First international postharvest Loss Congress in Rome:

Italy: Re-formulation of insecticide presented at congress

As next generation pesticide technology seeks to deliver ‘more with less’, there is a delicate balance to be achieved between reduced chemical inputs and the maintenance of efficacy. In the latest development of its Entostat technology, Exosect is able to demonstrate a novel solution to this challenge.

The widely used active ingredients deltamethrin, a synthetic pyrethroid and pirimiphos methyl, an organophosphate, have been re-formulated to optimise dispersal and increase pick up by target pests. The Entostat patented micro-powders harness the use of natural properties such as electrostatics and can be used to improve the delivery of both chemical and biological ingredients.

This approach enables equivalent insect mortality with significantly lower use of active ingredients, both in application rate and chemical loading. The amount of deltamethrin required is half that compared with the conventional deltamethrin product, whilst pirimiphos methyl is added at less than 15% of the pirimiphos methyl benchmark product. Due to increased evenness in distribution and improved transfer to target insects, the quantity of formulation required for dosing has also been significantly reduced to a fractional 1g of product per 20kgs of grain.

The results of this research will be presented by Research Scientist, Freya Scoates of Exosect next week at the International Congress on Postharvest Loss Prevention (4-7th October 2015), organised by the Archer Daniel Midland institute in Rome, Italy.
