I really hope I get some answers to this…
I’ve read many times that you shouldn’t let most spray chemicals sit after they are mixed, but I’ve never heard what time period that becomes an issue and things loose effectiveness or whatever happens.
At this moment, I’m in a dilemma. It’s bright and sunny all day and I just mixed up 25 gallon of spray. And of course Murphy shows up…I literally finished putting the lid back on my spray and I notice the sun has gone away. Minutes later, thunder. forecast was sunny all day so I look at radar and sure enough- one big thunderstorm is bearing down on my. Its not huge- probably won’t last an hour, but it will be 1.5 hours or so before it gets here.
This happens to me more than I can believe and may have happened to others so it would be nice to hear some thoughts on what to do in these cases (or when anything else happens after you mix your spray). Should I go ahead and apply the spray knowing its going to be pouring rain in about 1.5 hours? Or should I wait for the rain to come and go?
Here is what is in my 25 gallon mix:
Imidan 70 insecticide
Pinene 2 sticker
I know some of these things may seem repetitive but this is what I do on my first couple sprays and it works for me and I’m happy with it even if some think I’m duplicating - so that isn’t the focus of this question.
So, how long do you think I (we collectively) can let this mixture sit before it is a problem? AS you can see, there is a lot of money in that tank and I’d hate for it to go bad, but I also hate to apply and a thunderstom get here before it even dries. THanks
