Loopers are latent and storms are splendid!

Windy gusts of up to 30 MPH and nearly 1″ inch of rain this week. Yes, believe it or not, it’s bug season!

Diamondback moth (Plutella xylostella) is the most serious insect pest of Brassica crops (including cabbage, broccoli, etc), both in the US and worldwide. Economic impact estimates exceed $4 billion annually.

One of the reasons DBM is so hard to manage is because it quickly develops resistance to insecticides. In fact, (IR) has been noted in over 600 cases, for nearly 100 unique active ingredients such as carbamates, pyrethroids, and spinosyns. The most recent concern of IR is within the diamide insecticides. Diamide products that Willamette-Valley brassica producers rely on include chlorantraniliprole, cyantraniliprole, and flubendiamide. Trade names are Coragen, Exirel, and Synapse. We are currently conducting research to test for IR in regional populations of DBM and related pests.

Scientists at Cornell University have developed an “insecticide-free management approach” that involves releasing genetically-modified DBM moths into the landscape to cause eventual mortality of females. This research, while novel, is also controversial. Cornell has applied for a permit to make field releases of their transgenic moths in NY state. An environmental assessment has been conducted by USDA-APHIS, and public comment is welcome until MAY 19th, 2017.

Over 500 people currently subscribe to VegNet, a 28% increase from just 3 years ago. During the transition from the old format (static webpage) to this new (blog), we’ve migrated the list of all subscribers. I put together a graphic to get an idea of what type of people utilize the service.

A few key points:

  • The VegNet program is doing what it’s supposed to;

serving as a frontline IPM resource for the agricultural community.

  • Everyone is welcome! Whether you are a student, home gardener, ag producer, policy maker, or armchair biologist – please feel free to join us! Subscribe to the weekly newsletter (box at left) and review this post of how to interpret data tables.
  • A note to current subscribers:  If you would like to identify with one of the industry categories above, drop me a line and I’ll update your info. And most importantly: THANK YOU ALL for utilizing and supporting this program!

Stay tuned! The first report of the season will be published on or before April 14th.

In the meantime, good luck with spring plantings!

Update: Thanks to geolocation technology, I can now access broad, general data about where VegNet reports are being read. Don’t worry – this does not go deeper than state level, and the location is not associated with your email address. That is, I’m not ‘spying’, just excited to see so many VegNet followers “East of the Mississippi”!

This made me wonder if some of these supporters are researchers at peer land-grant institutions. Which, of course, led to an excuse to make another cool graphic ☺
