Bee vectoring of biologicals in sunflowers as a crop protection tool

Abstract

An inoculum dispenser system developed by Bee Vectoring Technology Inc. (BVT) fits inside commercial bumble bee hives and another system attaches to honey bee hives. Each system is one-way so that bees acquire inoculum powder when exiting the hive but not when returning to the hive. BVT’s dispensers are filled with VectoriteTM, which is a specially formulated and patented powder prepared from all natural materials mixed with one or more beneficial microorganisms. BVT’s own proprietary fungus, Clonostachys rosea strain CR-7, which is effective in controlling a number of devastating diseases such as Sclerotinia Head Rot (SHR). VectoriteTM adheres to bees, aiding in the transport of added active ingredients to flowers in the crop. Bumble bees can be universally used in greenhouse operations, and some countries approve their use in open field crops, whereas honey bees are exclusively used in open field conditions. The effectiveness of the BVT plant protection biocontrols combined with the pollination effi ciency of both insects, make the BVT system a solution that harnesses the power of nature’s best workers and microbials.
