Early September Frost - Impact on Soybeans

September 5, 2017  - Pinawa, Winnipeg, Whiteshell and Steinbach overnight forecasts, Environment Canada is stating there is a risk of frost. 
 
Whether or not there is yield loss in soybeans depends on two factors.  One is how cold it gets and how hard it freezes.  We won’t know the story on that until tomorrow.  The other factor is the growth stage the soybeans are at and that is determined by examining the pods on the plant.  It is all about the pods, so don’t get distracted by the condition of the leaves.  The more advanced/mature the soybeans pods are, the less the potential yield loss.
Manitoba Pulse and Soybean Growers has a maturity guide on their website that will provide you with excellent pictures and descriptions of the growth stages we are now seeing in our fields.  Use it as your guide in determining where your beans are at.  Click on the link below to access:
http://www.manitobapulse.ca/wp-content/uploads/2015/08/Soybean-MATURITY-GUIDE_Apr-2017_WR.pdf
 
In terms of yield loss, use the following as a guide:
  •  Frost during the R5 stage can reduce yield by 50%-70%.
  •  Frost at the R6 stage can reduce yield by 20%-30%.
  •  Frost at the R7 stage can reduce yield by only about 5%.
  •  At the R8 stage no yield reductions are expected.
You will always find some variation around predictions of yield losses due to frost in soybeans.  This is to be expected.  There is no absolutely right answer.  No crop is uniformly at one growth stage and every frost event is unique in how it plays out.  The information above is merely meant to serve as a guide.
 
 

Getting good strip yield data with calibrated yield monitors

Last year some of my corn nitrogen plots yielded over 200 bu/ac with the University of Manitoba plot combine.  I refused to report such astounding yields until the electronic weighing system had been verified with bagged and weighed yields. 
Likewise scrutiny and calibration is required when using yield monitors for strip trial tests.  Last year we compared harvest weights from strip trial yields in on-farm-tests looking at nitrogen and wheat protein.   Several farms had scaled grain carts in addition to their combine yield monitor (Figure 1) and all plots were measured with a weigh wagon.  Figures 2 and 3 shows the trends of grain cart and yield monitor data versus the weigh wagon yield (solid line).

Figure 1.  Comparing yield measuring systems – combine yield monitor, scaled grain cart and weigh wagon.

Farm A – with scaled grain cart used to calibrate yield monitor.  Yields follow trend of weigh wagon weights and are within 2 bu/ac.
Farm B – A seldom calibrated yield monitor with yields not corresponding to weigh wagon weights and up to 6 bu/ac less.
 
Yields from a perfectly calibrated yield monitor and grain cart would fall on the black line in the graphs above.  Farmers with accurate, scaled grain carts were usually calibrating their yield monitors in each field and producing very similar results as the weigh wagon (such as Farm A).  Those that were calibrated on earlier fields or earlier in the season were unable to measure the subtle yield differences in this study and may lead to erroneous conclusions.
So if yield monitors are being used to measure strip trial yields, I encourage growers to calibrate often with their scaled grain carts or a weigh wagon if available.  The measurements we made were in dry wheat but if crop strips are of varying moisture content, more frequent calibration may be warranted.

Potassium Deficiencies in Maturing Crops

Several of our maturing crops are now exhibiting deficiency symptoms that are too late to correct, but important to address for next year. 
Potassium (K) is often overlooked in much of Manitoba due to our naturally high K levels in clay and clay loam soils.  But deficiencies on lighter textured soils are increasing – particularly with soybeans. 
   Mild potassium deficiency symptoms on upper leaves in August.
Potassium deficiency often shows up during pod and seed fill, since soybeans remove 1.4 lb K2O/ bu of grain, the heaviest rate of removal of any grain crops.  As K is translocated out of leaves to fill seeds, the deficiency shows up as yellowing and later necrosis of the leaf margins.
Sometimes odd strips occur of alternating deficient and normal soybeans occur in fields.  These are often related to a previous canola or cereal swath that has had the K leach out of the swath into the soil beneath, and hence marginally increasing K supply in that strip.
If either of these symptoms are observed, a K deficiency can be readily identified with a traditional soil K test and a recommendation will be made for future K fertilization.

