The 2021 growing season was much
less challenging than what growers
experienced in 2020.
Seed acreage
was up almost 10% from last year,
and rain events were more plentiful
and much more normal than the
prolonged dry periods the past several
years. This led to significantly higher
yields for growers in most cases.
Overall, the 2021 crop appears to be
healthy with low to moderate disease
levels. As of Sept. 9, the certification
program has 10,168 acres field certified
from 90 farms.
The top acreage varieties certified
for 2021 are:
Inspectors are now performing PCN
soil sampling and are in preparation
for laboratory PVY post-harvest
testing. All samples will be ELISA
post-harvest tested at the certification
laboratory in Presque Isle.
