What’s Hoppening with the Hoppers?
As we all know, it has been an impressively rainy season so far here in the Northeast. While the rain has fueled pests like downy mildew and aphids in our hopyard, potato leafhoppers (PLH) have thus far posed less of a threat to the production of our hops. However, even with lower numbers, these pests …

Excited for the 2017 growing season? We are…and so are the bugs!

Our …
Minor Pests = Minor Problems!
The three major pests of Northeastern hopyards—potato leafhoppers, two-spotted spider mites and hop aphids—can cause significant economic losses. For that reason, we keep a close eye on their populations in our research yard by scouting weekly. From time to time, other pests pop up in our hopyard, but because they don’t seem to affect yields, …

3 Things that Matter in Pest Scouting: Location, Location, Location
“There are three things that matter in property: location, location, location.” We have found that location also matters in growing hops, particularly this spring. Southern Vermont has been exceptionally dry for long periods, while northern parts of our region have been soggy, to say the least. The cool, wet conditions that we’ve been experiencing in …

Potato Leafhoppers Have Arrived
Adult female potato leafhoppers (Empoasca fabae) arrived to the Borderview research farm in Alburgh between May 23 and May 26. To identify them, stick your hand in a hop plant and ruffle it around–you may see light colored potato leafhoppers fly out. Whether you have seen potato leafhopper yet or not, it is time to …
June 2013 Hops Scouting Report
As you scout for insects and disease in your hopyards this spring, undoubtedly dodging puddles, you are likely finding fewer critters than usual. The cool, wet weather that we have been experiencing lately has taken its toll on the insects that are typical for this time of year. However, downy mildew is one problem …