Managing Water Hemlock in Hayland and Pasture

Like many carrot family weeds, spotted water hemlock populations in Manitoba have been spreading, likely due to w
et conditions over the last several years.  Managing populations in hayland and pasture is recommended since hemlock species are extremely poisonous to humans and livestock.
Identifying Spotted Water Hemlock
Proper identification is important since spotted water hemlock looks similar to water parsnip, another carrot family weed commonly found growing in wet areas across the province.
 
 
Managing Hemlock
All parts of the hemlock plant are poisonous.  Young leaves and re-growth after treatment may attract livestock, especially if other food sources are limited or less palatable.  Access to water hemlock by livestock should be restricted while populations are being managed.
The following methods can be used to control or suppress spotted water hemlock in hayland and pastures:
-        Hand pulling (wear gloves!). Pulled plants can be left in the sun to dry.  Once dry, plants can be disposed of in an area away from people and livestock.
-        Repeated cutting or mowing.
-        Herbicide spot treatment or foliar application.  Glyphosate, 2,4-D and picloram have activity on water hemlock.  Refer to the label for grazing and haying restrictions.
-        Cultivation.
Feeding Hay and Greenfeed with Water Hemlock to Livestock
Feeding hay with some water hemlock in it to livestock is okay, according to research from the US, as long as the hay (and hemlock) is thoroughly dried.  The curing process allows the toxins in water hemlock to dissipate, reducing the risk of livestock poisoning.  Hay with water hemlock should either be fed last to allow for maximum dissipation of the toxins or occasionally interspersed with hay not contaminated with water hemlock.  If possible, contaminated hay should not be fed continuously to pregnant livestock, as there is evidence that chronic exposure to water hemlock toxins can result in birth defects.
Unlike hay, greenfeed contaminated with water hemlock should not be fed to livestock or used for silage or baleage.  Testing done in Oregon found that ensiling causes certain toxins to accumulate rather than dissipate and remain at levels that are unsafe for livestock consumption.

Poisonous Plants of the Carrot Family

It’s Probably Not Giant Hogweed
Because of our experience with crops and weeds, it’s no surprise that the general public often turns to agronomists for plant identification and management advice.  And it’s usually about this time of year – when Ontario puts out giant hogweed advisories and big white umbels are in bloom across Manitoba – that these calls start to pour in.

Cow Parsnip

Fortunately, it’s probably not giant hogweed (Heracleum mantegazzianum) since that invasive species has yet to be found in our province.  It’s more likely another member of the carrot family – cow parsnip (Heracleum maximum).  Unlike its giant cousin, cow parsnip is native to Manitoba and non-invasive.  It’s also very attractive to pollinators.
But even though it’s probably not giant hogweed, it’s still best not to touch it.  Because, much like its giant cousin, the sap of cow parsnip may cause dermatitis when in contact with exposed skin.  Symptoms include photosensitivity, a rash and/or blisters.  Reactions to cow parsnip sap are generally much less severe than those to giant hogweed sap.
Information on identification of cow parsnip and giant hogweed is available from Manitoba Agriculture:

Post Anthesis Nitrogen Applications for Wheat Protein

When wheat prices and protein premiums/discounts are high, there is renewed grower interest in late N applications to enhance wheat protein.  Following is an old recipe we have recently evaluated in on-farm-tests and small plot studies.
1.       Apply 30 lb N/ac, which is 10 US gallons of UAN solution (28-0-0) diluted with 10 gallons water
2.       Apply with flat fan nozzles
3.       Apply 7-10 days following anthesis (so about 7-10 days after your fusarium head blight fungicide)
4.       Apply in morning or evening when temperatures are less than 20o C.  Avoid heat of the day.
Under such treatments we have observed leaf burn of 8-15% of the leaf area without detrimental impact on yield.  The one instance sprayed at mid day in high temperatures reduced yields by  6 bu/ac with 31% leaf damage . Protein increase ranged from 0-1.5% and averages are reported in Table 1.
Table 1: Effect of post anthesis N (PAN) on wheat class yield and protein (2015-16).

