NE OK | You got pretty good control considering the length of time and the rainfall. Looks like the slope and the lows, the rainfall moving the chemicals reduced the effectiveness.
In great conditions 5 weeks is good control for zidua in my experience. You aren't describing what I would consider to be very good conditions for residuals. We're experiencing similar problems and we sprayed ~may 10 and forward. Dual+sulfentrazone. Where there was too much water we've got very little control. Need to post and it's way too wet. | |

Zidua...poor grass control?
