Field Bindweed and Wild Carrot Control

Jason Bennett

With the end of Summer fast upon us it is time to start thinking about two weeds that are a problem for most people who farm in the Willamette Valley, Field Bindweed and Wild Carrot.

 Field Bindweed
 Field Bindweed is a long-lived deep rooted perennial weed that often climbs or forms dense tangled mats.  Bindweed can be a problem in just about anything you raise in the Valley and with the rain we received on Monday now is the time to control it.  There are many products that may burn the bindweed back or keep it at bay, but there are only two that will eventually kill it.  One is Glyphosate this obvious only works when dealing with a fallow piece of ground or if a field is going to come out.  The other product is Paramount.  Paramount is a systemic herbicide with plant uptake occurring by both foliage and roots. Paramount can effectively control field bindweed if applied in the fall prior to a killing frost when the plant is at least 4 inches long and actively growing.  Make sure to talk to your fieldman about the crop rotation restrictions that come along with this product, and the other products that are also available.  Bindweed is a weed that will take 2-3yrs of Fall treatment of either product to keep control of so be warned once you start make sure to finish.

  Wild Carrot
 Last but not least is everyone's favorite, Wild Carrot.  This weed is starting to show up any where and every where.  Wild Carrot invades our fields by ditch banks and/or field borders, and that is where we need to concentrate on controlling it.  The best product for controlling Wild Carrot is Chlorsulfuron or Glean as we know it.  This product is only allowed to be applied in crop areas.  For fence rows or right of ways the product that is labeled is Telar it has the same percentage of Chlorsulfuron as Glean does but is only labeled in non crop areas.  Once the Wild Carrot moves into a Tall Fescue field the most effective product is Glean, Tall Fescue is very tolerant of Glean in the late summer early fall.  The Glean applications need to be done on Tall Fescue by Septemeber 15th.  Talk to your fieldman to figure out when and if this would be the good option for you.

CPS Soybean Variety Trial

Left Dyna-Grow and  Right Legend
 In an effort to continually look outside of the box CPS has put together a Soybean variety trial. During the first year of the trial the objective was find varieties that would reach full maturity here in the Willamette Valley. Two promising varieties are from Dyna-Grow and Legend.

Hand Rouging Blue River 09F8

 Another main objective of the trial was to grow the Soybeans with minimal input. Our herbicide program did involve both a pre-plant incorperation treatment and a post emergence application when the beans were 4-6 inches tall. We only watered twice to induce the varieties to mature earlier. Cameren is seen here cleaning up some of the weed escapes.

Eric and Thomas evaluating Variety Trial
As with all of our trials we are very appreciative of both grower and industry support. In the foreground is Eric Horning of Horning Farms. Eric not only provided the ground for this trial, but also applied the two shots of water. In the background (right) is Thomas Endicott V.P. of Business Development from Willamette Biomass Processors, Inc. Thomas has shared a number of varieties and production ideas with us. In the background (left) Cameren is still rouging.

Please ask your CPS field represenative for more informaion about our trial or line up a time to make a tour.

Here is the OSU PNW Irrigated Soybean Production Guide.

Vole baiting in Grass Fields

This is a reminder as the end of August approaches that means we are coming to an end of the broadcast application of ZP on Grasses grown for Seed.  August 31 is the last day to broadcast ZP bait on Grasses grown for Seed, after this date you are only allowed to hole bait.  Make sure to talk to your fieldman to see if you have any fields that need to be baited.  Take a look at the ZP label and talk it over with your fieldman.

Welcome Back!

Welcome back!  Harvest is winding down, ground is being worked, and we're starting to think about topics for the blog again.  I hope you all had a safe harvest season.  We'll be posting to the website more regularly as we move into the fall season.  Feel free to leave comments on our posts.  You can also email us or talk to your CPS fieldman.

Here are a few things we'll be covering in the next couple weeks.
  • ZP Rodent Bait grass seed label
  • Fall weed control
  • Variable rate soil amendment applications
  • Fumigation update
    There are a few more things we've thought of that I'll leave unnamed for now...gotta have something to surprise you with.

    Thanks for taking a look and I hope you find the Tangent blog to be a great resource.  Again, please feel free to leave comments or contact your CPS fieldman with ideas or feedback.

    Black Tip in Goetze Wheat

    Tanner Sheahan
    CPS Tangent

    We received the following email as a forward from Andy Hulting, OSU Extension.  The original email was a description of black tip in Goetze winter wheat by Mike Flowers of OSU Extension.
    Over the last week or so I have been hearing from multiple sources about black tip (or point) and sprout damage being reported in Goetze.  These reports appear to be isolated to Goetze.  There also seems to be a lot of confusion about why this is happening.

    Black tip is a fungus that is found on mature grain.  This typically occurs when mature grain stays moist for prolonged periods.  Thus, black tip is typically found in irrigated and lodged fields that dry out slowly.  Given the cool morning temperatures that do not allow the dew that formed overnight to dry quickly it is not surprising that black tip is being found this year.  Why only (or mostly) on Goetze.  Goetze is an early maturing variety (about 2-3 weeks earlier than Tubbs 06 and Madsen) and thus can have a longer exposure period to these conditions.  Stripe rust on the head may have also dried down the grain quicker than expected and thus lengthened the exposure period.  In any case, black tip is not normally a major concern.

    Sprout on the other hand is major concern.  Given the weather conditions it was very surprising to hear some of the high levels of sprout being reported.  It appears from further grain testing that these high levels of sprout may be false positives.  The black tip found on the grain is making it difficult for grain graders to properly determine if sprout is present.  It is important to note that when grain is delivered it is examined visually for sprout damage and not through a falling numbers test, which would be more definitive.  Therefore growers who are delivering grain and receive a high sprout level should ask for a re-examination by the Federal Grain Inspection Service (FGIS).  Growers will be charged for this re-examination (~$12 per sample) but sprout levels have been reduced or eliminated when re-examined.  This can have major economic implications for growers when dockage due to sprout is reduced or eliminated.

    Please pass this information along to any who might be interested.
