Crop Report – for Jul. 28, 2011


Rainfall over the past week varied from 10 to 50 mm. Good growing conditions helped crops advance and several crops have improved over the past week. Cereal crops in the Southwest Region are in the heading stage and late-seeded crops have tillered and are going into the flag-leaf stage.

Late-seeded greenfeed is in the three-to four-leaf stage. Early-seeded canola is going out of bloom and podding. Some of these acres are showing the effects of the earlier wet conditions and recent heat, including thin stands, shorter plant height, and decreased flowering time; yields will likely be impacted. Winter wheat and fall rye are maturing quickly and producers could be harvesting in two to three weeks depending on the weather.

Crops look to average to above average. Several producers continue to clean up wet and flooded acres. Haying continues. On the land that is dry enough to travel on, both yield and quality have been average to above average. However, the overall harvested amount of hay in the region will be below average since many areas either remain flooded or inaccessible.


Rain and thunderstorms were general towards the end of last week. Precipitation amounts ranged from 16 to 70 mm with local reports up to 100 mm and light hail in the Roblin area. Crops in all areas of the region benefited from the rain.

Early in the week hot temperatures caused some concern for heat blast on flowering canola. Wheat is heading, flowering and 40 per cent is into early seed development stages.

Variable germination and development of greenfeed acres seeded late into dry soils has improved with the recent rain. Winter wheat is maturing and buckwheat is advanced into blooming stages.

Bertha armyworm trap counts are at moderate risk through the Durban area with San Clara counts increasing more than other areas which remain at low levels. Overall disease levels in all areas continue to be lower than average.

First-cut haying operations are more than 80 per cent complete under dry conditions. The rain has delayed remaining harvest; some forage had been cut and weathering is reducing quality. Overall yields and quality are average or better. Production potentials remain poor for much of the flood impacted low-lying or poorly drained native forage and pasture lands adjacent to lakes Manitoba, Winnipegosis and Dauphin.


Sporadic rain mid-week hit the northern part of Central Region with Gladstone receiving 75 mm of precipitation while a few miles away only received 12 mm.

Warm temperatures have advanced crops and have led to heat and moisture stress symptoms in some crops. Areas with excess moisture are still showing less advanced crop development and plant stresses.

Winter wheat fields are being sprayed with pre-harvest applications. Early-seeded canola is finishing flower and podded well while late-seeded canola is beginning to flower. Corn tassels are showing on a number of fields. Edible beans and soybeans are starting to pod.

Processing potatoes are being irrigated and a number of fields are in full flower. Greenfeed seeding finished this past week. Fungicide applications have slowed given the drier weather conditions.

Edible bean fields showing good growth have been sprayed for white mould control prior to row closure. Diamondback larvae are feeding on canola leaves with minimal damage. Bertha armyworm trap counts continue to have low numbers. Wheat and barley fields in different areas have damage from thrips and some have been sprayed for control. Soybean aphids have been noted in most fields at low numbers. Greenclover worms in soybeans are eating small holes in leaves. Dairy-quality hay was taken off last week with average yields and good quality. Grass hay is almost complete with good yields reported to date. Haying was slowed during the week as high humidity slowed drying time. Recent warm and dry temperatures impacted pastures and rain is needed to promote growth.


Weather in the Eastern Region was sunny and very warm. Some isolated and widely dispersed rainfall events did occur. Overall soil moisture was rated as ideal to full throughout the region. The earliest-seeded spring wheat is in the soft-dough stage with the rest of the crop being somewhere in the milk to soft-dough stage.

Fungicide applications for fusarium head blight are near completion. Pre-harvest glyphosate applications began late last week and some producers did try a small amount of harvesting over the weekend; however, the crop was tough with some immature kernels.

Visually, heads infected with fusarium head blight are not as easy to find as in the past few years. In some cases damaged kernels were mistaken for damage from root-related disease and moisture stress. The most advanced canola crop has completed flowering and continues pod filling. Soft green seeds are evident. The late-seeded crop is in some stage of flowering. Fungicide applications have wrapped up. Some flower blasting has been observed but crop that has completed flowering did not appear to have dramatically lost yield potential.

Some spraying for diamondback moth larvae has occurred. Early seeded flax crops have completed flowering and are filling.

Soybean crops are flowering and are beginning pod formation. Corn is entering R1 and has begun silking. Sunflowers are in the process of forming heads. Hayfield condition ranges from fair to good across the region. First-cut haying is 75 per cent done. Yields in southern areas of the region were reported as two tons DM per acre for alfalfa and 1.75 tons per acre for alfalfa/ grass hay. In northern areas hay yields have been reported as about 80 per cent of normal expected yields. Some concern has been expressed about low yield potential for the second cut primarily attributed to low rainfall levels. Pasture land conditions are rated as good but very high levels of bull flies pressuring livestock are noted.


The North Interlake received heavy rainshowers on Wednesday with amounts ranging from five to 55 mm. The Riverton area received the most precipitation with unconfirmed reports of 100 mm. Rainfall would be welcomed in the south as crops move toward maturity.

Early-seeded canola is finished flowering while late-seeded crops are just beginning to flower. Sclerotinia control is taking place on late-seeded crops. Early-seeded spring wheat is headed and applications for fusarium head blight have begun. Late-seeded crops are variable. Dry, lumpy seed beds, followed by hot, dry conditions have left many of these crops with poor emergence and generally poor stands.

However, many late broadcast- seeded canola fields are looking good. Haying progress has been good over the last seven to 10 days with only slight delays due to scattered showers. Producers are commenting that many acres that were too wet to harvest in the past few summers are passable this year. Bulrushes, cattails, and willows are being removed with hopes that grass species will return in these areas.

Some of these fields will undergo forage restoration in coming years if weather conditions permit. Pasture conditions have improved with regards to drier lowlands. Higher pastures are mostly in need of rain. Biting insects are still pressuring cattle during the day.
