OSU’s extension team in seed crops has issued an alert regarding an emerging pest in Willamette Valley grass seed crops. A new publication addresses true armyworms and potential control measures.

Camelina: Adaptation and performance of genotypes
Here’s a new article on the adaptation and performance of camelina that will be published soon in Field Crops Research. Camelina is a Brassica family oil seed crop that has demonstrated potential for production in the Pacific Northwest and is thought to have a place as a rotation crop for small-grain cereals and grass seed crops. This work was led by Stephen Guy at Washington State University, a member of our research team.
Several key findings from the work include:
- Planting camelina in the spring produced higher seed yields than planting in the fall.
- Seed yields ranged up to 2948 lbs/acre across the four study sites.
- With increasing seed yield, oil content of the seed was reduced.

Yield mapping in perennial ryegrass seed crops
Crop fields are generally not uniform and the harvested yield can vary across the field. Perennial ryegrass seed production fields are also not very uniform but some farmers use yield monitors on their combines to estimate seed yield and the spatial variability in seed yield across their fields.
This variability can be mapped for the fields where yield monitors are used and these maps can serve as the basis for making crop management decisions. But the reliability of these yield monitor-based estimates was not known for perennial ryegrass seed crops.
A recent paper by co-authored by extension agronomist in seed production Bill Young and others at OSU finds that there is considerable variability in seed yield in an otherwise uniform perennial ryegrass seed field and that a yield monitor can reliably capture this variability in seed yield.

PGR approved for use in red clover and crimson clover seed crops in Oregon
A special local needs label has been recently approved for use of Palisade EC plant growth regulator for red clover and crimson clover seed crops in Oregon. This is timely because the window for application of the product on these crops is near.
For more information, here is a copy of the SLN label:
Palisade EC for Red Clover and Crimson Clover Grown for Seed
As always, follow the label when applying this or any other product. Mention of this product does not constitute an endorsement by Oregon State University.
Welcome to Seed Production
The site is under construction right now but should be fully operational in the near future. Thank you for your patience.
