BT Insecticide, where to buy?

[cidley69]

Anyone know where to buy Dipel, Foray or Thuricide insecticide, in Calgary area?

Maybe at a farm supply store?

Something with Btk? Rona? Home Depot? Sunnyside? They all sell it.

All those places sell is 100ml containers, I have lots of big trees , hoping to find more cost effective size container of it.....
