Pulse and Soybean Crop Update for Eastern Manitoba for Sept. 2, 2026

Field Peas:

Field pea harvest is ongoing with the crop harvest ready and dried down. Intermittent rainfall events are behind any delays experienced by growers.
Harvest progress is the most complete in the central region of Manitoba with the end of field pea harvest now in sight and the final acres expected to be done this week if weather cooperates. Harvest progress in the eastern and Interlake regions is at close to 60 per cent complete with rapid progress expected as long as weather conditions hold.
Quality is described as good while yields are usually quoted as average with a few fields that experienced more optimized soil moisture conditions showing above average yields.
According to Manitoba Agriculture – provincial average yields for field peas were as follows: 2023 – 49.9 bushels per acre, 2024 – 51.1 bushels per acre, 2025 – bushels per acre. Informally amongst growers and agronomists, we’ve found that average field pea yield for eastern Manitoba is often considered to be 60 bushels per acre with above average being considered 70 plus bushels per acre.

Soybeans:

In the vast majority of fields, have achieved the R6 growth stage (pods contain green seed that fill the pods to capacity at one of the four uppermost nodes of the mainstem). Leaf colour change (i.e. yellowing) has been noted on headlands and compacted areas of many fields. A few fields of very early maturing varieties being grown primarily for seed are at early R7 (at least one pod on the main stem has reach mature colour (brown/tan).
Now that R6 is upon us, producer and agronomist concerns around insects, primarily soybean aphid and two-spotted spider mite, have justifiably tailed off. Economic thresholds for both these insects skyrocket once soybeans reach R6 and the crop will rapidly become unattractive to these pest species as they progress to R7.
Wilting soybeans, either because of of root rots or white mould infections, are becoming more apparent in fields as crop maturity progresses. The second round of the provincial soybean disease survey has commenced at this time to specifically look for soybean plants with diseases of the root and stem. Look for updates on survey results on our website in the coming months. Growers and agronomists are encouraged to explore their fields at this time to get a handle on root and stem disease presence and incidence level as wilting symptoms will be most obvious now before leaf drop proceeds any further.
