Sorry about that - I use the term 'pesticides' to include

apologise for any confusion. In this context, I meant weedkiller,
specifically one not fatal to lawn grass.

You are correct in your use of the term "pesticide". It is a
general
term that includes herbicides, insecticides and fungicides. Weed
killer
is a herbicide which then means that it is a pesticide.

You may use it in that way but nobody else I know does so.
Herbicide is not
pesticide. We do not use pesticides on this nursery but very
occasionally
we use herbicides. As we use biological controls in the
greenhouses, the
difference is very marked and it would be sloppy to encourage people
to use
'pesticides' when one might mean 'herbicides', IMO.

According to the Encyclopedia Brittanica, a pesticide is "any toxic
substance used to kill animals or plants that cause economic damage to
crop or ornamental plants or are hazardous to the health of domestic
animals or humans." It goes on in a vein which *explicitly* includes
herbicides, insecticides, fungicides and fumigants.

Herbicides are therefore included in the term "pesticide".
