NemaTrident CT is the first product to market for the UK’s Bionema, a spin out business from Swansea which is developing a new range of biopesticides products based on 20 years of scientific research.

It goes on sale in March 2017 for vine weevil control in soft fruit and ornamentals and pine weevil in forestry.

Targeted at vine and pine weevil, the initial part of the trial programme was carried out in the forests of Wales, where the cold tolerant biocontrol agent, effective down to 8ºC, which uses naturally occurring insect parasitic nematodes (Heterorhabditis downesi) as its base.

Later in the year it was tested against vine weevil in soil grown strawberry near farm in Herefordshire, with a kill rate of 100 per cent. This trial was moderated by growers, agronomists, distributors and manufacturers.

NemaTrident CT has a cocktail of ingredients, which, acting together, have radically altered performance,  said Bionema CEO Dr Minshad Ansari.

Vine weevil causes £40m damage to the UK horticulture industry yearly and £5 billion worldwide, and recent ban of the widely used insecticide Chlorpyrifos, also known by the trademark Equity exacerbates the problem. Horticulture Week hosted a Vine Weevil summit in July 2016.

Bionema assessed 17 of the best performing bio-control products in the trials.
