Soybean development moving ‘very quickly,’ insect pressures rise on thin pesticide supply

Soybean development moving ‘very quickly,’ insect pressures rise on thin pesticide supply

Manitoba Crop Report: Issue 14, August 9, 2022

Overview Soybean aphids are reaching economic thresholds in scattered locations across Manitoba. Spraying is occurring as-needed, but crops require intensive scouting on a field-by-field basis. Grasshopper pest species are present in all regions – mostly confined to field edges and headlands but moving more as insects reach adult (winged) stages and travel further into fields.

Oat leaves display chlorosis discoloration, one of the first signs of barley yellow dwarf virus.

Barley yellow dwarf virus confirmed

Despite the name, the pathogen can infect any small-grain cereal crop

An aphid carrying the barley yellow dwarf virus has been making itself known in Manitoba this year. The bird cherry-oat aphid is the main suspect when it comes to spreading the insect-carried disease, which does not spread through dirt or seed. Why it matters: While barley yellow dwarf virus, or “red leaf” when it’s found

Manitoba crops variable: report

MarketsFarm – Crop development was highly variable across Manitoba during the week ended Aug. 2 depending on localized rainfall and drainage, with fields in the southern growing areas of the province generally better than those to the north, according to the latest report from Manitoba Agriculture. Localized insect concerns were reported, with some spraying required.

Crop development varies widely, watch closely for pest insects

Overview Fungicide application is slowing across Manitoba, as crops grow past the appropriate timing windows. Producers have done much more fungicide application in 2022 than in recent years. A few insect concerns have popped up in localized spots across Manitoba, with bertha armyworm spraying reported in the Eastern region. Soybean and pea aphids have been

Fungal diseases posing an issue with Manitoba crops

As crop conditions vary across Manitoba, the latest crop report noted that frequent rains and warm temperatures have increased the risk of a number of fungal diseases. Manitoba Agriculture and Resource Development (MARD) said farmers continued to apply fungicides on their wheat, oats, barley, canola, and pea crops. However, wet conditions in a number of

Overview Rainfall amounts varied across the province with the highest amounts falling in the Eastern and Interlake regions. Most locations in Manitoba received between 20 to 60 mm in the preceding seven days. The Northwest region is the exception, where rainfall amounts ranged from 1 to 32 mm. Frequent rains and generally warm temperatures have

Research projects look at how to manage, not eliminate, this pasture weed

In terms of nightmare plants for pasture management, leafy spurge is a scary one. It’s an official noxious weed, invasive, deeply rooted, able to spread through both seed and creeping roots and almost impossible to eliminate. Its thick patches can wreak havoc on pasture productivity for most outdoor livestock species, goats and sheep being the

Crop diversification centres set field day schedule

See the latest trials and research at the province’s four applied research centres this summer

Manitoba’s crop diversification centres are well on their way to harvesting another crop of data from trials at their respective sites. Seeding is all or nearly complete at all diversification centres. Staff faced the same wet-weather challenges as many farmers throughout the province. The centres, located in four different climatic zones, all experienced wet and

Larger U.S. barley crop expected in 2022

MarketsFarm — Barley production in the U.S. is forecast to be up substantially in 2022, with early indications pointing to the largest crop in seven years. In its latest production estimates, the U.S. Department of Agriculture forecast the country’s 2022 barley crop at 3.8 million tonnes, which would be up from the 2.6 million tonnes
