Biological efficacy evaluation of CR-7 in blueberries
In early 2022, a leading Georgia grower partnered with BVT to have an independent research company measure and collect data on CR-7’s effectiveness for increasing yield, controlling disease and improving berry quality on his blueberry fields.
- Data was collected on both conventional and organic sites.
- BVT was added on top of the grower standard spray program.
- Trial includes Optimus variety on the conventional site and KeeCrisp variety on the organic site

Less disease & higher profits using bees

It’s been used by growers across the United States since 2019.
Bee vectoring delivers continuous protection directly to flowers. BVT’s VectorHive™ system uses commercial bees to deliver Vectorite™ with CR-7, a biological fungicide for the control of common fungal diseases including Colletotrichum (anthracnose), Botrytis (gray mold) and Monilinia (mummy berry).
