    We add quicksilver to threeway for a little boost. Only in the spring. Quick burn down and customers can see the weeds dying. No service calls saves money. Old customers are spot treated new customers get a blanket treatment if needed. It's worth the extra cost not having to explain to customers why weeds die slowly in cold weather.

    I use it anytime I am spraying for broadleaves.

    It not only gets several hard to control weeds...but also speeds up the kill dramatically.

    It depends on how you value your customers!

    What I mean is....I don't pass on the additional cost of the prouduct to them...so it is really an "added service" to me. Some people give away "free" aerations or application, and I just give my customes AWESOME weed control.

    Not sure if it is worth the price, but when talking to new customers, it can help make a sale!

    From what I have read in studies (and I have no experirence to validate this info personally), carfentrazone is the most effective control for wild violets in the tool box. When I do my first broadleaf spray control late next week, I will use a 3 way spiked with Quicksilver. Should take 2 apps to get good control as I understand. I will supplement with hand pulling after 2 apps.... I'm an IPM LCO that sprays.

    I'll comment on results as I go.

    BTW Rodney, the gly app DID put a hurt on that Engish Ivy. I'll up the dose, and hit it again this week. It's been hurt, no doubt. About 40% of the foliage is affected. I'll go max rate on this next round.... and then get ready for physical removal in another 3 weeks. Then I'll hit the area with Sahara. It's mostly behind a garage.... next to a town water basin, so the Ivy will come back sooner or later. I can only hope to win battles with this thing, never the war.

    I've tried it before...just like tlg does, as a little "boost" to Trimec, Triplet, etc...

    But even as a "spiking" agent it can really aggravate already stressed-out and /or dessicated turf that's going through drought; so extra care should be taken in those instances to avoid non-irrigated turf, especially.

    All in all...the math....and the overall results still tilt in the favor of 'Cool Power' (and before that...'Three Way Ester II'); at least from the prices I've been able to negotiate in the last few seasons.

    I will agree with that. Quicksilver will burn up dry turf. Then again, I will not apply ANYTHING to a lawn that is not correctly irrigated and fertilized. Too much liability for me. Besides, weeds that are half dried tend to shrug off herbicides anyway. I love going after weeds when it was raining the month before. They are so much easier to kill.

    If a lawn has mostly 2,4-D susceptible species, I will use 1 lb ester + 1/2oz Quicksilver. It is cheap enough and I get results that the guys spraying Trimec amine do not see. For what I charge per M, I would be advised to produce dying weeds within 48 hours.

    Is there any reason why you are not hitting the ivy with Garlon or 2,4-D? I will never use glyphosate if my target weed is a vine of some kind. As I have mentioned in past posts, I often deal with vines that think RoundUp is MiracleGro. They do go down if I spray ester or Garlon 4. Another good herbicide for vines is metsulfuron, sold as Blade for turf and Escort for IVM/nonplanted areas. If Sahara can be used, metsulfuron will be ok as well. In fact, Sahara will take out existing vines if sprayed with a methylated seed oil surfactant.
