Dogfennel and Marestail Control With POST Herbicides

— Written By

Question: 

I have a grower with 6 to 8 inch dog fennel. Peanuts are about 3 inches across. He has a few mares tail and very small other stuff like MG. Will Gramoxone and basagran be the best recommendation?

Answer: 

Probably…use higher Paraquat rate for peanut. Strongarm POST is pretty good on small marestail.

More informed answer: 

Cadre and Strongarm give about 40% dogfennel control

Paraquat and Basagran about 25% dogfennel control

Pursuit, Cobra, Ultra Blazer, 2,4-DB about 5% dogfennel control

Strongarm at 1X rate POST (4-8 inch) gives about 85% marestail control
