Hop Pest – Eastern Comma

While out in the hopyard this week, we stumbled upon this little guy and his friends on the underside of some leaves, chowing down on a fine looking row of Cascade.

Eastern comma munching in the hopyard.

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 ones in our yard seem to munch at quite a clip, it is easy to imagine them multiplying and making a serious dent.  Their populations are knocked back by the pesticides we use for spider mites and leaf hoppers, but we have been practicing the ol’ fail-safe organic pest-control method: whenever we see ’em, we squish ’em.

The eggs are green with ridges and can often be found stacked one on top of another.

The body color of the larvae is highly variable, a quick Google Image search will reveal a lot of diversity.

Polygonia comma

The adult butterfly is orange and black, but varies in color depending on the time of the year.  It can be identified by the silvery comma on the middle of the hind wing.

Note silvery comma

In the past, this pest has been dubbed the “Hop Merchant“.  Growers in the early 1900s would base their projections for the year’s prices on the degree of the chrysalis’s golden luster.

University of Florida Extension has a great fact sheet about the Eastern comma, and we encourage you to look through it.

Hop Fertility Management in the Northeast

The increasing acreage of hops in the Northeast has prompted the need for fertility guidelines for this new and emerging crop. Unfortunately there has been no regional data generated to determine hop nutrient requirements for our soils and climate. Some basic fertility guidelines can be developed from research and information available from the Pacific Northwest (PNW). It is important to remember that these are just guidelines developed to help assist producers with maximizing hop yields until more local data can be generated for this crop. Read more…

Hops Recordkeeping Booklet

Greetings all,

The hops Extension teams in VT and NY have put together a “Hops Recordkeeping Booklet”. This booklet will give you a spot to write down pertinent hop information, including pests, fertilizers, irrigation, etc. It pays to keep good records and it will help you tract beneficial practices over time. We are also hoping we can all learn more about growing hops if we document what is going on in New England hopyards. If you want a booklet email us and we can send you a few in the mail.  Don’t forget to send your address so we know where to mail them.

Rhizome time!

We have received a lot of calls lately on when to plant hops and how to store them until they are ready for their permanent home.  Most of you who have ordered rhizomes to be planted this year will have already received them.  When you plant them depends a lot on how cold and wet your soil is.  In Vermont you can still go snowshoeing in places, while other folks are already out in the fields.  If there’s still frost in the ground, needless to say, it’s probably best to hold off for a bit.  If you can’t plant your rhizomes right away, you have a few options.  If you have the space, you can pot them and put them in a greenhouse or under a plastic tunnel.  This way, when you put them in the ground, the hops will already have a head start on the growing season.  This is definitely your best option.  When transplanting, be careful to not break off the growing tip, as it will set the hops back.  If you don’t have the space or resources to pot your rhizomes, you can keep them in a plastic bag in a cool environment.  They should be kept moist, but not wet.  To regulate the humidity, you can surround them with damp shredded paper towel, and spritz them every once in a while.

Your rhizomes or potted hops should be planted once the soil is warm and has dried out a bit.  If you know your soils are heavy and the soil is soggy, the rhizomes won’t be able to breathe and will drown.  Wait until the soil can be easily worked.  Now is the time to get a head start on making a weed-free bed and to add a healthy dose of compost to the planting site. Approximately a spade shovelful per hill is ideal, which comes to about two tons of compost per acre.  Rhizomes should be planted two to four per hill and covered with 0.25 – 1” of soil, with a bud pointing upward.  Water in short increments frequently.  A late hard frost can nip the growing points, which will set the plants back a bit, but shouldn’t kill them.  We heard a few reports of this last year with that late snow fall in mid-May, but folks still had a decent harvest.

Ordering supplies for next year’s hopyard

Greetings folks!

The Northeast Hops Alliance is organizing a cooperative purchase for supplies for next year’s hopyard. Of particular note is the coir twine pricing. If they can get enough orders to purchase 75 bales of coir, at 3400 strings each, then it will only be $300/bale. They might not be able to organize cooperative purchases every year, so plan ahead! You can find the details at the Northeast Hop Alliance website. Scroll to the bottom of the page and download the Cooperative Purchasing Supply Interest Survey.  Please don’t wait, it can take a couple of months for the bales to get here from Sri Lanka by freighter, and we want to get the order in soon!
