   Anyone else testing/trying Arysta's new product Xonerate for Poa control on Bentgrass? If so, what are you seeing?

   We did some testing for U.C. Riverside with both Amacarbazone and Methiozolin. We had several plots set up on our # 2 green. I chose the green because it had the highest % of Poa on the property. We had combinations of Xonerate with Methiozolin at various rates and we had each applied straight at different rates and application frequencies. It was clear very early on that among all the other combinations of other products in the trial that something pretty good was going on with the two new compounds. We found that at higher rates, Xonerate (Amacarbazone) posed a little more risk of working too fast and leaving some voids that bent couldn't fill in quick enough. I am sure they refined the rate and frequency to reduce that risk. I think both compounds will provide some strength to a Poa control program that we have not yet experienced. I am sure it will be a yearly ritual rather than a one time total cure. I am anxious for both to eventually get California registration. Look for long term results. It isn't somehting you apply today and Poa is gone tomorrow. The recommendation in SoCal will be applications beginning in mid to late October with about 6 applications at designated frequencies.

   Xonerate: 2012
   I will finish my 4 week test this week on greens and Fairways Bent greens, Zoysia fairways. Poa is just fading away with no brown out at all, On the fairways I did 2 ap's at 2 oz per acre and greens were 1oz per acre 4 times. I also do one fairway test at 3/ 2oz/A test and it looks the same as the 4 oz. I think we may see 80%+ control.
   I also did a treatment with Mach 1 a Japanese chemical with maybe 60% control so far. Cost of that one would be $1000 per green. Cost of Xonerate is $114 per green average. High but it works.

   I'd like to ask anyone using this product if they have to be carefull with spraying across greens and not overlapping into the surrounds? My greens are bent, surrounds contain KBG and Fine Fescues. My experience is that the fescues are pretty intolerable to alot of the specialty herbicides and other poa control measures. What are the feelings of my peers?

   Kyle,
   
   While at Oregon State I did some trial work with this product on 10 cool-season turfgrasses. All of the FFs were dinged by it. The trials were on 0.5" and 2" turf. I would be cautious and curious to hear from others on their luck with it near FFs? It also dinged up the colonial and velvet bentgrass a bit.

   I have no experience in what you're asking, but I've been told "DO NOT" spray in the fall. Turf with shortened root systems will be injured!

   Personally, unless you are absolutely sure of your population of bent, I'd wait for someone else to be the Guinea pig. How many times over the years have we heard of some poor supt. spraying his greens to take out Poa only to find out his population was much higher than he thought?

    We have recently worked with a small sample, applying it to our green surrounds. We found it completely cleaned out the Poa but also took out any bent encroachment growing out from the collars. We specifically did this in a period of high 90's with a couple of days topping 100. Obviously, you would never treat greens with these temperatures but it did do what we hoped for on the surrounds. If I can obtain a little more, I will try it on our bent nursery in cooler temperatures.

    I am in Las Vegas and have tested the product on 3 different putting greens. An A4 with no poa, an L93 with a hand full of quarter sized patches of poa, and a dominant plus green with 40-50% poa. I went @ 1oz/A every Thursday for 4 weeks. On the L93 green we saw some light discoloration over the entire test plot and the small poa patches were severely injured. On the A4 we saw slightly more discoloration but no permanent damage to the bent-grass. The plot on the dominant green was a total loss and will have to be sodded. Some patches of perennial poa were totally unharmed, it possible that there was more poa annua than we originally suspected? Yes, but it absolutely hammered the dominant bent-grass as well. We made the applications throughout October, as far as temps go, our lowest low was about 46 and our highest high was about 84. My conclusion is that it definitely has varying effects on different varieties of bent-grass and I would highly recommend running some tests before you go wall to wall.

    I tried it under experimental use on a fairway in the spring of 2011. A week after the second application temps warmed into the 80's and bent and poa both turned brown. Most crowns survived but overall it looked ugly for weeks and the low area took more than a month to fill itself back in. Poa greened back up as fast or faster than bent. Sand drainage trenches fared better leading Arista to suggest clay soils may have been the problem. University friends suggested the my rate 3 0z/ac was high, but that was the rate Arista suggested. I think label rates are different. Bottom line be VERY VERY careful. On Declaration fairway height bent.

    Is there any solid research for these two chemicals when it comes to climate/weather? i.e., Daily highs and lows, relative humidity, sun/shade, soil temps, vwc, etc. It seems that there are so many factors that may skew overall results that it would be impossible to explain either positive or negative results. Considering grass type, are there ideal conditions in which to apply? If so, then why or why not. I've heard of some experiencing great results, and I'm also hearing of people losing the turf they were trying to promote. How many of you feel that the benefits outweigh the risks, or vice-versa?
