Loss of crops in storage after harvesting makes food shortages worse and contributes to rising food prices. These are two of the most critical issues facing the world today.

The World Bank estimates that total annual losses for grain in storage in sub-Saharan Africa amount to $4 billion US dollars - more than the total value of food aid delivered to the region over the last decade.

Insect and mite infestation is a particular challenge. Traditionally, it鈥檚 been treated with chemicals and fumigants. But with the number of insecticides approved for use in the EU and around the world falling, insect species may develop greater resistance, which could make losses even worse.

Hampshire based company, , received a 拢270,000 grant from Innovate UK to develop a safe and effective treatment to protect grain in storage against infestation.

They came up with a wax micro powder called Entostat, which acts as a delivery system for anti-insect fungi found naturally in UK farm grain stores.

Harnessing nature

Entostat uses an innovative micro powder technology that mimics the fine wax particles on the surface of carnivorous plants. The result is a naturally occurring biological pest control agent derived from a fungus found in grain stores.

鈥淭he technology works really well. It鈥檚 simple and it harnesses nature - using fungal spores that have been around for millennia and whose purpose in life is to feed off insects,鈥� said Phil Harris, Exosect鈥檚 Chief Administration Officer.

The technology is a spin-off from a discovery made by a professor of entomology at Southampton University, who found that tiny wax particles on the inside of carnivorous pitcher plants adhere to insects via electrostatic attraction.

While the formulation has been many years in the making, the potential rewards are considerable.

The global market for insecticides used in grain storage alone is estimated to be over 拢90 million per year - and this is only one of many areas where the technology could be used.

鈥淚t has the potential to cover a wide range of staple crops and commodities such as rice, cocoa beans, pulses or animal feed,鈥� said Georgina Donovan, Exosect鈥檚 Communications Manager.

鈥淚nnovate UK funding has been instrumental in developing the biological aspect of our business so we can access this major growth market in the agricultural sector.

鈥淲e can see the beginnings of markets for our technology in other sectors like public health and animal health as well so the timing couldn鈥檛 be better.鈥�

Attracting attention

Exosect has received funding from the Bill & Melinda Gates Foundation to explore ways of helping subsistence farmers to protect grain in sub-Saharan Africa.

The Australian Grains Research and Development Council has also provided funding to research its uses in storage after harvest.

鈥淲e have a formulation with an extremely low environmental impact and high efficiency at a time when regulators are taking other insecticides off the market,鈥� said Martin Brown, CEO of Exosect.

鈥淲e can show partners and investors we鈥檝e done the ground work on commercialisation, including protection for the technology itself.鈥�

The company has also received venture capital funding from three British funds, one Dutch fund and a range of individuals, as well as support from the Department for Environment, Food and Rural Affairs (DEFRA).

However, Phil Harris is keen to stress the importance of Innovate UK support:

鈥淚t gives the technology credibility, which is critical for a relatively small company like us.鈥�

Protecting the future

Exosect鈥檚 CEO Martin Brown emphasised the importance of intellectual property protection when taking the product to market:

鈥淎s a small company we don鈥檛 have the capacity to launch a product in the marketplace on a global scale. We鈥檙e looking to license our technology and are seeking licensing and commercial partners - initially focusing on Europe and the US.

鈥淕etting to this stage is the culmination of nine years鈥� work. If it wasn鈥檛 for the long-term vision of Innovate UK and the other funders we wouldn鈥檛 have got anywhere near as far as we have.鈥�
