New Traits Don’t Automatically Translate to Highest Yield!

Last weeks announcement by the EPA to register Dicamba formulations for use on Dicamba Tolerant Crops has the soybean world abuzz and for once that buzz isn’t about pollinators! Many of my weed scientist colleagues across the country will be discussing best management practices (BMP’s) for introducing this technology into our agricultural landscape and will put forward recommendations to prolong the shelf-life of this technology. Here is one such example from UNL entitled: Understanding the Roundup Ready 2 Xtend SoybeanWeed Management System. ***Side bar….I decided to highlight this article since UNL never has any highlights in WI and Purdue and IL are like playing the J.V. squad.***

In this brief article I would just like to highlight four points to consider when making soybean variety selection choices for 2017. 

  1. New doesn’t always mean it is automatically better. The WI Soybean program evaluated 200 RR2Y (Roundup Ready 2 YieldⓇ) and 47 RR2X (Roundup Ready 2 XtendⓇ) varieties in 2016. On average across all varieties and regions RR2Y out-yielded RR2X by a significant +1.8 BPA (Figure 1.)
  2. Remember every variety must stand on its own. Use independent trial data and pick varieties that not only perform well (we call them **starred varieties**) but also have the traits you are interested in (e.g. herbicide tolerance). Please see the 2016 Wisconsin Soybean Variety Performance Trials for individual variety performance as we have RR2X varieties starred in each region. 
  3. RR2X soybeans are a stack of herbicide traits and not yield traits (i.e… these traits protect yield, not enhance yield). Remember this point with all pest management traits!
  4. Hey Mr. Ivory Tower if I don’t use this technology my yield loss will be a lot more than 1.8 bu per acre. I am fully aware of the amaranthus spp. train wreck across much of the corn belt and mid-south. We are starting to see herbicide resistance move across Wisconsin as well. I just want to reiterate #2 above that every variety must stand on its own as well as remind growers to use multiple modes of action and consider incorporating other traits such as Liberty Link soybeans into your soybean weed management plans. All of the data and models I have seen suggest that the Dicamba tolerant crops shelf-life will be much shorter than the original RR if we don’t mange this technology correctly.

Start Managing for Fusarium Head Blight Now Before You Plant the 2016/17 Crop

By Shawn P. Conley and Damon Smith

Most WI winter wheat growers dodged the Fusarium head blight (FHB or scab) bullet in 2016; though many farmers especially those in SW WI became so disgusted with dockage and rejections in both 2014 and 2015 they didn’t plant a single acre this year. Therefore as we prepare to put the 2017 wheat crop into the ground here are a few considerations for managing FHB before we drop a single seed.

1.      Crop rotation matters. Data from our long-term rotation studies indicate that wheat following soybean provides the greatest yields. The next best options are wheat following corn silage (6.5% less) then corn for grain (21% less). Wheat following alfalfa or another leguminous crop are also good options, though the N credits following alfalfa may best be served going to corn. Furthermore, background fungal pressure (residue on and in soil) from the FHB fungus will be greater following corn then soybean or another legume, however know that spores that infect your wheat crop can arrive from  outside the field. Please click to see more information on the Top 8 Recommendations for Winter Wheat Establishment in 2016.  
2.      Variety selection matters. Data from our 2015 and 2016 WI Winter Wheat Performance Test shows variable yield and disease performance among the varieties listed. Select those varieties that have both good to excellent FHB (2015) and Stripe Rust (2016) resistance and high yield. When evaluating disease resistance, low numbers for both incidence and severity can be helpful, but the major focus should be placed on  incidence (measure of the number of symptomatic plants in a stand).
3.      Application timing matters. One of the biggest challenges year in and year out is improper fungicide application timing. Our data suggests that on susceptible (Hopewell) or moderately susceptible varieties (Kaskaskia) equal efficacy of the fungicide Prosaro at a rate of 6.5 fl oz/acre can be achieved when applied between Feekes 10.5.1 (anthesis) and 5 days after anthesis. Given the variability of head emergence and anthesis across a landscape it may prove best to wait a few days until the whole field is flowering than to apply too soon.  If the extruded anthers have turned from yellow to white across the whole field then you are likely too late. Remember it roughly takes a wheat head 7 days to completely self-pollinate.

