Prime Source PPZ 41.8 Fungicide would not be recommended to use in a hose end sprayer as the rate is not set per gallon but is per area. Water is just the carrier so you use the labeled rate in however much water it takes you to cover the 1000 sqft. Since we do not carry that model hose end we are unfamiliar with it or how to set it and cannot advise on it. You can try reaching out to the manufacturer of your equipment or Prime Source who can be reached at 877-235-0043.
No, Prime Source PPZ 41.8 Fungicide does not need to be applied with a surfactant.
You could potentially use a surfactant that is labeled for use with fungicides, such as Hi-Yield Spreader Sticker with the Prime Source PPZ 41.8 Select Fungicide. However, it is not required to use a surfactant with this fungicide. The product should have time to dry completely before rainfall, although we recommend applying fungicides when you are not expecting rainfall for at least 24 hours for best results.
