I'm getting ready for my fall plots and after one season with the plots the weeds are quit heavy. Should I mow them down then apply Roundup or leave them tall? They are about 12"-14" high right now.

Leave 'em tall. You'll need some leaf area to soak up the chemical.

Im using it now. if you let the weeds burn then try mowing them it may be had to mow and will turn to a rope like weed. Id mow wet or alive then. roundup.
Do you plan to till up the lot? If so dont use roundup just till up the plot with all the weeds in it.

In a perfect world, I'd spray, till, spray, till, plant. But in most cases, due to lack of time or equipment thats not possible. If I were you I would spray now, then in another month till and plant. Try to plant just before a rain. That way, whatever you plant should germinate quickly and hopefully out compete the weeds.

Do you mow before you spray? I know with my home garden after the second tilling you have gotten most of the weeds so I understand what you say about the repeat tilling.

if you mow you will need to wait about 5 days to spray for best results. i would do this only because it will get the new growth under th tall stuff

FL hit it right on the head. If you mow, you need to wait a few days in order for the weeds to begin growing again. As long as they are actively growing they will absorb the herbicide and you'll get a good kill. If the weeds around only a foot tall, you should be able to get a good kill of everything just by spraying without mowing.

DO NOT mow before you spray.

Roundup works by contact with the leaves on the plant. You'd get a kill if you mow but it would work better if you spray on the weeds before you mow.

You actually probably waited a little long to spray. As plants get bigger they also get harder to kill. Roundup works best when the plants are fairly young.

When you spray try not to do it right in the heat of the day. A misconception with Roundup is that it works great in the heat because it burns the plant. However I was at a chemical seminar awhile back and they told us to spray in the cooler part of the day. The plant tends to soak up more when its not really hot.

Thanks everyone for the input. I would think late afternoon would be best then so it stays moist all night. My weeds are not too thick and I think I should be able to get contact on everything big and small.

No mowing!

Do not mow the weeds before you spray at all. Use a good surfactant with the round-up and spray in the morning or evening to prevent drifting. The main thing is to know what kind of weeds you are dealing with. The younger the weeds the better. If you can find someone to spray it with a restricted use licensce (sp) then they can purchase a stronger version of the chemical than you can. If weeds are too tall then I recommend discing the ground first then wait for the weed to germinate and get about knee high and then spray. Any weed that is over knee high is going to be hard to kill this time of year. Drought stress makes it tougher. Just a few thoughts from an old soybean and cotton farmer from the delta of Arkansas.

Also if you spray and get a good kill then I recommend no till planting. I you have to work the ground to plant it then another generation of weeds will sprout along with your seeds. Just be ready to spray as soon as the plants are big enough to withstand the chemical. Always follow the label!!!!!!

You mow it to 6" in height..think of it as dosage (like medicine) 600mg does not do the same thing for a 90lb wman as it does for a 350 linebacker, right? It also fores the plant to take in more nutrients (or roundup) due to the stress of being cut.

we always mow before we spray. we tried it with out mowing 1 time and it just didn't kill everything. So we brushhog, spray, let sit for 2 weeks, till & plant. Works great for us.

definitely mow now then wait 1-2 weeks and nuke the area the round-up will work on all the new growth encourage by the mowing. It will be hard to kill the weeds at the height they are now. MOW, WAIT, SPRAY.

Spray it before you mow. Depending on the weed you may or may not be off label. At any rate, if you're worried about not getting a good kill, just up the chemical rate a few ounces and use a surfactant.

Sounds if the majority are saying Mow, Wait & then Spray.:confused:

Cannot locate any info from the Monsanto web site so that is why I'm trying here.

Thanks and it looks as if i will follow the majority.

It really depends on how much time you have to wait before you plant. If you spray now, you wait 2 weeks for chem to work, then you can mow/plow. Depending on the type of weed, you may not even have to mow after spraying---the weeds may lay completely down (that's my experience with grasses and non-woody type weeds). On the other side, if you mow, wait 2 weeks, spray, wait another 2 weeks for chem kill---well, you're a month in before you can even touch the ground which puts you near the end of August. That's cutting it close in some places.

12-14" isn't a very tall weed. I've sprayed stuff up to shoulder high and had good kill with less material to mow. Less mow chaff is preferable for subsequent plowing/tilling for a better seedbed.

I just went to a food plot seminar for the second year in a row, one of the first things I learned is. Spray and till it in 30 min. When you wait 2 weeks, that’s two weeks of new weeds that develop. Spray it , till it, plant it as soon as you can. This allows your plants to get started and that gives you cover to stop weed growth

You should try a "how to participate properly when joining a new site" seminar. 😜

Welcome to the boards!!! I am not sure why it bothers some folks or that some of the same general members feel the need to point out when a newer member "wakes up" an old threads? They system is set up in a "strange way" in that some of the older threads appear directly under the topic on the main page. For example, directly below the text box I am typing in is a thread entitled "spray or mow 1st??" and it was started in 2006. If I were to open it and reply it moves it to the top of the boards, there is nothing wrong with that....

Again, welcome aboard, hope your membership turns out to be what you had hoped for....if you're interested we run a deer contest every fall, but registration will be closed next weekend, so get it now if you're interested....here's the 411....
