Oregon Seed eUpdate e-newsletter


The focus is on agronomic and pest issues. In contrast to the Oregon Seed MagazineThe goal of this e-newsletter is to provide timely updates to Oregon seed producers and field reps. The focus is on agronomic and pest issues. In contrast to the Oregon Seed Magazine, the e-newsletter has an emphasis on regional reports from field reps, consultants, growers and OSU research and Extension staff. We plan to include label updates, links to pertinent research and publications and a calendar of meetings and tours.

Palisade 2EC SLN Approved for Oats in Oregon

Tanner Sheahan

Below is a copy of the letter sent out by Rose Kachadoorian of ODA announcing the approval of a 24c label for Palisade2EC on oats in Oregon to help prevent lodging. There's a fair amount of oats out there this spring and while this may not be a huge crop for growers in the Willamette Valley I wanted to get the information out to you.


RE : Syngenta Crop Protection, Inc /Palisade 2EC (a.i. Trinexapac-ethyl)
EPA Registration No. 100-1241, EPA SLN No. OR-120009
Site- Oats
The Oregon Department of Agriculture is pleased to enclose SLN OR-120009, a registration
under FIFRA Section 24(c), to allow for the use of Palisade 2EC (Trinexapac-ethyl) on oats in
Oregon to reduce lodging. Concerned Oregon oat growers initiated conversation with Oregon
State University (OSU)- Extension and Syngenta Crop Protection, and are the driving force
behind this SLN.
This SLN will expire December 31, 2013, Syngenta has committed to collecting NW specific
efficacy data. When sufficient data are submitted, the Department will consider extending the
expiration date.
Oats are on the EPA Stamped and Accepted label (2/17/2012); however, they are not on the
market label. Oats are not on the market label because Syngenta is still in the process of
developing efficacy (including optimum timing) data.
Growers in Oregon planted late because of excessive rains, and alternate crop uncertainties.
Because of the amount of rainfall in Oregon, crops are especially susceptible to lodging (water
helps weigh down plants). In addition, some believe that using Palisade 2EC on oats will help
reduce the straw load on the fields, which will possibly help facilitate no-till planting.
According to Dr. Mike Flowers OSU Assistant Professor (Extension Cereals Specialist), oats
grown in the Willamette valley region of western Oregon are typically a forage type grown
under contract as a seed crop. Thus, oat growers are trying to maximize seed yield in varieties
that are tall, weak stemmed and prone to lodging. This leads to significant agronomic
challenges for growers as they try to optimize inputs while preventing lodging. It is in this
capacity that Palisade would be very useful to Oregon's oat growers.
If you have any questions, please do not hesitate to contact me. Thank you.
Sincerely,

Feel free to contact your CPS Fieldman if you have any questions about using Palisade2EC on your oat crop and we will have copies of the SLN here at the Tangent branch with the product.

Leaf Roller in New FIlberts

Here are some pictures of potential damage from leaf rollers in new planted filberts.

Leaf feeding.

New growth curling due to damage to the stem.

Newest bud severed by feeding on the stem just below it.

Leaf rolling and new growth damaged.

Leaf damage and new growth damaged.

You can see the leaf roller worm right about in the center of that last picture. (You'll also notice what I believe to be a sweat bee, no concern to the filberts.) The worst damage the leaf rollers do is sever the new growth as you can see in a couple of these pictures.

If you notice any damage at all in your new filbert planting please talk with your CPS fieldman.
