Tips to Marketing Downgraded Crops

Over the past few weeks, we’ve heard about the impact of the poor weather conditions over the harvest period on the quality of harvested grain.  With the crop off the field and into the bin, marketing now becomes the focus of many producers.

In the attached article (updated from 2014) by Gary Smart, Farm Management Specialist with Manitoba Agriculture, he provides excellent information to cope with downgraded crops.  Some highlights include:

  • When marketing poor quality grain, be prepared and don’t panic, especially right at harvest time.
  • Know the quality and find a buyer who will offer the best value.
  • Take good samples. Without thorough samples, it is tough to know what is actually in the bin.
  • Communicate with the buyer if already some of this year’s crop is already contracted.
  • Unless cash flow is an issue on the farm, being patient could be the best action to take as new markets may arise for poor quality grain.

It’s That Time of Year – Talking Fall Frosts in Manitoba

UPDATED FROM ARCHIVED CROP CHATTER POST MADE AUGUST 15, 2013

As we enter in the later parts of the growing season, fall frost enters the minds of most people involved in the grain industry.  As everyone knows, frost can have an impact on a crop’s quality and yield.  There were a few areas reporting a light frost event the morning of September 14th.

The extent of frost damage to a crop will depend on several factors. The species, stage, and hardening of the crop, the soil type and soil moisture, the actual air temperature, the duration of freezing, and the rapidity with which freezing takes place are all important. A drop in air temperature of short duration will cause less damage than a prolonged periodthe same low temperature. When the air temperature drops to 0°C, cereal and other crops may not sustain damage. Rather, damage or total loss is more common when minimum temperatures drop below -2°C, often referred to as a killing frost.

Given its sporadic nature, long-range forecasting of frost is nearly impossible. Rather, the climate record of an area is used to determine probable dates of frost based on long-term temperature records. While this will not provide an actual frost date in a particular year, it will present the likelihood that frost may occur on a certain date. This can be a valuable planning tool.

The Manitoba Ag-Weather Program released updated FIRST FALL FROST MAPS in 2014 which are made from the new township gridded normal from a wider dataset of 1950-2010:

So we had a Frost on our Soybean, Now what?

The first step in accessing frost damage is asking how cold it was last night. A light frost of -1°C for short durations may clip off a few off the top leaves with no effect on yield. The concern begins when a killing frost at least -2°C occurs for an extended period of time. In this situation you will see frozen leaves and pods throughout the canopy.  This may cause quality issues and yield reduction if the crop has not reached full maturity.

See the latest MB Ag Weather latest frost map: http://www.gov.mb.ca/agriculture/weather/pubs/minimum-air-temperature.pdf

What growth stage are your beans at, see http://www.manitobapulse.ca/soybean-staging-guide/ as a reference.

A killing frost at the R8 growth stage will see no yield or quality loss. The R8 stage is when the leaves have dropped off, all pods are brown, and seeds rattle within the pods when plants are shaken.

If however your beans are at the R7 growth stage, (which means one pod on the plant has reached its mature color), research has shown yield loss can range from 5-10 % dependent upon the severity of the frost. Quality issues in the way of green seed may also occur.

Finally, if your beans are at the R6 growth stage-(this is where pods containing a green seed that fills the pod cavity at one of the four uppermost nodes on main stem), yield losses can range from 20-30 %.  You will also have green seed issues which can also lead to marketing concerns.

There are a few areas in Manitoba where the beans are at the end of this R6 growth stage.  Most of the beans in Manitoba are at the R7-R8 growth stage. A light frost should not affect yield and quality for these beans. If beans were at the R6 growth stage and a hard frost occurred yield and quality losses would be noticeable.

The Canadian Crop Hail Report – Release Date of August 11th

The Canadian Crop Hail Association represents the companies that sell crop hail insurance to producers in Western Canada. The Hail Report is released every second Thursday during the hail season to provide information on storms, claims and related issues. The report is compiled by McArton & Associates Communications at Dilke, Saskatchewan.

