What’s good for wheat growth is good for wheat midge, says research scientist Tyler Wist, of Agriculture and Agri-Food Canada, based at Saskatoon, Sask. What’s more, these tiny pests can cause big issues, even in very low numbers, so scouting is one key aspect of management. In this edition of RealAgriculture’s Wheat School, Wist also… Read More
Wheat midge is still a significant threat to wheat in Western Canada. While the threat has subsided a bit because of the discovery and use of the SM1 resistance gene, it’s important to remember that there is only one bullet in the chamber, and if it gets spent wheat crops will be, once again, at… Read More
SeCan recently discovered that the majority of the soft white wheat varieties grown in western Canada naturally contain the Sm1 trait for midge tolerance. The trait has likely always been there, but only recently have we had the technology to test for it. The Sm1 gene was first identified as naturally occurring in soft red winter… Read More
By Karen Lewis As farmers across the central U.S. corn belt scramble to prevent the spread of western corn rootworm resistance to Bt corn, Prairie wheat growers are being urged to be diligent in their stewardship efforts to protect midge tolerant wheat technology. “Resistance to corn rootworm technology is really a cautionary tale for Prairie… Read More
The wheat midge (Sitodiplosis mosellana) is a pest found in wheat that can have significant impacts on your yields and grain quality. These insects overwinter as larvae and emerge as adults from their pupal stage in late June to early July (typically 600-900 growing degree days (GDD), ask your agronomist how many GDD`s we have… Read More
In recent years, wheat midge has caused yield losses to fields across the prairie provinces, and has been blamed for wheat quality losses as well, including: aborted kernels, feeding lines and bran rupturing. So we know wheat midge is a significant pest, but did you have any idea that once anthers are present, the plant is no… Read More
What, indeed. If you just read the title and aren’t sure, the short answer is nothing. The longer answer, however, is that tram lines may make scouting for insects easier and more thorough, and thus beneficial. Not convinced? Read on. Some insects are predictably found on the edge of the field — like flea beetles,… Read More
If there’s two things I learned from the GIJOE cartoons in the eighties it’s that 1) GIJOE must have a strict catch and release policy because I don’t recall any members of COBRA being killed and they come back every week. 2) Knowing is half the battle!(they said it at the end of every episode)… Read More
The post CWB monopoly environment has opened up a lot of interest in the CPS wheat class. Internationally recognized as having the high yield and good milling characteristics producers and industry are looking for, the wheat class is still quite small in Canada. The addition of AC Conquer VB to the Canterra Seeds line up… Read More
The 2013 wheat midge forecast map is now live on the Alberta Agriculture website, Ropin the Web. This forecast is based on 298 soil samples taken in the fall after harvest. Indications are that wheat midge will be more of a concern for 2013 than it was for 2012. Midge numbers have increased and they… Read More
Wheat midge feeding on kernels can cause significant damage, downgrading the crop and eating into yield. One of the big trip-ups for many farmers is timing a spray application — is anthesis too late? Do you wait for the entire head to emerge? (Hint: Anthesis is getting too late — more on ideal spray timing… Read More
The 2012 wheat crop looks quite good overall but tests so far have flagged some early problems in the crop: wheat midge damage, albeit at very low levels, is being found in samples from many areas of Manitoba not used to seeing the pest. Light bushel weights, a result of low moisture and high heat… Read More
Assessing risk is a crucial part of any producer’s pest control strategy. If you don’t know what to look for or how to look for it, you are setting yourself up for some potentially costly problems. That risk assessment starts with a good knowledge of the previous year including hotspots for activity, and overall movement… Read More
Wheat midge is something that traditionally, farmers in Alberta have not been too concerned about. It was always more of a Saskatchewan issue. Over the past few years however, as we have moved to wetter springs and summers, conditions have changed enough for the pest to become a greater concern. Wheat midge is a pest… Read More
Wheat midge has great impact on wheat growers in many areas. This year will be the first year that farmers will be able to purchase midge tolerant varieties. There are three different varieties right now and more in the pipeline. It is critical that as an industry we properly manage this great new innovation in… Read More
