This project focuses on harmful bugs (heteropthera) in organic vegetable, fruit and flower cultivation. The research question is: how can growers recognise, monitor and control harmful bugs? Together with a network of organic growers, observations are carried out in tunnels and in the open air. We link this monitoring to existing warning systems. We combine these insights with existing knowledge to develop a bugs guide (distinguishing between harmful and beneficial species), where possible, control guidelines. We deploy T. basalis on farm at a minimum of one organic tunnel grower who has had problems with N. viridula in the past. We will also test any new measures on farm for other bugs. Growers will be actively involved through monitoring on their farms and study day to exchange knowledge and experiences.
