Crop Report: Issue 8, June 22, 2015


Weekly Provincial Summary

  •  The good growing conditions are benefiting crops across Manitoba. Areas in the Northwest Region would benefit from additional precipitation as symptoms of moisture stress are evident in some fields.
  • Herbicide applications continue. Fungicide applications are also on-going, largely in winter wheat and spring wheat crops, for management of leaf diseases and fusarium head blight.
  • Haying operations continue as weather conditions allow. 



Southwest Region

In the Southwest Region, thundershowers over the past week resulted in precipitation amounts of 10 to 25 mm. Temperatures dropped to near zero degrees Celsius earlier in the week in areas in and along Highway #45 south of Riding Mountain National Park. However, heavy dews and fog that accompanied the cool temperatures resulted in little to no crop injury.


Cereal crops progressed rapidly over the past week. Early seeded crops are moving into the flag leaf stage and later seeded crops are tillering. There is no major disease or insect issues in cereal crops reported to date. Canola fields that were not reseeded are approaching bolting stage and several producers have completed a second application of herbicide. Reseeded canola acres have emerged extremely well and are in the 3 to 4 leaf stage.

Soybeans continue to respond to the good growing conditions and are in the expanded second trifoliate stage of development; many fields are receiving a second herbicide application. Most of the flax acres are at the stem extension stage. Sunflowers and corn are also progressing well with the warmer temperatures.

Winter cereal crops are heading, with fall rye close to fully headed and winter wheat about 50% headed. Some producers are spraying winter wheat for disease management. Some frost damage is becoming more noticeable with the heading of fall rye.

Weed control measures are 75 to 80% complete across the region.

Flea beetle feeding in canola is less of a concern with the more advanced stage of canola growth and the improved growing conditions.

Minimal precipitation and warm temperatures have forages and pastures growing well. There is the possibility of some first cut beginning this week; however, preliminary yield estimates are below normal. Livestock are moved to pasture with no supplemental feeding necessary. Some pastures grazed early this spring are starting to show signs of stress. Access to dry pasture in the extreme southwest remains a challenge for many producers. Dugout levels remain at 75 to 85% of capacity, with the exception of the extreme southwest remaining saturated.



Northwest Region

Scattered showers and thunderstorms once again moved through the Northwest Region over the weekend. Rainfall amounts were variable, with only trace amounts in Swan River, 13 mm in the Roblin area and 25 mm in The Pas. Most areas throughout the region, with the exceptions of The Pas and the southern part of the region, are still in need of additional rain with crops starting to exhibit stress symptoms from lack of moisture.

The majority of cereals are at seedling/tillering stages with some wheat acres heading out on sandier soils. Generally, canola is still in the seedling stage, while those acres in the Swan River Valley that were not reseeded are in the rosette stage. Cereals in the Northwest Region are in excellent to good condition while canola ranges from fair to poor as a result of dry conditions and reseeding due to frost.  Soybeans are in the vegetative stage heading into third trifoliate.
Weed control operations continue as wind and weather conditions allow. Some early seeded crops are approaching stages for fungicide application if warranted.
Spotty rain showers over the weekend resulted in much needed moisture for hay fields and pastures in some areas of the Northwest Region. Pastures and hay fields are maturing rapidly due to heat and reduced moisture conditions. Some fields are being impacted from the lack of moisture in the Roblin and Swan River areas. Alfalfa weevil is being reported in the Eddystone area with extensive damage noted on some fields. Water supply for cattle on pastures is adequate.

