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®.

How to get the best from Nemasys F^®:

• Apply when the substrate is between 10-30 oC
• Use immediately on receipt of packs or refrigerate at 5oC (do not freeze)
• Use within expiry date
• Use the entire pack and do not store stock solution or diluted product
• Make a stock solution as directed on the label, making a paste in the first instance and then adding remainder of the water, to avoid lumps forming; this solution should be mixed thoroughly to ensure nematodes are well dispersed and kept agitated
• Application is as a foliar spray or drench to the growing medium via boom, lance or sprinklers, selecting the nozzle to give a medium (foliar) or coarse (drench) spray; the nozzle aperture should be greater than 0.5 mm, or via drip irrigation. A Dosatron unit can be used.
• Remove all fine filters (50 mesh or smaller) from the application equipment
• Partially fill tank with water, add stock solution, fill with water to the required level and maintain agitation
• Do not exceed 300 psi/20 bar/2000 kPa pump pressure