The following is the report for Manitoba from the August 11th Report:

Hail claims in Manitoba remain above the five-year average. A July 20 storm that moved in from the US through Darlingford and Thornhill saw some areas reporting hail that lasted for periods as long as 45 minutes, resulting in severe crop damage. That storm continued north-west towards Manitou and Pilot Mound, lessening in severity as it continued on to the Holland and Treherne areas. On that same day, a storm travelling east from Saskatchewan caused significant damage in areas around Hamiota and Minnedosa. Hail activity in the province has slowed dramatically since those events.

Storm dates and locations of significance for this period included:

  • July 19: Cardale, Darlingford, Hamiota, Holland, Minnedosa, Morden, Neepawa, Notre Dame De Lourdes, Rapid City, Solsgirth, Somerset, Strathclair, Swan Lake, Treherne
  • July 20: Brandon, Dunrea, Elgin, Haywood, Holland, Justice, Killarney, Melita, Minnedosa, Neepawa, Reston, Rossendale, Sinclair, Somerset, St. Claude, Waskada, Winkler
  • July 30: Minto
  • August 1: Hamiota
  • August 3: Souris

HERBICIDE OPTIONS FOR PRE-HARVEST MANAGEMENT – KNOW THE DIFFERENCES!

Harvest 2016 is here as winter wheat and fall rye harvest has started in some areas of Manitoba. With favourable weather, crops are advancing quickly so now is a good time for a refresher on pre-harvest management!

As agronomists and producers, there are a few distinctions you need to be aware of between the pre-harvest herbicide products that are available for pre-harvest management. When done correctly, a pre-harvest application can provide a number of benefits including maximizing yield and quality, allow for direct combining of standing crops, perennial weed control and managing weed escapes from the growing season, and can speed up harvest timing.

However, it is critical to know the differences between the herbicide options to manage product expectations, and to ensure application is done correctly to make your crop export ready! The following are some key points to remember when considering your pre-harvest management.

  • The most commonly used active ingredients used for pre-harvest management are glyphosate, diquat (ex. Reglone), saflufenacil (ex. Heat), carfentrazone (ex. Aim) and flumioxazin (ex. Valtera). There are also products that are pre-packaged mixes of active ingredients (ex. CleanStart with glyphosate and carfentrazone).
  • Products such as Reglone or Heat are desiccants. GLYPHOSATE IS NOT A DESICCANT. Desiccants and glyphosate work very differently, usually require different application timings and parameters, and provide different benefits.
  • Desiccants that contain diquat (e.g. Reglone, etc.) have been registered the longest in many crops and are the gold standard to which all other desiccants are compared. Diquat rapidly dries down green plant material, with desiccation typically occurring within hours to a few days. In fact, diquat fast acting nature sometimes works against itself, by limiting uptake by drying plant material, which is why the labels recommends applying these products at dusk or on cloudy days.
  • Newer desiccants, such as Aim, Heat and Valtera, also result in the dry down of green plant material. Research has shown that Heat and Valtera are often just as or more effective than diquat for desiccating crops, and usually only take slightly longer to do so. Aim, on the other hand, is relatively slow acting, which makes it an ideal partner for glyphosate. And research has shown a synergistic effect when Aim and glyphosate are tank mixed (i.e. CleanStart), something not seen with other desiccants. Opposite to diquat, these desiccants are best applied on sunny, warm days.
  • Coverage is important for these contact products, so be sure to keep water volumes up!
  • GLYPHOSATE IS NOT A DESICCANT but can enhance dry down of crops. Research has shown that, compared with untreated crop, glyphosate can improve crop dry down after 7 to 14 days (depending on the weather). But glyphosate typically does not dry down crops as consistently or to the same extent as the true desiccants.
  • However, glyphosate is a popular pre-harvest choice for many growers since, as the only systemic, is provides control/suppression of weeds, including winter annuals and perennials. Desiccants will also dry down green weeds, but only provide top growth control.
  • Proper application timing is critical regardless of the product used. Always refer to and follow the product label for the correct timing and rates. Remember, desiccants or glyphosate neither bring about nor speed up crop maturity. However, it can decrease the time between when the crop has reached maturity and when the crop is harvested.
  • Proper application timing is especially important for glyphosate. When applied too early, glyphosate residues could accumulate in the grain and may exceed Maximum Residue Limits (MRLs) of important export countries.
  • Residues for the contact products (diquat, Aim, Heat and Valtera) are usually very low because of their contact nature. But that doesn’t mean that these products are without MRL concerns since, in many cases, residues tolerances can be exceeded simply because an MRL has not been established in all markets.
  • Cereals Canada, Canola Council of Canada and Pulse Canada have information available through their “Keep it Clean” initiatives. Please refer to the following websites for additional information for meeting export standards, why MRLs matter, pre-harvest interval information, and herbicides that should not be used.

