Have a few clients that don't want the normal chemicals used in the back garden because they're worried about their pets. Most are happy to keep pets clear of treated areas for an hour after spraying to be sure it's all dry but some want to take further precautions. I have used pine oil before and I'm thinking of trying Pelargonic Acid (Nonanoic Acid) - 'Slasher' now.

I'm wondering if anyone in the forum has used both and would like to comment on the relative effectiveness of each. Will check Globe Growing Solutions prices tomorrow but as a guide for now, Slasher is $86.90 fof 5L at Bunnings and Pine Oil ('Weed Blitz' - Amgrow) is $381 for 15L. Dilution rate for backpack for Slasher is 70ml per litre. Can't remember dilution rate for pine oil.
