Crop Report: Issue 16, August 14, 2017


Weekly Provincial Summary 

  • Warm weather has advanced crops, and also caused some injury in canola.
  • Rainfall occurred throughout the province, but more rainfall is needed in many areas.
  • Harvest has begun in winter cereals, spring cereals, and field peas. Canola is starting to be swathed.
  • Insect monitoring is on-going, but disease incidence remains low. 
  • Haying continues, but in dry areas re-growth is minimal and pasture quality is declining. 


Southwest Region

Rainfall amounts varied throughout region with larger amounts falling in isolated areas. The highest recorded was Shoal Lake with 77 mm. Most of the rain fell in the early part of the week, hot and dry weather for the remainder of the week allowed producers to resume harvesting activities.

Winter wheat and fall rye harvest continues with quality being average and yields slightly below average. Spring seeded cereal crops are close to desiccation. Some early seeded barley is harvested. Barley yielding close to long term averages, with good quality, and lower test weights.

Canola is starting to ripen and fields are being swathed. Spraying for Diamondback moth has pretty much stopped however producers are still spraying for Bertha Armyworm in some areas.

Pea harvest has started in some areas and yields are slightly above average with good quality.

Soybeans range from R4 to R5. There are reports of soybean aphids, but limited spraying has occurred.

Flax is at boll filling stage of development.

Sunflowers are in the R5.5 to R5.6 stage. Bird damage is reported in some fields in the South west corner of the region.

Corn is at the R2 to R3 stage.

Pastures have improved from the rain and this will help extend grazing for some producers. Second cut alfalfa has started in several areas that had enough regrowth to warrant a cut.

Dugouts have improved to about 70% full from recent rains. 


Northwest Region

High daytime temperatures have quickly advanced crops throughout the region. Localized rain early in the week will help contribute to crop yield in later and warm season crops. Rainfall amounts ranged from 6 to 28 mm in the Swan Valley; 11 to 22 mm in the Dauphin/Ste. Rose area with McCreary receiving 35 mm.  

Some pre-harvest applications have begun across the region as crops ripen and conditions allow. Heavier crops have lodged from previous heavy rains/high winds and will pose a challenge at harvest. Swathing of canola has been reported in the Dauphin region, as well as combining of winter wheat and early seeded barley.
The majority of spring wheat is in the dough stage, with the remainder at milk. Approximately 90% of the canola is podded with 50% reaching the ripe stage in the Roblin area. Soybeans are podding. Pea and lentils crops have ripened and pea harvest is underway in the Swan Valley. About 50% of the flax in the Roblin area has reached the boll stage.


With the drier conditions this year and more native hay being accessible, native hay harvest is continuing. Second cut alfalfa is also being put up with yields varying from poor to good. The Pine River area is still struggling with hay harvest due to excess moisture. Cereal silage and greenfeed harvest has begun with further progress made in the Dauphin area. Pastures are holding up and those that received rain last week are in better condition. Additional rain would further benefit pastures in the region. 


Central Region

High daytime temperatures continued and rain was variable throughout the region with most areas receiving less than 10 mm. Some crops are ripening prematurely due to lack of rain, especially in areas with gravel and sand ridges, and areas with salinity.
Harvest continues in fall rye and winter wheat; fall rye is yielding 75 to 110 bu/acre and winter wheat 50 to 80 bu/acre. Quality and test weight is good. Lower yields are due to winter injury.
The latest spring seeded cereal fields are at the end of milk stage. Harvest started in spring wheat, barley, and oat. Barley yields are ranging from 80 to 110 bu/acre, with excellent quality. Oat yields range from 130 to 170 bu/acre, with good test weight.
Early seed colour change is evident in later seeded canola fields. Swathing continues, as do desiccation applications for straight cut canola. Sunscald is making crops look riper than they are. Some heat blasting is evident in mid-late planted canola. Some blackleg and sclerotinia is evident. Both crucifer and striped flea beetles can be found feeding on green leaves and pods, with minimal impact. Scouting continues for Bertha armyworm and Diamondback moth with a few fields in the western parts of the region near or at threshold with some spraying reported. Most Diamondback moths are now in the cocoon stage, past damaging the crop.
Peas are standing well. Harvest continues, with yields ranging from 50 to 80 bu/acre. Flax fields are in full boll and starting to turn.
Soybeans are in the R4 to R6 stage. Some soybeans are at R7 on knolls and ridges and are drying out, not turning. Dry conditions resulted in some upper pods not filling. Root rots are reported with rhizoctonia, fusarium root rot, pythium, and phytophthera. Monitoring for soybean aphids continues with some control required due to populations above economic thresholds. Spider mites and white mould have been found.
Early types of edible beans are seeing some leaf drop as a result of drier conditions. White mould is being found in dense canopy areas; control measures aren’t economic at this late stage.
Most sunflowers are at later stages of flowering; R5.5 to R6 and early ray flower drop. Some basal stalk rot is evident.
Most corn is in the grain filling stage; ranging from blister to milk.
Late blight has been detected in potatoes. Producers continue to spray to prevent infection.
Grasshoppers are being found in fields, especially in drier areas. Monitoring continues, and some control measures have been taken where crop injury warrants.
Forage seed crops are being swathed, and harvest continues. Stands look good, and average to above average yields are expected.
Second cut hay is being harvested but yields are down due to dry conditions. First cut was slightly below average. Wild hay harvest continues. Second cut dairy quality hay continues in areas of early first cut and where re-growth is adequate. Second cut beef quality hay in some western and southwestern areas is non-existent due to poor rainfall and limited regrowth.
Pastures are dry and turning brown. Rain is needed to sustain pastures and livestock into the fall; supplemental feeding may be required earlier this year.
Livestock water supply is adequate, but some rain would benefit dugout levels.  


