How to recognise it

Damage: Where damaged, the leaves lose their colour or turn bluish-pink and become deformed.

When to look: The greatest development and spread of the aphid are recorded during oilseed rape flowering.
On spring oilseed rape it damages plants at the rosette formation stage.
In autumn the aphid colonises winter oilseed rape plants.

No rate and no spray timing here: both come from the label and the register.

Agronomy: Destroy cruciferous weeds and post-harvest residues, and carry out deep autumn ploughing.
Plant cabbage next to tomatoes, which repel this pest.
Biological control: Seed plants of umbellifer crops (carrot, dill, phacelia), which attract natural enemies of aphids, should be placed near the cabbage.
Against this aphid, a continuous succession (conveyor) of nectar-producing plants is set up.

Overwintering: Aphid eggs overwinter. Good overwintering of the eggs is recorded every year.
Natural enemies: Among the predatory natural enemies of aphids, the most important are syrphid flies, ladybirds, lacewings and spiders.
Entomophages limit the aphid and hold back a rapid increase in its numbers on spring oilseed rape crops.
Where it is found: It develops everywhere in oilseed rape crops throughout the whole growing season.
