Why Nemasys F?

Nemasys F® is a biological control product containing nematodes. It effectively targets:

The larval stages of sciarid flies (Bradysia spp.);

- Feeding damage to young roots and the base of cuttings

Western flower thrips (Frankliniella occidentalis):

- Silvery patches on leaves and flowers

- Distortion of foliage and fruit

- Reduced fruit set

- Viral transmission eg necrotic spot virus (INSV) and tomato spotted wilt virus (TSWV)

Leafminers including Tuta absoluta

- Larval mining of leaves, shoots and fruit which is unsightly and can reduce quality and result in downgrading of produce eg tomatoes

Nemasys F® is compatible with IPM (Integrated Pest Management) systems and organic farming. Nemasys F® persists for approximately 4 weeks in moist compost, thus protecting against newly emerging pests. There is no known resistance of the target pests to Nemasys F®.
