Crop Report: Issue 11, July 14, 2014


Weekly Provincial Summary

  • Favourable weather conditions in some areas of Manitoba are advancing crops, as well as allowing crops impacted by excess moisture to continue their recovery. However, continuing wet and flooded conditions in other areas of Manitoba continue to impact crop stands and yield potential.
  • Generally, the early seeded crops are rated in better condition than the late seeded crops, although impacts of excess moisture are also evident in early seeded fields. As fields continue to dry, the impact of the excessive moisture to crop stands become more evident.
  • Producers are assessing crop stands and yield potentials to justify further input costs in some fields.
  • Rainfall, high humidity and excessive moisture and flooding continue to impact first cut haying operations, although producers in some areas were able to make progress.


The Southwest Region experienced rain showers with severe thunderstorm, with precipitation amounts ranging from 5 to 30 mm. There was also isolated hail storms reported.
The extreme southwest areas of the region remain very wet, as well as land near the Assiniboine River.  In other areas of the region, favourable weather conditions over the past seven to ten days are allowing crops to recover. Crop losses due to flooding and standing water are still being assessed. Weed control measures resumed; most producers have completed weed control applications.
Canola is flowering and fungicide spraying is being done on most fields due to high risk of sclerotinia infection. Some late seeded canola fields are severely impacted by moisture and are flowering prematurely. Spring wheat is in the flag leaf to heading stages. Most producers are considering spraying for fusarium head blight. The soybean crop is handling the moisture very well. Most early seeded soybeans are starting to flower. Peas are starting to flower as well and are showing the effects of wet conditions as disease is impacting most low lying areas. Winter wheat and fall rye are in good condition with some reports of lodging due to high winds. Insect pressure is low. Bertha armyworm counts are below the economic threshold level in the region.
Limited haying has occurred and is being hampered by the wet conditions. However, haying is progressing in the more eastern and northern areas of the region. Reduced yields and little to no native hay harvest is expected to result in a forage shortage throughout much of the region. Producers are actively securing feed supplies for the upcoming winter. Pastures are rated from poor to good condition. Livestock producers impacted by excessive moisture are moving livestock to drier areas. The Virden area reports pasture lost to flooding is in the range of 20 to 30%.   


Warmer temperatures through the week and windy conditions over the weekend have helped dry fields. However, intermittent thunderstorms in the Parkland area resulted in limited drying progress. Crops that were sitting in water for prolonged periods, and those in low lying areas, are still showing the effects of excess moisture. Canola appears more impacted by the excessive moisture than wheat.
Canola growth is variable with 20% of the crop at seedling stage, 50% rosette and 30% flowering. Spring wheat development ranges from 10% emerging, 20% tillering, 40% stem elongation and 30% heading/flowering. Soybeans are in the vegetative stage while 75% of field pea acres are in the flowering stage. Corn in the region is generally rated as poor. Seeding of greenfeed continues where field conditions allow.
Some fungicide applications have been made. Producers were also able to spray some unseeded fields in an effort to reduce and remove weed growth.
There was some haying progress made in the region, while most areas still face wet conditions. However, the weekend rains halted progress. Yields are estimated to be average to above average, although in the Swan Valley area below average yields and quality are reported. Pasture growth is very good with the improved warm conditions and excess moisture. All dugouts and water tributaries are full. 


