Wielkopąkowca is difficult to fight in the period when it is hidden in the buds(autumn - winter). It is recommended to inspect bushes in the leafless period and remove excessively enlarged, spherical buds, cut shoots with the largest number of damaged buds, and if necessary remove entire bushes.
Spraying large currant can be effectivein the period when the pest leaves the buds and comes out to feed on the underside of the currant leaves. This takes placein May, during the currant flowering period Pests can feed on the leaves until July and even the beginning of August.
