• Nemasys Vine Weevil Killer is the simple solution to control vine weevil.
• Apply to pots and open ground from early March to late October. This is when the vine weevil larvae are present and the soil is above 5ºC (40ºF). If applying under cover the pest's lifecycle is broken and Nemasys Vine Weevil Killer can be applied at any time, as long as the soil is above 5ºC (40ºF). Apply directly to the soil around the roots, which is where the larvae will be feeding.
• To keep a minor problem at bay, one autumn treatment should be adequate. However, for a serious infestation, treat in the spring and again in the autumn. When treating pots take care that the pots are not allowed to dry out.
• The nematodes (Steinernema kraussei), seek out the vine weevil larvae and attack the pest by entering natural body openings. Once inside, they release bacteria that stops the larvae from feeding, quickly killing it. They do not stop there. The nematodes reproduce inside the dead pest and release a new generation of hungry infective nematodes, which disperse and search for further prey. Nemasys Vine Weevil Killer will kill larvae present in the area and protect against further larvae damage for up to four weeks.
