Manitoba Moisture Conditions Remain Variable

Manitoba moisture conditions continued to vary widely between regions this past week, according to the latest weekly crop report released Wednesday. 

Variable rainfall was recorded during the eight-day reporting period, with isolated thunderstorms bringing precipitation to parts of the Southwest, Central and Eastern regions. Saint Labre received the largest amount at 48.1 millimetres, followed by Dand at 35.7 mm, while the Interlake received little or no rain. 

Since May 1, portions of the Northwest and Interlake have accumulated about 300 mm of precipitation. Seasonal totals remain above normal throughout the Northwest and across large areas of the Interlake, with parts of the Central and Southwest regions also wetter than average. However, localized areas of the Southwest, Central and Eastern regions have received less than 80% of normal precipitation, the report said. 

Winter wheat and fall rye are generally in the hard-dough stage, with some fields already ripe or harvested. Most spring cereals have reached the soft- to hard-dough stages, and desiccation of barley, oats and early wheat is beginning in several regions. 

Canola development has advanced rapidly, with early crops completing flowering and lower pods beginning to change colour. Later-seeded and moisture-affected fields are still flowering. Heat during bloom has raised concerns about pod set in parts of the Central and Eastern regions. 

Soybeans are generally between the R3 and R5 stages, while peas continue through pod development and early colour change. Corn has also progressed quickly and ranges from tasseling and silking to pollination complete and the blister stage. 

Southwest 

• Temperatures reached about 30 degrees C, while scattered showers produced 25–35 mm along a narrow path from Reston to Hartney and only 1–4 mm elsewhere. 

• Crops remain in generally good condition, with strong yield potential, although wet spots, lodging and minor hail damage are visible. 

• Winter wheat is at hard dough and rye is ripe; spring cereals are approaching maturity, with some fusarium head blight reported. 

• Soybeans are at R3 to R4 and look healthy, while peas are moving toward colour change with relatively low disease pressure. 

• Canola ranges from late flowering to mid-pod development, with early fields beginning seed colour change. 

Northwest 

• Hot weather helped crops advance, while soils and damaged roads continued to dry following earlier flooding. 

• Field access remains difficult in some areas, although roads are gradually becoming passable. 

• Winter cereals are at hard dough, while advanced spring cereals have reached late milk or early soft dough. 

• Peas are moving through R5 toward R6, and advanced soybeans have reached R3. 

• Most canola is nearing the end of flowering, although late-seeded and water-stressed fields remain behind. 

Central 

• High temperatures accelerated maturity, with fall rye harvest beginning in southern areas and cereal desiccation underway. 

• Early wheat is at hard dough, while barley and oat fields are already being desiccated. 

• Soybeans are mostly at R4 to R5, although waterlogged areas remain thin, yellow and poor. 

• Corn is primarily at the blister stage and is generally in good condition. 

• Early canola is changing colour, but intense heat during flowering may have reduced pod set. 

Eastern 

• Rainfall ranged from 0.3 to 48.1 mm, providing welcome moisture for corn and soybeans. 

• Winter cereals are at hard dough, with some fields harvested near Lac du Bonnet and desiccation beginning elsewhere. 

• Corn is tasseling or silking, with many cobs about two-thirds fertilized and kernels entering the blister stage. 

• Soybeans are generally at R4 and look good, although moisture stress, weeds and localized grasshopper damage are concerns. 

• Early canola is showing seed colour change, while later fields finish flowering; poor pod set from earlier heat remains a yield risk. 

Interlake 

• Warm, humid conditions prevailed, with temperatures of 30–34 C and little or no rainfall. 

• Some saturated fields still need dry weather, while drier fields would benefit from rain to support grain filling. 

• Winter and spring cereals are mostly rated good to excellent as they advance toward maturity. 

• Corn and soybeans are developing well, although saturated areas show yellowing, uneven stands and delayed growth. 

• Canola conditions are highly variable, while disease and weed pressure could increase under continued heat and moisture.
