Methods for weed control using plants having dicamba-degrading enzymatic activity

摘要

The invention provides methods for weed control with dicamba and related herbicides. It was found that pre-emergent applications of dicamba at or near planting could be made without significant crop damage or yield loss. The techniques can be combined with the herbicide glyphosate to improve the degree of weed control and permit control of herbicide tolerant weeds.

主权项

1. A method for controlling weed growth in a crop-growing environment comprising:
a) applying a herbicidally effective amount of an auxin-likedicamba herbicide to a crop-growing environment; b) planting a transgenic seed of a dicotyledonous plant comprising a nucleic acid encoding a polypeptide having dicamba-degrading enzymatic activity in soil of the crop-growing environment within 21 days of applying the herbicide; and c) allowing the seed to germinate into a plant.
