NE Iowa | Corvus is a blend of Balance Flexx and a grass herbicide that doesn't have a brand name that I know. Balance Flexx has the active ingredient isoxaflutole which is a group 27 herbicide and is a HPPD inhibitor. The grass component has the active ingredient thiencarbazone which is a group 2 herbicide and is an ALS inhibitor. I used to use Corvus but after reading some horror stories on here I have switched to using Balance Flexx in a mix with generic Dual and Atrazine. | |
