Hyslop Plot Tour

Tanner Sheahan
CPS Tangent

A couple weeks ago we had a snowy rainy tour of some of own research plots. This week we had the great opportunity to view similar research plots at Hyslop farm and also to share our plots with OSU researchers and extension specialists Carol Mallory-Smith, Andy Hulting, and Dan Curtis. It didn't rain on us the whole time...


We looked at several plots with Alion, Matrix, and another potential new product in carbon planted perennial. Many of these new products have very long soil residual so the focus of these trials is not merely crop safety in the carbon planting but also carry-over this fall and next spring. These plots will be drilled to various crops this spring as well as this coming fall to test for chemical damage and residual activity from these products applied last fall.

There is a lot of work to be done on these new products before we can get labels for grass seed. It is essential that growers are behind the research being conducted by the University as well as our own CPS research. We need to be willing to cooperate with on-farm trials as well as giving input to researchers  We will need a united front between producers, suppliers, chemical companies, and the specialists at Oregon State University to get new products like these labelled in a timely manner.

But taking the time to do the proper research is important because we need to know how these products will behave over a longer timeline. As an example, flax is making a come-back here in the Valley. Here's what fall planted flax looks like for those of you who haven't seen it before.

With all the specialty seed crops we grow and the potential crop rotations we have it is essential that we have a pretty good idea what any new product may do to subsequent crops.

Thanks a bunch OSU Weed Science, Carol Mallory-Smith, Andy Hulting, and Dan Curtis for all the work they do and for hosting a great tour with us.


Current Weather Conditions Favor Stripe Rust?

Josh Nelson
CPS Tangent


After the last two years of high Stripe Rust pressure in the winter wheat crop, a common question throughout the spring is; How is the weather affecting Rust pressure? Here is the not so good news.

We observed a fair amount of rust in our wheat fields late last fall. The infections started from volunteer wheat and the high amount of inoculum in the fields after last years harvest.  After infection of the new planted wheat, the pathogen grows within the leaf. Pathogen growth is most rapid at 41 to 51°F (current conditions),  almost no growth is observed at temperatures below 25°F or above 85°F. If temperatures are outside the range for growth for any part of the day, the rust stops growing for that time but resumes growth when the temperatures become favourable again at other times of the day.


Sporulation of the fungal pathogen grows for about 14 days (shorter in some highly susceptible varieties, such as, Goetze) before the pustules erupt through the leaf. Spore production is favoured by high humidity (current conditions). Thus, fresh spores are typically seen in the morning because of cooler temperature and still air are more conducive for sporulation.

During high humidity in winter, most spores remain in small clumps: these are relatively heavy and fall out of the air quickly, so their spread is mostly over very short distances, leading to the ‘hot-spots’ of infection seen in crops in late winter and early spring. When hot spots are observed in a field, decreased yield has already occurred.

This post has not been created to make us feel even worse about the weather. However, even though we may be complaining about the poor conditions, Stripe Rust is loving it.

Growing Degree-Day Definition:
The growing degree-day (GDD), an extension of the degree-day concept, is defined as a day on which the mean daily temperature is one degree above the minimum temperature required for the growth of a particular crop. The GDD is used as a guide to planting times and for determining the approximate dates when a crop will be ready for harvesting.

Plant Growth Regulators on Annual Ryegrass

Pat Boren
CPS Tangent

The use of Growth Regulators (Palisade & Apogee) on Annual Ryegrass has been researched for many years.  In the years 2004-2007 Crop production Services conducted 18 trials on annual ryegrass.  In the last couple years there has been renewed interest in using Growth Regulators (PGR) on Annual Ryegrass.  With this in mind we conducted 20 trials in 2011 using Palisade and Apogee on Annual Ryegrass


The Results from CPS research on using PGR's on annual ryegrass:
·    In 2011, in the 20 trials, 5 trials showed increased yields that would provide a profit after paying for application and product.
·    In our research over all the years there have been cases of very good yield improvement in the 400-600 lb/ac range.
·    There are a large number of variables that complicate the evaluation:
   -timing of application
   -variety; tetraploid vs diploid
   -sheeped vs non-sheeped
   -soil type and drainage
   -weather impact of each year
   -rate per acre
·    We looked at all the variables over all the years in our research, and OSU’s, and determined that positive yield increases are not always predictable. With the use of a PGR on Tall Fescue and Perennial Ryegrass we feel confident of getting strong positive results when recommending the products, however the use on Annual Ryegrass is not as reliable.


The take home message: The decision whether to use a PGR on Annual Ryegrass is not easy.  Work with your CPS fieldman to see if PGR's have a fit on your farm with your annual ryegrass management system.

Neither rain, nor sleet, nor snow, nor hail...

Well, we always seem to pick the best days for plot tours. The guys from Tangent went out Tuesday morning to look at three trial locations with the new chemicals, Alion and Matrix, on carbon planted perennial. We've posted about Alion plots before. We also had some similar trials last year that we were able to look at with Barry Duerk of Bayer Crop Science (we had a video with that one!).


