EngeniaTM Herbicide: An Advanced Dicamba Formulation for Dicamba Tolerant Crops.

Dicamba has been a highly effective weed management tool for nearly 50 years.  It is the sixth most widely used herbicide in the United States with more than 25 million acres of farmland treated annually.  Dicamba effectively controls or suppresses over 190 broadleaf weeds including many problematic weed species such as ragweed (Ambrosia spp.), common cocklebur (Xanthium strumarium), common lambsquarters (Chenopodium album), morningglory (Ipomoea  spp.), pigweed (Amaranthus spp.), and horseweed (Conyza canadensis).   Research on an experimental dicamba formulation, Engenia herbicide    indicates that it reduces potential volatility more than improvement seen with Clarity^® herbicide over Banvel^® herbicide.   Engenia herbicide is optimized to further reduce volatility potential of dicamba through innovation based on the BAPMA (N, N-Bis-(aminopropyl) methylamine) form of dicamba.  Engenia herbicide in combination with dicamba tolerant crops will be an important tool for herbicide resistant weed management.  Dicamba tolerant soybean and cotton will enable preplant burndown without planting interval and over the top application of Engenia herbicide   Engenia herbicide s auxin agonist mechanism of action provides soybean and cotton growers the opportunity to effectively control herbicide resistant and difficult to control weeds.    Stewardship is necessary to ensure the sustainability and durability of the dicamba tolerant crop system.  Integrated weed management strategies that combine herbicide, cultural and mechanical control techniques such as alternative herbicide mechanisms of action, crop rotation, and sanitation need to be utilized to effectively manage herbicide resistant weeds and protect the utility of dicamba-tolerant cropping systems. We anticipate that Engenia herbicide will be registered in 2013.
