Flea beetle damage in some early-seeded canola

MAFRI crop report

Weekly Provincial Summary

Seeding progress in Manitoba is estimated to be 94 per cent complete. There remain some areas in the Southwest and Central Regions where seeding is not as advanced. However, progress was made over the past week and favourable weather conditions will allow producers to continue seeding.

Stand establishment is generally rated as good to excellent for most crop types. However, the excess moisture in some areas did impact crop emergence and plant stands, mainly in the low areas of the fields.

Weed control is a priority for producers as crops continue to advance.

Increased flea beetle activity in the earliest-seeded canola fields has been reported.

Southwest Region

Rainfall amounts across the Southwest Region were variable, but generally ranging from five to 20 mm; heavier amounts were received in isolated thundershowers. The recent rains are beneficial to emerging oilseeds that were damaged by last week’s series of frost events. Soil moisture is generally adequate across the region but surplus along the Manitoba-U.S. border.

Weed control spraying operations are underway with progress on seeded acres ranging from 10 to 25 per cent complete across the region. Weed control measures are complete on the remaining winter cereal acres.

Insect issues to date are limited to flea beetle post-emerge control in canola, especially in early-seeded fields that were hit by last week’s series of frosts.

Pasture and hay growth improved over this past week. However, growth continues to be delayed due to the cooler temperatures and last week’s frost.

Northwest Region

The Northwest Region received rainfall over the week, with Ste. Rose receiving 38 mm, Roblin 20 mm, The Pas 11 mm and similar amounts were recorded in Dauphin.

Seeding is complete in most areas with 10 per cent remaining in The Pas. Herbicide spraying is well underway in Swan River and 10 to 15 per cent of the acres were sprayed in the Roblin area.

In areas north of Roblin where frost occurred, flea beetle activity is being monitored.

Recent rainfall on the western side of the region and warmer temperatures throughout the region aided forage and pasture growth. Alfalfa is at the early- to late-bud stage indicating dairy haying operations will be within the next two weeks. Hay growth is quite variable from field to field and early estimates for expected first-cut yield are 1.8 to 2.0 tons per acre.

Central Region

Rainshowers were sporadic throughout most the Central Region during this past week. Amounts reported range from trace amounts to 12 mm in isolated pockets. Rainfall amounts however, in the Rosendale area were upwards of 125 mm this past weekend. The eastern and south side of the RM of Pembina is still recovering from excessive rain this spring.

Seeding in the Central Region is mostly complete at 95 to 100 per cent in most areas. There are reports of broadcast seeding canola, followed by harrowing, on fields that producers were unable to previously seed.

Edible beans will continue to be seeded until AgriInsurance deadlines arrive.

Winter wheat development is variable this year. In the Red River Valley, 10 to 15 per cent loss due to winterkill is being reported. Areas in the western part of the region are reporting 40 to 50 per cent winterkill.

Tan spot in spring wheat is reported on fields that had wheat residue from previous years. Reports of flea beetle feeding on young canola seedlings have prompted some producers to spray. Fields that were seeded more than two weeks ago are the ones where flea beetle damage seems to be most severe.

Alfalfa is growing but no flowering observed to date. Pastures are growing well. Dugouts are full.

Eastern Region

Rainfall amounts of five to 65 mm fell this past week in the Eastern Region.

Seeding in the Eastern Region is estimated at 99 per cent complete. Crops are rated good to excellent in the region; timely rains and recent warm temperatures helped with even germination and early seedling development.

Herbicide applications are now underway.

In the northern area of the region, some sunflower fields were sprayed for cutworms. There is also some cutworm damage reported in canola. A few fields of winter wheat were impacted by wireworms and were reseeded. Flea beetles are evident in earlier-seeded canola. Those stands are now four weeks from date of seeding; fields will continue to be monitored.

Hay and pasture conditions in the region are rated as 75 per cent to 85 per cent good to 15 to 25 per cent fair. Most livestock in the region are out on pasture. Livestock water supply, including dugouts, is rated at 100 per cent adequate.

Interlake Region

Precipitation amounts averaged two to 10 mm. Seeding throughout the Interlake Region is 95 per cent complete. South Interlake acres are completely seeded, while in the Arborg area, a small percentage of acres remain and in the Ashern area, 20 per cent of acres have yet to be seeded. Spraying is in full swing in South Interlake; applying herbicides to most cereals and an early burn-off in soybean and canola fields. Spraying is nearly complete in winter wheat fields in North Interlake; some acres of soybeans and canola were sprayed as well.

A number of Arborg producers had to reseed canola fields as a result of last week’s frost.

First-cut haying began last week for some producers. Most hay stands still require rain and warmer temperatures to help plant growth. Pastures are slowly starting to perk up and, with last week’s rainfall and future forecasts of warm temperatures and precipitation, the pastures may begin to green up. Dugout conditions are good.