 The carbon-planting plots constisted of varying rates of Alion and Matrix compared to the grower-standard practice of Karmex+Kerb followed by Nortron.  There were a few "mistakes" made on these trials that turned out making these three locations really, really interesting. In one case the applicator sprayed over our plots so we got a chance to see different rates of Alion and Matrix with Karmex+Kerb right over the top.


At another location our research-applicator mixed a double batch so we were able to see what fairly high rates of these chemicals look like. The crop starts getting a little tough at the high rates...so now we know. You know it's a good trial when you have some dead rectangles out there.


We also looked at chemical a screening trial for broadleaf weed control on fall planted Chicory. That was pretty interesting, there were some surprises in there. Some products didn't do as well as you would think and others looked pretty good.


We always learn a lot from trials like these. Overall we were impressed with the new products that will become available to us in the coming years. Thanks to the guys doing all the hard work to put these trials out so we can learn and a big thanks to our customers who are so willing to participate in the research.

If you have any questions about any of these plots or you would like to look at them yourself, please talk to your CPS fieldman.

Filbert Sprays

It is now getting to mid March and the time to apply your Eastern Filbert Blight spray is coming shortly. Be sure to watch your trees for bud swell, bud breakadvanced bud break, and shoot elongation. These are the timings recommended for  fungicide sprays in order to protect your trees from EFB. If you have a susceptible variety it is best practice to do a full 4 sprays for protection. As for resistant varieties a spray at bud break should be applied at minimum for protection. Remeber resistant means it has a good defense, but it is not imune.


If you have any questions regarding EFB control or sprays be sure to contact your CPS fieldman!




The LightSquared Saga

Tanner Sheahan
CPS Tangent

The saga continues. There is a still a battle going on between the desire (and need really) to bring high speed wireless broadband to rural America and the definite need to protect GPS systems from interference. There's at least two sides to every story but I've posted about the basics before; LightSquared ambitiously proposed to roll out a nationwide high speed, 4G mobile broadband network aimed specifically at rural America but they were not able to fit into a spectrum crowded by GPS receivers. GPS is essential don't get me wrong. There's been a lot of stone throwing by both sides. I'll try to give a quick rundown.
The way I understand it is this; many existing GPS receivers in use today (mostly older ones) are "sloppy" in that they receive signals from a wider spectrum of frequencies than is necessary for global positioning. This hasn't been a problem until LightSquared proposed building a network of ground-based 4G-LTE towers that operate near the GPS frequencies, not necessarily overlapping them. If you have an existing GPS receiver that will inadvertently receive the frequency range LightSquared sought to operate in, you have interference. So who is at fault? Who is responsible for retrofitting older GPS's? Should GPS manufacturers foot the bill to tighten the reception on their devices so that we can "clean up" the broadband spectrum? Should LightSquared, or any other company with a similar goal, be forced to pay for improvements to an existing system in order to make room for itself in the marketplace? That has been the fight and it isn't over yet.

The FCC recently ruled in favor of the GPS industry. The ruling shut down LightSquared's current attempt to move forward in building their network until there is sufficient time for the two industries to figure out what to do about the interference. This is a good thing for maintaining GPS functionality.

Farming has come a long way in recent years and mobile technology has too. Right now the two seem to be at odds. There's an explicit need for uninterrupted GPS in agriculture and an equal and growing need for mobile connectivity in rural America. A reconciliation is essential as "farmer's sons and daughters" take over farming operations and technology continues to become a larger part of how we do business out here.

Fishy Fields?

An article I thought was interesting in the capital press.

Grass seed aids fish


SALEM -- Used for erosion control and other environmental purposes, Oregon's grass seed crop long has been known as environmentally friendly.
New research shows the crop provides environmental benefits even earlier, as grass seed fields in the south Willamette Valley now are viewed as invaluable for small native fish during storms.
A study by Oregon State University ecologist Guillermo Giannico found that farm fields provide sanctuary for native fish in floods. Fields inundated with floodwaters provide temporary food sources and shelter from fast waters and introduced fish species during floods, according to the study.
"We have found that native fish have adjusted their behavior to these floodplains, mostly in agricultural lands, to great benefit, Giannico said.
Several factors contribute to grass seed's reputation as an environmentally friendly crop, including that the crop takes up carbon dioxide, has deep roots that stabilize soil and efficiently consumes nitrogen and other nutrients. Also, because most grass seed is grown as a perennial crop, production fields typically are undisturbed for three years at a stretch.
Tom Silberstein, Marion County extension agent, said studies by Linn County Soil and Water Conservation District and OSU show farmers can enhance fish habitat by grading swales and planting native grasses that can survive being underwater for long periods.
"That helps filter the water and slow things down and give fish better habitat," Silberstein said.
Recent feature stories on Oregon radio and print media outlets have highlighted the crop's newfound reputation as a sanctuary for native fish.
