Soybeans most of the crop ranges from very late R5 (beginning seed) to R6 (full seed) with some leaf colour turn starting to be noticed on some crops. Some fields of very early varieties are approaching R7 (beginning maturity).
- Additional rainfall in some areas of the province has led to a continued improvement in the crop condition in those areas and a lessening of concern by producers as crops continue seed and pod filling. However, areas of the province, such as the Interlake, remain significantly lacking in soil moisture with those soybean crops continuing to suffer from moisture stress and yield loss. At the same time, there are areas of the province (particularly in the Central Region) where recent rainfall was very excessive, leading to localized flooding, saturated soils and standing water in fields. Producers in these areas took actions to increase water drainage off their fields and continue to monitor the condition of their soybean crops.
- With the move into the R6 growth stage by soybean crops across the province, risk of economic yield loss from soybean aphids or two-spotted spider mites has significantly decreased. Enquires about these insects along with scouting and insecticide applications have subsided as well, with growers shifting their focus to harvest of other crops.
- Overall disease levels in soybeans, particularly for foliar diseases remain low. Some stem and root diseases, typically in headland areas, low areas and compacted areas of fields have been noted. There have been a number of enquires about white mold, as the presence of this disease in crops has become a lot more noticeable at this time. See this week’s Bean Report for more information on white mold and the other stem diseases of soybeans to be on the watch for.
- With the recent rainfall events in some areas of Manitoba, severe weather and hailstorms have occurred causing damage to soybean crops necessitating detailed field evaluations.
- Leaf colour turn has been noticed on early varieties over the last week. A sure sign that the end of August is almost upon us.
- Producers are starting to make plans around any desiccation or pre-harvest chemical applications they may be doing. Check out our Soybean Maturity Guide to help you navigate your crops progress as we wrap up the 2025 crop.

Field peas are at the harvest stage with harvest proceeding when possible
- With the crop ready to harvest and desiccation well completed, the recent rainfall has frustrated field pea growers. While some harvesting progress had been made, many growers expected to be done by now but have been held back by intermittent light rainfall, showers or even mists occurring after major rainfall events had passed.
- Concerns around crop canopies breaking down and stem degradation, leading to wet mushy lower canopy material that is resistant to drying off, are in the minds of growers right now. Such conditions can lead to a slow harvest, difficulty picking up the crop and increased risks of discoloured seeds and earth tag occurring in the combine.
- For the harvesting that has been done so far, field pea yields have ranged from the mid 40 to 80 bu/ac levels with lots variability between fields reflecting the dry growing conditions experienced this year. The greatest amount of harvest progress has occurred in Southwest and Central Manitoba with fields in Eastern Manitoba lagging the furthest behind.
Dry beans range from late R7 (full seed) through R8 and R8.5 (beginning to mid maturity) with some fields approaching R9 (full maturity) depending on bean type and variety.
- White mould continues to be noted in fields, particularly in areas that received greater and more consistent rainfall amounts accompanied by cooler conditions over the last few weeks.
- Producers are preparing for and/or starting to desiccate some of their crops.
Faba beans most of the crop ranges from late R6 (beginning maturity) to R7(mid maturity)
- Overall, low levels of foliar and stem disease levels faba beans continued to be noted. Some symptoms of white mould, anthracnose and Botrytis fabae or chocolate spot have been found. A wide range in plant height and expected yield potential across fields have become very apparent as the growing season comes to an end reflecting the overall dry conditions and variable rainfall that occurred across the province this year.
- Growers concerns about lygus bugs in their faba bean crops have lessened considerably, as seeds and pods become firm enough to prevent lygus bugs from penetrating them.
- Producers are preparing for and/or starting to desiccate some of their crops.
