Fall application of Zero Grind limestone performed similar to spring applied hydrated lime. Generally, both products applied at 10 t/ha increased soil pH, reduced disease severity, increased yield and reduced spore density of P. brassicae in the soil. Clubroot, caused by Plasmodiophora brassicae Wor., is well...
A three year survey found that foliar disease incidence on faba bean was more than 75% in Alberta and Saskatchewan reaching 100% in Alberta in 2019. The major fungal genera identified were Alternaria, Botrytis, Fusarium and Stemphylium. Botrytis fabae, which primarily causes chocolate spot disease,...
Applying a foliar fungicide at BBCH65 (50% anthesis) effectively suppressed Fusarium head blight. Fusarium head blight suppression when application was delayed up to the end of anthesis at BBCH69 was statistically similar to application at BBCH65. Spray timing at BBCH59 when the wheat head was...
The highest ergot incidence and severity occurred in rye, followed by bread and durum wheat, barley and oats. Ergot incidence has increased in the last decade, but severity has not increased and remains low. Ergot is a fungal disease that is caused by the pathogen, Claviceps...
For susceptible and moderately resistant varieties sown in mid-May, a foliar fungicide application at mid-anthesis will help preserve yield and quality. When susceptible and moderately resistant varieties are sown in early June in central Saskatchewan, fungicide application at stem elongation or mid-anthesis was equally beneficial...
One fungicide application at mid-flowering was as effective as a dual fungicide application at early- and mid-flowering stages for disease control, quality parameters and yield increases. A dual mode-of-action foliar fungicide is recommended for fungicide insensitivity management. Pasmo is a fungal disease, caused by the pathogen...
In years of moderate disease pressure with cultivars rated as intermediate resistance to ascochyta, two foliar fungicide applications were as effective as four applications for disease management, yield protection, and prevention of seed infection. Chickpea can be a profitable crop in southern Saskatchewan, and is an...
In susceptible varieties, a single foliar fungicide application at flag leaf reduced stripe rust severity and protected yield potential. A single fall foliar application was not effective. A moderately resistant variety did not require a spring foliar application. Stripe rust of winter wheat, caused by Puccinia...
Rainfall was the most contributing factor to Fusarium Damaged Kernels. Glyphosate application did not affect grain quality or Fusarium Damaged Kernels. Fusarium head blight is one of the most damaging diseases on hard red spring wheat on the Prairies. A research study led by the University...
FHB status updateFusarium head blight incidence increased steadily after 1995, peaking in the epidemic year of 2016, but with low levels since then. Severity has remained relatively low over time, and not always correlated to incidence levels. Fusarium head blight (FHB) emerged as a serious disease...