The Central Region saw variable temperatures; warmer days with high humidity allowed for good growth in many crops. Rainfall accumulations varied greatly due to thunderstorm activity. Most of the region received at least 10 to 15 mm with accumulations early in the week and over the weekend. Thunderstorms accounted for higher rainfall amounts in scattered areas. A hail storm hit the area from east of Crystal City through Manitou to Kaleida (along the US border) over a week ago. Crop damage assessments are continuing; some fields were severely impacted.
Crop conditions vary across the region as some areas have not received as much rain. A few areas with lighter soils would benefit from some rain. Other areas are showing extreme excess moisture stress, particularly the broadleaf crops, although cereal crops are affected also. Standing water in fields is still evident throughout the region. In general, early seeded crops of all types are faring better than late seeded crops, although drowned out spots are also evident in early seeded fields. Damage to crops by the excessive moisture becomes more evident as time goes on.
The late seeded cereal crops are at flag leaf to early head emergence. The most advanced spring cereals are finished flowering. Late seeded canola is bolting and flowering early due to excess moisture stress. Blackleg lesions are evident on leaves in many canola fields. Soybeans are flowering, with most fields in the R1 to R2 stage. Most fields are exhibiting some yellowing or iron chlorosis, although many fields are starting to green up with warmer weather and nodulation. Edible beans are also showing iron chlorosis. Corn is variable with most advanced fields up to 14 leaf stage. Many fields are suffering due to excess moisture though, and herbicide application is a struggle due to wet field conditions. Some fields will not see herbicide treatments as crops grow beyond the application window. Warmer temperatures have improved growth in corn, soybeans and edible beans.
Herbicide applications continue in all crop types as field conditions allow. Areas that are the wettest, and with later seeded crops are struggling to complete applications; some fields may not be sprayed. Weeds are growing rapidly, and rains, field conditions and winds are making these operations a challenge. Rutting is evident in the wettest fields. Soybeans continue to receive second applications, and edible beans and sunflowers are being sprayed as conditions allow.
Fungicide applications wrapped up in many cereal fields; this week will see most applications completed. Fungicide applications for sclerotinia in canola continue, although the majority of the acres are complete. Many later seeded canola fields will not receive fungicide treatment as the crop’s yield potential doesn’t warrant treatment. Fungicide spraying will soon start in edible bean fields as flowering begins.  The majority of acres receiving fungicide treatments have been completed by aerial application due to saturated field conditions, although ground rigs were busy later in the week.
Diamondback moth monitoring is complete; overall numbers are low. Larval feeding activity was seen, but minimal. Monitoring has begun for bertha armyworm moths. Numbers are low to date. Cereal leaf beetle larvae were found in several fields, at low levels not requiring treatment. Wheat fields are being monitored for wheat midge. Sunflower fields are being scouted for sunflower beetle activity, with no reports to date of numbers sufficient to require insecticide. Headlands and roadsides were treated for grasshoppers where numbers are the highest, also some fields. Continued rainfall and wet conditions may lower impact.
First cut haying continues as conditions allow, with some acres beginning second cut in the Morden and Winkler areas. Further west and north in the region, haying is occurring where possible. Yield reports vary, ranging from 1.5 to 4 bales per acre. High water, excess moisture and flooded acres are limiting factors. Hot dry conditions would be helpful to possibly salvage crop in the Portage, Gladstone and Woodside areas. There are concerns of a hay shortage.  Lake Manitoba levels continue to rise, and along with strong north winds, high water levels will compromise additional forage acres, as well as annual crop land. Pasture conditions are good, with the exception of the flooded areas.


Varying amounts of rainfall occurred throughout the Eastern Region, ranging from 3 to 25 mm. The higher temperatures last week were welcome and crop growth responded, but standing water can still be seen on many fields. Across the region, extreme variability of moisture levels and crop conditions is evident. In areas that have received less precipitation, crops are looking better than areas receiving too much rainfall. However, precipitation and cool temperatures over the weekend slowed crop growth again. An extended warm dry period would be welcome to allow crops to advance and to dry fields.  
Winter wheat started to show the effects of excess moisture stress. Dead or stressed areas in the fields became more defined in the spring cereals, canola, soybeans, sunflower and corn over the past week. Yield expectations for all crops are being estimated at below average. Some fields with low yield potential will not be receiving any further inputs. Corn and sunflower stages rapidly advanced in the heat, and soybeans started flowering.
Producers are trying to complete herbicide spraying but wet field conditions are hampering applications.  First application of herbicides has not occurred on some fields, and some will not be sprayed as they are inaccessible by ground rig. In other cases, crop yield potential does not justify further inputs. Fungicide on spring wheat and canola are being applied through aerial application.
Haying is in full swing with about 30% of the hay harvested. Rain on the weekend will stop haying for a couple of days. Availability of livestock water is rated as 100% adequate.



Scattered showers fell throughout the Interlake Region resulting in 15 to 25 mm of rainfall. Warm weather during the past week helped advance crop staging and also dried fields. Strong winds blew over bins and trees in the Arborg area over the weekend.
Crop spraying is being completed by ground rigs and by airplanes. Fungicide application is on-going in spring cereals for fusarium head blight and leaf diseases, as well as canola fields for sclerotinia. Some late applications of herbicides are still on-going due to excess moisture conditions. Crop damage can now be seen where overland flooding occurred earlier in the month. Canola and spring cereals are showing the most damage. Soybeans appear to be handling the excess moisture doing better than most other crops. Soybean and corn development has been slowed due to cooler weather.  However, with the recent warmer weather crop development has advanced. Grasshoppers are still an issue in some cereal and forage fields in the North Interlake.
Pasture and hayland affected by recent huge rainfall events, as well as those affected by high lake levels, are suffering from excess moisture stress or flooded conditions. Production and quality will be reduced as a consequence. Dugout conditions are good.
