Formerly NE North Dakota, now NW MN | I've had good luck with cadet and harmony, though I'm not sure i've hit ones quite that tall. The leaves tend to get really waxy when their that big, so I would try to avoid spraying if the Delta T is not favorable. I like to use a good shot of AMS to help uptake and try to spray when it's like 70-75ish to give a long window for plant uptake. |