If attempting such a practice, leave a check strip – not so much for yield determination, but to gauge the success in protein increase.
 

Spotted Wing Drosophila Surveillance Program- Update July 11, 2017

Low levels of Spotted Wing Drosophila (SWD) females and males (1-2 per trap) have been found in traps in southern Manitoba.
 
Berry Crops at Risk
Raspberries: As raspberries start to change colour and ripen in mid-July, an insecticide could be applied to protect that harvest which is expected to start in 1-2 weeks time, then repeat with an alternate insecticide 7-10 days later (see list and link below).
 
Late Season June-bearing Strawberries: At risk now would be the later picking of late season June-bearing strawberries, so may not be worth spraying unless significant harvest remaining. 
 
    • As more wild hosts and other commercial berry crops begin to ripen, expect SWD numbers to start building up significantly by late July.
    • Berries are susceptible to SWD infestation from the start colour starts to appear on the berry all the way through harvest. Producers have many chemical control options to control SWD (see link below).
    • It is important to constantly rotate every application through different insecticide chemical groups to avoid potential insecticide resistance issues with SWD.

Managing Winter Killed Hay and Pasture Fields

Severe winter weather can cause increased winter kill of forage stands in Manitoba.  Alfalfa is prone to winterkill if the crown (the point on the plant from which all the stems grow from) is oxygen deprived due to ice cover, or if it freezes to -12oC or colder for 2-3 days. 
 
If it is decided that a stand is sufficiently compromised that renovation is needed, some factors need to be considered.  Alfalfa plants produce toxins (called medicarpins in the leaves) that reduce the germination and growth of new alfalfa seedlings.  Older stands have produced medicarpins longer and therefore have more of a build up or concentration in the soil around the plant where the leaves drop to in the fall of the year.  Generally the medicarpins are within 41 cm of the crown, so reseeding or over seeding alfalfa into these areas results in limited success. 

Medicarpins break down over time, so a break from alfalfa for a year is sufficient time to allow for successful re-establish of alfalfa on that field. 

Sod or no-till seeding can be a successful way of renovating old stands so long as the above information has been considered.  These are some tips for successful germination and emergence of sod seeded forages.
  • Soil test and apply fertilizer as required, especially phosphorus (P).
  • Suppress competition from the existing vegetation, especially under drier soil conditions.  1.5 L/acre glyphosate (480 g/L formulation) will suppress the vegetation for about 60 days.
  • Use seeding equipment appropriate for sod seeding conditions.
  • Packing (in furrow or land roller) will slow drying of the soil and allow seeds to imbibe water more easily.
  • Plant shallow, i.e. 19 mm or less.  Small seeds do not have enough energy in the seed to emerge from deep plantings.
  • Check seeding depth and packing regularly while seeding.

    Manitoba Weed Update - June  21, 2017

    Despite rainy and windy conditions, early post-emergent herbicide applications are nearing completion in most crops.  Emergence of cool season annual weeds was relatively unaffected by earlier cool, dry conditions while emergence of warm season annual weeds was delayed, resulting in herbicide staging issues for some producers.  Emergence of warm season annuals, like redroot pigweed and barnyard grass, is now well underway due to recent rainfall.
Weed Identification
Weed identification form can be found here.
Weeds submitted to Manitoba Agriculture for identification in the previous week include:

 

  • Black nightshade

Black nightshade (Solanum nigrum) is a warm season annual problematic in potato, dry bean and soybean production.  What to look for: small seedlings with pointed ovate cotyledons, currently in the cotyledon to early true leaf stage (see picture submitted to MB Ag).

 

  • Galinsoga species

Hairy galinsoga (Galinsoga quadriradiata) and smallflower galinsoga (Galinsoga parviflora) are annual species also referred to as ‘quickweed’ based on their ability to set seed within only weeks after emerging.  What to look for: toothed, opposite leaves and ‘club’ shaped cotyledons.
 