Eastern Region

Rainfall accumulation across the region ranged from 3 to 35 mm. There was very little evidence of standing water after the rainfall. Isolated reports of drought symptoms on soybeans and corn on lighter textured soils were received before the rainfall occurred. Crop development continues at a good pace and overall condition varies from good to excellent. Soil moisture conditions on cropland across the region and are rated as 80% adequate and 20% short with the driest soil conditions occurring in southern districts. Soil moisture conditions on hay and pasture land are rated at 60% adequate, 20% short and 20% very short with the driest soil conditions occurring in southern districts.

Cereals are at the hard dough/ripe stage and are in good to excellent condition. Pre-harvest applications are almost complete. A few fields of early seeded oats and wheat have been harvested. No yield reports as of yet. Corn is at the tassel/silking to blister stage. Some fields could benefit from additional rainfall.
In canola pre-harvest applications and swathing have started. Some late seeded fields are at pod filling. Soybeans are in the mid to late R5 stage with some fields in R6. Monitoring continues for soybean aphid, some fields have been sprayed. 
Sunflowers are in late R5 to R6. Low disease and insect pest levels continue.
Haying continues as pastures are starting to dry up. Some producers are feeding hay or moving cattle to where re-growth is good. Greenfeed silage cut with above average yields. 
First cut alfalfa yield estimates are 1.5 tonnes/acre, 2 tonnes/acre for grass/alfalfa mixes, 1.75 tonnes/acre for tame hay, and 1 tonne/acre for wild hay. The progress of the first cut of hay is estimated at 20% standing, 5% cut and 75% baled /silaged. Second cut alfalfa hay is estimated at 1.5 tonnes/acre with grass/alfalfa hay at 1.25 tonnes/acre. Hay quality is rated as good. Hay field condition was rated at 80% good and 20% fair. Pasture conditions was rated at 50% good, 20% fair and 20% poor and 10% very poor condition. The availability of livestock water is rated as adequate to short with 25 to 30% remaining in dugouts. 


Interlake Region

Crops continue to advance quickly with the high daytime temperatures. Rainfall throughout the region varied from 2 to 30 mm.  

Winter wheat and fall rye are being harvested and show very low incidence of ergot. Winter wheat yields low, as winterkill resulted in poor stands. Fall rye yields are average to good.
Spring cereals fields are turning with some preharvest applications on spring wheat. Most of the barley has been harvested with yields in the 80 to 100 bu/acre range and good quality reported. Fusarium head blight is evident but at very low levels. 
Canola in most south Interlake fields has some seed colour change and swathing and pre-harvest applications have started. Flowering in later seeded north Interlake fields is complete. Sunscald makes the crop look more advanced than they are. High temperatures have caused flower abortions in late seeded fields. Diamondback moths are in the cocoon stage; for the most part past the damaging larva stage. 
Soybeans are R3 to R5. Soybeans are being monitored for aphids, and some fields have been sprayed. Approximately 15% of the soybean acres in the north Interlake have been sprayed for soybean aphids. Spider mites have been found at low levels. 
Corn in south Interlake is silking and cobs are forming. Flax bolls are turning brown, and straw is starting to turn. Field peas are being harvested, some yielding 70 to 80 bushel/acre.
Grass seed harvest continues. Tall fescue and meadow fescue harvest is complete. Timothy yields are average, 350 to 500 pound/acre. Perennial ryegrass is being swathed and some combined; yielding 600 to 700 pounds/acre. Reed canary seed yields have been poor due to dryer conditions than that crop prefers. Alfalfa seed crop monitoring for insects continues.
Haying continues, grasshoppers have been slowing up at low levels with limited damage. Cereals and cereal/pea mixtures are being ensiled and yields are average to good; in the 5 to 8 ton/acre range.
Pastures are in good to fair condition. Well managed pastures are showing their late season resilience. Grass in areas in continuous hard grazed pastures are going dormant. Dugouts are 50 to 80% full.