4.      Choose the right fungicide class. Make sure you use the appropriate fungicide product and class to manage FHB. The label for products containing strobilurin active ingredients (FRAC group 11) ends prior to flowering. Late application can actually lead to increased mycotoxin levels. Triazole containing products (FRAC group 3) are recommended for FHB control. For a list of products and efficacy ratings, visit the Field Crops Fungicide Information Page
5.      Harvest timing and flash drying. The word on the street is that if FHB appears to be a problem in 2017 elevators will push growers to harvest early (18% moisture or higher) and subsequently dry grain to mitigate mycotoxin levels. While drying grain to 13% or less moisture is a good storage practice, know this process may kill the pathogen but any mycotoxin levels already in the grain will not dissipate. Vomitoxin is a very stable molecule and IS NOT degraded by heat, freezing, or drying.    

Small Grains Harvest and Combine Fires

From John Shutske:Professor & Extension Specialist; Biological Systems Engineering
It looks like wheat harvest is rolling in parts of the state.   I saw a post from a friend in New Glarus saying they’d started late yesterday. Just a quick reminder on combine fire prevention and protection —  “Protection,” because SOME machines will burn regardless of how hard you work at it.  So you need to know what to do to minimize the damage.  Over the years I (or my former students) have done a bunch of investigative work on about 12,000 fires (combines, tractors and other specialty harvesters).  We’ve learned a lot….
See:
Here are some specific reminders:

  1.  Keep the engine compartment as clean and clear of debris as possible.  Caked/oily residue means there’s a leak someplace.  Fix it. 
  2. Listen closely for unusual noises and pay attention to warning lights and sensors that could indicate bearing/belt/and other drive component issues.  Fix them. 
  3. Many combine fires are ignited by the electrical system – blown fuses, flickering lighting, etc. are all signs that you might have damage.  
  4. The ABC dry chemical fire extinguisher is probably still the most cost-effective and overall effective type of extinguisher.  The bigger the better (at least 10 pounds).  Mount extinguishers (recommend at least two ten-pounders) where they can be grabbed quickly in the cab AND/OR from the ground.  
  5. If a combine does catch fire, pull it away from any standing crop quickly.  Shut off the engine.  The longer the fire burns, the more difficult it will be to put it out.  If the engine is left running, it will be almost impossible to extinguish (even if the fire department shows up)! 
  6. Grab your extinguisher if time allows and get out.  Call for help.  It is not always possible to put out a vehicle fire with a handheld extinguisher.  A second one is often needed, even on a smaller fire. 
  7. Always consider PERSONAL safety.  A combine fire that gets into a fuel, oil, or other flammable liquid system will burn hot.  Even more so if a tire is involved.   A machine can be replaced.  A life cannot. 
  8. If you’ve used an extinguisher (even for a short burst), it MUST be recharged.  If you’re not sure where to recharge and re-tag your extinguisher, call your fire department.

Some Risk for Wheat Crop Injury From Saturday’s Cold Temps

Saturday mornings cold temperature may lead to crop injury in low lying areas across Southern WI. Based on the development in our wheat plots the highest risk for yield loss would likely come in the southern tier of WI counties. The wheat at our southern locations are either at the Feekes 8 (flag leaf visible) or 9 (flag leaf ligule and collar visible) crop growth stage dependent upon variety. 
 

Image 1. Feekes 9 crop growth stage at Arlington WI on 5/16/16.

Crop injury at these growth stages would occur in the 24 to 28 (duration of up to two hours) degree F temperature range. We did not see this temperature extreme at our Arlington location (Image 2; low temp of 30.5) however I have heard reports of extended cold temperatures in the sub 28 degree F range.   
Image 2. Arlington WI weather data for the last week.

