Does anyone know how long the companion wettable powder will stay good for (or at least still worth using) once its been opened?

I've always wondered the same?

I hope this helps - it is not as easy as I'd have expected, lol:

Thanks Pumpkin pal! i am surprised that it would remain viable for so long. I wish they would specify if that means Greater than three years even if it the container is opened. Most biological stuff seems to go quickly once opened. Kind of like opening a can of food, or a mylar seed package, once its opened, it's shelf life really gets cut down.

I found this link too, it is super helpful and is like a crash course on biologicals. https://ipm.cahnr.uconn.edu/wp-content/uploads/sites/3216/2022/12/2020biologicalfungiciderevfactsheetfinal-2.pdf

I've been thinking about the fact that I keep my seeds in super-sealed Mason jars with no desiccant and my seeds from other growers in gallon jars used for pickles at a deli, that are no longer really airtight, which may equate to many years of seeds' viability being lost therefore. Dum on my part and in need of an annual trial for any seeds of heritage and notoriety to see IF they'll still sprout with my merely 'hopeful' efforts; A Germination Fridge is SO helpful, right in my garage.
The point? Ooops! Perhaps vacuum-sealing our seeds abroad and such things as valuable chemicals and biologicals in airtight - and airless-as-possible - containers is to be investigated. I don't think it'd be difficult and there were plenty of articles about it that I had to stop myself from reading too much of...lol. I'd have to worry slightly about if a 'biological' - or a pumpkin seed or other - withstands vacuum. I saw something about an oxygen absorber to be included in or with the process... I'll think of it as I open a jar of apple sauce or...recently, ooohhh, Orange Marmalade! eg

Here's a quick thought - you run a tank of water through a pump that is cranking 60 psi in the output. Imagine that the tank is sealed and the pipe to the pump is solid metal. Before any collapse, I'll bet that the vacuum in the container is negative the pressure of the output, or at least (Enough? Negative enough, lol?)...that I would not want my hand over any part of it... I'm hungry - all this food for thought! Happy Turkey Day, everyone! eg

Yes, all that stuff explained & listed out in chart form - very convenient for our future referring to. eg

Thanks Big Moon for that link on biologicals. As we discussed about the disease in my patch, I am hoping it isn't over wintering in the soil and is a "one off" that left with the plants since biologicals need to be used before infection.
