Researchers explored FHB management strategies focusing on a systems approach of Genotype (G) x Environment (E) x Management (M) interactions. They reviewed current literature, and included a recent western Canadian FHB research project as a case study of this approach. The results showed that a...

Using a cultivar with greater disease resistance and applying a fungicide reduced leaf spot diseases in winter wheat. Fungicide application resulted in a 3.3 to 13.2% (2 to 8 bu/ac) yield increase over the untreated check. Leaf spot diseases are commonly seen on winter wheat in...

Research found that foliar fungicide application at early anthesis for Fusarium Head Blight control also provided adequate control of leaf spotting diseases. While leaf spotting diseases were slightly higher at this timing, yields were similar. In years when environmental conditions are favourable, leaf spot disease can...

Mechanical wounds on canola cotyledons, simulating flea beetle feeding, allowed infection of the blackleg pathogen while no infection occurred on un-injured cotyledons. Wounds that were 8 hours or older before inoculation had lower levels of infection. Temperature, leaf wetness and relative humidity also played a...

The application of hydrated lime to bring an acidic soil up to pH 7.2, and/or weed control of cruciferous weeds did not affect clubroot severity on a clubroot resistant variety. The yield of a susceptible canola variety almost doubled with the application of hydrated lime,...

Yield losses to clubroot disease, caused by Plasmodiophora brassicae, increased linearly as the Disease Severity Index (DSI) increased. Under greenhouse conditions, an increment of 1% in DSI resulted in a decrease of 0.9% to 1.0% in yield; under field conditions, this percentage was reduced to...

Ten lentil cultivars were found to be susceptible to Sclerotinia white mold and Botrytis grey mold. The highest yields were found on dryland plots at a seeding rate of 16 seeds/ft2. Irrigated plots yielded significantly less, and had significantly higher disease incidence. Sclerotinia white mold, caused...

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...
