lawfarms - 7/1/2015 06:24 Only way to know for sure is get a sample pack of seeds and try it. Then if we get a rain and it reactivstes the chem you could kill of what you planted..... I was lucky as I just sprayed lv6 and rup pre with the plan to spray Zidua chasing the planter and the. Post 2x with Liberty. I've got some ALS resistant burrs and rup resistant twh that I was gonna try and kill. Turns out both the burs and twh that are up really don't like lv6. I'm spraying now to cleanup the fields and it's frying em. I'll spray with rup right at cover planting time to get anything that may have just came up and hopefully rup will still kill 2" tall twh if any more emerges between now and then. I found a source for some Sudan grass as it's less then $10/acre. The old $30/acre cover budget isn't gonna happen as I wanna add the $20 savings on cover seed to the tile, dirt work, or fertilizer budget. If you were wanting to graze cattle on it after nov 1 you might look at a priceyer mix.
