Gooseberry sawfly
From spring to summer, wasps eat the leaves of the plant and often leave only a leaf skeleton. Put an infected leaf under a magnifying glass, recognize the small larvae.
Collect the larvae by hand or tear off the whole leaf.
Blasenlaus
The bladder louse causes discoloration of the leaves. With red currants the leaves turn red, with white and black varieties they take on a yellowish coloring. Bubbles form on the top of the sheet.
If infested with soft soap or other home remedies, spray the plant against aphids. Stinging nettle has proved very useful here.
gall midge
The name of this pest is completely blackcurrant gum mosquito. He only appears on blackcurrants. The leaves curl up and the shoot tips wither away. This is due to small larvae that are difficult to combat.
Cut off all affected shoots and remove rolled up leaves.
eriophyidae
Here the infestation is already recognizable in spring, when the buds are unusually swollen. As mites evolve, they form galls, small bumps on the leaf. The buds die, the leaves deform and eventually fall off.
If infested, spray the plant with tansy mud every week. Cut off all affected parts of the plant and collect the fallen leaves and buds.
clearwings
This is a butterfly that drops its larvae in the shoots. They feed on the shoot and let it die.
Diseased shoots are cut out. A spring net spread in the insect prevents the butterfly from laying its brood on the currant.
Tips & Tricks
Basically, it can be said that strong, healthy currants handle most pests well. Spray the plant more often with nettle stock. This strengthens the leaves and limits the feeding damage of lice, mites and caterpillars.
