Successfully Farming (Des Moines, Iowa, Dec. 19) – Volatility results when a herbicide like dicambra converts to a gas. When this happens, the herbicide in a gaseous form can leave the application site on a farmer's field and damage plants in neighboring fields. Even with the new formulations released by Monsanto, BASF and DuPont marketed as low in volatility, the potential for volatility still exists, says Aaron Hager, a weed specialist at Illinois.
