Use of nematodes in tree nurseries

Vine weevils

The key pest for tree nurseries is the black vine weevil, Otiorhynchus sulcatus. In addition, other species of weevil such as O. ovatus, O. crataegi and O. armadillo are increasing in occurrence. With only a few exceptions, they are also vulnerable to our product nematop®.
The product nemamax® controls Otiorhynchus sulcatus, O.armadilli, O.dieckmanni, O.rugosostriatus, O. salicicola, O.smierczki and O.ovatus in nurseries and Hylobius abietis in forestry.

nemamax® and nematop®

nemamax® is effective at lower temperatures, soil temperatures should stay above 8 °C  for several hours the day. Therefore it can be applied in early spring and late fall.
Cooler night temperatures do not damage the nematodes, rather, they are inactive during this time.
