Reporting Area Map Crop Weather Report Past Reports
 

Weekly Provincial Summary 

  • Strong weather systems passed through several areas of Manitoba throughout the week. Heavy rains and strong winds halted harvest operations and resulted in lodging of crops.However, harvest did resume where field and weather conditions allowed.
  • Winter wheat yields are ranging from 50 to 95 bushels per acre, with good quality reported to date.
  • Swathing or pre-harvest applications in the earliest-seeded spring cereal and canola crops has started.
  • There were also a few fields of spring wheat, barley, oat and field peas harvested last week; yield or quality not yet reported.
  • A return to warmer and drier weather conditions would be welcome to improve field conditions in areas where excess moisture is a concern, for continued growth in the warm season crops such as grain corn, sunflowers, edible beans and soybeans, and harvest operations.
 

Southwest Region

Rainfall at the beginning of last week brought large isolated rain and wind events to several areas in the Southwest Region, including Russell, Shoal Lake, Oakburn and Erickson. Precipitation amounts varied from 10 to 75 mm. There was also a large system that went through east of Wayans in the Glenbrook area. Reports of high winds and rainfall amounts of 70 to 80 mm. Warm, drier weather during the week helped producers with haying and get ready for harvest towards the end of the week.
 
Winter wheat and fall rye harvest started this past week with most reports of an average yield with good quality. Some reports of ergot in fall rye. Cereal crops continue to progress and some of the early seeded crops are being cut or a pre-harvest is being applied. Fusarium head blight visible in most wheat crops but impact to yield and quality is yet unknown. Canola crops are in the pod fill stage. Sclerotinia is visible in several fields. Flax is done flowering and is filling. Peas are in the early stage of harvest with most having a pre-harvest product applied. Sunflowers are flowering and have progressed well during the warm, humid conditions. Corn is looking extremely good in the area. Soybeans continue to flower and are in the R3 to R5 stage.
 
No major insect issues are reported in the region.
 
Last week enabled several producers to catch up with haying. First cut is mature, resulting in quicker dry down. Yields are above average with average quality. Dugouts are 100% full.
 

Northwest Region

There was hot weather throughout the Northwest Region over the week, along with varied rainfall amounts. Precipitation ranged from trace in The Pas, 15 to 40 mm in Swan River to excessive rainfall received over a short period of time in many southern parts of the region. Areas around Fork River, Winnipegosis and Rorketon received upwards of 125 to 175 mm, and north of Roblin upwards of 100 mm. Some crop lodging due to rain and/or wind is evident throughout the entire region and crop damage is likely in lower areas where water is ponding.
 
Soil moisture conditions are variable, ranging from adequate in most areas to excessive in those areas receiving high rainfall amounts over the past week. Crops in these areas are showing the effects of excessive moisture with yellowing and crop loss in low lying areas. In general, most field crops throughout the region continue to advance nicely and are in relatively good condition, with the exception of poor crops in those areas impacted by too much moisture.
 
Crops are advancing rapidly with the hot weather. Fall rye and winter wheat crops are maturing and winter cereal harvesting is underway in the Dauphin and Roblin areas. The perennial ryegrass harvest is also underway. Some barley is harvested in the Ste. Rose area. Spring wheat is maturing quickly with the heat; some areas have potential for high protein wheat. Canola continues to develop rapidly with most canola fields podding. Field peas are also advancing quickly with most fields podded and reports of some fields being desiccated in the Swan River area.
Aster yellows are reported in canola in the Swan Valley; low levels are reported to date. Some oat blast in the Roblin area has been reported and fusarium head blight is present in wheat. As well, humidity is causing some white mould and powdery mildew in peas, and sclerotinia in canola where fungicide was not applied.
 
Producers are still trying to complete first cut but frequent rains continue to delay‎ operations. As well, second cut harvest will continue once weather clears. Second cut hay and some native hay access will be affected due to wet field soil conditions in areas receiving high amounts of rainfall. In areas with less rainfall, cereal silage harvest has begun with early reports indicating yields at 11 tons per acre. Pastures remain in good condition.
 

Central Region

Warm temperatures through the week in the Central Region allowed for continued rapid crop growth. Unsettled weather resulted in all parts of the region receiving some rain, ranging from 15 to 50 mm and more. A major storm system blew through the region on Wednesday, with the most significant impact in the Morden, Winkler, Roland and Baldur areas. A tornado was reported in the Baldur area. Wind speeds reached 111 km/hour in areas. Substantial damage was sustained; many trees are down and there is damage to homes, barns, sheds and bins. Crops, including sunflowers, were flattened.
 
High humidity continues to limit drying conditions, increasing potential for disease in crops, and interfering with haying operations. Standing water is still a concern. Yellowing and crop thinning due to excess moisture is evident. Field access continues to be an issue, and field activity is limited by poor conditions. Road access is also a concern in places where rapid runoff damaged roads.
 
Fall rye and winter wheat harvest continues, although delayed by the rains. Crops are in good to excellent condition, although water damage is evident. Field access is an issue, with ruts being made during harvest operations. Some fusarium head blight is noticeable. Yields range from 65 to over 100 bu/acre in winter wheat to date, with good quality. Preliminary protein levels range from 11 to 11.5%. Early yield reports of 75 to 90 bu/acre for fall rye; some ergot reported.
 
