Research Shows Impact Of Root And Crown Rot In Wheat

Kazakhstan is the ninth largest country in the world and the fourteenth largest producer of wheat; in 2021 alone, the country produced 14.3 million tons (t) of wheat on 12.1 million hectares (ha). Despite this impressive figure, wheat yield in the country falls below average at 1172.5 t/ha compared to 3474.4 t/ha globally.

Research into wheat diseases in Kazakhstan has primarily revolved around airborne fungal foliar diseases, such as stem rust, leaf rust and stripe rust, which can be devastating for farmers and their crops. However, the effects of fungi relating to wheat root and crown root were yet to be examined – these diseases affect yields, stands and grain quality due to infections that cause damping-off, blight, necrosis, and dry rotting.

Using plant samples taken during the 2019 growing season, scientists from the International Maize and Wheat Improvement Center (CIMMYT) conducted a quantitative survey to determine the distribution of this fungi. Using morphological and molecular tools on 1,221 samples from 65 sites across the central, eastern, and southeastern region, scientists found that Bipolaris sorokiniana and Fusarium acuminatum were the most predominant fungal species isolated.

In total, 74 isolates from 16 species were tested, revealing that F. culmorum and F. pseudograminearum, B. sorokinaiana, Fusarium sp., R. solani, F. redolens, C. spicifera, C. inaequalis, and N. orvzae were virulent fungi.

Exploring the AgriSuite Greenhouse Gas Decision Support Tool

Video: Exploring the AgriSuite Greenhouse Gas Decision Support Tool

The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) has developed a free online feature for farmers to help them measure their greenhouse gas (GHG) emissions on-farm and explore options for reducing their carbon footprint.

In this webinar, you'll hear from James Dyck, an OMAFRA engineer who helped design and build the tool now available on AgriSuite. Anyone interested can use the tool to input custom details about their farm operation at https://agrisuite.omafra.gov.on.ca/ and by selecting the Greenhouse Gas option.

You'll also benefit from a step-by-step walk-through of the tool from Norm Lamothe, a farmer outside Peterborough who has used the tool to make decisions on his own farm and assess the impact of different mitigation practices.
