    The part about how long it takes for activity in cool weather is the main issue, I think. It also looks like Bayer saw this and made a thinly veiled attempt to correct it. Look at the 3 active ingredients in Celsius:

    Iodosulfuron: an ALS inhibitor (which are notoriously slow in cool weather). WHen you dig into the physiology, as soon as Iodosulfuron is taken up into a plant, it is metabolized into metsulfuron, water, and carbon dioxide. So, it's no different than applying Manor, except that it's more expensive.

    Thiencarbazone: a PPO inhibitor that causes some contact membrane disruption. This one's no different than carfentrazone (Quicksilver), but a lot more expensive.

    Dicamba: You'll see this carboxylic acid in most of your standard 3-way mixes, since it has reasonably quick activity on perennnial weeds and legumes (think dandelions and clovers) in cool weather.

    To get the same spectrum of control, you could mix your own Manor and dicamba for a lot less money -- or you could add your own PPO inhibitor of choice to get the quick symptomology you're looking for.

    I have not, but personally I am not all that opposed to a slower kill. When I can run one herbicide in the early Spring and kill more than just some easy broadleaves with something that seems easy on the transitioning Bermuda and especially St Augustine I do not mind waiting a couple of weeks.

    Mainly my Permagreen and also my engine driven backpack with two AI nozzles. At the moment my Permagreen is down and also the backpack so unless I get the PG going it looks like I will be using my skid, but I am very tempted to order the Tee Jet Widejet gun [I think that is what it is called].

    What happened to the engine drive backpack? That was the Maruyama clone, right? I have a boomless nozzle that I hardly use. The spray pattern is nothing like a set of fan nozzles on a boom in terms of consistency of spray deposit and drift control. I have used this set up for straight fertilizer and non crop herbicides in wide open fields. Not really something I would trust on a lawn that cannot be yellowed or marked up. Celsius is pretty forgiving on lawns, but I am always nervous about what is downwind of it. If iodosulfuron metabolizes to metsulfuron :eek: flowers, trees and shrubs are in danger. On big lawns, I feel much safer using the skid sprayer to power my 3 nozzle boom. If they are big enough to drive on, they are done with the 10 ft boom on the truck.

    This what kills me, 90% of applicators have no idea how theses products work.

    That's why we read and learn. No one starts out knowing what it's all about. Some may not take the time to learn right, but there is no stupid questions when your wanting to do things the right way.

    Also, most of the tech knowledge is and should be up to the manufacturer, then we in turn use the products that will do what we need. A race car driver doesn't have to know exactly makes his car run fast.Thumbs Up

    I am going to have to agree with winstarblazer on this one. I try to suck up as much knowledge as I can here on LS. I am tryin to intern with a guy that has a squirt and fert down here near me, but I do have a full time job that I am obligated to and he doesn't work weekends from the looks of things.
