Botrytis, leaf-curling midge and sawfly are economically damaging diseases and pests of blackcurrants. Botrytis not only causes grey mould of the fruit but can give rise to "run-off" in spring, leading to reduced yields. Leaf-curling midge stunts growth in shoot tips, slowing bush growth, while blackcurrant sawfly can lead to defoliation of the bush.
