    For those who use skid sprayers, what gpm nozzles do you use? I see that Lesco carries 1.5, 2, 3, and 4 gpm choices. I bought a 1.5....will this be adequate for most liquid applications?

    I always applied at 2 GPM (just because you have a 2 gpm nozzle on does not mean it's coming out 2 gpm! Check your pressure and verify). I started this year at 1 gpm out of a 4 gallon back pack (with a 25 gallon nurse tank soon to come). I got tired of the refills, and doing the blanket apps. Be careful at the lower rates because you will be alot more concentrated. Also keep in mind that some pesticides go down better at a higher carrier rates.

    Different application call for different rates.

    Insecticide soil drenches cal for alot more than broadleaf. I would say if you are new to spraying and are doing a typical broadleaf nutrient mix -- 2 or 3 gpm is a good start. Marko gave good advice on calibrating though - you can easily get 4 - 5 gpm out of a 2 gpm nozzle with enough pressure.

    Hey Lonnie,

    You like this answer:

    Buy the yellow nozzle for killng weeds.

    Need white for fungicides and insecticides, depending on chemical.

    Correction... .5 gal/min (2 minutes to blanket 1000 sf) which is rare to do a blanket app except on a new customer that was previously a dandelion farmer

    I suppose that I will be fine as long as I am within the perimeters of the label directions...
