i hav e some fumidel b and terramycin left from last year. it has been kept in refrid. will it still be good. also i have some pollen substitute that also not used and kept in the frid. is it ok? colvin
I've always heard that pollen substitute is best kept in the freezer and thawed out over night in the fridge.
Terramycin has an expiration date on it. As long as you have kept it in a cool place and a pretty much airtight container you are Ok. I don't have a bottle of fumidil right now to check that for you,maybe someone else here has that info. TM 25 is usually under $5.00 U.S..so it won't hurt to much to buy a fresh batch of this every year.
