Crop Report: Issue 6, June 8, 2015


Weekly Provincial Summary

  • Seeding operations are wrapping up for the 2015 season in Manitoba with progress estimated at 97% complete.  Crop types remaining to be seeded include canola and greenfeed.
  • Reseeding of canola fields impacted by frost, insect activity, wind and excess moisture conditions is still occurring.  Producers are also busy with herbicide applications.
  • However, field operations in some areas of Manitoba were hampered by rainy weather conditions during the week and over the weekend.
  • Hail was reported in isolated areas, but to date minimal impact to crops is noted.  Assessments are on-going.


Southwest Region

Rainfall on Tuesday and over the weekend was general throughout the Southwest Region. The amount of precipitation was variable. A range of 5 to 15 mm of rain fell in the areas of Russell, Hamiota, Shoal Lake, and Minnedosa. In the Brandon and Carberry areas, a range of 10 to 20 mm was received. Larger accumulations again occurred in the southwest corner of the region with 95 mm recorded in Pierson and 62 mm in Deloraine areas. 

Overall, seeding progress is 95 to 100% complete in most of Southwest Region. Many producers were reseeding canola acres earlier in the week that had been impacted by the previous weekend’s frost event. Rainfall on Tuesday stopped seeding operations for one to two days, which allowed some producers to reassess additional canola and flax fields and decide whether to reseed or not. It is estimated about 50 to 60% of the canola acres are being reseeded, in mostly northern areas of the Southwest Region.
Winter and spring cereals also exhibited frost injury symptoms, but most crops are showing signs of recovery. The majority of the winter wheat was just entering the stem elongation stage of development and looks to have escaped significant injury. There remains some concern with fall rye crops as many were in the vulnerable boot stage of development. Early planted spring cereals are in the five leaf stage.

Soybeans responded well to the warmer temperatures. Excellent emergence has been noted with the majority of acres having emerged in 7 to 10 days. Fortunately, most of the soybeans had not yet emerged prior to the May 30 frost.  

Weed control measures in all crops have resumed. However, the lack of any significant rainfall in some areas of the region has slowed crop growth and weed emergence. This is resulting in producers delaying applications. In other areas, excess moisture is hindering herbicide applications.
Flea beetle activity in canola continues to be a major issue in many fields and is of particular concern in fields not reseeded after the most recent frost. Foliar insecticide applications are necessary in many of these fields. Diamondback moth trap counts are very low.
Forage and pasture growth remains slow as it recovers from the recent frost. It is estimated first cut alfalfa yields will be below normal. Most cattle have been moved to summer pastures. Dugouts are 80 to 90% full, with the extreme southwest areas of the region remaining very wet.

Northwest Region

Thunderstorms moved through many parts of the Northwest Region over the weekend but did not result in rainfall of any significance. Many areas of the region would benefit from additional precipitation. Day time temperatures over the week were generally quite warm, while in some areas, night time temperatures were just a couple of degrees above freezing.
Seeding is mostly finished throughout the Northwest Region, with the exception of some greenfeed acres and canola fields that have yet to be reseeded due to damage caused by frost. Most canola that was reseeded last week has yet to emerge. Where reseeding was unnecessary, about 50% of the canola is at the seedling stage. Most other crops are at the seedling stage of growth, with the exception of fall rye which has begun to head.
Annual and perennial weed growth is general throughout the region. Herbicide applications have begun depending on the crop and weed stage of growth.
Flea beetle activity in canola continues to cause concern in many parts of the region where feeding continues on slow growing, stressed and injured canola plants. Control measures are required on some canola fields in the Swan River district.
Forages and pastures are progressing rapidly as temperatures are rising. Alfalfa in some areas was stunted by frosts, but other fields not hit as hard are in the early bud stage. Majority of cattle have been moved to pastures. Water supplies are good.

