Crop Report: Issue 11, July 16, 2018

Weekly Provincial Summary
  • Hot temperatures continue to advance crops across Manitoba.  The majority of the province would benefit from a good rain. 
  • Majority of acres and crop types are in the flowering and grain fill stages of development. 
  • Disease pressure and insect activity continues to be monitored as the growing season progresses. 
  • Haying continues, yields are below normal.   


Southwest Region
Areas north of highway 1 received small amounts of rain over the past week; larger amounts fell in the southern part of the region.   Melita, Virden, Pierson and Wawanesa received around 25 mm of rain.  Hot and windy conditions are drying up moisture very quickly and worsening conditions in areas that did not get recent rains. Crops are showing the effects of the very hot temperatures.  The majority of the southwest region could use a good rain.   
Winter wheat and fall rye are in the dough stage and are starting to turn. Most spring cereal crops are in the milk to early dough stage.  Some early seeded barley is starting to turn. 
Peas have completed flowering for the most part and are in the pod fill stage.  The majority of canola is still flowering with some starting to come out of flower. Corn and sunflowers are progressing well.  The majority of soybeans are in the R3 stage.   Some nodulation issues have been reported.   
There are no major insect or disease issues to date.  Bertha armyworm populations continue to be monitored.  Trap counts have reached the uncertain risk range in parts of the southwest. 
The southwest region remains hot and very windy, which has made for favorable haying weather. Some dugouts and sloughs are very low and producers are looking at pumping water.
Northwest Region
This past week there were good growing conditions throughout the region with scattered light showers and daytime temperatures nearing or over 30°C; Birch River hit a high of 38°C.  There were high winds over the weekend but no reports of damage.  Rainfall was relatively light with Grandview, The Pas, San Clara and areas around Roblin getting roughly 13 mm of precipitation.  Water remains in low-lying areas and saturated fields around Roblin and The Pas due to the high water table.  Soil moisture conditions remain dry in the McCreary area.     
Winter cereals are in the milk stage with winter wheat in the Dauphin area in the dough stage.  Spring cereals are heading/flowering, with approximately 30% in the dough stage. With the heat, some of the early seeded wheat is starting to turn. Canola is flowering with 30% podding. Soybeans are largely flowering and starting to pod. Fifty percent of the flax crop is flowering. Throughout the region the crop is mostly rated as good with 30% rated as being in excellent condition.
Fungicide and herbicide applications are occurring as the crops reach the appropriate stage and as weather and field conditions allow.  Bertha armyworm trap counts continue to climb in areas of the region; with traps in the Swan River and Russell areas reaching an “uncertain risk” rating.
Haying is progressing across the region. Areas that had dry conditions earlier in the season and areas that remain dry are reporting yields at half to 75% of normal. Fields that received timely rains are producing average yields. Rainfall and wet conditions are affecting haying operations at The Pas. Pasture conditions are generally good, with the exception of areas around Dauphin and Ste. Rose where conditions are deteriorating due to dry conditions. Dugout levels are low to adequate.  
Central Region
Hot, sunny, dry and windy conditions prevailed during the week. Daytime temperatures reached a high of 34°C in a few locations across the region. Rain showers brought variable amounts of precipitation ranging from 2 mm in the Plumas area to 30 mm in the St-Claude area. Growing conditions are generally favorable with the higher temperatures and fair soil moisture. Some areas in the northwestern and southeastern parts of the region missed early season precipitation and as a result, crop stands suffer.
Winter cereals are in the dough stage and are turning colour.  Spring cereals are finishing flowering and advancing rapidly into the milk to early dough stage.  Fungicide applications for fusarium head blight and foliar diseases are complete. Corn is growing fast and many fields are tasselling while the most advanced are in the silking stage.
Canola development varies.  On the escarpment many fields are still flowering but nearing the end while in the Red River Valley canola is mostly finished flowering.  Flax is progressing through flowering and bolls are forming. Sunflowers are in the bud development to early flowering stage. Field peas are in late flower and pod development is progressing rapidly.
Soybeans are in the beginning pod (R3) to full pod (R4) stage and most advanced in the Red River valley. Some fields were showing symptoms of Iron Deficiency Chlorosis but are recovering. Some root rot, brown spot and bacterial blight have been reported but the crop is developing well.  Edible bean fields are showing good growth.
Potato fields are growing well and flowering. The high temperatures are stressful and irrigation is applied as needed. Fungicide applications to protect against blight are done following a regular schedule.
Diamondback moth larvae have been noticed feeding in some canola fields in the Morris area. Bertha armyworm trap counts are highly variable at this early stage of monitoring. No reports of larvae populations reaching economic levels in canola.  Grasshoppers have been noticed in some fields. Growers are keeping an eye on population to determine if spraying is required.
