No conflict of interests on pesticide advice | Letters

The assertion by Professor Dave Goulson (Farmers could slash pesticide use without losses, research reveals, 6 April) cannot go unchallenged. He says that pesticides are massively over-used because farmers are advised by agronomists working on commission to sell products.

The Agricultural Industries Confederation represents the majority of businesses that supply both agronomy advice and crop protection products to UK farmers. Farmers can elect to pay separately for agronomy advice and crop protection products. Farmers also have access to information from agrochemical manufacturers as well as independent agronomy research organisations - much of it free online. In many instances, those delivering advice do not receive commission.