Central Region

In the Central Region, the week began with cooler, rainy weather but producers were able to resume field operations before rain fell again over the weekend. Most of the region saw accumulations of 25 to 50 mm and more over the week. Hail was reported in the Morden area and fields are being assessed. Injury symptoms, mainly leaf damage, from the May 30 frost are noted in soybeans, corn and sunflowers. However, in some cases, damage may reduce plant stands. Crop damage due to excess moisture in low lying areas of fields is evident in places, and more is expected following the weekend rains.
Seeding is reported at over 97% complete in the Central Region and should wrap up this week, including any reseeding that is needed.
Spring cereals are growing well with good tillering noted. Early seeded canola was stressed due to cold soils and plant stands are less than desirable. Flea beetle injury is an added stress, as is excess moisture in some areas of the region, along with damage due to high winds. Canola development ranges from emerging to 3 to 4 leaf, and some fields will reach rosette stage this week.
Peas are up to the six node stage. Soybeans are emerging to the first trifoliate stage. Producers are waiting for the first trifoliate stage in soybeans to undertake rolling, where circumstances didn’t allow immediately after seeding. Many early seeded fields are reported as having heavy weed pressure, as pre-seed and pre-emergent herbicide applications were not made. Early seeded fields are expected to be short in height.
The last of the edible bean fields are being seeded. Warmer temperatures improved corn stands. Staging ranges from V2 to V3. Sunflower development ranges from emerging to two true leaves.
Winter wheat and fall rye are reported to be in good to excellent condition, with only a fraction of acres rated as fair. The crops are in full flag leaf to early heading stage.
Advanced crop and/or weed stages are making it to difficult to time herbicide applications. Yellowing is seen in some cereal crops, and also some canola fields. Poor weed control is also reported where herbicide applications were made less than 2 to 3 days after frost. The recent rainy weather has also made herbicide applications a struggle; some spring wheat acres may grow beyond staging for grass weed herbicides. Thinner canola stands will require careful monitoring for weed problems.
Grass weeds, including volunteer cereals, are prevalent. Broadleaf weed concerns include wild buckwheat, smartweed, lamb’s quarters, and volunteer canola. Winter annuals are flowering and setting seed, and curled dock and Canada thistle are a concern in some fields.
Flea beetles continue to be the main insect concern. Spraying the headlands of fields continues, and some entire fields have been sprayed. Careful monitoring is required in fields that are under environmental stress with less than optimal stands. Some cutworm injury is reported and fields have been sprayed, including sunflower, edible bean, as well as soybean. Monitoring continues. Diamondback moth trap numbers are average to low in number.
Rainfall improved pasture and hay field conditions, and forages are growing quickly with the moisture and warmer temperatures. Grasses are starting to head out. The most advanced alfalfa is in the late bud stage. The first cut for high quality alfalfa was made late last week and will continue as conditions allow. Frost damage was reported above the escarpment, but warmer temperatures improved growth. Cattle have been moved to pasture. Hay fields which had a late cut taken last fall are slower to regrow this spring, but are catching up. Regrowth on pasture that had cattle turned out early is slow to resume. Water supplies are rated as good.

Eastern Region

Rainfall accumulations in the Eastern Region ranged from 12 to 70 mm with the central and southern districts receiving greater levels of both mid-week and weekend precipitation. Field operations are currently halted across most of the region. Soil moisture conditions on crop land, hay and pasture land are rated as adequate to surplus.
Seeding was completed in the northern and central districts of the Eastern Region. Southern districts are 90% complete with primarily canola still to be seeded. Reseeding of canola fields was occurring across the Eastern Region last week.
Cereals range in development from two to six leaves and two tillers. Canola ranges from emerging to the six leaf stage. Soybeans range from VE to V1, sunflowers VE to early V4, and corn V2 to V3 stages. By the end of last week, winter wheat was entering the flag leaf stage with some fungicide applications planned for this week.
Herbicide applications were in full swing across the Eastern Region last week whenever field access was possible. The focus was on pre-emergent applications and post-emergent applications on crops planted before the May long weekend. Priority was given to herbicide applications in early seeded cereal crops that would soon be advanced beyond desired growth stages. Herbicide applications are set to resume this week as soon as fields become accessible. Spraying for flea beetles continued as warranted.
Across the region, the majority of hay and pasture lands are in fair to good condition. Approximately 90% of the livestock are on pasture. Mixed hay fields have slower growth noted as alfalfa fields are slightly ahead. Dugouts are full and availability of livestock water is rated as adequate.

Interlake Region

Warm temperatures, along with scattered showers, were recorded throughout the Interlake Region. Precipitation amounts ranged from 2 to 15 mm. Isolated thunderstorms in the South Interlake near Winnipeg brought hail and rainfall over 25 mm throughout the weekend.
Seeding in the Interlake Region is nearly done, with progress estimated at 95 to 100% complete. Some late seeding of canola and spring cereals for greenfeed is still occurring.
Most cereals range in development from 2 to 6 leaf with tillers, canola ranges from cotyledon to 4 leaf, corn 2 to 4 leaf stage, and soybeans unifoliate to second trifoliate stage. Forage seed crops progressed rapidly last week due to the warmer temperatures. Leafcutter bee producers will soon be getting ready to begin their bee incubation prior to pre-bloom in alfalfa.
In-crop herbicide applications are occurring, with producers spraying cereals, canola, soybeans, and other crops. Field conditions are good and can be easily travelled on without making ruts.
Milder weather aided pasture and hay growth following low night temperatures and frost events over the past few weeks. Older hay fields are showing more signs of frost damage than newer stands.
