Crop Report: Issue 6, June 6, 2016


Weekly Provincial Summary 

  • Seeding operations are wrapping up for the 2016 season in Manitoba with progress estimated at 99% complete. Crop types remaining to be seeded include canola and cereal crops for greenfeed and silage.
  • Many areas of Manitoba received precipitation, with the Manitoba Agriculture’s Ag-Weather Program showing accumulations ranging from 4 to 74 mm.
  • Crop injury due to excessive moisture conditions is being assessed, as well as impact to crop emergence and plant stands. Portions of fields are showing symptoms of excess moisture stress, including yellowing.
  • Field operations in some areas of Manitoba were hampered by the rainy weather conditions.
  • Weed control continues to be the priority for producers as crops and weeds advance.
  • Dairy producers are starting first cut haying operations.

Southwest Region

Rainfall received over the entire Southwest Region last week was welcome as most areas had dry soil conditions. Rainfall amounts varied from 25 to 50 mm with some areas reporting higher amounts in thundershowers. An area including Melita, Pierson, Tilston and Reston report total rainfall of 90 to 100 mm over the past fourteen days. Rainfall on the weekend in some areas added another 10 to 20 mm in spotty thunderstorms. High winds and a funnel cloud were reported in the Elgin/Hartney area.
Most cereal crops are planted except for some silage and greenfeed acres. Most cereal crops have emerged and are being sprayed. Recent rainfall and wind has hampered spraying. There are reports of cutworm and wireworm damage in some areas. The canola crop is seeded and most has emerged. Some early seeded canola was being sprayed for flea beetle control. Most peas are sprayed and are advancing well. Soybeans are advancing and vary in stage from the cotyledon to the first trifoliate.
Winter wheat crop benefited from the rain; however, it probably lost some yield potential because of the lack of moisture earlier in the season. Fall rye is heading; average yields are expected.
Overall, crops look to be in good condition in the Southwest Region. Some areas had uneven germination, but the recent precipitation will help these crop even out.
Pastures and hay land will improve from the recent rainfall. Most producers have moved cattle tol pasture. Dugouts are 85% full.

Northwest Region

Temperatures and rainfall amounts were extremely variable throughout the Northwest Region over the past week. Higher accumulations were noted in the Ste Rose/Dauphin area with up to 75 mm of rainfall in localized areas, and the Roblin area received 75 to 100 mm in the northwest part of that district. Soil moisture conditions range from adequate in some parts of the region to excessive in localized parts of the Dauphin/Ste Rose and Roblin areas. The east side of the Swan Valley is drier, having received less than 12 mm of rainfall since seeding time.
Overall seeding progress in the Northwest Region is estimated to be 98% complete. One hundred percent of the wheat crop is seeded and has emerged. About 60% of the wheat is at the tillering stage of growth. One hundred percent of the canola crop is seeded with approximately 90% of the crop nicely emerged. Approximately 95% of the soybeans are seeded and 85% of those have emerged. Soybean emergence is reasonably uniform.
Herbicide treatments have started and will continue as field conditions allow and as crops reach the proper stage for application. There continue to be reports of flea beetle activity in some canola fields in the Swan River Valley and Roblin areas, but injury caused is minimal in many cases. There are reports of cutworms at and above threshold levels in canola, field peas and corn crops in the Swan River Valley. Some of those fields required treatment for cutworms and others had to be reseeded. Diamondback moth monitoring trap populations are highest in The Pas and Swan Valley areas.
Most hay fields are in good condition with the most advanced alfalfa in the bud stage. However, there are areas across the region experiencing drier conditions and would benefit from rainfall. Many animals have been hauled to pasture with the rest being moved this week.