Pasture conditions are rated as fair but vary with the moisture conditions. First cut of alfalfa is wrapping up. Hay yields are below normal due to the dry conditions of the start of the season. Second cut alfalfa is growing fairly where moisture is adequate, but yields will be reduced in many areas from lack of moisture. A good soaking rain would be beneficial for all forage stands to stimulate growth. Livestock producers are looking for alternative feed sources to complement their needs. Livestock water supply is adequate at this time.
Eastern Region
Rainfall amounts varied this week across the Eastern Region with areas receiving as little as less than 1 mm to greater than 35 mm. Central and southern districts received higher rainfall accumulations in general while northern districts experienced a mixture of light rains and localized higher accumulations. Hot and humid weather continued throughout the week.  Soil moisture conditions on cropland were rated as about 90% adequate in northern and central districts.  In southern districts, soil moisture conditions on crop land were rated as 50% adequate, 25% short and 25% very short. 
Warm temperatures accelerated crop growth.  Winter wheat is in the soft dough stage.  Spring cereals are in the milk stage. Canola is pod filling with some flowering, but flowering is coming to an end in many fields.  Soybeans are mostly in the R3 growth stage and moved rapidly from flowering to pod development.  In many soybean fields, areas that were still yellow really greened up last week.  Sunflowers are in late R3 to R4 growth stages and also moved rapidly past earlier bud development stages.  Corn is in the V10 to V11 growth stage and beginning to tassel.  While all crops, on average, are looking good at this point, more rainfall in the coming weeks will be important to maintain their condition and yield potential. 
Herbicide and fungicide spraying is complete.  There have been few concerns regarding insect damage to crops at this time.  A limited amount of cereal acres were sprayed for armyworms last week and scouting continues. 
Hay and pasture land moisture conditions were rated as 50% adequate, 25% short and 25% very short.  Hay and pasture land crop conditions were rated as 40% good, 20% fair, 20% poor and 20% very poor.  Beef producers are busy putting up feed and dairy producers are starting second cut.  Pastures are holding their own as producers rotate between paddocks.  Dugouts are about half full.  In terms of haying progress on first cut, 40% is standing, 20% is cut and 40% has been baled or silaged. Quality has been good.  Yields have been 1.5 tons/acre for alfalfa, 1.25 tons/acre for grass/alfalfa hay, 0.75 tons/acre for tame hay and 0.5 tons/acre for wild hay.  About 10% of second cut hay has been cut with good quality being expected at this point.  
Interlake Region
Temperatures remained in the high 20°C to mid-30°C range for most of the week. Rapid crop growth in most areas, where sufficient moisture is available. Rainfall amounts continue to be variable, with scattered showers and thundershowers.    Some hail was reported. Strong winds and a possible tornado caused property damage in the Arborg area; damaged trees can be seen in a wider area.  The Fisher Branch- Poplarfield-Narcisse-Inwood-Arborg-Riverton-Gimli areas received 15 to 50 mm of much needed rain, with reports of as much as 75 mm in isolated areas.  Minimal amounts fell in the rest of the region. All areas continue to look for timely rains, to sustain crops and replenish soil moisture.  
Crops are advancing rapidly. Many crops are shorter than normal, a result of extended dry periods. Crops are drying up on ridges with lighter textured soil. In the driest areas, the ground is still visible in wheat fields; tillers will not contribute to yield. Barley and spring wheat fields are starting to change color.
Canola is in the late bloom stage; flowering is wrapping up and pods are formed.  Flowering period has been shorter than normal due to hot dry conditions. Soybeans are in the R2 to early R3 stage, with many flowers evident.  Iron deficiency chlorosis noticeable in some fields, but at lower levels than last year. Peas are well podded, flowering almost complete.  The earliest flax fields are finished flowering. Most sunflowers are at R2 to R4. Weather conditions have been very conducive for corn, with rapid growth evident. Most fields range from V14 to VT. Some grass seed fields affected by dry conditions have had limited seed set, and will be cut for hay. Those with good seed set are starting to be swathed.
Diamondback moth monitoring is complete; numbers are relatively low.  A couple of fields in the southeast Interlake were sprayed for diamondback larvae.  Bertha armyworm moth numbers are low to date. A few headlands have been sprayed for grasshoppers. 
First cut tame hay is over half completed with poor to average yields. Producers are moving hay from fields quicker than usual, hoping rain will bring on a second cut‎.  A few producers are seeding millet after ensiling cereal greenfeed to try to procure enough feed.  ‎Dugout water levels low; some producers are hauling and pumping water for livestock consumption.
