Did you know that untreated Black Vine Weevil (Otiorynchus sulcatus) larvae can devastate your crops in just a few months? These pests pose a constant threat to ornamental nurseries, often arriving from various sources, including bought-in plants. Once on site, their numbers can build rapidly, causing significant damage if not controlled. The real danger lies in the larval stage, where they cause serious plant damage by attacking the roots and stem bases. After hatching, vine weevil larvae move through the media, feeding on healthy root tissue and compromising plant health.
What is Nemasys-L?
Nemasys-L (Steinernema kraussei) is a curative treatment of microscopic nematode worms that, once applied, will seek out Vine Weevil larvae in the soil and compost. They enter the larvae and release a small pellet of bacteria to kill the host after a few days. The parasitic worms begin to reproduce and release several thousand more juvenile infected nematodes able to find and further kill Weevil grubs.
Benefits of Nemasys-L:
Effective Control: Targets and kills Black Vine Weevil larvae, preventing root damage and plant loss.
Cold-Temperature Tolerant: Functions in soil temperatures as low as 5°C, making it suitable for use in various climates.
Long-Lasting: Provides protection for up to 4 weeks after application.
Safe and Natural: A biological solution that poses no risk to humans, pets, or the environment.
Available in Small or Large Pack Sizes: Choose from 50 million or 250 million packs to suit your needs.
When to apply Nemasys-L?
Apply Nemasys-L when Vine Weevil larvae are present in the soil, typically between March-May and again in August-October, although additional treatments may be needed for heated or protected crops.
