Box hedges and topiary are often affected by box sucker, although the damage caused is not usually serious.
Common name Box suckerScientific name Psylla buxiPlants affected Buxus sempervirensMain symptoms Leaves at the shoot tip are cupped. In late spring, flattened pale green insects and a white waxy substance are presentMost active April–early June
Box sucker is a sap-sucking insect, also known as box psyllid, that feeds at the shoot tips of box plants in spring.
Box can suffer from a number of other problems.
Damage from this insect is usually superficial and control is not usually necessary on established box hedges or topiary plants that are going to be clipped.
Regular clipping helps remove affected parts of the plant.
If damage is serious to plants that need to grow larger they can be sprayed with insecticide.

good morning everybody, we have few attacks on Buxus this month in France (south west). we use organic deltamethrin to fight it. Our major problem is the Glyphodes Perspectalis, a caterpillar which cause damages on buxus.

Bonjour - I live in the south east of France (Nice) and will now look at the buxus I've planted here. Hope you can solve your caterpillar problem. This disease affecting buxus is a huge problem in other parts of Europe but I've not heard of it here so far (fingers crossed). Does the organic deltamethrin seem to be doing the trick?

bonjour, good evening, organic deltamethrin is a good tool to fight differents pests on buxus even though the "bacillus thuringiensis" is the best solution to fight caterpillars. Traps with pheromones are really effectives.
