Hop Pest: Eastern Comma Butterfly

Posted by NeHA on Aug 7, 2011

 UVM Extension Agriculture: Northwest Crops and Soils Program

While spikey and rather exciting looking with a remarkable set of eyebrows, the Eastern comma (Polygonia comma) is generally perceived as a pest with no economic importance.  However, this might be because the Pacific Northwest, where most of the hops industry takes root, is outside of the Eastern comma’s habitat range.

The Two Spotted Spider Mite in the Northeast Hopyard

Posted by NeHA on Aug 6, 2011

 By Steve Miller, Cornell Hops Specialist 


The two spotted spider mite (TSSM) (Tetranychus urticae Koch) is a common pest of many crops and ornamentals. Hop growers, landscapers, arborists, and vegetable and fruit growers are familiar with these small 8 -legged creatures that are more closely related to spiders than insects. They can be a major cause of crop reduction in hops, both by reducing productivity of the leaves and direct damage to the hop cones. The TSSM is found worldwide and the Northeast US is no exception.

Managing Powdery Mildew of Hops in the Northeast

Powdery mildew (Podosphaera macularis (Wallr.) U. Braun & S. Takam ) is one of the predominant fungal diseases that you might encounter in your hopyard. Any pest issue in your crop can be daunting but a diligent integrated pest management (IPM) approach can help overcome many issues. The goal of integrated pest management is to integrate a multipronged approach including prevention, observation, and various intervention strategies to reduce or eliminate the use of pesticides while at the same time managing pest populations at an acceptable level. This article will provide you with some guidelines on how to manage powdery mildew in your hopyard.

Recently, injury and even death of hop plants from potato leafhopper feeding has been observed in Vermont. Leafhoppers are damaging insects that have an appetite for more than 200 crops. The potato leafhopper (Empoasca fabae) is considered an economic pest of other common northeast crops such as alfalfa, clover, potato, beans, raspberries, and even young maple trees. Interestingly, grasses are not considered a host. This article will help you identify leafhopper infestation as well as provide direction on how to control this damaging pest.

Spider Mite Destroyers and Spined Soldier Bugs!

Posted by NeHA on Aug 5, 2011

There are numerous insects in every hopyard, some of which are pests, some of which can be very beneficial.  Knowing the difference can reduce pesticide applications.   Spider mite destroyers and spined soldier bugs are two of the “good guys.”  Learn more about these beneficial insects.

Hops and Beginning Brewing Resource

We just found a new information source that we think will be helpful to NeHA growers and those considering opening farm breweries.  Check out Beer Legends.  We’ve also linked to the Hops Variety page on our Info and Links post under Resources.

2011 National Hop Report

Posted by NeHA on Jan 4, 2012 

Message from Steve Miller, NYS Hop Specialist:
USDA just released the 2011 National Hop Survey.  As you will see, it includes the three major production areas of Washington, Oregon, and Idaho.  We must take this information with a grain of salt. While I attended the Hops Research Meetings in Yakima earlier this year the industry leaders spoke about how much it costs their organization to have the survey done and whether the reported information is accurate because not all growers respond, and many who do may not be giving complete information about prices, yields, and varieties.  All in all, I do think this is very useful information for our growing hop industry as we can see changes over time and what our competitors are doing.  Enjoy the read:  National Hop Report-NASS 12-11[1]

Info and Links

Posted by NeHA on Aug 6, 2011

We cannot begin to count the number of inquiries that NeHA members get from people interested in growing hops in the Northeast, Southeast and MidWest.  We have found that the questions are often the same.  So, we have developed a list of links and other helpful information.  Perhaps this page will answer your questions.  Become a NeHA member to get access to our online community and forum for more information and networking opportunities.