The two types of crop injury I would be concerned about include stem damage and spikelet (head) injury. In Image 3 below you can see the brown discoloration and water soaking to wheat stems caused by freeze injury. This  injury eventually lead to severe lodging among select varieties (Image 4). If you see this type of injury it would be best to take this field as a forage crop ASAP. 

Image 3. Freeze damage to wheat stem.
Image 4. Subtle difference is crop growth stage led to severe lodging due to freeze injury.
The other type of injury would be direct damage to the wheat head. Peel back the boot and expose the wheat head. If healthy individual florets on the spikelet will appear pale green (Image 5). If they begin to appear water-soaked or off colored (brown) then crop injury occurred).  
Image 5. Healthy spikelet and florets.
For more detailed information I have attached a link to a publication entitled Spring Freeze Injury to Kansas Wheat.  For ease I have also removed a table from that publication to stress the importance of growth stage on damage potential  (Table 1).

Soybean Management Strategies to Facilitate Timely Winter Wheat Establishment in 2016

Winter wheat acres across WI have declined over the past few years due to high corn and soybean prices and late grain harvests, however current economic realities suggest an opportunity for increased wheat acres moving forward. As farmers get ready to kick off the 2016 growing season here are a few suggestions to help get your 2016/17 winter wheat crop established on time.

    • Plant early. If weather and soil conditions allow for it plant the acreage you intend to go to winter wheat first. This is regardless of which crop you plan to follow (soybean, corn silage or field corn). Remember the optimal planting date window for most of our WI winter wheat acres is the last week of September through the first week in October. In Figure 1 below you will notice that for every 3 days planting is delayed we see 1 day delay in harvest, so delaying planting by one week equates to about 2 days later maturing. However when planting is delaying past June 1stit turns in to more of a 1: 1 relationship. Also remember in WI it normally takes another 5-8 days for the soybean crop to move from R7 to R8 (full maturity).

      • Crop rotation matters. Our long-term rotation data suggests winter wheat yields are greatest following soybean, followed by corn silage and lastly corn for grain.  Therefore plan your rotation accordingly to maximize yield and system efficiency.
      • Consider an earlier maturity group soybean. Plant a high yielding, earlier maturity group soybean to help get that soybean crop harvested on time. Though later maturing varieties “on-average” produce the greatest yields, data from our 2015 WI Soybean Variety Test Results show the maturity group range that included a starred variety (starred varieties do not differ from the highest yield variety in that test) was 1.9-2.8, 1.1-2.4, and 1.1-2.0 in our southern, central and north central regions respectively. This suggests that the “relative” maturity group rating is trumped by individual cultivar genetic yield potential. Therefore growers have options to plant an early maturity group soybean that will be harvested on time and not sacrifice yield.
      • Manage for the system not necessarily the crop. If you are serious about maximizing wheat grain and straw yield on your farm one of the biggest contributing factors for both of these in WI is timely wheat planting. Make management decisions to facilitate that. *We all know what inputs can extend maturity that don’t necessarily guarantee greater yields. So instead of listing them and fielding angry emails I am being strategically vague here*  As a producer is it better to sacrifice 0-2 bushels of soybean yield or 10-20 bushels of wheat grain yield and 0.5 tons of straw?  

      As we all know mother nature holds the ultimate trump card on whether we will get our winter wheat crop established in that optimal window. These aforementioned strategies are relatively low risk to the farmer and regardless of what weather patterns we run into are agronomically sound.

      Soybean Planting Date and Maturity Group Considerations for 2016.

