| After wheat, ahead of dc soybeans. Would mix with metribuzin (and gly if sharpen). Target weeds mainly pigweeds and some marestail, bindweed, and grasses.
Which do you prefer for effectiveness?
Sharpen will cost about $1 more per acre, but with the gramoxone I won't need the gly. But with sharpen there is a lot less material to handle when I'm usually in a hurry trying to get beans in the ground..... |

NWND | I would do sharpen and gly every day of the week and twice on sundays. |

| I have seen corn that was starting to tassle turn white all the way to the top from an application of gramoxone nearby that time of year. I would avoid using it when any crop is growing downwind for at least half a mile. It even turned leaves on the trees white. |

missouri | HERE sharpen and gly wont kill pig weed. Yes im using the required mso. it would be a no brainer to me to use gramoxone and crop oil HERE. |

| What time of year does sharpen fail for you? Even 2 ounces plus roundup and 2,4-d wont work here in July trying to kill pigweeds in wheat stubble. But for preplant burndown when it is cooler, and the weeds are smaller, like in april and May, it works great here at the 1 ounce rate.
Edit- just looked at the initial post and I agree sharpen probably wont work after wheat harvest. We used liberty last year.

Greenwood County, KS | Sprayer optill pro full rate with mso lastyear in late may on a field with heavy waterhemp escapes 4-12 in tall and in places it looked like it wasnt even sprayed. Other areas killed most all except the larger ones. Had to come back with paraquat, which nuked them |

Farmington, Mo | I would use Verdict instead of sharpen before beans. 5 oz rate of Verdict will give you 1 oz of sharpen and 4oz of outlook. Mix with gly, mso and a good residual will be a good program |

| Sharpen just doesn't work good on waterhemp or pigweed. Great product but not on that family of weeds. |

PROSPECT, TENNESSEE | I used a stiff rate of Verdict in some of my DC crop beans last year. I did great except for the huge ones cut off by combine. Also the variety of bean was a factor, with the rate of verdict I used.... didn't take notes...so just remember bits n pieces. |

NWND | Ok i guess location matters. HERE gly and sharpen will smoke anything you need too. I dont like gramoxone because it seems to just nuke the top part of the plant and doesn't get into the root system and the weed starts regrowing. |

Northeast Louisiana | We went with Liberty last year as well. Had fields eaten up with fairly large marestail in the wheat straw. Liberty got 95% of them. Not perfect but considering what it was up against I was satisfied. Came back with a post app and cleaned up the rest of them. |

| lol we are a long ways apart |

NC Kansas | Used Optill Pro last year to as a PRE on beans. Total failure. |
|
| |
|
Jackson County, AL | Ditto the Verdict. It's been better for us and does a great job. Will get some pretty big stuff and unless you have a weather factor for some reason escapes are rare. |

Sharpen vs Gramoxone?
