Nemasys C is a powerful and environmentally responsible solution for controlling pine weevils, caterpillars, and shore flies (Scatella stagnalis) using the beneficial insect-parasitic nematode Steinernema carpocapsae. Suitable for both soil and foliar applications, Nemasys C is designed for use in a wide range of horticultural, forestry, and landscaping environments.

Once applied, the nematodes actively search for larvae in the soil or on leaves, penetrating them and releasing symbiotic bacteria that kill the pest quickly and effectively. Nemasys C is a safe and natural alternative to chemical pesticides, with no harmful effects on humans, pets, crops, or beneficial insects.

Ideal for use in pine plantations, tree nurseries, greenhouses, and ornamental planting schemes, Nemasys C offers effective curative control when applied in moist conditions and at optimal soil temperatures between 12°C and 30°C.

Available in 50 million and 250 million nematode packs, with larger bulk options also available for professional use.
