The impacts of clubroot on susceptible canola cultivars are usually pretty obvious – the plants look drought-stricken and have large, irregular swellings (galls) on their roots. But the pathogen itself has remained somewhat enigmatic. Now a team of researchers mostly from Western Canada, led by Hossein Borhan and in collaboration with scientists from England and Poland, has sequenced the clubroot genome. This work is generating insights into the pathogen and how it functions, and is providing a springboard for future advances in clubroot management.

Across much of Ontario, major grain crops and forages are progressing well.

Crop reports by the OMAFRA field team are available online and posted as soon as possible.

Evidence of moisture stress was spotted on various crops, especially on light textured soils. However, rain came to relieve many crops over the weekend and again on June 27. Amounts of rainfall varied from zero to six inches, but even small amounts of rainfall can do an amazing job of feeding the crops. The burst of rainfall will help the crops as they battle the forecasted heat wave over the Canada day long weekend. 

It seems every year farmers are anxious over rainfall throughout the spring but especially at this important timing in many of our crops growth cycle. As farmers plant more acres further from home base, it’s important to know what the rainfall is doing across the area. If not already connected, be aware of the Community Collaborative Rain, Hail and Snow Network (CoCoRaHS), Agricorp and various crop advisor weather network stations. They can be accessed through the various service deliverers and at these websites:
Corn in general is doing very well across most of the province. On lighter soils and to north and west where rainfall has continued to be low, some moisture stress symptoms have started to appear (“onion leafing”) as crop rows fill and water demands of the crop start to increase. There should be very rapid growth of corn height over the next week with the heat and moisture. This also marks the period of rapid nitrogen uptake by the corn crop. With the exception of some local areas which have received multiple heavy rainfall events, drier conditions suggest N losses this spring are likely low. While there are about 3 planting date windows for corn across the province based on the earlier spring weather and soil conditions, all are doing well. Early planted corn in some fields is chest high already and most of the crop will surpass knee high by the 1st of July.

Disease and insect pressure has been low. There have been reports of thrips in some of the drier areas giving concern to producers. Rain has helped most fields grow out of the infestations. No thresholds exist but control would only be warranted in fields where dry conditions remain, plants show signs of stress and thrips continue to infest even new leaves on the plants.

Soybeans have now started to flower except for late planted fields. Despite some areas getting more rainfall than needed creating concern over white mold, the high forecasted temperatures will prevent it from developing, as long as temperatures remain above 28˚C. Fungal sporulation is greatly reduced under hot temperatures regardless of the amount of moisture present. For fields with a history of severe white mould a two pass foliar fungicide strategy should be considered. The first application needs be made relatively early during the reproductive growth stages (before full flower) following by a second application 14 days later.

Soybean cyst nematode symptoms are showing in many parts of southwestern Ontario and will as well in central and Eastern Ontario over the next few weeks. Above ground plant symptoms include yellow patches, stunted plants (Figure 1) which could resemble herbicide, pH, fertility deficiencies, etc. Dig up plants (don’t pull) and examine roots for cysts (Figure 2).

Aphids have not been reported in any significant numbers although some have been found in the Milverton area, so scouting will now be necessary to monitor numbers. Fields should be monitored once the crop is in the R stages of soybeans and only require protection if soybean aphid thresholds are reached. See Field Crop News for more information (Soybean Aphid Thresholds).

Winter Wheat
Lots of variation in colour across the province since crop in the south west is maturing rapidly with harvest anticipated to start then as soon as the first week of July. The rain that was received was very important to grain fill and providing for maturity to occur as expected. Prior to the onset of recent rains, some crops on lighter soils did have potential yield impacting moisture stress which may be seen at in the combine.

The rains have brought on some disease but it is too close to harvest to apply any management control and the infestation level remains relatively low.

Significant acreage saw cereal leaf beetle but it appears there will be minimal impact on yield. .

The conditions are still dry despite recent rains. This means the potential for field fires is considered high. Everyone should be ensuring equipment is well maintained, clean, and being very observant. Keep looking behind; don’t get to the end of 1500-2000 ft. field and turn around to face a wall of fire. Rapid response to a field fire rapidly is key. Don’t park pickups and other vehicles with low clearance in the stubble.

Spring Cereals
The crop has struggled with the delayed planting and dry conditions during its early growth stages. There are reports of army worm (Essex County) so producers should be scouting their fields. There is still a window for control, but watch the days to harvest on pesticide labels.

There will likely be some added stress put on the spring cereal crop if it heads out in the next few days under the very high forecasted temperatures. Adequate soil moisture or rain from thunderstorms will help to mitigate this to some degree.

A lot of canola is planted in areas that are dry and the crop is stressed going into flowering. The more southern areas seem to have adequate moisture, but Bruce, Grey, Simcoe and further north are the areas to watch.