 

  • Oak-leaved goosefoot
    Of the various goosefoot species coming in for identification, oak-leaved goosefoot (Chenopodium glaucum) has been the most common.  What to look for: goosefoot shaped leaf, often with distinct yellow-green veins.  Stems may be red and green to red.  Typically grows more prostrate than lamb’s-quarters.  Oak-leaved goosefoot does especially well in wet and/or saline areas.
Weed Management Issues
Manitoba Agriculture staff received herbicide drift complaints and are providing advice accordingly.  Talking to the applicator should always be the first step in a suspected drift incident.  Herbicides involved in the drift complaints to date include glyphosate, group 2 and group 4 herbicides.
 

 

Don’t Overlook Group 2 Herbicide Resistance

You’ve probably read about media dubbed ‘superweeds’ like glyphosate-resistant palmer amaranth and giant ragweed.  Glyphosate-resistant weeds often earn this distinction because they are viewed as a greater management hardship for producers than weeds resistant to other herbicide mechanisms of actions (MOAs).  And maybe rightly so.  Farmers dealing with glyphosate resistant weeds elsewhere in the world have been reduced to tillage and hand rouging for weed control in some crops.
 
But, while glyphosate use dominates the Roundup Ready corn, soybean and/or cotton rotation in the US, group 2 herbicides play an (equally?) important role in our more diversified cropping system.  For example, group 2 herbicides are used in crops like alfalfa, corn, dry beans, field pea, potato, soybean, sunflower, and in Clearfield and other group 2-tolerant crops.  These herbicides are also a popular choice for group 1-resistant grassy weed control in cereals.  
 
The point of this article isn’t to downplay the importance of glyphosate resistance but to elevate consideration of group 2 resistance.  In Manitoba, over 10 weed species are known to have biotypes resistant to group 2 herbicides.  And herbicide-resistant weed surveys led by AAFC indicate that the prevalence of certain species is increasing (Figure 1).
 
Figure 1:  Prevalence of group 2 resistance in Manitoba in 2002 and 2008 as a percent of the weed species population surveyed (Beckie et al).
 


The following practices can help reduce the risk of developing herbicide resistant weeds and/or managing existing resistant weed populations:
  • Diversifying your crop rotation;
  • Using multiple herbicide MOAs effective on target weeds (e.g. herbicide ‘layering’,  tank mixing);
  • Practising good basic agronomy (variety selection, seeding rates, etc.);
  • Judicial use of tillage.

If you suspect group 2 resistance in a weed species on your farm, it’s best to verify this by herbicide-resistance testing.  Unfortunately there‘s no quick method - seed from the suspect population needs to be allowed to mature and collected.  Samples can be submitted to AgQuest for testing in Manitoba.

In my opinion, knowing if you have group 2 resistance and assessing your risk factors is worth it.  Because while glyphosate resistance is grabbing headlines, group 2 resistance may be quietly growing in your fields.

 

Testing Weeds for Herbicide-Resistance

Do you have weeds that survived this year’s herbicide application(s)?  Since there are many factors that can contribute to weed escapes, consider:
  • The distribution of escaped weeds:  Herbicide-resistant weeds tend to occur in patches as opposed to geometric patterns (e.g. spray miss) or throughout the field (e.g. tolerant weeds).
  • Possibility of reduced herbicide efficacy:  2016 was a challenging year for weed management due to untimely and excessive rainfall.  In many cases, weeds escaped because of herbicide application timing with respect to weed growth stage, limited herbicide choices because of crop growth stage (when producers finally could get on their fields) and product rainfastness.
  • Weed species:  Annual weed species, like wild oat, green foxtail, cleavers, kochia, hemp-nettle, smartweeds, ragweeds and wild mustard, may be more likely to develop resistance compared with other weed species.  Because the development of herbicide-resistance is based on chance, resistant weed patches are typically a single species, as opposed to non-resistant weed escapes, which may affect multiple weed species.


