Crop Report: Issue 8, June 24, 2013


Weekly Provincial Summary

  • Many areas of Manitoba received significant amounts of rainfall over the past several days.  Impact to crops is being assessed and will depend on the stage of crop development and duration of the excessive moisture conditions.
  • Earlier in the week, crops showed rapid development given the warmer weather conditions.
  • Producers made excellent progress with herbicide applications; progress by crop type ranges from 80 to 100% complete.
  • First cut haying operations continue with average yields. 


Southwest Region

The Southwest Region experienced moderate to heavy rainfall over last week with amounts ranging from 30 to 200 mm.  The heaviest amounts fell in the Pipestone and Reston area where some localized overland flooding was experienced. Much of the remainder of the region received 50 to 80 mm with the area south of number #2 Highway seeing saturated soils and a larger percentage of fields experiencing localized flooding and standing water. Areas north of number #2 Highway, and in particular north of #1 Highway, were able to absorb the rainfall with only minimal standing water.
Weed control spraying operations continued with significant progress made early last week as several calm days allowed for day long spraying. Weed control measures in spring wheat are 90% complete, field peas 100%, malt barley 95%, flax and oats 75 to 80% and Liberty canola 90% complete. First pass glyphosate applications on canola, corn and soybeans are estimated to be 90% complete with second passes now 50% complete.
Insect activity continued to intensify early last week with flea beetle feeding in canola still requiring additional control measures to be taken. Cutworm injury also increased over the past week with most reports of activity coming from northern areas of Birtle, Rossburn, Strathclair, Hamiota and Elphinstone where control measures were taken. Recent rains will help reduce flea beetle pressure.
Winter wheat and fall rye benefited from recent rains and cooler temperatures. Fall rye is now heading and winter wheat is in the shot blade stage of development with some fungicide application starting.
Pasture and hay growth continued to improve over the past week with most forages now entering the reproductive stages of development. Initial yield estimates of first cut alfalfa stands improved from last week, ranging from 80 to 85% of normal in northern portions of the region and 90 to 95% of normal in southern regions. Water levels in sloughs and dugouts are now 90 to 95% of capacity in northern areas and 95 to 100% in southern areas.

Northwest Region

Variable weather conditions continued through the week in the Northwest Region with periods of higher winds, at or below seasonal temperatures, and scattered thundershowers. By the week’s end, all areas of the region were affected by rains and heavy thunderstorms with precipitation amounts from 75 to 125 mm. Producers in the Westlake area from Eddystone to Meadow  to Portage report receiving up to 190 mm of rain. In the more affected sectors, flooding and some damage to infrastructure and roads is limiting access to livestock, pasture and fields.
Crop development, stand consistency and crop conditions have been good. Cereals are rated to 80% as excellent to good; canola at 75% good to excellent. Cereals crop development are 10% at stem elongation and 75% at tillering stages; canola at 55% rosette, and 45% seedling; and 65% of the soybeans are at 2 to 3 trifoliate staging.  Crop staging is variable by area within the region; most advanced crop development is seen through Roblin and Russell areas and is less advanced through Winnipegosis and McCreary.  At The Pas, crops are beginning to yellow from the excessive moisture received over the last two weeks. With the recent rainfall, some localized water ponding in crops, forages and pastures is now evident in all areas of the region and particularly in the low-lying areas. Soil moisture conditions are now rated as adequate to surplus. The Pas and Westlake areas are in surplus condition.
Herbicide applications continued between some difficult weather conditions and is 85% completed overall. Efficacy on weeds generally has been very good, although some additional applications were required due to timing and rate issues. Left for completion of weed control applications are the late seeded acres through pockets within the region.
Canola insect trap counts continue to be very low. Low numbers of European Skipper larvae were observed in a few mixed hay fields.
Condition of forage and pasture land are rated as good to fair; yields are expected to be average or below average. Moisture supply is adequate to surplus and some warmer temperatures are needed to increase grass yields. Hay harvest is very limited to date; some initial cuts just before the rain were not baled and remain in the wet field conditions.  Pastures and native hay lands in the Westlake sector are wet, particularly on low-lying lands near the lakes. Dugout water levels are full to adequate.

