Crop Report: Issue 13, July 27, 2015

 
 

Weekly Provincial Summary

  • Generally, the condition of most crop types is rated as good in Manitoba.  The continuing hot and humid weather conditions are advancing crops quickly.
  • Harvest of winter wheat and fall rye is expected to start this week. To date, low disease pressure is noted in the winter cereal crops.
  • Thunderstorms of varying severity resulted in excess moisture, hail activity and lodging of crops across some areas of Manitoba. 

 

Southwest Region

Scattered, isolated showers were reported throughout much of the Southwest Region. Precipitation accumulations varied significantly, with 30 to 35 mm in the Deloraine and Carberry areas, and 5 to 20 mm in the remainder of the region. Some hail activity was also reported.
 
In general, the past week produced beneficial growing conditions in the Southwest Region. Crop conditions are rated as good. Approximately 90% of the winter cereals are at the hard dough stage; low fusarium levels are reported. Ergot levels are also reported very low in fall rye. All spring cereals are maturing fast due to hot and humid weather conditions. Most fields are at soft to firm dough stage. Some leaf diseases and fusarium head blight can be seen in spring wheat but levels are very low. Lodging is very visible in some fields.
 
The later seeded canola crop is advancing rapidly due to favourable weather conditions. About 75% of the canola crop is in late flower to early pod stage, and 25% is podding. Most canola acres received fungicide for sclerotinia. No major insect activity is noted.
 
Field peas are podding, and in some cases are near to maturity, especially in moisture stress conditions. Aphids are reported in some fields but there is no harm to the crop at this stage of development; natural enemies are controlling populations as well. Most flax fields have finished flowering and are starting pod development.
 
Soybeans continue to respond well to the excellent growing conditions and have experienced rapid growth. Most soybeans are in the R3 (pod initiation) stage of development.  Sunflowers are flowering. A few lygus bugs are evident and some control measures have been undertaken.
 
Hay field and pasture conditions across the Southwest Region are variable, due to a range in excess moisture to extended dry conditions. Sporadic moisture over the past week helped with pasture growth and hay regrowth in the drier areas of the region. First cut hay is mostly complete and native hay is beginning to be harvested. Generally, yields are below average. Greenfeed cereals are nearing harvest stage. Dugout levels remain steady at 80% full on average. 

 

Northwest Region

Unsettled weather over the past week caused isolated thunderstorms in some parts of the Northwest Region. Soil moisture conditions range from dry in some parts of the Swan Valley to adequate in most other areas of the region.

 
Generally, cereal crops in the Northwest Region are reported to be in good to fair condition. Symptoms of dry moisture conditions are evident in some wheat fields, especially in the Swan River Valley where plants in areas of some fields are stunted and maturing rapidly. Cereal crops in The Pas are reported to be in excellent condition.  Approximately 90% of the winter wheat crop is in the dough stage of growth and about 5% of that crop is ripe. About 70% of the spring wheat crop is at the milk stage of growth with the remaining 30% in the dough stage.
 
Canola ranges from very good to poor, mostly because of earlier dry conditions causing poor and non uniform emergence of some reseeded fields. However, canola improved significantly over the week as the crop continues to develop rapidly. Approximately 80% of the canola crop is at some stage of bloom while about 20% is podded.
 
Approximately 90% of the corn crop is in the V6 to V13 stage of growth, and 70% of the soybean crop is blooming and 30% is podded. About 85% of the flax crop is flowering with the remaining 15% at the boll stage of growth.
 
Weed control looks adequate for most of the crops in the region, but wild oat escapes have appeared in some wheat fields. Most fungicide applications are complete on those fields requiring treatment.
 
Insect activity throughout the region is relatively low but producers are continuing to scout their crops for the presence of any unwanted insect activity.
 
Haying was generally in full swing, although localized showers did stall some haying operations.  Producers are putting up hay in good condition due to little to no rain, but quality may be impacted by the lateness of first cut. Yields are average to below average in most parts of the North Parkland and Valleys North. Pastures are average with adequate moisture and water supplies are adequate.
 

Central Region

Warm and humid weather conditions in the Central Region, allowing for rapid crop growth. Most areas have adequate moisture. Unsettled weather conditions later in the week and on the weekend resulted in heavy thundershowers, with some reports of hail. Most of the region received rainfall with amounts ranging from 5 to 125 mm. Rain and winds resulted in many lodged cereal crops. The heavy rainfall in some areas also led to field runoff and filling up of ditches temporarily.

