Damage caused by welsh chafer larvae

Direct damage is caused by welsh chafer grubs, which feed on grass roots underground, thereby hindering the plants' uptake of water and nutrients. Indirect damage is caused by birds and other animals (e.g. wild boars, badgers) which destroy the turf by pecking and digging in search of the tasty grubs.

nema-green® against welsh chafer larvae

The nematode species Heterorhabditis bacteriophora, which is contained in nema-green®, specialises in grubs, among other things, and can use them for its own nutrition and reproduction. The nematodes penetrate the grubs and secrete a bacterium that kills them.
