摘要：
Disclosed is a method of controlling undesirable vegetation in a field containing a transgenic aryloxyalkanoate auxin herbicide tolerant cotton crop while limiting epinastic herbicide injury to the crop, the method comprising applying to a location in the field where control is desired a single-application herbicidal treatment consisting of an herbicidally effective amount of 4-(2,4-dichlorophenoxy)butyric acid (2,4-DB) wherein the transgenic herbicide-tolerant cotton plants of the crop comprise an herbicide tolerance gene coding for an aryloxyalkanoate dioxygenase (AAD) selected from the group consisting of AAD-1 and AAD-12, wherein the transgenic herbicide-tolerant cotton plants at the location are contacted with the herbicidally effective amount of 2,4-DB, and wherein the percentage of the foliage of the transgenic herbicide tolerant cotton plants that is epinastic after the application of 2,4-DB is reduced relative to an application of an acid equivalent amount of 2,4-dichlorophenoxyacetic acid (2,4-D). Examples of the undesirable vegetation comprises a weed species selected from the group consisting of Desmodium tortuosum (DEDTO), Mollugo verticallata (MOLVE), Acalypha ostryifolia (ACCOS), Acanthospermum hispidum (ACNHI), Cassia obtusifolia (CASOB), Ipomoea sp. (IPOSS), Ipomoea hederacea (IPOHG), Richardia scabra (RCHSC), and Sesbania exaltata (SEBEX).
