Hey Coup I am having trouble killing waterhemp with 1 oz. Impact. They get stunted but don't exactly die. The label of Impact allows up to 2 ounce now. Should I be going heavier on the Impact or any suggestions to add with it for better waterhemp control? I used Anthem Max and Balance Flex pre last year but activating rainfall was scarce and on manured ground waterhemp pressure is high.
Doubt if 2 oz will kill ether. TWH is pretty much getting immune to HPPD chems on emerged TWH..
In your situation with heavy TWH pressure would try using pre 3.2 oz Anthem Maxx, 3 oz balance Flexx, 3 oz Gen Callisto and 8 oz Gen Dicamba. Then post 2-3 leaf corn with 1 oz Impact, 2.5 oz Anthem Maxx, 1 lb Atrazine. What I have found only way to effectively control TWH is to keep it from coming up.
