Bee Vectoring Technologies announced successful results from trials in sunflowers conducted during 2017. The trials were designed to evaluate the ability of the BVT system consisting of a bee hive with dispenser technology through which BVT's proprietary plant beneficial microbe is delivered to crops, to manage sclerotinia head rot, an invasive fungal disease that causes high levels of loss in sunflowers and currently has no viable method of prevention. This was the second year of trials in sunflowers in collaboration with North Dakota State University, and the first year in which both BVT's current bumble bee hive dispenser and the new honeybee hive dispenser were tested. In replicated trials conducted at North Dakota State University (NDSU) using bumblebees, the BVT system delivered a 47% reduction in incidence and a 20% reduction in the severity of sclerotinia head rot on average across three different observations. Similar level of reductions in disease were seen in the trials conducted in 2016. Yield differences could not be quantified this year due to collection issues during the harvest.
