Delivery of different formulations of beneficial microorganisms can be accomplished using conventional sprayers or with bees. Honey bees have been used to disseminate beneficial fungi, bacteria and viruses to apple, pear, strawberry and clover for control of diseases and insects. Over the last few years, we have used bumble bees and honey bees to deliver a powdered formulation of Trichoderma harzianum to strawberry flowers and results on Botrytis control and yield enhancement have been encouraging.
