Digging into Research
Botrytis grey mould doesn’t share the same limelight as Anthracnose or Ascochyta blight, but it can be an occasional foliar disease in lentil. Limited research has been conducted on foliar fungicide application timing, but one study in 2002 and 2003 found that a single application...
Fungicide applications at flag leaf emergence and heading growth stages reduced net-blotch severity and increased malt barley grain yield and kernel quality, but early fungicide applications at the 2- to 3-leaf stage generally had a limited impact. Placement of seed with 11 inch shovel openers...
Research trials found that hydrated lime may be an effective tool for managing clubroot disease in canola when optimal timing and rainfall are achieved. Field and greenhouse trials found hydrated lime more effective than limestone applications, but is much more costly. Clubroot disease, caused by Plasmodiophora...
For improved leaf disease management and yield in malt barley, fungicide applications should include a flag leaf stage timing or later for adequate protection of upper canopy leaves, which are key contributors to yield and grain filling. A tank-mix of a one-half rate fungicide with...
Surveys of alfalfa seed production fields on the Canadian Prairies from 1993 to 2017 demonstrated that epidemics of blossom blight caused by Botrytis cinerea Pers. and Sclerotinia sclerotiorum (Lib.) de Bary developed almost every year at some locations. It appears likely that blossom blight continues...
Researchers investigated the efficacy and durability of canola lines carrying single and multiple clubroot resistance (CR) genes against 'new' and 'old' pathogen pathotypes. Stacked CR genes of different modes of action improved resistance and enhanced durability. Cultivar resistance is a cornerstone of clubroot management. Most canola...
In 10 of the 13 trials, double-nozzle configurations provided a 15% reduction in disease severity and up to a 60% increase in yield compared to the untreated control. However, droplet size and angle of application had no effect on field pea yield. Moderate water volume...
The most profitable practices were applications of propiconazole (Tilt 250E0), benzovindiflupyr and azoxystrobin (Trivapro A+B) at BBCH 39-45 (flag leaf) or prothioconazole and tebuconazole (Prosaro XTR) at BBCH 61-63 (early anthesis) -- when environmental conditions were conducive for disease development. The objective of this study was...
Application of foliar fungicides at the 2 to 4 leaf stage reduced blackleg disease incidence and severity, and improved yield on the susceptible Westar canola cultivar. On two resistant cultivars, however, this fungicide treatment reduced the disease but showed no yield benefit. Since resistant canola...
All of the fungicides and fungicide mixtures tested in field experiments reduced root rot in Fusarium infected soybean seedlings. Varieties were identified that could be used in plant breeding programs to develop Fusarium-resistant varieties. The potential for growing soybean in southern Alberta has increased with the...