Edible Beans
The vast majority are planted. Planting done late May/early June are at about first trifoliate. More of the crop was planted later as producers waited for some moisture that didn’t come before they decided to seed. Much of the area has now received rainfall which has aided emergence.

The early harvested first cut has been quite slow to regrow because of the dry conditions. The recent rains and anticipated heat will see that growth rebound rapidly next week. Much of the non-dairy hay has now been harvested under decent conditions leading to satisfactory yields and good quality. Second cut on the early fields will likely happen this coming week.

Concerns for alfalfa weevil on the second crop for the most part did not develop. It’s expected that they are currently pupating and will likely be controlled by the next cutting.

Sulphur deposition in parts of southern Ontario have dropped 12.5 per cent since 1990 and there are more frequent incidents of sulphur deficiencies, according to the latest Ontario Field Crop Report. 

It is enouraged to watch for symptoms of sulphur deficiency in alfalfa specifically. For winter wheat, the most recent Ontario research suggests that 10 lbs of sulphur per acre is the optimal rate. However, this varies depending on location. In corn and soybeans, there have been isolated instances of sulphur deficiency to date, largely in light-textured soil. A number of on-farm trials are underway this season to evaluate response to sulphur on all three crops across a range of soils.

The latest crop report covers sulphur uptake, impact of soil type and guidelines for Ontario field crops, so producers can identify and manage fields that are most at risk of sulphur limitation. | READ MORE

Kier Miller of Sussex Corner, N.B., said he was “speechless” when he found out the New Brunswick Soil and Crop Improvement Association had named his operation the province’s 2017 farm of the year. Miller Farms comprises 23 acres, nine of which are cleared, with the remainder in woodland. They also lease 180 acres. On top of that, the Millers do custom planting of corn, soybeans, wheat, oats, and barley for other area farmers each year totalling about 1,200-1,500 acres. In the fall, they do about 1,500 acres of combining for others, although not necessarily the same crops they planted. | READ MORE

While applying fertilizer at the time of seeding has many benefits, it is important to use the right amount. Mark Cutts, crop specialist at the Alberta Ag-Info Centre, evaluates placement, impact, and types of fertilizer. “Applying too much fertilizer with the seed can impact crop emergence,” says Cutts. “To ensure seed-placed fertilizers are being managed properly, producers need to understand the factors that influence their impact.”
Pastures and hayland were stressed last year due to dry conditions, grasshoppers, over grazing, and a long winter. Barry Yaremcio, beef and forage specialist with Alberta Agriculture and Forestry looks at how producers can plan this spring to avoid a feed shortage next winter. “It is difficult to estimate how the stands will respond this spring or what the yield potential is for this year,” Yaremcio says. “With many feed yards and silage pits nearly empty or empty, the amount of carryover feed for the winter of 2018-19 is minimal.”

It was the best of times and the worst of times. The year of 2016 was certainly one of the worst of times for Fusarium head blight (FHB). High FHB incidence and severity was widespread across the Prairies, with durum wheat hit especially hard. By contrast, 2017 saw much lower levels of FHB across the Prairies. The difference?

Times change and so do cropping practices, but century-old cropping system experiments continue to give back, thanks to the foresight of researchers who established and maintained the plots for more than 100 years. A recent analysis of nitrogen (N) inputs and removals found a surprising result in a long-term study in Lethbridge, Alta. Nitrogen removal in three different wheat rotations could not be solely attributed to N fertilizer or mineralization.
Better winter field survival is a central goal of Prairie winter wheat breeders. However, over the last few decades, making gains in this trait has been very challenging. So a team of researchers is deciphering the genomics of winter survival to further advance the development of varieties that survive and produce good yields no matter what the winter weather is like.

Like most crop diseases in 2017, infestation levels and severity of stripe rust were low, because of the warm, dry weather that occurred in many parts of Alberta and Saskatchewan. Going into 2018, the risk of stripe rust developing in Alberta will depend on the spores blowing up from the United States.

Until recently, iron (Fe) deficiencies in field crops in the prairies were mostly unheard of until soybean acreages began to expand. In Saskatchewan, with the growing acreage of soybeans, iron deficiency chlorosis (IDC) began to show up in some soybean fields under certain soil and environmental conditions.

Rust is one of the issues targeted in a major project to advance disease management in fall rye. Not only is this project breaking new ground by breeding for rust resistance in western Canadian rye cultivars, but the research could also help shed light on some of the basics about this little-studied disease problem on the Prairies.

According to Angela Brackenreed, an agronomy specialist for the Canola Council of Canada, seed losses during canola harvest are often higher than producers might think – about two bushels per acre on average, but can reach double digits in in extreme cases.

High-yielding crops require large amounts of water during the growing season. A healthy, high-yielding wheat or canola crop requires up to 480 millimetres (mm) or 19 inches of water during the growing season. A good, average crop will take up 300 mm (12 inches) of water from the soil over the course of the growing season, which works out to about 2,718,000 lb/ac of water over the growing season.
