Spring Weed Control in Food Plots


Recommended Posts

I'm looking for some expert opinions ....

My food plots are in northern Minnesota, pretty close to the north end of Winnie. Grasses, weeds, and clover are just starting to grow or green up. If I want to wait for all the weeds to be growing so I can hit them with Roundup I'll have to wait at least 2 more weeks.

All my plots are due for an application of lime this year, and I will be discing in the lime.

So what's the best way to control the weeds this spring? Wait 2 weeks and hit them with Roundup, then wait another week or two to lime, disc and plant? I'm not too sold on the idea of discing after spraying Roundup because of bringing up new weed seeds to germinate, but maybe that's the best way to go.

Or should I disc and lime now, and lightly disc again right before planting to take out any new weeds, and forget about spraying this spring? When I've done this previously it doesn't seem as effective at controlling the weeds.

So .... what's your thoughts on the best way to go this spring?

go full rate of Round Up or Equivelent Class Act and Full Rate of 2 4d. Spray and 5-7 days disc and lime same trip depending on if you want to spray...wait...disc back up then come back and then lime and disc again then plant. Best bet is wait 5 days after spraying before doing anything. By adding Round Up or equivelent + Class Act or equivelent + 2 4D you will get a nice burn down. it will take a few days to work so give it time before disking. After disking it wouldn't hurt to wait a few days since it will take most of a day for that depending on size and location but give it time and then lime after a week or so and then disc again to catch any weeds you missed prior. Chemical I would recomend not going to a chain store but go to a Coop or equivelent. It isn't to hard to find them...were the places that are running like chickens with our heads cut off.

hopefully answered your question.

Thanks Code-Man. Sounds like I shouldn't till the plot until after I spray and give the herbicide a chance to work.

I go to a coop or a farm supply store to get my herbicide and fertilizer. I call it Roundup but what I use is a generic called Cornerstone (I think), it is 41% glyphosate and does the job and for a lot less money.

Round Up is just the trade name. Glyphosphate is what you want.

Round Up




if any of the generics have PLUS after it it means that they have some surfactant in it but it's nice to go with more surfactant to keep up with weeds. plus at 8 bucks a gallon for Class Act and any where from 15-25 bucks for Round Up it's hard to cut the cheapest thing instead of raising the round up rate.

Clover is something you can spray after you plant. However, you can only spray for grasses. I use Post Plus. Just sprayed today as a matter of fact. I hauled manure on my clover last winter and inherited a fresh crop of grasses. If you're really ambitious, you can spot spray with 2-4-D for thistles and other undesired broadleaf species. After I hit the grass with Poast (check spelling) Mowing every 3 weeks, 5 if it's dry, will keep other weeds down. By september, it's picture worthy.

I spray my clover with Poast and with 2,4D-B. The 2,4D-B takes care of most of the broadleafs, including thistles, and can be tank mixed with Poast.

Can't use 2,4D-B on chicory or brassicas though.

      As crazy as that might sound, May 18th isn’t a bad guess.  We were on the lake yesterday and had somewhere around 30” of solid ice with some snow on top.  This is hard January-type ice.  No honeycombing, no chipping or slush.  In fact, my Dewalt hammer drill couldn’t take it.  It’s dead.   Another foot of snow on the way this week?  That won’t help.

      Try the area where Minnehaha Falls runs into the river up to the ford dam. I've just used jig and fathead. Been several years since I've fished down there, but saw a lot of people shore fishing there. Pretty snaggy down there.

      Never tried it down there, sounds like fun. Let us know how you did.  👍

      Entries sure rolled in when I offered the case of beer.  We could meet at my Stuntz Bay boathouse if that would work.  Close to the landing, could anchor in front of the boathouse, or could park your vehicle at by the boathouse.  Maybe we could require the winner to be present, LOL.

      Thinking about trying pool 2 (from shore) for the first time tomorrow morning, ideally looking for walleye. Anyone know any decent spots or what kind of baits I should use?   Thanks in advance

      I know the owner.  In fact we rode snowmobiles together a couple days after the fire.  He lost most of his belongings.  Sounds like it was electrical.

      I drove by the spot I thought it was on the snowmobile and couldn't find it.