Harvest of winter wheat and fall rye is expected to start this week with many fields at maturity. Harvest management products have been applied on many fields in preparation for harvest. Spring cereal crops throughout the region look good and some of the lodged cereal fields have recovered somewhat. Most fungicide applications are complete. Fusarium head blight levels appear to be low in the wheat crop.
 
There is a wide range in canola development due to the varied seeding dates. Reseeded canola fields are still flowering but many of the most advanced fields are finishing flowering and pods are filling.
 
Sunflowers are growing well and are starting to flower. Monitoring continues for insects, and staging is being done for fungicide application. Sunflower beetle numbers are low. Corn development ranges from tasseling to finishing silking. Soybeans are flowering and pods are developing on the lower parts of the plants. Excellent growth is reported in majority of soybean fields. Some fungicide applications are being made. There are reports of soybean aphids in the Winkler area, but populations are well below economic levels.
 
Edible beans are flowering, and fungicide applications continue as environmental conditions are conducive for white mould. Bacterial blight is reported in cranberry and kidney types. With recent heavy rains, some fields are showing stress symptoms of yellowing. Pea fields are mostly done flowering, with the majority podded. Irrigation continues in potato and vegetable crops in the Portage area.
 
Diamondback moth and bertha armyworm trap counts are average to low for the season indicating a low to moderate risk of infestation from these canola pests. Lygus bugs are being found in canola fields, but numbers are below threshold levels. Grasshopper nymphs are present at field edges and on roadsides, at average populations to date. True armyworms are found in cereal fields, particularly in lodged areas. Most fields do not have sufficient numbers to warrant control. Corn borer numbers are reported to be approaching threshold levels in the Portage area.
 
Alfalfa second cut is underway but the harvest is challenging given the recent rainfall events and high humidity. Hay yields are expected to be near normal. Pastures are looking good with abundant rain and warmer temperatures. Alfalfa weevil damage is visible in some of the alfalfa/grass fields.

 

Eastern Region

In the Eastern Region, warm temperatures and high humidity levels continued along with almost daily isolated rainfall events or thunderstorms of varying severity. Rainfall accumulations ranged from trace amounts to over 55 mm, with large accumulations occurring as a part of sudden thunderstorms. Rainfall amounts were generally higher in central and southern districts. Across the Eastern Region, fields show increasing evidence of standing water and areas where crop is drowned out. Some more crop lodging, particularly in cereals, also occurred. Soil moisture conditions on crop land are rated as adequate to surplus. There is increasing concern about excess moisture and producers are looking for sunny, dry weather in the coming weeks.

Spring cereal crops are in the late milk to soft and hard dough growth stages. Some early seeded fields are in late hard dough. Winter wheat is at hard dough to ripe. Canola is podding and filling. Soybeans range from late R2 to R3. Sunflowers range from R4 to R5 stages with corn at tasseling to silking.

To date, insect concerns remain limited. Reports of Phytophthora root rot in soybeans increased significantly over the last week. Preharvest glyphosate applications began on winter cereals over the weekend and some fungicide applications on sunflowers to prevent sclerotinia head rot also occurred.

Across the region, the majority of hay and pasture lands are in good condition. Haying resumed as producers were stopped due to rainfall. For first cut hay, it is estimated that 25% is standing, 15% is cut and 60% is baled or put up as silage. Quality is rated as good. Pastures are doing well. Dugouts are full of water and availability of livestock water is adequate. 

 

Interlake Region

Isolated thunderstorms went through the Interlake Region last week resulting in excess moisture, lodged crops and reducing quality of cut hay. Rainfall amounts ranged from 20 to 30 mm, to some areas receiving 40 to 50 mm. Moisture issues are a concern as producers are starting to get ready to swath and combine their forage seed grasses and winter wheat crops.
 
South Interlake producers started preharvest applications of glyphosate in winter wheat fields. Armyworm damage in winter cereals is reported as producers are noticing the lack of flag leaves and clipped seed heads. Spring cereals continue to mature and are looking good considering the recent weather events. In areas, spring cereal crops lodged but hopefully with improved weather conditions the crops will recover to a certain degree. Canola staging varies throughout the region, with some fields at 60 to 70% bloom and other fields 100% podded. Soybean fields continue to flower (R1) and pod (R3). Field peas are in the pod filling stage. Corn throughout the region has started to tassel.
 
Rain throughout the Interlake Region was welcomed in areas but not in others, hampering haying efforts. Hay yields are quite variable. Some alfalfa weevil damage is evident in second growth alfalfa; alfalfa seed growers are spraying insecticide for control. Cutting of annual greenfeed crops is just starting. Silage corn looks good. Pastures are holding out well.