      Authored by Adam Gaspar and Shawn P. Conley

      Early May planting in Wisconsin has been documented to increase yield due to increased light interception (Gaspar and Conley, 2015).  In theory, earlier planting can potentially intercept greater amounts of solar radiation due to a longer growing season and therefore longer maturity group (MG) soybean varieties may be better suited to maximize yield if they can mature before a hard fall frost.  2015 provide many WI growers with a longer than normal growing season due to favorable early spring planting condition and a later than normal fall frost.  Yet, in some instances (weather or logistical problems) planting can be delayed or replanting may be needed. Therefore, investigating the effect of different MG’s at multiple planting dates across the state would be useful.  Thus, DuPont Pioneer and the Wisconsin Soybean Marketing Board have funded a 3-year study to examine proper MG selection at 5 different planting dates across the state to maximize yield.  So let’s look at the 2014 and 2015 preliminary data:

      Trials were conducted at Arlington, Hancock, and Spooner, WI.  The five planting dates at each location were planting roughly on: (1) May 1th, (2) May 20th, (3) June 1st, (4) June 10th, and (5) June 20th.  Planting after June 20th is not recommended in WI.  Two varieties within each realistic MG from a 2.5 all the way down to a 00.5 were tested depending upon the location and planting date and are displayed in Table 1.  
      Table 1. Maturity Group’s tested within each location and planting date.

      1.5, 1.0, 0.5
      0.5, 0.0, 00.5
      I’ll start with the easy and redundant part, get your soybeans in the ground ASAP to maximize yield.  This is very evident again in this trial, where Figure 1. shows the effect of planting date across all MG’s (varieties) tested in 2014 and 2015.  Interestingly the yield decline for delaying planting was similar between years at Hancock and Spooner of approximately 0.46 and 0.23 bu/a/day, respectively.  However, at Arlington the yield decline was not as severe in 2015 compared to 2014, which was likely due to the abnormally late fall in 2015.  Never the less, if the soil is fit, soil temps are near 50 ˚F, and the forecast is favorable….. get the planter rolling!

      Figure 1. Dots represent the mean yield within each planting date for each location.  The average yield loss per day for delaying planting past May 1st is presented in the legend.
      However, the question still remains for many producers, should I use a longer maturating variety in early planting situations (very possible again in 2016) and should I switch to an earlier maturing variety when planting is delayed?

      The numerically highest yielding MG for each planting date and location.  MG that are bold and colored red were significantly higher at the  P ≤ 0.05

      Combining the 2014 and 2015 data, 8 out of 15 location x planting date combinations displayed a significant effect of MG on yield (Table 2). 

      At Arlington and Hancock, using the longest MG resulted in the highest yield within dates 1-4 and was significant 7 of 8 times. Within planting date 5 the shortest MG (0.5) yielded the highest numerically, but this was not significant and the MG 1.5 varieties did not mature before the fall frost in 2014.  Therefore, planting a portion of your acres to slightly longer MG than normal within May can provide the opportunity for greater yields with no additional dollars spent.  In addition, when planting is delayed into June, switching to a variety much more than 0.5 MG earlier than a full season variety (2.5 MG) may limit yield potential.  However, if planting is delayed until mid to late June or more likely replanting is needed, a variety that is at least a full MG earlier should be considered to avoid fall frost damage.
      At Spooner, MG selection was not as critical and only planting date 5 saw a significant effect of MG on yield where the 0.5 MG out yielded the 0.0 and ultra-early 00.5 MG varieties.  Therefore, northern WI growers can maximize yield and avoid fall frost damage using varieties within a narrow MG range (1.0  – 0.5). However, growers may consider trying a slightly longer maturing soybean on a portion of their acres when early planting is possible, because of the “potential”, but not guarantee, for higher yields with no additional dollars spent.
      In conclusion, variety selection heavily based upon the MG is not a silver bullet to increasing yields, however it does provide the “potential” for higher yields with no additional dollars spent. Therefore, growers should give consideration to MG when selecting varieties, but past local and regional performance, disease package, scn-resistance, and etc. should take precedence.

