Pre-emergence control of smartweed

Anyone try using Pendulum Aquacap for pre-emergence control of smartweed in clover plots? After reading the label, it seems like it should work.
 
I'm not for it or against it yet. Just wondering how you stumbled onto this and what label you looked at (I know, duh) and what on the label intrigued you.
 
Pendulum AquaCap is a landscapers herbicide, not labeled for crop use;
Pendulum AquaCap Herbicide is labeled for use on the following areas:
  • Airports
  • Athletic fields
  • Bulbs
  • Conifer nurseries
  • Driveways
  • Fence lines
  • Golf courses
  • Grounds maintenance
  • Hardwood nurseries
  • Landscape
  • Lawns
  • Mulch beads
  • Non-bearing fruit trees
  • Non-bearing nut trees
  • Non-cropland areas
  • Ornamental production
  • Parking lots
  • Parks
  • Perennials
  • Picnic areas
  • Railroads
  • Rights-of-ways
  • Schools
  • Shelter belts
  • Shrubs
  • Sod farms
  • Stone gardens
  • Storage areas
  • Tank farms
  • Turfgrass
  • Under asphalt
  • Under concrete
  • Vacant lots
  • Windbreaks
 
It'll probably kill your clover;

What you want is Thunder or Imox, these are specifically labeled for clover. Check out some of my other threads for proper timing and methods to use Thunder herbicide on clover.

It's commonly recommended for use on stiltgrass and mile a minute in wooded areas. Clover is not listed as a controlled plant (hop clover is not really clover).
 
I've tried Imox with only mediocre success.
I almost couldn't find your response way down here! Pendulum Aquacap's active ingredient is about the same chemical structure you find in Prowl, a herbicide that's been used on soybeans for decades. If one digs deep enough, as opposed to overreacting and flooding the thread with long lists of words formatted in big type, one might find a thought or two about using the generic (forget the trade name - its all marketing - well, and EPA registration) to control some weeds in pastures with clover.

Well managed you might get away with it on established clover for pre-emergent control of smart weed, but the herbicide has to be applied timely and then it needs to get rained or irrigated into the soil. And forget overseeding. The listed control period is 90-days. That's great if it does what you want it to do.

The other guy isn't the only one with success and failure using IMOX. If it's the same as what I use (never assume anything) - manufactured and packaged by the same company, then the use instructions are a little twisted because it's not labelled for crop use either. Another marketing gimmick and a way to obtain an EPA registration.

So, if you want to share your IMOX experience I'm sure there's a MM somewhere just itching to tell you where you went wrong and how to do it right!! LOL!
 
Wow! I doubt he needs you intervening on his behalf. He and I are both adults and able to fend for ourselves. He gives as good as he gets. You can read that anyway you want! I have the greatest respect for the man. Believe it or not, on another forum I shared some of his knowledge and named him one of the smartest men I've had the pleasure of counting and countering. As for your interpretation, nothing personal, but if you think I was over the edge, go back and read what you wrote. I'm a dick? I don't know you so I'll let it pass.

How am I supposed to know what you said about him on another forum? Yes, you did come across as a dick on THIS forum - the one that I moderate and try to keep things running smoothly and somewhat civil. Nevertheless, I apologize for misinterpreting your tone. Carry on.

Suggesting that chemical labels can be ignored on public forums is not good advice.
 
I'd like to see you try Thunder on your smartweed right when they are 3" tall, it's got a different active ingredient than Imox, and I've had amazing success with it.
Thanks. I'll definitely look into it. I don't live on my farm, so timing can be difficult. Pre-emergence treatment would be better for me.
 
Thunder is over $300 per gallon. Anywhere you can buy a quart?
Daniel's Farm Store in Leola PA, had it for $199 a gallon last season, they ship UPS.
Thunder herbicide has carry over, so it works similar to a preemergent, but it's recommended for weeds 3" tall, then you get continued weed control for a month. So you need to wait to plant corn and other crops after spraying Thunder. I discuss thunder on my thread KEYSTONE KROPS, bottom of page 1 and bottom of page 4.

To the OP. Have you asked yourself why is the smartweed liking your plot? Maybe it’s there as you force your plant choice in the soil. Indeed it loves wet areas. Maybe soil elements are deficient in an area that needs improved. Perhaps water retention and percolation needs changed. Look close. Use a shovel. Evaluate. Perhaps for a deer foodplotter one option is no chemical. Rotational planting can keep it in check. Hint.... smartweed is not a problem in grain crops.
BTW I found Imox works on smartweed but wasn’t overly impressed.
Good luck.

I purchased Pendulum last year but missed the window of opportunity to use it. So I used Imox later in the year. That with along with frequent mowing of my clover seemed to do the trick. My smart weed was over taking my clover. The other year when my wife said look at the pretty flowers in the clover. It was infestation after that. But I’m only really good at growing rocks. So take my advice lightly
