Weekly Provincial Summary
Crop growth continues to be slowed by the cooler temperatures and the frequent rainfall in some areas of Manitoba. The moderate temperatures will benefit flowering and grain filling of many crop types. However, a return to warmer temperatures will help advance the warm, season crops such as grain corn, soybeans, edible beans and sunflowers.
Winter wheat harvest has started in Manitoba with preliminary reports of yields ranging from 60 to 80 bushels per acre, with good quality and protein levels.
Rainfall varied with accumulations of 10 to 50 mm. Temperatures remain cooler than normal. Moisture levels remain above normal and there are still reports of overland flooding.
Several cereal fields are starting to show disease pressure; fusarium head blight can be found in almost all wheat fields and the severity varies according to variety and fungicide application.
Cool, moist conditions allow canola to flower for several weeks, increasing yield potential. Sclerotinia is evident in several fields in the region. Some producers in the southeast part of the region are reporting high numbers of army worms.
Several producers have been silaging over the past week and cereal silage is yielding average to above average.
Temperatures were moderate to below seasonal, with occasional overnight lows of 6 C to 8 C.
Winter wheat is ripening with harvest anticipated shortly. Perennial ryegrass is being swathed.
Symptoms of fusarium head blight and sclerotinia is reported across the region. Grasshopper activity is low and generally on lighter pastures, soils and ridges.
Haying conditions improved the past week. Overall, the tame forage acres are approximately 75 per cent baled and 25 per cent has been cut; generally, average yields are reported. Forage quality is variable, rating from good to poor. The native hay harvest has begun in the accessible drier fields.
The Central Region saw cooler temperatures, along with scattered showers. Eastern parts of the region report 15 to 25 mm of rain, while western areas received 20 to 40 mm.
A few winter wheat fields have been harvested. Fungicide applications for sclerotinia management continue on the later-seeded canola fields, where staging and moisture conditions warrant. More blackleg leaf lesions were reported throughout the region.
Bacterial blight is evident in most soybean fields and some edible bean fields, as is sunburn. Root rots are evident in many soybean fields.
Late-germinating wild oats are now evident in some winter wheat and spring wheat crops. Redroot pigweed and kochia are also evident in canola and some cereal crops. Volunteer crops, including canola, soybeans and corn, are becoming more noticeable.
Diamondback larvae are found in canola with no significant damage at this point. Higher bertha army worm trap counts are seen, with numbers in the low to uncertain risk range. Trap counts are starting to decline. Grasshopper activity continues in much of the region, although many areas report a decline in numbers.
Rainfall amounts in the Eastern Region ranged from five to 16 mm this past week.
Crops in general are doing well.
Concerns about grasshoppers, green cloverworm, army worms and other defoliators continue in cereal, canola and soybean fields. Canola concerns are moving from leaf damage to pod damage issues. No soybean aphid reports to date; some diamondback larvae have been found and one field above threshold was sprayed.
Root rots continue to be a problem in soybeans with lab reports indicating either fusarium wilt or phytophthora root rot.
First-cut haying is finishing up with progress at five per cent cut and 90 per cent baled or silage. Harvest of native grasses is well underway and roughly 80 per cent complete. Average per cent of normal yields for both first and second cut are reported as: alfalfa 95 per cent, grass/alfalfa 95 per cent, other tame hay 95 per cent and wild hay 75 per cent.
Pasture conditions in the region are rated as 50 to 75 per cent good, 25 per cent fair and zero to 25 per cent poor in the region. Livestock water supply is rated at 100 per cent adequate.
Precipitation amounts ranging from four to 30 mm was experienced. Cool daytime temperatures delayed crop ripening in such crops as winter wheat and other spring cereals.
Winter wheat harvest on select fields in North and South Interlake have started. Early reports indicate the yields are less than expected but quality is good. Canola continues to ripen slowly with the chance that some fields in South Interlake may be cut towards the end of the week.
Second-cut hay began with reports of 0.5 to one ton per acre yield. Native hay is still being cut and baled with yields ranging from one to 1.5 ton per acre. Pasture and dugout conditions are good.
