I guess nightshade doesn't get frost bite

The sight of nightshade's purplish/black berries in a "food grade" soybean crop is every producer's worst nightmare. They stain the seed and dramatically reduce the value of the crop. In theory, you would kill uncontrolled nightshade prior to harvest with either a herbicide (i.e. Reglone, glyphosate) or mother nature (i.e. a frost), the berries would drop to the ground, never go through the combine and the seed would be left unstained. Unfortunately this is a theory, and reality shows us… Continue

Field Bindweed Control in the Fall

Field bindweed is an aggressive perennial weed that reduces crop yield and slows harvesting speed especially in soybeans and cereals. Eradication is impossible, but minimizing its impact in field crops is possible with a management strategy that includes a fall application of glyphosate at 1.5 L/ac (360 g/L concentration). The photo below was taken in late May of 2004 and compares field bindweed populations in the untreated… Continue

Watch for the development of Sclerotinia stem rot in canola

Information is OFFERED TO THE PUBLIC FOR INFORMATIONAL PURPOSES ONLY. Agriculture and Agri-Food Canada, Environment Canada, and their employees assume no liability from the use of this information.   June surface soil moisture conditions indicate that much of the Prairie canola growing region currently has sufficient soil moisture to support germination of Sclerotinia sclerotiorum sclerotia (Fig. 1). Cumulative rainfall from May 30 – June 28 was the highest in the Edmonton, Lethbridge, Winnipeg areas, and lowest in northern Saskatchewan and the Peace River area of Alberta (Fig. 2). When rainfall over the whole growing season (April 1 – June 28) was considered, the Edmonton area was much higher than average (Fig. 3). Recent heavy rains across the Prairies have significantly increased these amounts. Temperature over the May 30 – June 28 period was highest in southern Manitoba and eastern Saskatchewan and lowest in western Alberta (Fig. 4). For the whole growing season temperatures have

Table Beet Harvest has Begun

Ontario's 2026 fresh beet harvest is underway with a positive outlook and steady supply, reinforcing the province's position as Canada's leading producer of this resilient crop.

Cereal rust risk report April 1 to June 29 2026 stripe rust reported in Alberta and eastern Canada along with leaf and stem rust in eastern Canada

Stripe rust development in Alberta There are reports of stripe rust developing in Alberta, though at low levels to date. The wheat crop is maturing in the Pacific Northwest and will decline as a source of inoculum as it is harvested. The spread and development of stripe rust in Alberta now depends more on weather and crop conditions within the province going forward. No rust reports to date in Saskatchewan and Manitoba Cereal crops in the southern US states have nearly been harvested and were affected severely by drought this crop season. Spring cereals in the northern states are still developing but there are no reports to date of rust infection in these northern states. Crop development in many parts of Saskatchewan and Manitoba is delayed relative to normal, and frequent and heavy rains raise the risk of disease development in all crops. To date though there have been no reports of rust development in Saskatchewan and Manitoba. Cereal rusts reported in eastern Canada Colleagues
