An early pasmo symptom is brown lesions on flax leaves.

Pasmo in flax every year, but severity varies

That makes decisions about applying a fungicide to protect the crop challenging sometimes

If you grow flax in Manitoba, it will have pasmo. The fungal disease, also known as Septoria linicola, can be found in every western Canadian flax field, every year. But the severity varies, making it tricky for farmers to decide whether to apply a fungicide, says Rachel Evans, the Flax Council of Canada’s extension agronomist.

Warm temps make for good growth, crop insect and disease stress seen low

Manitoba Crop Report and Crop Weather report for July 4, 2017

Precipitation amounts are below average for much of the province. Crops in the Southwest Region and the western part of the Central region would benefit from moisture. Crops in most regions are in good to excellent condition. Warmer temperatures are improving growth of warm season crops. Insect and disease pressure remains low in field crops.


Early flowering is the best time to spray wheat with a fungicide to protect it from fusarium head blight but first assess how much risk of the crop being infected.

Heads up on fusarium head blight

Early flowering is the time to apply a prophylactic fungicide on wheat but first assess the field’s disease risk

It’s time to turn a weather eye on cereal crops for fusarium infections. Fusarium head blight damaged a lot of Manitoba spring wheat last year and farmers should be assessing this year’s risk from the fungal disease that can cut wheat quality and yield. Since wheat is most susceptible to fusarium infection at flowering, early

Alfalfa weevil levels rapidly decline, high levels of pea aphids still seen

Manitoba Insect & Disease summary for July 13

Summary Insects: Levels of alfalfa weevil larvae are rapidly declining in some alfalfa fields as the larvae mature to pupae. Pea aphid levels are still a concern in some pea fields. Aphid levels are being monitored carefully in some cereal fields; high levels of natural enemies have also been noted in some of these fields and may be

The take-home message for soybean growers and agronomists in Manitoba is not to overdo soybean management, says an Ontario soybean specialist.

Soybeans — the ‘kitchen sink’ strategy works, but…

Ontario trials suggest early seeding is the best and cheapest management practice

Intensive management can improve soybean yields, but growers should evaluate whether each strategy pencils out, says a soybean specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs. Speaking at the Manitoba Agronomists Conference (MAC) in Winnipeg in December, Horst Bohner described more than a decade of research to evaluate various management strategies to

Data suggests there is most white mould suppression and increased yield when fungicides are applied at the R1 growth stage.

Soybean white mould control options limited

In contrast to canola, there are only four products registered

While many Manitoba growers are familiar with the extensive number of fungicides available for dealing with white mould (sclerotinia) in canola, they may not realize that there are a lot fewer options to treat this disease in soybeans. Only four foliar fungicides are registered for control or suppression of white mould on soybeans: Acapela (DuPont),

Conditions as of July 20, 2015

Another week of generally good growing conditions continues to advance crops across Manitoba. Localized thunderstorms did result in significant precipitation amounts in some areas of the province, while other areas would still benefit from additional moisture. Disease pressure and insect activity continues to be monitored as the growing season progresses. Click here for the Crop Weather Report for

VIDEO: Count your flowers before deciding to spray canola for sclerotinia

Crop Diagnostic School: Whether your pants get wet when walking through the field can tell you if it's a good time to spray a fungicide

Assessing your canola crop during the flowering stage is essential to discover if sclerotinia is present and if a fungicide can be of benefit. In this video from the 2015 Crop Diagnostic School, Anastasia Kubinec of Manitoba Agriculture, Food and Rural Development (MAFRD), talks about the risk factors for the fungal disease and offers tips for canola

Conditions as of July 13, 2015

Hot and humid weather conditions resulted in rapid crop growth across most of Manitoba. Generally, condition of most crop types is rated as good, although variability is noted across the province. Majority of acres and crop types have entered the flowering and grain fill stages of development. Although many areas did receive much needed rainfall,