Suspect weed escapes can be confirmed as resistant or susceptible by herbicide-resistance testing.  For most weeds, dry, mature seed is required for the analysis.  Although more is better, many labs require at least 100 g of small weed seeds (e.g. cleavers) and 200-250 g of large weed seeds (e.g. wild oat).  Weed seed samples should be submitted by December 31, 2016 to either:

For suspected glyphosate-resistant kochia, a genetic-based tissue test is also available from the Pest Surveillance Initiative: http://www.mbpestlab.ca/field-testing/.  In this case, about 5 to 10 g of green plant tissue (e.g. leaves and stems from plant tips) is needed for the analysis.  Samples should be placed on ice and shipped immediately after collection.  The advantage of the genetic test (vs. seed analysis) for kochia is the ability to determine resistance in-season.

Waterhemp Now A Manitoba Weed

 
Can you identify the plants in the two pots below?
 
The plants on the right are redroot pigweed (Amaranthus retroflexus); the plants on the left are waterhemp (Amaranthus tuberculatus).
 
Unfortunately, the need to distinguish between these closely related weed species has become a reality for Manitoba producers and agronomists since waterhemp was found in the province in the fall of 2016.  Suspect plant specimen collected from a soybean field in the RM of Taché was verified as waterhemp by staff with the Agriculture and Agri-Food Canada Collection of Vascular plants in Ottawa.  Waterhemp occurs in neighbouring states and provinces, including Minnesota, North Dakota and Ontario.
 
Both species thrive in agricultural fields where they compete with crops for nutrients, moisture and light.  Waterhemp has no hairs on its stem or leaves, which can be used to distinguish it from redroot pigweed when plants are small.  The lack of hairs give waterhemp leaves a ‘glossy’ look unlike that of the ‘dull’ green leaves of redroot pigweed.  Also, waterhemp leaves are lanceolate in shape (longer than they are wide) compared to the more ovate leaves of redroot pigweed.  Colour is not a reliable identifying characteristic since both species can be green, red or variations of the two colours.
 
Mature waterhemp plants tend to be more branched than redroot pigweed.  And unlike redroot pigweed, which has male and female flowers on the same plant, waterhemp has separate male and female plants.  Waterhemp inflorescence are long, slender and vary in colour compared with the compact, prickly inflorescence of redroot pigweed.  Like most pigweeds, waterhemp is a prolific seed producer with up to a million seeds per plant (under ideal conditions).
 
Waterhemp populations resistant to group 2, group 9 (glyphosate) and group 2+9 exist throughout the US, including Minnesota and North Dakota, and in Ontario.  Seed from one of the plants found in Manitoba have been sent to Ontario for resistance testing.
 
Information on waterhemp will be added to Manitoba Agriculture’s weeds webpage and will be included at the Weed Seedling Identification Day (hosted by the Manitoba Weed Supervisors Association).  Manitoba Agriculture staff will conduct a waterhemp surveillance program in and around the RM of Taché in 2017.
 
Additional information on waterhemp is available at: www.extension.purdue.edu/extmedia/BP/gwc-13.pdf (excluding herbicide recommendations).

WEEDS: ANNUAL OR WINTER ANNUAL?

Fall is the most effective time to manage certain weed species.  The recommendations seem clear-cut:  winter annuals = fall herbicide application/tillage; annuals = no fall management.  But figuring out the life cycle of the weeds in your field this fall is the catch...
 
Bromes, cleavers, chickweed, night-flowering catchfly, narrow-leaved hawk’s-beard, shepherd’s-purse and stinkweed are all facultative winter annuals, meaning that they can germinate in either the fall or the spring depending on environmental conditions.  These weeds are often best managed in the fall, if populations warrant it.  In general, waiting until about this time of year maximizes fall-germinating flushes of winter annuals.  If using a herbicide, consider weed stage and the weather forecast, prior to application.
  
The problem is, given the right conditions – like the long falls and mild winters we’ve had the last few years –several of our annual weed species can also successfully overwinter:
 
Biennial wormwood – Despite its name, biennial wormwood behaves like an annual in agricultural fields.  When scouting, estimate the average growth stage of biennial wormwood populations in a field.  If the majority of the plants have already set seed, a fall herbicide application won’t help.  An application may be worthwhile only if there is a large flush of biennial wormwood that haven’t set seed and are less than ~3 inches tall.  Herbicide tank-mixes containing glyphosate + group 4 are more effective than glyphosate + group 2 on this weed.
 
