- Ionic liquid forms of the herbicide dicamba with increased efficacy and reduced volatility
-
Twenty eight new dicamba (3,6-dichloro-2-methoxybenzoic acid)-based herbicidal salts, have been synthesized and characterized in order to attempt to improve the efficacy of this widely known herbicide used to protect maize, grassland, and other cultures. The new compounds, most of which are ionic liquids by definition and three of which are solids melting above 100 °C, were prepared by pairing quaternary tetraalkyl- or alkoxyammonium, piperidinium, imidazolium, pyridinium, morpholinium, quinolinium, and phosphonium cations with the dicamba anion. Growth chamber and field test data suggested that ionic liquid forms of dicamba offer substantially increased efficacy which would allow less to be applied in the field. Compared to the commercial dicamba free acid product, improved physical properties were observed including higher decomposition temperatures and reduced volatilities, suggesting a potential reduction of overall environmental impact of this herbicide.

- HERBICIDAL COMPOSITIONS AND METHODS OF USE
-
Disclosed are compositions and methods of preparing compositions of active herbicidal ingredients. Also disclosed are methods of using the compositions described herein to improve herbicide delivery and efficacy, enhance herbicidal penetration, reduce herbicide volatility and drift, diminish environmental damage from herbicides, decrease water solubility and volatility of herbicides, and introduce additional biological function to herbicides.
