Vienna, IL | 2/3 to 1 oz primero 75df with choice of residual, 3oz meso. At 3 ish inch high corn. J grass should be taking off by then. Make sure it is the actual first flush coming.
Than 1 oz impact with 1 qt atrazine at 1 ft corn. It needs to be a tall 1 ft. If the johnson grass is really bad you will need these 2 apps. If you just have some spotty j grass you can get by with 1 app just wait a little later on the first.
The plan is for the primero to take out the rhizome and first sprouts of seedling. The impact will get the second flush of seedling and stall out remaining rhizomes. | |

Johnson grass and shattercane in corn next year.
