Factsheet: Bacterial Leaf Streak and Black Chaff of Cereal Crops in the Prairies
- Wheat
In recent years bacterial leaf streak and black chaff, caused by Xanthomonas transluscens pv. undulosa, have become more prevalent in the Prairie provinces due to favorable conditions. Bacterial leaf streak is an important disease of cereal crops all over the world, and can cause a significant reduction in yield. It has been reported that severe infections can reduce yield by up to 50%,1 however losses this significant have not been reported in Western Canada.
THE CANADIAN MALTING BARLEY TECHNICAL CENTRE (CMBTC) RECOMMENDED LIST provides producers with an indication of which malting barley varieties have the greatest potential for selection and marketing. Each variety on the recommended list has been tested at the CMBTC and… Read More
Rapid visco analysis (RVA) is the assessment used to determine the degree of pre-germination in barley grain. This measurement is used to assess nonvisual pre-germination. Read More
This document is designed as a guide for use in proactively scouting wheat fields to detect pests at or before they cause damage. Read More
Manitoba growers know the devastating impacts of hail on wheat due to unstable spring and summer weather. Assessing hail damage can be very difficult, but there are steps you can take after hail events to evaluate crop damage. Read More
Armyworms (Mythimna unipuncta), sometimes called true armyworm, are a pest species that impact winter wheat, spring wheat, fall rye, barley, forage and pasture crops. Armyworm moths do not overwinter in Manitoba – they migrate from the southern U.S. to the… Read More
Manitoba farmers are well aware of the destructive abilities of wireworms. They feed below ground on many different crop types, causing early season plant stress. Feeding also results in thinning plant populations and reduced yield. Read More
Fusarium head blight (FHB) is a serious fungal disease that mainly affects wheat (including durum), barley, oats, and corn. FHB causes economic losses in three ways: 1) yield losses; 2) downgrading of grains; and 3) mycotoxin contaminations reducing grain marketing… Read More
Cereal rusts are a threat to Prairie wheat and barley production annually. Cereal rusts include leaf rust (Puccinia triticina), stem rust (Puccinia graminis) and stripe rust (Puccinia striiformis). All three rust pathogens can cause widespread devastation and crop loss, especially… Read More
Early season weed control can be key to optimizing yield and giving your crop a good head start. Even small weeds compete with your crop for moisture and nutrients while also acting as a host for insects and diseases. Controlling… Read More
