Edge of RRV MN | 1/4# is all that is needed to heat up Callisto for synergy. If rotation isn’t a concern I would use 3/8-1/2# to get a little atrazine help. 6oz of Buctril per acre heats Hppd’s with very similar synergy to Atrazine. I always use Buctril when mixing with Laudis if rotating to a crop like sugarbeets the year following corn or if you are in an area with atrazine restrictions. You can get a little Buctril leaf tip burn but the weeds will be dead. | |

How much atrazine to “synergize” chemicals?
