    In reading the article linked below, I am curious as to what my chances are of obtaining either of the products, called Callisto® made by Syngenta or Balance Pro® made by Bayer. Can I call company reps and purchase it? Will they sell to unlicensed homeowners?

    Or can a local LCO obtain these and apply it for me for a price?

    I am desperate for a selective control for creeping bentgrass in my KBG. I already killed the entire turfstand once last fall, reseeded and am now finding that there are spots of the bentgrass coming back. These products are not yet registered for turfgrass applications but seem to show great promise in selectively controlling perennial grassy weeds in cool season grasses. Thanks.

    Generally, bent cannot tolerate high (high meaning the highest rate on the label) doses of 2,4D. Repeat apps will usually do it.

    Thanks Mike. I'll have to try that. Would it have to be straight 2,4D, because I've experimented with weed-b-gon on it and I don't remember much of an effect?

    I don't know about Weed-B-Gone. I've used Trimec with decent results.
