Crop Report: Issue 14, August 6, 2013


Weekly Provincial Summary

  • Crop growth continues to be slowed by the cooler temperatures and the frequent rainfall in some areas of Manitoba. The moderate temperatures will benefit flowering and grain filling of many crop types. However, a return to warmer temperatures will help advance the warm season crops such as grain corn, soybeans, edible beans and sunflowers.
  • Winter wheat harvest has started in Manitoba with preliminary reports of yields ranging from 60 to 80 bushels per acre, with good quality and protein levels.


Southwest Region

Rainfall varied throughout the Southwest Region over the past week with accumulations of 10
to 50 mm. Temperatures remain cooler than normal. Moisture levels remain above normal and
there are still reports of overland flooding in some areas.
The cereal crops are progressing with most fields in the soft dough stage. Several fields are
starting to show disease pressure; fusarium head blight can be found in almost all wheat
fields and the severity varies according to variety and fungicide application. Net and spot
blotch are evident in some barley fields. Several crops are lodging because of recent wind
and rain events. In some cases the lodging is permanent.

Canola continues to flower with some of the earlier seeded crops going out of bloom. Cool,
moist conditions allow canola to flower for several weeks, increasing yield potential.
Sclerotina is evident in several fields in the Southwest Region, and as the crop matures
premature ripening will be more noticeable. Some producers in the south east part of the
region are reporting high numbers of armyworms where spraying may be needed.
Flax crops are benefiting from the cool, moist conditions and most of the crops have
completed flowering. Peas are done flowering and are producing lots of pods. Cool
temperatures slowed down the progress of corn, sunflower and soybean crops. The crops are
doing well with potential for high yields but most producers are starting to be concerned
about days to maturity.
Several producers have been silaging over the past week and cereal silage is yielding average
to above average. Most producers continue to hay and are having problems getting good quality
as the rain is resulting in weathering.
Pastures are rated as good. Dugouts are 90 to 100% full.

Northwest Region

Temperatures were moderate to below seasonal throughout the Northwest Region, with occasional
overnight lows of 6 to 8 degrees Celsius. A few light scattered rain showers affected the
Swan River area mid-week. Late in the week the Dauphin to Grandview areas had rain
accumulations of 17 mm with higher amounts in some localized areas. With the moderate drying
conditions, in most sectors 10 to 30% surplus moisture conditions still remain.
Crops continue to advance under below seasonal temperatures and generally adequate moisture
conditions. Overall, area crop yield potentials are better at Swan River Valley and the
southern sector from Roblin through Ste Rose. The Pas, Ethelbert and Fork River areas have
been more impacted by excess moisture through the growing season and the yield potentials are
only fair to poor.
Winter wheat is ripening with harvest anticipated shortly. Canola, oats and barley are rated
at 70 to 90% excellent. Canola acres are 50% fully podded, 20% is at full flower and the
remainder is at various stages of podding. With continued below average temperatures, corn
and soybeans are developing more slowly with 60 to 70% of acres rated fair to good. Up to 60%
of the soybean acres are at R3, with most of the remainder through the Ste. Rose area at R4
to R5. Perennial rye grass is being swathed.

Symptoms of fusarium head blight and sclerotinia is reported across the region. No reports of
bertha armyworm control were received from the moderate-rated risk area north west of Roblin
and parts of the Swan River Valley. Grasshopper activity is low and generally on lighter
pastures soils and ridges.
Haying conditions improved the past week. Overall, the tame forage acres are approximately
75% baled and 25% has been cut; generally, average yields are reported. Forage quality is
variable, rating from good to poor. The native hay harvest has begun in the accessible drier
fields. Through the Westlake area, 50 to 75% of the low lying native hay lands adjacent to
the lakes will have little potential for production because of wet and inaccessible fields.
Pastures are rated as fair to good in most areas. Dugout water levels are full in all areas.

Central Region

The Central Region saw cooler temperatures, along with scattered showers. Eastern parts of
the region report 15 to 25 mm of rain, while western areas received 20 to 40 mm. Field
conditions in most cases are good as crops are handling the frequent rainfall, with the
exception of a small percentage of acres where water is ponding.

