  • Publication number: 20110152096
    Abstract: 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.

  • Patent number: 7884262
    Abstract: The invention provides a modified variant of dicamba monooxygenase (DMO). The invention relates to the unexpected finding that cells expressing this DMO exhibit high levels of tolerance to the herbicide dicamba. Compositions comprising DMO-encoding nucleic acids and methods of use are provided.

  • Patent number: 7851670
    Abstract: The invention provides methods for the selection of transgenic cells. The invention relates to the unexpected finding that cells expressing a gene conferring tolerance to auxin-like herbicides such as dicamba may be directly selected from non-transgenic cells using auxin-like herbicides as a selective agent. In this manner, plants exhibiting tolerance to auxin-like herbicides can be directly produced without the need for separate selectable markers.

  • Patent number: 5985793
    Abstract: A novel method is provided wherein plants are first treated with an exogenous chemical (e.g., glyphosate herbicide) and then sequentially treated with a liquid accession agent which provides improved biological (e.g., herbicidal) effectiveness such that plants are controlled with lower rates of the applied exogenous chemical (e.g., glyphosate herbicide). Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that can be exhibited when the accession agent is added to a herbicide in a tank mix or simple coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain organosilicone-based and fluorocarbon-based surfactants.

Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that may be exhibited when the accession agent is added to the herbicide in a tank mix or coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain silicone-based and fluorocarbon-based surfactants.