Central Region

Rainfall was general over the entire Central Region, but variable. Precipitation ranged from 15 to 75 mm for the week, with most areas receiving 25 to 45 mm range. Good drying conditions on Sunday were followed by rainfall overnight. All areas have adequate to excessive moisture. Standing water remains in some fields. Water in drainage ditches is dropping, which will enable some additional water to come off fields. Yellowing of crop due to excess moisture is becoming more widespread; good drying conditions are needed, especially for the heavier clays.
Seeding is reported to be essentially complete in the region. Emergence has been rapid with warmer temperatures and moisture.
Cereals are growing rapidly and most fields are tillering. A few of the most advanced fields are close to flag leave. Seed in the equipment tracks has germinated, and fields will have variable crop staging as a result. Herbicide treatments continue as field and weather conditions allow, but there are delays with the rapid weed emergence and growth. Most sprayers have been at a standstill since early last week.
Seeding of canola is almost complete; very few fields remain to be seeded or re-seeded. The crop is emerging rapidly, and earlier seeded fields continue to fill in. Later germinating plants will result in variable crop staging within fields. Flea beetle pressure continues to be a concern, although limited in scope. Some fields or field headlands require treatment.
Corn planting is complete. Growth is rapid with the recent moisture and warmer temperatures; staging ranges from emerging to six leaf. Sunflowers are emerging to two leaf stage. Flax is 5 to 10 cm in height.
Soybean seeding is complete. Fields are emerging to first trifoliate stage; rapid growth is expected with the recent warmer temperatures. Peas are advancing, with a number beyond the six node stage; herbicide choices become more limited for those more advanced fields. Fields still within stage will be the priority for herbicide applications as field conditions improve. Plants are fairly short due to the earlier cool temperatures and dry soil conditions. A few edible beans remain to go in; Altona area is complete.
Fall rye is headed and flowering; winter wheat is at the flag leaf stage. Some fungicide applications are being made as conditions are conducive for development of leaf diseases; some will wait for head emergence and fusarium head blight timing.
Dandelions and winter annuals are blooming. Curled dock and Canada thistle are also plentiful. Weed growth has been rapid with the recent moisture and warmer temperatures. Before the rains, spraying had focused on first pass glyphosate on soybeans, and early grass control and broadleaf in canola. Herbicide applications will now be a challenge due to timing and field conditions.
Some cutworm activity is reported, with some fields requiring treatment of affected areas. Total area affected is minimal. Diamondback moth numbers to date are generally low to moderate. No reports of significant disease pressure in crops to date. Some tan spot is noted in spring wheat fields.
Forages are growing quickly with alfalfa as advanced as late bud stage, up to 71 cm in height. The first alfalfa flowers are becoming visible and tame grasses are heading out. First cut dairy hay has begun. With the recent rainfalls, forage growth is now abundant on most pastures to meet cattle requirements. Livestock water supply is adequate.

Eastern Region

Rainfall accumulation in Eastern Region ranged from 25 to 45 mm. The week started with saturated soil conditions due to the 20 to 50 mm of rainfall at end of the previous week and weekend. Fields are saturated and ponding of water is very evident. Field operations were at a standstill until only recently where there was some isolated spraying in drier fields that were passable. Impact of wet conditions and moisture stress to yield is unknown. Producers are concerned with crop and weed staging and being able to spray. Good drying conditions would be welcomed and the forecast for the coming week looks favourable.
With the cool, wet weather of the past week producers were unable to complete seeding. There may be some producers switching to canola from soybeans.
Cereals are in the 3 to 4 leaf and tillering stage. Canola is in the early rosette to four leaf stage with the newest leaf emerging. Soybeans are in the first unifoliate leaf stage. Corn is in the V3 to V5 growth stages. Winter wheat is at the start of head emergence.
Most of the spraying progress this past week was in cereals and corn. Some canola has been sprayed, as well as soybean acres.
Cutworms in canola and sunflower, as well as flea beetles on canola, have been reported but no control measures are needed to date. Powdery mildew in some winter wheat fields is noted; presence is a result of cool moist, conditions and thick canopies.
Across the region, the majority of hay land is rated in good condition with 25% of pasture land rated excellent, 50% rated good and 25% rated fair. Forage cutting has begun in the region but the recent wet weather has slowed progress. No yield estimate on the first cut is available yet. Most livestock are on pasture with the grass being 15 to 25 cm tall. Availability of livestock water is adequate and dugouts are full.

Interlake Region

Cool temperatures and scattered thunderstorms occurred throughout the Interlake Region last week. East Selkirk, Teulon and Woodlands accumulated 30 to 35 mm of rainfall last week. Arborg, Eriksdale, Moosehorn and Narcisse had lesser amounts ranging from 20 to 30 mm. Early last week, Winnipeg Beach, Teulon and surrounding areas received heavy rainfall causing water ponding on fields. Areas surrounding the Arborg, Riverton, Fisher Branch and Arnes saw three separate rain events on the weekend with heavy periods of rainfall and hail.
Seeding progress throughout the Interlake Region is estimated to be 95% complete. There are small pockets of land that producers have not yet been able to enter in the Arborg area due to excess moisture conditions.
Spring cereals range from 3 to 5 leaf stage and are starting to tiller. Canola continues to emerge and the earlier seeded fields are filling out nicely. Soybeans range from unifoliate to first trifoliate stage. There are several soybean fields in north Interlake that have emerged and still need to be rolled. Forage seed fields, typically alfalfa, continue to be sprayed for weed control and swept to monitor insect pressure. Grain corn and sunflowers staging varies from emerging to 3 to 4 leaf stage. It will still be several days before most ground sprayers are able to get onto fields without making ruts. Overall, crops look fine but in areas where moisture is an issue crop injury is evident.
Cool temperatures and scattered rains encouraged hay and pasture development and growth of forages. Alfalfa is in early to late bud stage. Pastures are rated in good to excellent condition. Most cattle are on pasture. There is adequate water for livestock to drink.
