    I'm trying to understand this unit. Seems people use it for mosquito spraying fogging. Can it also be used for spraying shrubs or even lawns? If so how? I'd like to use it for insecticides fungicides etc.. But I can't seem to find any mix rates etc. Help:dizzy:

    That is close to the same as a Solo 450 mist blower. I do know about those. Many use them for treating shrubs and trees, turf for that matter too. Mixing rates would be on the label of the product your using.

    IF you dont know about mixing are you certified pesticide and fertilizer applicator?

    Mixing is on the bag. If you cant find this it leads me to believe you are not a licensed applications specialist?

    Mixing is on the bag of what?

    I think they want to know how to use the mist blower. I don't see where they list a product being used, just says insecticides and fungicides. May be they want help with a product suggestion also?

    Where do you people come from. This is a question about mist/foggers. Why are so many idiots obsessed about policing others on an open lawn forum. It really gets old. I've been licensed and certified for nearly 20 years. For the past five years I've been teaching pesticide safety; Toxicity. LD50's, PPE etc. My question about a mister comes from the assumption I could use less pesticide due to the smaller droplet size ( similar to the Herbi sprayer) thus being safer to applicater and the environment. I don't know everything and I love to learn more as well as share my knowledge with others. I find too many "policing posts" stifle the eager to learn.

    I'll try and find you more information if I can. I figured you were looking for specifics on mist blower applications.

    I have 1 of these and also have the granular attachment for it.
    I use it for a foliar spay as well as turf.
    In the manual there is a 2 page formula for calculating mix ratios.
    If you go to Stihl's home page they have a link for manuals.
    It suggest to fill it with water and do a test area since no one walks at the same pace.
    There is an adjustment at the end of the sprayer to control the flow output from 1 -6
    I spray all organics and havent had a problem.
    There is also a flow control for the granular that is less sophisticated ..you just close off the hole by rotating the throtle right to left.
    hope this helps

    He clearly asked fo mix ratios in his first post. Learn to read! and piss off, if noone polices' you landscrapers, god knows you wont do it your selves. With your non belief in PPE, and that awesome trick you do topping hedges and shrubs with hedge trimmers.

    Great arboricultural/horticultral practices!