Central Region

Warmer temperatures were very welcome for crop growth in the Central Region.  Rain fell throughout the region with some areas receiving significant amounts over the weekend. Altona area 12 to 20 mm, Morris area 18 to 38 mm, Portage area 20 to 40 mm, Carman-Elm Creek  15 mm, Starbuck 40 mm, Headingley 10 to 125 mm, St. Francois Xavier  75 to 90 mm, Mather/Cartwright  100mm, Gladstone  75 to 90 mm, Plumas 65 to 75 mm, Woodside 50 to 60 mm and pea sized hail, Westbourne 125 mm, with an area to the south reporting 250 mm.  Areas with the heaviest rainfall saw localized flooding.  Standing water in areas with higher rainfall is a concern and crops will be assessed; damage is expected due to the excess moisture.  Some acres remain unseeded due to excess moisture.  Some of these acres will see forage seed and greenfeed planted.
Windy conditions interfered with and delayed herbicide applications, but good progress was made this past week. 
Growth of most crops is improving although stands of many crops are uneven. Some canola was reseeded due to poor crop stands, further compromised by heavy flea beetle pressure.  Crusting was an issue on some fields following heavy rains, with reseeding required for some crops, including soybeans and canola.
Cereal crops are in the seedling and tillering stages, with the most advanced fields close to flag leaf.  Spraying continues in the latest-seeded fields.  Leaf diseases are evident, especially in fields with cereal stubble from the previous year.
Corn crops are improving in colour and growth has improved greatly. Soybeans range from unifoliate through to early third trifoliate stage.  Most fields have had one application of glyphosate. Growth was slow, particularly for the earlier seeded soybeans; fields planted in late May emerged much more rapidly. 
Canola ranges from just emerging to bolting and early flower. Most fields received a first herbicide application, and many received a second application.  Flea beetle feeding was a concern in much of the region.  Some fields were sprayed three times due to heavy feeding pressure and fields are being monitored closely.  Reseeded fields are looking good.  Flea beetle feeding has declined in many areas, but activity is still evident and a problem in some fields. Earliest seeded fields had the most pressure; some fields seem to be bolting early due to combined stresses.
Fall rye is headed and winter wheat is entering the flag leaf to early heading stage; fungicide applications continue.  Most fields have variable crop staging and timing for fusarium head blight suppression fungicide application, if necessary, will be difficult.
Cutworms are reported in a few corn and broadleaf crops.  Some insecticide application was required.   Diamondback moth monitoring continues.  Trap counts are highest in eastern parts of the region.  Bertha armyworm trap counts are low.
Haying continues with average yields expected for most areas.  Gladstone area reports some alfalfa reseeded due to grasshopper damage.  Beef quality alfalfa cutting will begin shortly. Hay fields were slow to progress with average to cooler temperatures but growth is improving.  Grasses in pastures are starting to head out.  Most pastures are growing rapidly, although some still suffer due to adverse conditions.  Dugouts are full. 

Eastern Region

Rainfall amounts from 12 to 25 mm fell this past weekend in the Eastern Region. Crop land moisture levels across the region are rated at 90% adequate and 10% short. 
Crops in general appear to be doing well across the Eastern region as all crops showed rapid development last week given the more favourable weather conditions.  Crop stages are as follows: winter wheat is heading out, canola canopy is closing and is just starting to bolt/flower, cereal crops at stem elongation, soybeans are at the 2 to 3 trifoliate stage and corn has 6 to 7 leaves.
First pass or single pass herbicide applications are 90 to 95% complete.  Mainly canola acres are left and producers will assess if a second herbicide pass is required on soybeans.  The second herbicide application on corn acres requiring it is occurring.  Herbicide performance in general has been satisfactory with no major concerns.  Foliar fungicide on winter wheat is complete and spraying for fusarium head blight will start as soon as the plants start to flower.  Foliar fungicide applications on annual cereals could start by weekend.
Leafhoppers are being reported in some soybean fields but no defoliation is evident.  Some lygus bugs were also found but no concerns to date.  Regrowth continues in soybean fields impacted by hail.  In cereal fields, root rots and wireworms are impacting stands.  Effects of the cool spring, particularly on crop planted without a seed treatment, is still evident. 
Hay conditions in the region are rated as 80% good, 15% fair and 5% poor. Haying continues with progress varying from 20 to 80% standing, to 5 to 80% baled.  Alfalfa yields are 95% of normal, grass/alfalfa 95% of normal, other tame hay 90% and wild hay 90%.   Earlier cut and harvested fields have good regrowth.  Pasture conditions in the region are rated as 50 to 85% good, 15 to 25% fair and 0 to 25% poor in the region.
Topsoil moisture on the majority of hay and pasture lands in the Eastern Region is rated as 80% adequate and 20% short.  Livestock water, including dugouts, is rated at 100% adequate.

Interlake Region

Isolated thundershowers through the week brought accumulations of 20 to 40 mm to some localized areas across the Interlake Region.  Moosehorn to Gypsumville were the hardest hit with water ponding in most fields.  General showers on Sunday accumulated to 20 mm across the region.  The Woodlands area received 45 mm from this system.  Warm, sunny conditions prevailed allowing for good growing conditions and rainfall was welcome across most of the region.
Herbicide application continues on annual crops.  Showers encouraged weed emergence in drier areas making additional herbicide applications necessary for some producers.  Winter wheat is beginning to head out.  Fungicide applications may be necessary depending on weather conditions and fusarium head blight risk. 
Alfalfa is in early bloom stage.  Seed producers are staging the crop for insecticide application prior to leaf cutter bee turn out.  Timothy seed fields are at the early heading stage.
First cut haying operations continue with generally good yields.  Older hay stands are providing less than expected growth for this time of year.  Recent rains should help to improve hay yield on these fields. Pasture conditions are average but will improve with recent rains.  No concerns with pastures or water supplies at this time.
