Nemasys Vine Weevil Killer

Nemasys Vine Weevil Killer is the simple solution to control vine weevil.

Apply to pots and open ground March to May and August to November. 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 pest from feeding, quickly killing the pest. 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.

Nemasys Vine Weevil Killer is available in pack sizes of 160 pot or 12 sq.m/14 sq.yds or 100 sq.m/125 sq.yds.


Mixing and applying your nematodes

Use entire packet at one time and do not store part used packs or made up solution. Nematodes are easy to apply simply as a drench. All you need is a watering can with a coarse rose or a recommended hose end feeder. A standard pack takes approximately 20 minutes to apply.

Once mixed with water, apply immediately, making sure they are applied to the soil. Wash any nematodes off the leaves using more water.

It is important to water the lawn thoroughly immediately after applying Nemasys Chafer Grub Killer and Nemasys Leatherjacket Killer. This is to ensure the nematodes reach the soil where the target pest is located. Make sure the lawn does not dry out after applying nematodes.

Watering can method