      Wisconsin Soybean Marketing Board Continues Free Nematode Testing Program for 2016

      Four out of every five animals on earth today is a nematode so it is not surprising that agricultural fields are home to many nematode species. Fortunately, most nematodes are beneficial to crop growth and soil health because their activities help decompose crop residues and cycle nitrogen and other nutrients. Pest nematodes do not threaten yield if their numbers remain low. The key to avoiding population explosions of nematode pests is to be proactive – know what the situation is and take appropriate measures when nematode numbers indicate a problem is brewing. 
      The WSMB sponsors free nematode testing to help producers stay ahead of the most important nematode pest of soybean, the soybean cyst nematode (SCN) (Figure 1). Eggs of SCN persist in the soil between soybean crops so a sample can be submitted any time that is convenient. The soil test report indicates the number of eggs in the sample and is useful for selecting the right variety for the next soybean crop. Retests of fields planted with SCN-resistant varieties over multiple years shows how the nematode population is responding to variety resistance and provides an early warning should the nematode population adapt to host genetics.

      Figure 1. WI Counties Confirmed to Have SCN as of 2013.

      In 2016, the WSMB is again offering the expanded nematode testing program to include other pest nematodes in addition to SCN. These nematodes are less damaging to soybean than SCN but can cause enough yield loss to warrant treatment. As is the case for SCN, there are no rescue treatments for nematodes so the primary purpose of this year’s soil test is to plan for next year’s crop. Soil samples collected in corn for nematode analysis have predictive value for explaining yield if they are collected before the corn V6 growth stage. Sampling early in the season will provide information about the risk potential for the current corn crop AND the next soybean crop.
      The assays used to recover nematode pests other than SCN in soil require that the nematodes are alive. So, it is important to keep the samples moist and at least room temperature cool. Collecting a sample that includes multiple cores ensures that there will be plenty of root pieces to assay. It is not necessary to include live plants in the sample. The soil test report will indicate which pest nematodes are present and at what quantities and their damage potential to soybean and corn based on the numbers recovered.

      Free soil sample test kits are available now and can be requested at (freescntest@mailplus.wisc.edu).
       

      For more information on SCN testing and management practices to help reduce the losses from this pest, please contact: Shawn Conley: spconley@wisc.edu; 608-262-7975 or visit www.coolbean.info
      Remember the first step in fixing a nematode problem is to know if you have one! The WSMB sponsored nematode testing program provides you that opportunity.

      Factors to Consider While Assessing Your 2016 Winter Wheat Crop Stand and Spring Nitrogen Timing

      As the snow begins to melt and we finally put the 2015/16 winter behind us, many growers and consultants alike are beginning to venture out to their winter wheat fields to assess winter injury and nitrogen timings. Though it is a bit premature to make any rash decisions regarding crop destruction here are a few considerations for assessing your spring 2016 winter wheat stands.

      1. As you look across your wheat landscape vibrant green patches will be interspersed with drab brown areas. The brown areas do not necessarily indicate those plants are dead.
        2016 Arlington Winter Wheat Variety Trial – Roadside Assessment
        2016 In Field Stand Assessment
        2016 Planting Depth and Tiller Assessment
        Growers and consultants can either reassess in a week or pull plants from the field and place in warm environments. Milk houses and kitchens work perfect. Root regrowth will appear from the crown and will appear as vibrant white roots as shown below.
        Spring Root Regrowth in Winter Wheat

        If plants do not recover our critical threshold for turning over a field is 12 to 15 live plants per square foot. Below this threshold is an automatic replant.

      2. Hot off the press (word press that is)…the N timing decision just got easier.  New research from Dr. Carrie Laboski’s program indicates that the optimal time to apply nitrogen to wheat in WI is green-up regardless of tiller count. For more detailed information check out her new blog article here entitled: Time your spring nitrogen applications to maximize winter wheat yield.
      3. Lastly remember that wheat grain in itself is only part of the revenue you capture with winter wheat. The price of winter wheat straw remains strong so please consider that revenue stream before any replant decisions are made.