Round-leaved mallow (RLM) – This annual weed can act as either a winter annual or a short-lived perennial, although it is more sensitive to freezing than our common winter annuals.  Mild winters in 2015 & 2016 provided the right conditions for RLM to overwinter, allowing it to become (even more) problematic in certain fields over the last few growing seasons.  Long range forecasters are predicting a harsh winter across the prairies this year, which should control RLM.  However, if you have little faith in forecasts and decide to apply a herbicide, glyphosate mixed with either Distinct or DyVel DSp has activity on this weed.
 
Stork’s bill – Like biennial wormwood, stork’s bill tends to be predominantly an annual in Manitoba.  If this is a problem weed for you, scout affected fields to determine average weed stage.  Again, if most of your stork’s bill has set seed you’re better off working on a plan for next year.  Stork’s bill, especially larger plants, is relatively tolerant of many herbicides.  If you decide to apply a herbicide because of stork’s bill this fall, glyphosate + group 2 or glyphosate + group 2 + group 4 on weeds up to the 4 to 6 leaf stage is probably your best bet.

Soil Fumigants

Soil fumigants are pesticides that form a gas when applied to soil. Due to the toxicity of soil fumigants and the potential for gases to move from the soil to the air, soil fumigants are classified as restricted use pesticides.

Prior to using soil fumigants read the entire product label. More information on the below requirements for use can be found on the product label.

Requirements for the use of soil fumigants include:
  • Soil fumigation licence: Soil fumigants are only to be used by individuals holding a soil fumigation licence. This restriction applies to all handlers of soil fumigants. Soil fumigation certification is currently not available in Manitoba. Users of soil fumigants are required to certify in Ontario and apply for a licence in Manitoba. More information on certification and licensing can be found below.
  • A Fumigation Management Plan (FMP) for all soil fumigation applications: A FMP must be developed prior to the start of any application. Instructions for the preparation of a FMP are required to be on the product label. To create a FMP follow label instructions or use the template found at: https://www.opep.ca/index.cfm/information/forms/ 
  • Mandatory Good Agricultural Practices (GAPs): GAPs improve the safety and efficacy of soil fumigation and must be followed during all fumigant applications. These application practices include monitoring of weather conditions, soil preparation, monitoring of soil temperature and moisture, and proper soil sealing.
  • Notification: The applicator must verbally warn workers of the application. Fumigant Application signs must be posted on all entrances to the application block.
  • Restrictions for workers re-entering treated areas: Only workers involved in soil fumigant application are allowed in the treated area following application. See label for duration of restriction.
  • Buffer zone: A buffer zone is an area established around the perimeter of the treated area where entry by anyone other than fumigant handlers is prohibited. A buffer zone must be established for every fumigant application. Buffer zone distances are based on factors such as application rate, area treated, and the application method. See product label for information on determining buffer zone distances.


Steps to obtaining a soil fumigation licence:

  1. Complete the Application for Pesticide Certification
    • The application form is available on the Ontario Pesticide Training and Certification (OPT&C) website under Exterminator Training: http://www.ontariopesticide.com/index.cfm/exterminator-training/
    • The application fee is $165 per person and includes the core manual, one module manual, and the examination.
    • A soil fumigation licence requires certification in Agriculture Core and Fumigation Soil. On the application form indicate that you are applying for certification in Fumigation – Soil.
    • Indicate the location and date of the exam under Examination Information:
      • Location: Carman, Manitoba
      • Date: June 29, 2016
  2. Read Agriculture Core and Fumigation Soil manuals
  3. Write the exam
    • The exam is scheduled for 9:00 - 11:30 am on June 29, 2016 at the MAFRD GO Centre in Carman, Manitoba (65 3rd Avenue NE, Carman, MB)
  4. Obtain general liability and pesticide drift insurance
    • Individuals applying for a Pesticide Applicator Licence are required to have general liability and pesticide drift insurance. Individual or company policies are acceptable.
  5. Apply for a licence
