Pesticide usage in Scotland: arable crops and potato stores 2020

This publication presents information from a survey of pesticide use on arable crops and potato stores in Scotland during 2020.

(1) Includes nematicides

(2) 92 per cent of legumes in 2020 had no seed treatment; the seed treatment information for the remaining eight per cent was unspecified

Note: STs = seed treatments

The average number of spray applications is calculated only on the areas receiving each pesticide group and therefore the minimum number of applications is always one (see Appendix 3 – definitions and notes for details)
