I'd go very light with oust. Oust still spooks me but if u r very careful and use very light use- ok. On bottom ground or ground that doesn't drain well- I would not use oust. Bald spots- u got a million options....
Super light oust, roundup and I'd just mix in atrazine as it will also keep weeds at bay and carry over to next yr which is fine. Basically- anything to get those areAs "clean" for when u spray next spring. Next spring u will want to be spraying as bare & clean ground as possible with Round up and atrazine. Just because I'm Not a huge oust fan (use it but lightly)- I personally would burn it down a few times with Roundup, 2,4-d, atrazine and I'd probably add another residual that will be long gone by spring. If well drained ground- .25-.5 oz oust. I'd probabably lean towards dual or 2-6 oz of plateau this season. I'd pry do 2 sprayings. Last one in sept or oct and that would only include roundup, atrazine & 2,4-d. All of what u spray- u want gone by April next yr or so. (All of these & rates will be) Only thing u want carry over that lasts into next year is atrazine. U are gonna add more in spring too.
