It didn’t just rain, it poured — causing floods

MAFRI crop report for June 24, 2013

Weekly Provincial Summary

Many areas of Manitoba received significant amounts of rainfall over the past several days. Impact to crops is being assessed and will depend on the stage of crop development and duration of the excessive moisture conditions.

Earlier in the week, crops showed rapid development given the warmer weather conditions.

Producers made excellent progress with herbicide applications; progress by crop type ranges from 80 to 100 per cent complete.

First-cut haying operations continue with average yields.

Southwest Region

The Southwest Region experienced moderate to heavy rainfall over last week with amounts ranging from 30 to 200 mm. The heaviest amounts fell in the Pipestone and Reston area where localized overland flooding was experienced. Much of the remainder of the region received 50 to 80 mm.

Weed control measures continued and are nearing completion.

Insect activity continued to intensify early last week with flea beetle feeding in canola still requiring additional control measures. Cutworm injury also increased over the past week with most reports of activity coming from northern areas of Birtle, Rossburn, Strathclair, Hamiota and Elphinstone.

Pasture and hay growth continued to improve over the past week with most forages now entering the reproductive stages of development. Water levels in sloughs and dugouts are now 90 to 100 per cent.

Northwest Region

By the week’s end, all areas of the region were affected by rains and heavy thunderstorms with precipitation amounts from 75 to 125 mm. Producers in the Westlake area from Eddystone to Meadow to Portage report receiving up to 190 mm of rain. In the more affected sectors, flooding and some damage to infrastructure and roads is limiting access to livestock, pasture and fields.

Crop development, stand consistency and crop conditions have been good.

With the recent rainfall, some localized water ponding in crops, forages and pastures is now evident in all areas of the region and particularly in the low-lying areas.

Herbicide applications are 85 per cent completed overall.

Canola insect trap counts continue to be very low. Low numbers of European Skipper larvae were observed in a few mixed hay fields.

Condition of forage and pasture land are rated as good to fair; yields are expected to be average or below average. Moisture supply is adequate to surplus and some warmer temperatures are needed to increase grass yields. Hay harvest is very limited to date; some initial cuts just before the rain were not baled and remain in the wet field conditions. Dugout water levels are full to adequate.

Central Region

Rain fell throughout the region with some areas receiving significant amounts over the weekend. Altona area saw 12 to 20 mm, Headingley 10 to 125 mm, Mather/Cartwright 100 mm, and Plumas 65 to 75 mm.

Some acres remain unseeded due to excess moisture.

Windy conditions delayed herbicide applications.

Stands of many crops are uneven. Some canola was reseeded due to poor crop stands, further compromised by heavy flea beetle pressure.

Corn crops are improving in colour and growth has improved greatly. Soybeans range from unifoliate through to early third-trifoliate stage. Most fields have had one application of glyphosate.

Canola ranges from just emerging to bolting and early flower. Flea beetle feeding was a concern in much of the region. Earliest-seeded fields had the most pressure; some fields seem to be bolting early due to combined stresses.

Fall rye is headed and winter wheat is entering the flag leaf to early-heading stage. Most fields have variable crop staging and timing for fusarium head blight suppression fungicide application, if necessary, will be difficult.

Cutworms are reported in a few corn and broadleaf crops.

Hay fields were slow to progress with average to cooler temperatures but growth is improving. Grasses in pastures are starting to head out. Most pastures are growing rapidly.

Eastern Region

Rainfall amounts from 12 to 25 mm fell this past weekend in the Eastern Region. Cropland moisture levels across the region are rated at 90 per cent adequate and 10 per cent short.

Crops showed rapid development last week.

First-pass or single-pass herbicide applications are 90 to 95 per cent complete. Herbicide performance in general has been satisfactory with no major concerns. Spraying for fusarium head blight will start as soon as the plants start to flower. Foliar fungicide applications on annual cereals could start by weekend.

Leafhoppers are being reported in some soybean fields but no defoliation is evident. Some lygus bugs were also found but no concerns to date. In cereal fields, root rots and wireworms are impacting stands.

Hay conditions in the region are rated as 80 per cent good.

Interlake Region

Isolated thundershowers through the week brought accumulations of 20 to 40 mm to some localized areas across the Interlake Region. Moosehorn to Gypsumville were the hardest hit with water ponding in most fields. General showers on Sunday accumulated to 20 mm across the region. The Woodlands area received 45 mm from this system.

Herbicide application continues. Showers encouraged weed emergence in drier areas making additional herbicide applications necessary for some producers. Winter wheat is beginning to head out.

Alfalfa is in early-bloom stage. Seed producers are staging the crop for insecticide application prior to leafcutter bee turnout. Timothy seed fields are at the early-heading stage.

First-cut haying operations continue with generally good yields. Pasture conditions are average.
