Between the Vines

Special Guest Dr. T Bates discusses crop estimation results and the factors that influence a decision to thin a crop. Factors include the bloom date, precipitation, growing degree days and the market.  Some factors are more important than others but in vineyards that did not suffer hail or freeze damage, over-cropping is a concern in 2021.

The team discusses calendar and degree-day timing. In the Lake Erie region, it is time to scout and spray for Grape Berry Moth.  Crop Estimation timing is just one week away. Local weather stations tracking growing degree days for GBM control vary by 10 days.

It is the season for scouting secondary pests. If you’ve never had an established population of a secondary pest, tune in for a reminder of scouting protocols and economic thresholds. Some of these when populations get established can significantly impact yield, despite their secondary status. Scouting and even pesticide applications can be essential.

We all love warm weather and sunshine but how do we manage vineyards in this unusual weather pattern? Warm weather and sunshine have all but eliminated infection periods in the Lake Erie Region over the past 10 days.  With low disease pressure, how flexible can spray schedules get?  How do crop load and frost damage change that calculus? The team tackles this risk management conundrum.
