nema-green® against June beetle grubs
nema-green® contains the nematode species Heterorhabditis bacteriophora. This species specialises in June beetle grubs, among other things, and can use them for its own feeding and reproduction. The nematodes are supplied alive in a powder. For application, they should be mixed with water exactly according to the package instructions and applied to the affected areas.
Damage caused by summer chafer grubs
The main damage is
caused by June beetle grubs in the 3rd larval stage. They feed
underground on the grass roots, hindering water and nutrient uptake by
the plants. June beetle larvae cause brown spots in the turf, the turf
is easily pulled off, masses of grubs appear; dry turf in places.
Birds
and other animals (e.g. wild boars) also destroy the turf by pecking
and burrowing in search of the tasty grubs. Infestations include private
lawns, public green spaces, sports turf, and golf courses.