Cereals continue to advance and early seeded crops have matured. Pre-harvest applications continue. Lodging continues to be an issue, a result of high winds and thunderstorm activity. Fusarium head blight is noticeable in fields but at relatively low levels. Some spring wheat and barley are combined; no yield reports yet. Some oat fields are swathed. The later seeded canola is growing rapidly and flowering is almost complete. Early seeded canola is fully podded with seed colour change in lower pods. Swathing has started in the earliest fields. Lodging is evident, due to high winds and soft field conditions. Sclerotinia infections are becoming more evident, resulting in premature ripening.
 
Many pea fields have dried down. Stands look good where excess moisture is not an issue. Boll formation is complete in most flax fields and colour change is evident. Some perennial ryegrass has been cut. No yield reports to date.

Corn is growing rapidly. Soybeans continue to flower and pod. Many fields range from R4 to R5.5. Iron deficiency chlorosis is still noticeable in a number of fields, although recovery has been seen when fields dry. Bacterial blight is evident in many fields. Flowering in edible beans is mostly complete. Fields are stressed due to excessive rainfall. There are reports of white mould showing up in fields where canopy is dense. Sunflowers are flowering and in the R4 to R5.5 stage; fields are being monitored for head insects.
 
Beneficial predators are evident in good numbers in most fields. Insect monitoring continues for insects including lygus, aphids and grasshoppers, with numbers low to date.
 
Good growth of forages continues, as does second cut. Lots of hay was harvested last week when conditions allowed. High humidity is an issue for drying of swaths. Many producers are wrapping bales. Some greenfeed and cereals are being cut for silage. With late cutting of forages due to the wet weather conditions, nutritional value of forages is lower and fibre content is higher. There is abundant grass growth in pastures. Livestock water supply is adequate.
 

Eastern Region

The weather last week in the Eastern Region was highly variable, ranging from sunny and reasonably warm but then transitioning quickly to cloud and showers or intense thunderstorms. Rainfall accumulation across the region varied from as little as 6 mm to more than 50 mm in some southern districts. Overnight Wednesday and Thursday of last week were marked with intense thunderstorms including lightning and high winds. Areas that received lesser amounts of rain made some progress with fields drying up and getting access to fields for pre-harvest spray applications and winter cereal harvesting. Crop development in warm season crops continued to accelerate in these conditions.
 
Winter cereals in the Eastern Region are mature with harvesting as much as 75% done in some districts. Yields are in the 50 to over 80 bu/acre range. Spring cereals are at hard dough to physiologically mature and pre-harvest applications are as much as 65% done in some areas. Canola ranges from late pod filling to physiologically mature with swathing or pre-harvest applications started. Field peas range from late pod filling to physiologically mature with pre-harvest applications started. The soybean crop is mostly at the R5 (seed development/pod filling) growth stage. Sunflowers are in early to mid flowering stages (R5).
 
Across the region, 60% of hay land is rated in good to fair condition with the remaining rated as poor to very poor. First cut haying progress is noted as 15% baled or silaged with an additional 10% cut and the remainder of the crop still standing. Second cut haying progress is 40% baled or silaged with 10% cut and the remainder of the crop still standing. Quality is noted as mostly good with first cut alfalfa hay yielding 2 tons/acre and first cut grass/alfalfa hay yielding 1.75 tons/acre. Second cut alfalfa hay was yielding 1.5 tons/acre. The majority of pastureland is rated as in good condition. Availability of livestock water was adequate.
 

Interlake Region

Warm temperatures and scattered showers were experienced throughout the Interlake Region last week. Rainfall amounts varied in the region from 5 to 15 mm. There was the exception in the Ashern area were rainfall amounts varied from 40 to 80 mm on Thursday.
 
Harvest has begun in the Interlake Region with progress estimated to be less than 5% complete. In the South Interlake, producers have been harvesting and some have completed winter wheat. Reports of yields averaging 60 to 70 bu/acre with trace amounts of fusarium damaged kernels. Forage grass seed fields are being harvested with average yields. Producers also started field peas with yields in the mid 40 to 50 bu/acre range. Spring cereals continue to be swathed or have a pre-harvest herbicide applied as the crops reach maturity. The later seeded spring wheat fields are entering the milk stage. Swathing of canola fields has started while the later seeded fields continue to flower. Soybeans continue to flower/pod and are looking good. With the moisture and heat, corn is rapidly developing. Sunflowers are flowering. Alfalfa seed fields were impacted by the recent rainfall where crop lodging is noted. Leaf cutter bees continue pollination and fill bee blocks. Majority of all timothy fields are swathed and have started to get harvested.
 
Spray applications in canola for lygus bugs are being reported. Insect pressure is low at this time. Alfalfa seed fields continue to be monitored for weevil and lygus bug pressure.
 
Haying progress is stalled by rains and high humidity. Ensiling has been a good alternative this year. Second growth of alfalfa is quite good and has been minimally affected by alfalfa weevil larvae damage. Some native and grass hay is too wet to travel on as low lying areas are flooded. Grasshopper damage so far has been minimal. Pastures are in good conditions with some flooding due to excessive recent rainfall events. There is adequate water for livestock consumption.
