How to use nematodes correctly

Early control of black vine weevil

The black vine weevil belongs to the weevil family (lat. Curculionidae) and is a blackish beetle about 1 cm in size. The black vine weevil is light sensitive and nocturnal, during the day it usually hides under leaves, foliage and the like. It is a common pest of more than 100 plant species such as yew, rhododendron, cherry laurel, and privet, as well as strawberries and roses. The main damage is caused by its larvae. With our product nemamax®, the larvae of the black vine weevil can be controlled biologically and effectively from as low as 8°C soil temperature.

How do nematodes work?

Nematodes are about 0.5 mm long, of which there are over 20,000 different species worldwide. The species Heterohabditis downesi is specialized and particularly effective in the control of nematode larvae and grubs. The nematodes penetrate the larvae, where they secrete a bacterium with which they live in symbiosis. The bacterium kills the pest and the nematodes multiply inside it until it is consumed. The nematodes then move on to infest the next pest. This process repeats until all pests are controlled.
