NemaTrident B contains a naturally occurring beneficial entomopathogenic nematode, Heterorhabditis bacteriophora formulated in a wettable powder, enclosed in a non-water-soluble pack. NemaTrident B is safe and sustainable, providing highly effective control of larvae when they come into direct contact with the target pest. Small larvae (early stages) are most susceptible. To enhance the movement of NemaTrident B and the targeting of larvae at application, it is recommended to always use it in conjunction with NemaSpreader. The unique dual component system ensures maximum dispersal of infective juvenile nematodes within the soil which then go in search of larvae to penetrate and kill.

Pack sizes: 250 million and 500 million
Nematode species: Heterorhabditis bacteriophora
Target pest: Welsh chafer, cockchafer, Garden chafer, Summer chafer
Minimum soil temperature: 12°C for 3 – 6 hours per day

Chafer grubs are the soil borne larval stages of chafer beetles. Adult chafer beetles emerge from May onwards, depending on the species, season and weather patterns. Egg laying begins 2-3 weeks after emergence, and larvae hatch 3-4 weeks later.

NemaTrident B should be applied from July to September to target emerged larvae. Best results will be achieved when applied during periods of prolonged soil moisture and when applied to smaller larvae. Note that some chafer species have life cycles that last up to 3 years, with mixed populations of large and small larvae present at any one time. Where high numbers of larvae are present applications over several seasons could be required to manage populations.

Apply 5 billion nematodes per ha.

NemaTrident B pack size	Area treated per application, to deliver 2.5 billion nematodes per hectare	Number of packs to treat 1 hectare
250 million (0.25 billion)	1000 m2	20
500 million (0.5 billion)	2000 m2	10

Soil temperatures need to be 12˚C or above for 3-6 hours per day for the nematodes in NemaTrident B to be active. Soil moisture is also required for the nematodes to move freely and for larvae to be active close to the surface. NemaSpreader is an essential partner to maintain optimum soil conditions for NemaTrident B activity.

Take NemaTrident B out of the storage fridge 20 minutes before starting the mixing procedure

Dissolve product in 10-20 litres of water

Use complete pack as distribution of nematodes is not homogenous. Rinse the empty pack in the mix

Stir for 5-10 minutes until completely dissolved

Fill the spray tank with 3/4 of the required water volume. Add the NemaSpreader at the rate of 5 litres per hectare

Then add the NemaTrident B solution and top-up with remaining water volume. Maintain constant gentle tank agitation

Spray immediately. Do not store for longer than 4 hours in the spray tank

Getting the best results

NemaTrident B should be applied to moist soil
Apply in 500-1000 litres of water per hectare
Clean spray equipment and spray tank before use
Remove all in line filters, nozzle filters and sieves which could block nematodes
Use nozzles with at least 0.8mm diameter
Apply early morning or in the evening when light levels are low
For turf use apply with 5 litres of NemaSpreader per hectare
Irrigate NemaTrident B in immediately after application but do not saturate the soil (use 1-2 litres of water per sq m)
Soil should be kept moist for 14 days after application

Soil temperatures should be 12˚C or above for 3-6 hours per day.

Syngenta XC 08 nozzles can be used to apply NemaTrident F. For other nozzles check the orifice is greater than 0.8mm diameter

Compatibility

Do not apply in tank-mix with fertilisers. Application of fertilisers prior to or after NemaTrident B is safe. NemaTrident B is compatible with most pesticides and biostimulants, however a few do have a negative impact; check the Syngenta website or with your local advisor for detailed information.

When products are not compatible, or you are unsure, apply the product 3 days before or 14 days after application of NemaTrident B.
