Crop Report: Issue 11, July 13, 2015


Weekly Provincial Summary

  •  Hot and humid weather conditions resulted in rapid crop growth across most of Manitoba.
  • Generally, condition of most crop types is rated as good, although variability is noted across the province.
  • Majority of acres and crop types have entered the flowering and grain fill stages of development.
  • Although many areas did receive much needed rainfall, precipitation would still be welcomed in some areas.
  • Good weather conditions permitted producers to make good progress with haying operations.  Yields are average to below average with good quality being reported.


Southwest Region

In the Southwest Region, warm and humid weather conditions prevailed most of the week. Majority of crops in the region are rated in good condition. However, moisture is becoming a limiting factor in some areas of the region. Scattered showers over the weekend brought moderate amounts of precipitation. Killarney, Inglis, Birtle, Erickson and north of Neepawa areas received 35 to 40 mm, and Carberry area reports 65 mm of rain. Pea-sized hail was also reported in some areas and resulted in localized crop damage.

Winter crops are in the grain fill stages of development and starting to turn. Most acres are rated as good with no major issues. Spring cereal crops continue to develop with more disease starting to develop on the flag leaf. Most producers have applied fungicide. There are reports of cereal armyworm in the southwest corner of the region.

Early seeded canola crops are in full flower, with later and reseeded fields starting to bolt. Some producers are looking at spraying for disease management in the later seeded crop. Bertha armyworm counts are a little higher from the previous weeks but still below the economic threshold level.

Sunflowers are in the early bud stage. No major issues are reported and the crop continues to grow rapidly with the excellent growing conditions. Corn is also benefiting from the hot temperatures. Soybeans are at R2 stage of growth, which is full bloom. Some fields are showing moisture deficiency. Flax is flowering. Peas are flowering, with 20 to 30% podding.

Producers continue with first cut haying operations and yields are average to below average. Recent rains will impact hay quality if crop was cut and not baled. Pastures have been impacted by the heat and lack of rain, and in some areas overgrazing. Dugouts are 70 to 75% full.


Northwest Region

Scattered showers throughout most of the Northwest Region midweek and again over the weekend resulted in rainfall amounts ranging from 12 to 64 mm in the Roblin and Swan River areas. The rain was very welcome and will help for grain fill, as well as the late seeded and reseeded canola. Warm temperatures have also advanced crops along rapidly. Overall, crops are in good to fair condition in the Northwest Region; The Pas is the only area reporting some wheat and canola in excellent condition.

For winter wheat, 75% of the crop is in the dough stage. Maturity on spring cereal crops ranges with 40 to 60% heading out and 20 to 50% in the milk stage. Cereal growth in some fields is stunted due to dry conditions and moisture is needed for grain fill.

Canola progressed rapidly this week with 90% flowering, although some late and reseeded fields are still in the rosette/bolting stage. Overall, canola ranges from good to fair condition, mostly because of dry conditions.

Corn progressed rapidly with the warm temperatures and is also in good to fair condition.  Approximately 10% of acres are in the V1 to V5 stages, with the remaining 90% of acres V6 to V13. Soybeans are generally in good condition with 40 to 90% of acres flowering, some fields are podded. Peas and flax are in full flower throughout the region.

Some spraying for Fusarium head blight and sclerotinia is reported. Due to dry conditions, disease pressure is generally low.

Much needed rains for pastures and second cut hay fields were received over the past weekend in areas of the North Parkland and Valleys North. Haying is progressing with average to below average yields. Water supplies are adequate, although some dugout water levels are reported as low.


Central Region

Warm and humid weather conditions continued for much of the week, allowing for rapid crop growth in the Central Region. Most areas have adequate moisture, and heavy morning dews are common. Unsettled conditions over the weekend resulted in scattered thundershowers. Rainfall amounts ranged significantly, from as little as 10 mm to as much as 40 mm. Most areas have adequate moisture for excellent growing conditions but variability across the region exists; some areas are looking for more rain, while others have standing water in low lying areas and ditches are running.

Cereal crops throughout the region are rated as good, although many are lodged. Some fields have recovered however. Weather conditions are conducive for disease development in much of the region, and fungicide applications continue as crops come in to stage and where conditions warrant treatment. Winter wheat and fall rye are starting to turn as grain fill continues.

There is a wide range in canola development due to the varied seeding dates. The later seeded fields will soon flower. Fungicide applications for the majority of canola fields in the eastern part of the region range are complete; the later reseeded canola will see application shortly, where moisture conditions warrant. Many of the most advanced fields are finishing flowering.

