Drier weather heats up growing conditions

Weekly Provincial Summary

  •  A return to warm and drier conditions is welcomed by many Manitoba producers.
  •  All crop types, particularly the warm-season crops of grain corn, sunflowers, edible beans and soybeans are benefiting from the recent change in weather.
  •  The favourable weather conditions are also allowing acres impacted by excess moisture to recover. However, there are portions of fields that are still showing symptoms of excess moisture stress, including yellowing and slowed crop development.
  •  The improved weather conditions are also allowing herbicide and fungicide applications to continue. Aerial application is needed in cases where fields remain too wet for ground application.
  •  Haying operations are underway in most regions with average to below-average yields and good quality being reported.

Southwest Region

The Southwest Region saw minimal rainfall over the past week. However, there were some isolated events that caused larger rainfall accumulations, high winds and hail.

Crops and weeds are advancing rapidly with the heat and most herbicide spraying needing to be completed this week.

Early-seeded cereals are in the heading stage. Fungicide application is occurring in most areas. Early-seeded canola crops are starting to bolt with the majority cabbaging out and covering the ground.

Flooding continues in the Assiniboine and Birdtail valleys.

Producers have started to cut hay with average to below-average yields reported. Pastures are rated as good and the warm weather will aid in continued growth.

Northwest Region

Late-seeded and less-developed canola and hemp were the most impacted by excess moisture, especially in those soils with poor drainage or those areas that received higher rainfall accumulation.

Cereals are predominantly into late stem elongation stage with 15 to 25 per cent of spring wheat acres heading. Approximately 10 to 15 per cent of canola acres are flowering and over 45 per cent are into rosette stages. Field peas are beginning to bloom. The soybeans crops through Dauphin and Ste. Rose areas are developingwell and past the fourth trifoliate stages.

Herbicide applications in later-seeded canola acres are in progress. Fungicide treatments in winter wheat are complete. Aerial applications also continued. Fungicide applications are beginning on cereals and canola crops.

Hay crops and pastures remain in good condition across most of the region, except where higher rain accumulations have occurred. In the south, initial first hay cuts continued sporadically due to rains. Heat is required before haying operations become general. Yield is expected to be average to below average. Dugout water supplies are now full.

Central Region

Rainfall accumulations in the Central Region ranged from five to 30 mm. A few pockets of isolated hail were reported with some causing crop damage. All areas of the region report some concerns of excess moisture. Some crops have continued to show signs of related stress symptoms.

Clearing skies allowed producers to resume spraying; herbicide applications are now over 95 per cent complete. Fungicide applications continue.

Corn continues to recover from the extended cool and rainy conditions and the earlier frost event. Crop height is considered shorter than normal.

Soybeans and edible beans are showing signs of yellowing and iron chlorosis due to excess moisture and cool conditions.

Dairy and export hay harvest has started with much of it put up as haylage/silage. The quality on first-cut alfalfa/grass hay crop is good to fair. Hay crop appears to be average this year with moderate to slow growth; cutting has also been delayed due to poor weather conditions. Most pastures are in good shape. Alfalfa weevil is causing damage in alfalfa.

RM of Pembina reports dugouts are 30 to 40 per cent full. Some producers are exploring alternative water sources.

Eastern Region

Winter wheat and fall rye crops are either at the milk or early-dough stage. Fungicide applications on fall cereals as well as herbicide applications on all crops are close to complete. Across the region about 70 per cent of the canola has begun flowering and fungicide applications for sclerotinia are proceeding. Flax is in the stem extension growth stage. Sunflowers are in the vegetative stage. Soybeans are in two- to five-trifoliate leaf stages. Corn is in the V6 to V9 growth stages. In general, the condition of annual crops is rated as good.

First-cut haying is proceeding across the region with at least 30 per cent of the crop cut or baled. Overall quality is rated as good.

Pasture conditions are generally rated as fair to good.

Interlake Region

Heavy rain fell on many parts of the Interlake Region in isolated thundershowers. Water is standing in low spots and has resulted in visual crop damage. Fungicide and herbicide application is delayed on some fields and is expected to resume in coming days with sun in the forecast.

Cutworm damage on canola and soybean was reported in the Arborg and Fisher Branch areas. Producers should be scouting for zebra caterpillar populations as there has been a report of activity in the Fisher Branch area on alfalfa seed.

Forage seed grasses are progressing rapidly producing large volumes of vegetation.

Haying resumed late in the week.

Pasture conditions have improved greatly although some areas that have received too much rain have water ponding.