Central Region

In the Central Region, rainfall amounts over the past week ranged from 12 to 25 mm, with no major weather events reported. Seeding is reported as 100% complete, including reseeding.
Cereal crops throughout the region are looking good with the crops taking advantage of the cooler, wetter conditions earlier in spring. Spring cereals such as barley and early planted spring wheat fields have begun to heading. Canola stands are thinner than desired, but are starting to fill in. There is a wide range in canola development due to the varied seeding dates, particularly with reseeding having been necessary for many. A few fields are beginning to flower. There are reports of stressed canola fields bolting with plants only at 6 to 8 inches tall.
Soybeans are in the second to third trifoliate and have begun to nodulate. Iron deficiency chlorosis is reported in a few fields; the soybeans should grow out of this with the upcoming warm weather forecasted.  Soybeans have seen the first pass of herbicide complete and growers are evaluating stands for timing of second application. Corn development ranges from V1 to V5 growth stage.
Winter wheat fungicide applications began last week with the emergence of the flag leaf. Earlier fields have also begun to head and started flowering. Most growers will be targeting heading stage to help manage fusarium head blight.
Most producers have caught up on herbicide applications and have completed spraying cereals and oilseed crops such as canola.
Alfalfa first cut for high quality hay for the export market and local dairy producers has progressed well. Alfalfa grass first cut started this week and expected to continue as weather permits; preliminary yield estimates are average. Pasture growth is very good with the abundant moisture and warmer temperatures. Rain has replenished dugouts and water supplies are considered adequate.

Eastern Region

Rainfall accumulations in the Eastern Region ranged from 2 mm to over 23 mm. For most of the week, good growing conditions occurred and crop development progressed. Soil moisture conditions on crop land, hay and pasture land are rated as adequate to surplus.
Field crop seeding is complete in the Eastern Region. Cereal crops range in development from early flag leaf to head emergence. Winter wheat is heading. Canola development ranges from rosette to early flowering. Soybeans range from VC2 to V3 with nodulation starting up, sunflowers V4 to V7, and corn V5 to V6 stages.
First pass post-emergent herbicide applications are 90% complete. In southern districts, some aerial applications were done to avoid tire track damage in wet fields. Lots of first pass herbicide application is done and some producers are on to second passes. Fungicide applications at flag leaf timing are 20% done in spring wheat and about 5% done for winter wheat Fungicide applications for suppression of fusarium head blight in spring wheat will start in about ten days. There is relatively low flag leaf disease pressure in spring wheat so far; disease pressure was higher in the winter wheat crop.
Some transitional nutrient deficiencies (nitrogen or sulphur) in cereals, corn and soybean (as nitrogen fixation begins) is noted. Such effects are mostly due to recent growing conditions.
Across the region, majority of hay and pasture lands are in fair to good condition. Some producers are waiting for fields to dry prior to seeding greenfeed. First cut in alfalfa fields continues; early yields estimates are slightly below average. It is estimated 70% is standing, 10% of hay acres is cut and 20% is baled or put up as silage. Pastures are slow in growing due to cool nights and the past precipitation. Ninety-five percent of the livestock are out on pasture.

Interlake Region

Trace amounts of precipitation were recorded throughout the Interlake Region last week. Teulon had the highest recorded amount at 12 mm. The rest of the region varied in amounts from 2 to 8 mm. Warm temperatures were experienced throughout the week which helped promote plant growth in crops, hay fields, and pastures. Regions in the north Interlake would benefit from more rainfall.
Seeding throughout the Interlake Region is complete. Spring cereal crops staging vary from 2 to 3 leaves to stem elongation; some early seeded barley fields are starting to head. Canola staging varies from 1 to 2 true leaf stage to some fields starting to bolt in the next couple days. Soybeans are at the 2 to 3 trifoliate stage and corn staging is at 3 to 5 leaf stage. Most forage grass seed fields have already headed out.
Field conditions are good for pesticide application by ground sprayers. Herbicide spraying is still on-going as second applications are occurring on canola and soybean fields. Spraying winter wheat fields for suppression of fusarium head blight has been and will continue for the next couple days as winter wheat crops head out and start to flower.
Spraying in alfalfa seed fields is nearly completed as insect pressures decrease. High diamondback moth counts in northwest Interlake, especially near Lake Manitoba.
Pastures in the Interlake Region are in good condition with last week’s light showers and warmer temperatures. The earliest alfalfa fields are 60 to 65 cm tall and starting to flower; some haying is started, mostly by dairy producers.