Corn has recovered from lodging and is growing rapidly. Sunflowers are growing well, with buds forming. Soybeans are flowering and nodulating well. Most fields have grown through the yellowing of iron chlorosis deficiency. Wrinkling of leaves is evident due to the recent rapid growth. Edible beans are flowering and fungicide applications continue. With recent heavy rains some fields are showing stress symptoms of yellowing. Overall most fields look good. Pea fields are flowering. Potato and vegetable crops are being irrigated in the Portage area.

Diamondback moth and bertha armyworm trap counts are average to low. Numbers are slowly increasing, with higher numbers in western parts of the region. Grasshopper nymphs are present at field edges and on roadsides, at average populations to date. Some hot spots from last season have seen control measures taken. Some armyworms were found in cereal fields, but not in sufficient numbers to warrant control, and most seem to be at quite an advanced stage. Ongoing monitoring will continue.

Alfalfa grass first cut continues as weather permits. Baling progress is slow due to high humidity and rains; curing is taking more time. This week’s weather forecast may continue to delay haying operations. Hay yields are average to below average depending on factors including frost, winter injury, and drier conditions. Pasture growth is good with the abundant moisture and warmer temperatures. Alfalfa weevil damage is visible in some of the alfalfa/grass fields. Rain has replenished dugouts and water supplies are considered adequate.


Eastern Region

Warm temperatures accompanied by high humidity levels and generally sunny skies contributed to good growing conditions last week in the Eastern Region. Localized thunderstorms and rainfall events of varying severity occurred throughout last week and over the weekend with accumulations ranging from of 10 to 100 mm. Rainfall amounts were generally higher in central and southern districts, and fields in these areas show more evidence of standing water and areas where crop is being drowned out. In these areas, some further crop lodging was noted as well as some recovery from lodged crop conditions which had occurred in the previous week. Soil moisture conditions on crop land are rated as mostly adequate to surplus with most of the surplus situations in central and southern districts.

Development of spring cereal crops range from the late flowering to milk stage. Winter wheat is in soft dough. Canola development is ranging from mid-flower to pod fill. Soybeans range from V3 to V5 trifoliate leaf stages to late R1, nearing R2. Sunflowers are in R1 with corn ranging from V8 to V12.

Post-emergent herbicide applications are almost complete with mostly late applications of glyphosate to soybeans remaining. Fusarium head blight fungicide applications to spring cereals are almost complete. Fungicide applications for sclerotinia in canola are also almost complete. In southern and central districts, more aerial application occurred because of field conditions.

Reports of armyworms in cereals, forage seed crops, canola and soybeans were received with limited insecticide application occurring. There are also reports of diamondback larvae in canola with very limited spraying occurring. Threshold levels of sunflower rust were found in the Beausejour area and fungicide applications are occurring. Rhizoctonia root rot in some soybean fields is noted.

Across the region, the majority of hay and pasture lands are in good condition. For first cut hay, it is estimated that 40% is standing, 30% is cut and 30% is baled or put up as silage. Quality is rated as good. The warm weather last week was welcomed as producers resumed haying towards the end of the week, flipping swaths to dry and bale. Pastures are generally in good condition. Availability of livestock water is adequate.


Interlake Region

Hot temperatures and humidity were experienced throughout the Interlake Region. Scattered showers occurred throughout the week leaving trace amounts of precipitation. In the Arborg, Riverton and Arnes area, the lack of precipitation was welcomed as low areas of the fields still have standing water. Reports of 20 to 30 mm of precipitation occurred during the weekend in the Moosehorn and Ashern region, which was welcomed considering the reduced precipitation throughout the growing season.

Fungicide application on spring cereals is still on-going, with the majority of acres being sprayed last week. Winter wheat continues to mature, spring wheat and barley is at or nearing the end of flowering, and oats crops are still being sprayed at the flag leaf stage on later seeded fields. Some canola fields in the South Interlake region are almost finished flowering. The hot temperatures are shortening the flowering period of the canola crops.

Soybean crop staging is R1, and corn V7 to V10. Armyworms are being found in fields, with minor damages to the crops reported to date. Forage grass seed fields such as timothy are finished flowering. Alfalfa seed fields continue to bloom as leaf cutter bees continue to pollinate these fields.

Scattered showers this past week were of benefit to hay fields and pastures. Conditions continue to vary considerably throughout the Interlake Region, with the east side being moist to very wet and the west side needing rain. The hot, dry conditions are allowing for hay to dry and cure however. Well managed pastures are showing resiliency to the drier conditions. Adequate water for livestock is noted.
