2017 Dickeya and Pectobacterium Summit

November 9, 2017

University of Maine staff are working to address Dickeya, a recent and potentially “devastating bacterial disease in Maine seed potatoes.” Projects are being conducted in Maine and in collaboration with colleagues in other states. We have been successful in pursuing funding opportunities and hope to have news soon on additional pending grants.

Some of the efforts include:

  • Chemical control of Enterobacteria
    • Identifying seed lots with Enterobacteria
    • Enterobacteria spread and epidemiological studies
    • Enterobacteria identification
    • Enterobacteria pathogenicity
    • Enterobacteria levels in a seed lots related to stand loss
    • Movement of Enterobacteria in a seed system
    • Postharvest test for the presence of • Enterobacteria

Results from these studies will be presented at the 2017 Dickeya and Pectobacterium Summit November 9, 2017. The summit will be your chance to hear about improvements in the dormant tuber post-harvest test, among other topics.

For interest, please see a bulletin #482 entitled: “Factors Affecting Potato Blackleg and Seed Piece Decay.”

The Introduction has this sentence:

“State potato seed certification officials discriminate against the presence of blackleg and many buyers refuse to purchase seed stocks known to have even a small percentage of the disease.”

By the way, the bulletin was from 67 years ago, May 1950.

Guess the Pest! #7

Bill Cissel, Extension Agent – Integrated Pest Management;

Congratulations to Jeff Peat for identifying the grass sawfly in this past week’s Guess the Pest and for being selected to be entered into the end of season raffle for $100 not once but five times. Everyone else who guessed correctly will also have their name entered into the raffle. Jeff will also receive a FREE copy of A Farmer’s Guide to Corn Diseases. Click on the Guess the Pest logo below to participate in this week’s Guess the Pest! For Guess the Pest # 7, we will also be giving away A Farmer’s Guide To Corn Diseases ($29.95 value) to one lucky participant.


The correct answer to this past week’s Guess the Pest is Grass Sawfly. Grass sawflies damage small grains by clipping grain heads. They are often confused with true armyworms which also clip small grain heads. There are several reasons why it is important to be able to distinguish between grass sawflies and true armyworms:

1) Grass sawflies are more damaging than true armyworms because they prefer to feed on small grain stems as opposed to true armyworms that will typically feed on leaves before clipping heads. Also, grass sawfly damage usually occurs before the peak of armyworm damage.

2) The threshold for grass sawflies (wheat and barley – 0.4 linear ft of row) is lower than the threshold for true armyworms (barley – 1 per linear ft of row/ wheat-1- 2 –per linear ft of row).

3) Not all products that are labeled for true armyworm control will provide control of grass sawflies.

4) Insecticide rates also differ between the two species for some products.

There are several features that can be used to distinguish grass sawflies from true armyworm.

Grass sawflies larvae are active during the day and can often be found on the plants so “shaking” plants to dislodge larvae is necessary when sampling. They can be identified by their green color, large amber head, and 5-7 pairs of fleshy prolegs. Counting the number of prolegs is the most reliable way to determine if the “worm” is a grass sawfly or true armyworm.

Grass Sawfly Larva

True armyworms are active at night and can often be found curled around the base of plants or under crop residue during the day. Larvae have 4 pairs of fleshy abdominal prolegs not including the pair of legs at the very end of the abdomen. There also appears to be a large gap between the 3 pairs of true legs and the start of the fleshy prolegs.

True Armyworm Larva

If your field is at threshold for grass sawflies, here are several things to keep in when selecting which product to apply. Is the insecticide labeled for grass sawfly control? What is the days to harvest restriction (this varies among products)? Is the insecticide labeled on the crop (not all products are labeled for all small grains)?

Here is a link to our Extension Fact Sheet for additional information on identification, biology, and management of grass sawflies and true armyworms in small grains:

Be Sure to Scout Early-Planted Corn

Most of our soil-applied herbicides provide about 4 to 5 weeks of control, depending on rate, soil types and soil moisture. Some of the first planted corn has been in the ground at least five weeks, so be sure to get back to those fields to see if a postemergence herbicide is needed. With the warm weather we are experiencing, species like Palmer amaranth, common ragweed, and common lambsquarters, will be growing fast and will quickly get to sizes that may limit herbicide effectiveness.

New Field Crop Weed Management Guide

Mark VanGessel, Extension Weed Specialist;

There is a new “Mid-Atlantic Field Crop Weed Management Guide” developed by weed specialists from Penn State, University of Delaware, University of Maryland, Virginia Tech, and West Virginia University. The 240-page guide covers corn, sorghum, soybean, small grains, and hay and pastures. The guides includes information on commonly used herbicides for these crops, including relative effectiveness for burndown, preemergence, and postemergence control of most of the common weeds in the region. In addition, there are tables for herbicide premixes and what is included in the premixes, and a section on management of problem weeds. The guide is available in the Delaware county Extension offices for $15 or can be ordered on-line at Available on-line are the printed copies for $25 for a printed copy; an enhanced pdf copy for use on computers and tablets for $15; or both a hard copy and pdf for $35. A free low resolution pdf is available at Note the low resolution version is not “searchable”.

Final Considerations in Small Grains

Nathan Kleczewski, Extension Specialist – Plant Pathology;; @Delmarplantdoc

Our barley is starting to ripen and wheat finished flowering last week in Delaware and Maryland. Growers will want to check fields 18-24 days after flowering to assess fields that may have elevated risk levels for vomitoxin contamination. Fields with a high incidence of Fusarium Head Blight may be at risk for elevated vomitoxin. To assess Fusarium head blight (FHB), run multiple transects through a particular field. The number of transects should be sufficient to give you a fairly good overall representation of the field. When we run field level assessments for FHB a transect typically is 75-100 yards long. Fifty heads are picked during the course of walking the transect, with care taken to not look at the heads being sampled. This way you ensure that your sample is not biased, purposely or not, in favor of healthy or symptomatic heads. After you have collected all the heads from a transect, mark the total collected and the number with FHB symptoms (bleached florets or heads with pink at the base of the floret in many cases). If you have a high incidence of FHB you should try and do the following for that field:

  1. Harvest it as early as possible
  2. Dry grain to at least 15% moisture if you have the ability to do so
  3. Store the grain separate from fields without significant FHB issues
  4. Harvest with an increased fan speed, which helps removes lightweight, vomitoxin-rich tombstones from the heavier weight, higher quality grain.
