The Japanese beetle (Popillia Japonica) can be a significant economic pest in Northeastern hop yards. Japanese beetles begin to show up in Vermont at the very end of June or early July, and are most active on warm, sunny days. We spotted a Japanese beetle in our hop yard at Borderview Farm on July 1.

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, […]
Biological pesticides, or biopesticides, are pest management tools derived from animals, plants, bacteria, and/or naturally occurring minerals. Many common biopesticides uses microorganisms like entomopathogenic bacteria, fungi, nematodes or viruses as their active ingredients. The most widely used microbial pesticides are derived from Bacillus thuringiensis, or Bt. Each strain of this soil bacterium produces a different […]

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 […]
Japanese beetles can be a significant economic pest in hops, so proper identification and management decision-making are important if you are going to avoid losses. Check out our article Japanese Beetles in Hops in the Northeast for more information on Japanese beetles and some control options.
