New to deer hunting / farming/ food plots so this may be a very basic question but I can't seem to find it on Butyrac label. Area 9a, South Mississippi, planted 1 acre Durana in April in effort to do perennial clover plot. Clover came up nice but so did weeds. Got behind on weeds by June(like 2 feet tall weeds, now I know how fast weeds grow) but have since mowed 3 times this summer to approximately 6 inches. At 6 inches I was just nipping the tops off a little of the clover but passing over most of it. Sprayed clethodim for grasses Aug 3 and that seems to have worked now I want to hit broadleafs but Butyrac 200 label says do not spray when above 90 degrees. Clover is now covering approx. %70 of field, but buried by (if my rookie weed identification is correct) smartweed, puncturetine/sandspur, broom sage, and miscellaneous weeds. Normal planting dates here are Sep 1st to 20th but the temps wont go consistently below 90 till mid/late September. I have extra Durana seed and want to overseed the bare areas . Question 1: How long after spraying Butyrac do I need to wait before overseeding with more clover?? It seems that next year I would spray for weeds in Spring so not have to worry about high temperatures and get ahead of weeds but this year I am a little stuck: I have a nice clover patch but it is buried by weeds. Question 2: Since clover seems to be looking good even though it is late August, can I spray this weekend even though temps will be near 90? Or should I just mow now and spray Oct. 1? Pictures are from before first mowing, june 23, tall weeds are much shorter now but the low growing ones seem to be thicker and choking out the clover. My mowing is not affecting low growing weeds . Thanks in advance for any and all advice!
