| FWIW, back in the day when Callisto was new and expensive, and killing weeds in beans was easy, we two-tripped corn and the second pass was this:
3/4 oz. Steadfast, 1.6 oz. Callisto (we did 80 acre loads and that was one gallon without measuring), 1/4-1/3# atrazine. That amount of atrazine was synergistic to both the ATZ and Callisto for sure. If the stand of corn was good, you could sit in the combine for a hundred hours and never see a weed. |
How much atrazine to “synergize” chemicals?
