Glyndwr University works on 'eco-friendly' pesticides

Scientists at Glyndŵr University in Wrexham are trying to create an eco-friendly spray which stops insects destroying crops by interfering with their pheromones.

They hope to control pests by releasing synthetic pheromones - chemical messengers carrying information between individuals of the same species.

It is hoped the spray would disrupt mating and egg-laying.

It would target specific species without harming others, it is hoped.

Scientists at the university's Centre for Water Soluble Polymers are working with Deeside-based Russell Integrated Pest Management (IPM) to develop the spray.

It will be designed to target specific pests identified by growers and farmers without destroying any other life forms, the university says.

It is hoped the spray will be cheaper than traditional pesticides.

Glyndŵr University said its expertise in using biopolymers as thickening agents to affect the consistency of materials, will be crucial to the project.

A spokesperson said: "In order to successfully disrupt the insects, the pheromone release needs to have a concentration for a sufficient length of time.

"If it's too thick the liquid won't spray and if it's too thin the spray will just wash away when it makes contact with any crops.

"Consistency of the spray is crucial therefore.

"The development of a new pest control product is a challenge that we are very much looking forward to tackling, as it will prove beneficial for local industry."
