstract:

A method for biological control of pest grasses such as crabgrass using two species of a fungus selected from the genus Curvularia. The fungus is applied to the grass in amounts effective to produce typical plant lesions which kill or suppress, and thus control, the grass. The fungus may be administered with a surfactant or as granules, either of which may include additives such as glucose to enhance the pathogenic action of the fungus. Two species of the fungus are on deposit with the Department of Biological Sciences, Louisiana Tech University in Ruston, La. and with the International Mycological Institute in Surrey, UK and have been assigned the numbers MT-5 and CG-L.

International Classification:

A01N 6304

US Classification:

504117

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).