Manitoba Insect & Disease Update – Issue 10: July 20, 2016

The Manitoba Insect and Disease Update is now posted at: http://www.gov.mb.ca/agriculture/crops/seasonal-reports/insect-report-archive/insect-report-2016-07-20.html

Some highlights from the update:

Insects:

  • Pea aphid levels are still a concern in some pea fields, although many fields will be getting to the stage where management would no longer be economical.
  • Aphid levels have dropped in many cereal fields where previously levels had been increasing. High levels of natural enemies have been noted in some of these fields, and some intense rains may have also contributed.
  • In some areas of Central and Southwest Manitoba, greater than 90% of the wheat midge are expected to have emerged. In many areas of Manitoba about 50 to 90% of wheat midge are expected to have emerged. A reminder that wheat that has already produced anthers is no longer susceptible to feeding by wheat midge. Even if adults are still active in these more advanced fields, the larvae will not feed on the grain.
  • Egg masses of European corn corer are starting to be noted in some fields of corn. So far there are no reports of high levels, but now is the time to be checking fields for the egg masses.

Plant Pathogens:

  • Some infections of blackleg in canola and fusarium head blight in cereals have been reported.
  • A few cases of loose smut in barley were also reported.
  • Two positive identifications of Goss’s Wilt in corn were made. The positive identifications were made based on immunostrips and/or polymerase chain reaction (PCR) assays.

HOW DO I CONTROL VOLUNTEER CANOLA IN MY SOYBEAN?

First ask yourself if you need to control the volunteer canola in your crop.  Research by Dr. Rob Gulden and graduate student Paul Gregoire at the University of Manitoba (U of M) showed that volunteer canola had little impact on soybean yield when there are less than:

  • 3 plants/m2 in solid seeded or narrow row soybean, or
  • 1.5 plants/m2 in wide row soybean.

Although economic thresholds (ET) such as these don’t consider seed return, this is generally not a concern for canola given it’s prevalence in our crop rotations.

If your volunteer canola populations exceed the ET, the U of M researchers also assessed the effectiveness of various post-emergent herbicides (Table 1).  Control of volunteer canola by the herbicides listed in table 1 are based on comparisons of treated research plots.  It’s unlikely that any of these options will provide full control of bolting or flowering volunteer canola.

Table 1: Ranking and application timing of volunteer canola herbicides in soybean

Vol Canola Control in Soybeans

*Will not control CLEARFIELD canola volunteers

**Registered in the Red River Valley only

Another consideration: use of these herbicides on larger volunteer canola may only set plants back, resulting in later flowering canola that may cause issues during soybean harvest.

Previous research by Dr. Gulden has shown that one of the best ways to manage volunteer canola is by limiting weed seedbank additions from canola harvest losses. Slower combine speeds while harvesting this year’s canola is a good way to reduce volunteer canola populations in future soybean stands.
