It assessed three scenarios across 51 horticultural, arable and forestry sectors, and showed losses ranging from £905m to over £3bn.
- Scenario One looked at the loss of 10 fungicides, three herbicides and four insecticides. With production losses totalling 2.4m tonnes, this would have the largest impact on the horticulture sector, with losses valued at £430m or 26 per cent of farm gate value.
- Scenario Two includes an additional 11 fungicides, seven herbicides and two insecticides, with edible horticulture accounting for the largest proportion of the estimated 5.7m tonnes of crop losses.
- Scenario Three includes an additional 29 active substances lost, yielding food production losses put at 14.2m tonnes across all sectors.
HDC head of research and knowledge transfer Dr Jon Knight said: "The potential impacts are particularly severe for horticulture because the reliance on Extensions of Authorisation for Minor Uses [EAMUs] for a range of actives means there are fewer alternative products available for filling any gaps."
