I am not an 'absolutist' but I have seen bees taking pollen from Provado treated plants and dropping dead almost immediately. They did change the formula so it is not as deadly as it was, but since we have spent 20 years building up the bee polulation in this garden, I am not going to take any risks.
We find now that we rarely get any major infestations of anything as the garden seems to be in reasonble balance.
I do use weedkiller, very carefully as there seems to be evidence that it is not broken down in the soil as claimed.
I soray my fruit trees with an Insecticidal soap and later on with Copper sulphate. Will do the potatoes with it as well. But only when the insects are not around.
