Bay sucker can spoil the appearance of a bay tree by causing discoloration and distortion of leaves at the shoot tips.
Common name Bay suckerScientific name Lauritrioza alacrisPlants affected Bay (Laurus nobilis)Main symptoms Leaves develop curled leaf margins that are abnormally thickened and pale yellow. Greyish white insects may be seen under the curled leaf margin. Later the damaged parts of the leaf dry up and turn brownMost active May to October
Bay sucker is a small sap-sucking insect that attacks the foliage during the summer. It is the nymphs that cause most of the damage.
Bay sucker can affect the appearance of bay but does not usually reduce the vigour of bay plants.
Pesticides for gardeners (Adobe Acrobat pdf document outlining pesticides available to gardeners)
The damage is caused by the nymphal stages of the bay sucker when they suck sap from the young leaves during the summer.
