Treatment : Otiorhynchus larvae

larve othiorynque

This small white larva or worm, also known as a weevil, nests in the roots of flowers, ornamental plants or vegetables.

Although not considered a life-threatening attack on the plant, aggression by a large population over a long period of time can become dangerous.

How is the presence of this larva in the plant characterized?

Small insects, such as white maggots, lodge at the roots to feed on the rootlets and crown.

They will thus gradually dig narrow galleries, destroying the root system and limiting its development by weakening the plant.

How do we fight these grubs?

There is no treatment that is actually intended for the control of otiorhynchus larvae.

However, some recommend spraying a treatment normally intended for vegetable maggot.

More difficult to find, but having proved to be effective, the presence of nematodes can help to eliminate this insect.
Use only for pot cultivation, as it is a pest for many guests in your garden.
