After the cultivars present in each bed at the newly-dedicated Wisconsin Cranberry Research Station were fingerprinted and named, Dr. Zalapa’s lab was able to compare historic yields with the purity of the vines in each bed. They were also able to compare the visual assessment (height, color, and yielding/barren) of cultivar contamination, with the measured genetic contamination. Read more here.

Following spring hailstorms, many growers throughout Wisconsin are observing vegetative side-shoots on uprights. In many cases the uprights that exhibit later shoots also have an apical bud that is very delayed in development, and it is not clear whether that apical bud will pull through and bloom. Scouting beds will be critical to estimate the percentage of uprights with apical buds either damaged or not developing Read more here.

In the last couple of weeks, we have detected, at several marshes, the presence of very small leafhopper nymphs that are most likely blunt nosed leafhoppers (BNLH). While the presence of BNLH is still sporadic in WI, with the vast majority of marshes not having BNLH present, it is strongly recommended to monitor by sweeping beds from mid-May to mid-June to ensure that BNLH is not establishing on your marsh.
