Aim to synchronize nitrogen supply with crop demand

Primary targets for emissions reductions in Western Canada should be the controls on emissions occurring at spring thaw and enhanced synchronization of nitrogen supply with crop nitrogen demand. “Balancing agronomic and environmental outcomes using enhanced efficiency nitrogen fertilizers,” Richard Farrell and Kate Congreves, University of Saskatchewan.

Nitrogen-fixing bacteria need more work

Evaluation of a commercial nitrogen-fixing bacteria product showed that the bacteria did colonize many of the root and shoot tissues, but most did not show strong evidence of nitrogen fixation. In many cases, the percentage of nitrogen in the plants that were colonized was lower than the control (not inoculated) plants. “Advanced N management for...

Spore threshold for sclerotinia stem rot risk

Frequent occurrence during the flowering period of a minimum of 0.0001 nanograms of S. sclerotiorum DNA per petal or per cubic metre per hour combined with relative humidity over 80 per cent and cooler temperatures are expected to result in a disease incidence greater than 10 to 15 per cent. In this situation, fungicide is...

Sclerotinia spore sensor gets a patent

InnoTech researchers have patented an automatic field unit that can count Sclerotinia sclerotiorum spores over a set period of time. They deployed six units in 2022 and are troubleshooting mechanical issues, mostly to do with the system’s internal clock and power supply. “Development of a biosensor for sclerotinia stem rot disease forecasting in canola,” Xiujie...

Seed treatments protect susceptible cultivars from blackleg

Fluopyram, Saltro and Bion seed treatments look promising against early blackleg infection, however none of these seed treatments has shown significant additional efficacy on any of the resistant canola cultivars tested under field conditions. “Exploring novel seed-treatment options to mitigate the impact of blackleg on canola,” Gary Peng, AAFC Saskatoon SaskCanola Peng G, Liu X,...
