How long will Spinosad spray keep after mixing

I just mixed up two gallons of Surround and Spinosad to give my fruit their first spraying of it for the year, now that most of the blossoms are finishing up and tonight’s low is supposed to be 58. The rain was supposed to be over. As I stepped out the door to go spray, it began to rain again. Does anyone have any idea how long the mixed spray will keep?

Good question. As I understand it distilled water gives you more storage life, but who knows how long? When I faced this problem I ultimately ended up deciding it was not worth risking my crop to save two or three bucks, so I’ve gone to the “when in doubt throw it out” standard.

The rain didn’t last, so I was able to use the spray yet the same day.
