As the middle of the growing season approaches, it comes time to check crops for disease and pests, and to check your legume crops for nodulation. This week on Growing Possibilities we will be discussing nodulation, with a focus on soybeans. What is nodulation? How do I check for it? What can I do if it does not occur? Nodules on the roots of all legume crops are the result of a symbiotic relationship between leguminous plant roots and nitrogen-fixing bacteria. Symbiotic bacteria fix nitrogen from the air in...

Last week on Growing Possibilities we discussed the yield-limiting canola disease Sclerotinia Stem Rot. This week, we are continuing with this theme of canola disease and discussing what is likely the most destructive disease North American canola growers have to worry about: Clubroot. Clubroot is caused by the soil-borne pathogen Plasmodiophora brassicae, which colonizes canola roots and prevents uptake of water and nutrients by their host plants. This infection begins in the root hairs before eventually invading root tissues and causing large growths or galls to form on roots...

As the cropping season moves along we are starting to see flowering in many crops, and with flowering comes the presence of pests and diseases. Whether it’s on Twitter or in Research publications, the problem of Sclerotinia Stem Rot is on Canola growers’ minds right now. This is one of the most destructive diseases in canola, and has become a yearly concern for canola growers all over Canada, with 2020 being no different. In this week’s edition of Growing Possibilities, we are going to discuss Sclerotinia Stem Rot...

Fusarium Head blight (FHB) is a fungal infection caused by species in the Fusarium genus of fungi and has been one of the most economically costly diseases in cereal production in North America since the 1990s. Between 1993 and 2001, FHB caused an estimated loss of $2 billion USD in the USA and an estimated loss of $520 million CAD in Canada (1). Hot, humid conditions just prior to flowering (as we are seeing this year in Manitoba) are the ideal conditions for Fusarium to develop, so what...
