Conquer, which is made from the natural plant material Allium sativum, is injected into the tree where it works its way into the vascular system and fights the blight.
Managing director Jonathan Cocking of arboricultural consultancy JCA has teamed up with Dutch firm Allicin Tree Care and hopes to license Conquer.
Cambridge University Clare College head gardener Steve Elstub said: "I have JCA trialling a new product that has been a success in The Netherlands. It also seems to help with the leaf miner problem."
Cocking said: "One landowner who had quite a number of trees done noticed a major difference but it's early days. We had 20-plus trials from York to Devon last year. We start more trials from the end of March and will assess the success of last year in the summer."
