  1. Targeted precision biocontrol and pollination enhancement in organic cropping systems Biocontrol + Pollination

  2. Main outcomes • Pan-European field trials have consistently shown, using strawberry as a case study, that bee-disseminated biocontrol of the grey mould provides equal or better crop protection than chemical fungicides. • In organic strawberry, marketable yields significantly increase, often by over 50 %. • Improved pollination accounts for about half of the yield increases. • Honey bees, bumble bees, and solitary bees can all be used for vectoring beneficial biocontrol microbes • Efficacy and impact of the entomovectoring technique can be improved by management of hives (size, location, and properties), vegetation management, and optimization of dispensers and properties of the microbial preparate • No negative outcomes on products (berries, bee-products) have been detected, nor on humans or non-target organisms; • The concept has proven to be effective on a wide range of crops, such as strawberries, raspberries, pears, apples, blueberries, cherries, and even grapewine

  3. Impact of bee-pollination and bee-vectored biocontrol of grey mould on the marketable strawberry yield on an organic farmHevonniemi organic farm, Vehmersalmihttp://www.hevonniemi.fi 205% 158% Healthy Mouldy 100% No mould control, No mould control Mould biocontrolno pollination bee pollination bee pollination

  4. New importantresearchquestions • Assuring the availability of healthy bees for entomovectoring, in particular honey bees free of varroa. • Investigating the behavior and visitation of bees in specific wind-pollinated crops, and possibilities to steer bee foraging activity in these crops. • Possibilities to improve bee activity and health via vegetation management (e.g., provision of flowering plants at strategically important locations and times during the year)
