Severe storms, flooding and hail leave Manitoba farmers assessing crop losses while disease, weed control and yield concerns continue to emerge.
Manitoba farmers are navigating one of the most challenging stretches of the 2026 growing season as excessive rainfall, flooding and damaging hailstorms have affected crop development across large portions of the province.
According to weekly crop and weather reports compiled by Manitoba Agriculture, widespread precipitation has saturated fields, overwhelmed drainage systems and caused localized crop losses. While many crops continue to hold strong yield potential, producers in several regions are dealing with significant setbacks caused by standing water, lodging, delayed field operations and hail damage.
The most severe weather impacts were reported in southeastern and northwestern Manitoba, although virtually every agricultural region received substantial rainfall during the reporting period.
Large Hail Causes Localized Crop Damage
Several communities experienced severe hail events capable of causing significant yield reductions.
Major hail was reported near Cromer, Dand, Boissevain, Killarney, Wawanesa and north of Hartney. Minor hail, roughly the size of a loonie, was reported around Reston and Brandon. The most severe storms occurred near Boissevain, where golf ball-sized hail was recorded, and near Killarney, where baseball-sized hail damaged crops.
Moderate lodging in cereal crops has also been observed near Melita, creating additional concerns as crops move into important reproductive growth stages.
Despite the damage, Manitoba Agriculture reports that much of the Southwest Region continues to show strong yield potential. However, some flooded areas are not expected to recover, resulting in permanent crop losses.
Flooding Overwhelms Northwest Manitoba
The Northwest Region experienced some of the province's most significant weather-related impacts after an intense storm system delivered heavy rainfall early in the week.
Rain began Monday and persisted into Tuesday, producing enough precipitation to overwhelm ditches, drains and river systems across the region. The result was widespread overland flooding, damage to infrastructure and waterlogged farmland.
The Swan Valley area, which had already been affected by previous flooding, was hit particularly hard for a second time.
Although water levels have begun to recede, many fields remain flooded or damaged, and producers continue to assess the full extent of crop and infrastructure losses.
Wet Conditions Delaying Field Operations
Persistent rainfall is creating additional challenges beyond direct crop damage.
While some producers managed to complete herbicide applications during favourable weather windows, many others have been unable to access fields because of excess soil moisture, rain and strong winds.
Missed herbicide timing could increase weed pressure later in the season, particularly in regions where fields have remained saturated for extended periods.
Across Manitoba's eastern growing areas, crops are also showing signs of stress associated with excess moisture. Spring cereals range from tillering to flag leaf stages, with plants in saturated areas exhibiting reduced vigour.
Canola growth varies widely, from four-leaf crops to fields already entering early flowering. Some canola fields affected by prolonged wetness are becoming thin and beginning to stress bolt, while herbicide applications remain a challenge in many northeastern locations.
Soybean fields are generally at the second to fourth trifoliate stage, although some stands are displaying signs of iron deficiency chlorosis and moisture-related stress.
Strong Yield Potential Remains for Many Crops
Despite weather-related setbacks, Manitoba's major field crops continue to show encouraging development overall.
Winter wheat and fall rye have entered flowering and are described as highly promising, with strong yield potential across much of the province. Fungicide applications have largely been completed as growers focus on protecting crop quality and yields.
Spring cereals are progressing from tillering and stem elongation into early heading, with many producers now evaluating fungicide strategies for fusarium head blight management.
Disease symptoms, including suspected tar spot, have been observed in some cereal fields, reinforcing the importance of crop scouting as canopies continue to develop.
Corn development remains generally positive, with most fields reaching the V6 to V8 growth stages. However, fields affected by excess moisture are showing uneven growth and nutrient stress symptoms.
Among oilseeds, canola is advancing rapidly, ranging from six-leaf stages to flowering. Some of the earliest fields have already reached 40 to 50 per cent bloom.
Producers are closely monitoring cabbage seed pod weevil populations after significant feeding activity was observed in certain canola fields. (Read the article: Watch for Seedpod Weevils.)
Soybeans, sunflowers and peas are also progressing steadily. Although many soybean fields have experienced temporary yellowing due to saturated soils, most are beginning to recover as conditions gradually improve.
The outlook for Manitoba crops will depend largely on weather conditions over the coming weeks.
Many areas retain excellent yield potential, particularly winter cereals, canola and corn. However, continued wet conditions could lead to additional disease pressure, delayed field operations and further crop losses in low-lying areas.
For producers managing flooded fields and hail-damaged crops, the focus now shifts toward recovery, disease prevention and protecting yield potential through the remainder of the growing season.