Crop growth has slowed with the cooler temperatures; flowering period is extended in some
canola, flax and pea fields and is allowing for a longer grain fill period in these as well
as cereal crops. A return of warmer temperatures would be welcomed however to advance all
crops, particularly the corn and bean crops.
Cereal crops are in full head with most acres in the late milk to dough stages. The last of
the late seeded cereal crops received fungicide applications. Preharvest applications are
expected to start soon.
Cooler temperatures are pushing back winter wheat harvest timing, but a few winter wheat
fields have been harvested. Early reports indicate good quality with yields in the 60 to high
70 bushel per acre range, with good protein. Perennial ryegrass harvest has begun with no
yield reports to date.
Canola continues to flower, with cooler temperatures and rains extending the flowering
period. The earliest seeded fields are podded with flowering complete. A few early fields may
be swathed towards the end of the week or early next week. Fungicide applications for
sclerotinia management continue on the later seeded fields, where staging and moisture
conditions warrant. More blackleg leaf lesions were reported throughout the region, along
with some basal and stem cankers.
The majority of corn is at the tasselling and silking stage. Soybeans and edible beans are
flowering with podding and filling continuing. Ray flowers are visible in all sunflower
fields and most fields are in the R5.1 stage. Fields are being monitored for insects and
diseases. Some potato acres in the southern areas of the region have been top-killed and
harvest will soon start.
Bacterial blight is evident in most soybean fields and some edible bean fields, as is
sunburn. Root rots are evident in many soybean fields.
Some lodging is evident in cereal crops in areas of heavy rain and wind. Some of the crop has
recovered. Hail is probably more widespread than previously noted, with damage mostly
confined to leaf injury.
Late germinating wild oats are now evident in some winter wheat and spring wheat crops.
Redroot pigweed and kochia are also evident in canola and some cereal crops. Volunteer crops,
including canola, soybeans and corn, are becoming more noticeable.
Diamondback larvae are found in canola with no significant damage at this point. Higher
bertha armyworm trap counts are seen, with numbers in the low to uncertain risk range. Trap
counts are starting to decline. Grasshopper activity continues in much of the region,
although many areas report a decline in numbers. Evidence of the fungal infections that
attack grasshoppers has been noted. Numbers on headlands of many cereal, canola and hay
fields have warranted spraying, also roadsides and drains, as well as some entire fields,
with hot spots throughout the region. Clipping of bolls in flax fields has also warranted
control measures.
Showers and high humidity continue to make haying a challenge. First cut dairy hay is
complete and second continues. Baling of first cut beef quality hay is done with not much
progress on second cut, as producers wait for better weather conditions. Some concerns of cut
hay moulding in swath and general loss of quality. Average yields are expected for most
areas. Some silage is being done.
Most pastures are growing rapidly and are in good to excellent condition, although some still
suffer due adverse conditions, primarily excess moisture. Rainfall has been welcomed for
second cut and pasture regrowth on sandy soils. Dugouts are full.

Eastern Region


Rainfall amounts in the Eastern Region ranged from 5 to 16 mm this past week as a result of

spotty showers.
Crops in general are doing well. Winter wheat is ripening with harvest beginning, canola is
podded with bottom seeds beginning to change colour, cereal crops are in the dough stage,
soybeans are podded and the corn is at the tassel to silking stage. Sunflowers are flowering.
Concerns about grasshoppers, green cloverworm, armyworms and other defoliators continue in
cereal, canola and soybean fields. Canola concerns are moving from leaf damage to pod damage
issues. No soybean aphid reports to date; some diamondback larvae have been found and one
field above threshold was sprayed.
Root rots continue to be a problem in soybeans with lab reports indicating either fusarium
wilt or phytophthora root rot.
Haying continues in the Eastern Region. First cut is finishing up with progress at 5%
standing, 5% cut and 90% baled or silage. Second cut progress is rated at 65 to 80% standing,
5 to 10% cut and 10 to 30% baled/silage. First cut harvest of alfalfa and alfalfa/grass
fields for use as dairy feed is complete. Regrowth of these fields is looking good and a
second cut has begun. First cut harvest of alfalfa, alfalfa/grass and tame hay fields
intended for beef cattle feed is nearly complete. Harvest of native grasses is well underway
and roughly 80% complete. Average percent of normal yields for both first and second cut are
reported as: alfalfa 95%, grass/alfalfa 95%, other tame hay 95% and wild hay 75%.
Pasture conditions in the region are rated as 50 to 75% good, 25% fair and 0 to 25% poor in
the region. Livestock water supply is rated at 100% adequate.

Interlake Region

Precipitation amounts ranging from 4 to 30 mm was experienced last week throughout the
Interlake Region. Cool daytime temperatures delayed crop ripening in such crops as winter
wheat and other spring cereals.
Winter wheat harvest on select fields in North and South Interlake have started, although
most fields are still a week or two away from combining. Early reports indicate the yields
are less than expected but quality is good. Canola continues to ripen slowly with the chance
that some fields in South Interlake may be cut towards the end of the week. Throughout the
region, there are still canola fields flowering due to the cool, wet conditions. Spring
cereals are starting to turn color and corn is beginning to tassel. Most forage grass seeds
are cut and ready to combine later in the week if weather conditions allow.

Second cut hay began with reports of 0.5 to 1 ton per acre yield. Native hay is still being
cut and baled with yields ranging from 1 to 1.5 ton per acre. Pasture and dugout conditions
are good.
