@blissful I was surprised at how long that Surround lasted me! But the way I use it helps keep it a long time - I use 1½ c/gal, and use a dedicated 2 gal sprayer for this, and some potassium bicarbonate, as a preventative fungicide, plus a spreader/sticker. And these things I leave in the sprayer until I need it the next time, and usually I am only spraying the new growth, so not a whole lot is used. After the heavy rain, like I'm getting today, I'll be spraying a lot more, but the undersides keep it on, and with light rain, not much washes off. So it's not very often I refill that sprayer, with the 3 c of powder.
And something that I do with it, that I learned to do early on, is I place a fine strainer on top of the sprayer, and put 1/2 c powder at a time in it (I actually put the potassium bicarbonate in first, which dissolves as I do this), and wash the powder into the sprayer, and continue this, until the 3 c are in. Some "pellets" of powder can be seen, doing this, and they dissolve through the strainer, yet just added directly to the strainer, I would have trouble with clogging - yet when washed through, nothing was there! There's also the occasional particle of something else, but that's trapped, too. I do that now with everything else, when loading sprayers, to avoid clogging.
