?ST. ALBERT – If you have ever wanted to witness an attempt at a Guinness World Record, then you will want to be in St. Albert, Ontario on August 22 when an attempt will be made to set a record for the most plow blades pulled simultaneously.
When Canadian beef producers sell cattle, they contribute to the national beef check-off. That investment supports work that benefits the broader Canadian beef industry, including market development, consumer demand, public and stakeholder engagement, and research. When beef or beef cattle are imported into Canada, an import levy is also collected. While the structure is not identical in every detail, the principle behind it is straightforward: beef marketed in Canada should help contribute to the programs that support beef demand in Canada. The national check-off paid by producers and the import levy paid on eligible imports are two parts of a broader investment approach. Together, they help ensure that both domestic beef production and imported beef products are connected to the market development work that strengthens beef’s position with Canadian consumers. For producers, the domestic cattle check-off is collected at the point of sale and includes both national and provincial po
Despite our best efforts, sometimes even the best laid weed control plans go wrong! The first thing to remember is that not all weed escapes are created equal. In some cases, weeds can survive because of application timing issues, challenging weather conditions or late flushes that emerge after spraying. However, when weeds aren’t controlled by herbicide applications, herbicide resistance should also be on your radar. A recent survey in Manitoba found that in fields with uncontrolled wild oats, 100 per cent of populations were resistant to Group 1 products, 82 per cent were resistant to Group 2 products, and 82 per cent were resistant to both Group 1 and 2 herbicides. Those numbers show how important it is to take a closer look at wild oat weed escapes. Identifying why your herbicide failed to control wild oats is the first step toward finding a solution. Start by scouting the field to narrow down the cause. Consider factors such as application timing, weather conditions, late flush
This is one of the most difficult questions to answer because there are many things to consider. I also don’t want to be outright negative because we do still have options for sclerotinia management in sunflowers. However, management is the operative word. First of all, sclerotinia head rot infections have an interesting pathway. Spores use dead sunflower florets, plus pollen, as the base to infect a sunflower plant. The spores grow into the receptacle, infecting and decaying the entire head after a period of time. Sclerotinia wilt (basal stalk rot) and mid-stalk rot are also infected by the same sclerotinia species, but it will be via the mycelia that grow from the sclerotia bodies in the soil for basal stalk rot. Mid-stalk rot is also infected by ascospores, but this can be earlier in the season than head rot or at the same time. So, management of sclerotinia does not start at flowering. Crop rotation is the most obvious management tool that we are familiar with in sunflowers, but
Packing plants use a time-tested approach to clean their facilities. The first step uses high-pressure hot water to remove fat and meat scraps from equipment, floors and walls. Next, surfaces are cleaned using detergent. Finally, sanitizers are used to further reduce bacterial numbers. Processing companies want to reduce water use as part of their environmental goals and to reduce energy bills. High-pressure water and steam can produce aerosols that capture bacteria and spread them throughout the plant. They can then settle on and cross-contaminate clean surfaces long after the cleaning has been completed, which complicates efforts to effectively clean facilities. Biofilms are another problem. Biofilms are colonies of bacteria surrounded by a protective layer that firmly attaches them to surfaces and shelters the bacteria from hot water, detergents and sanitizers. Biofilms are hard to remove and are commonly found in hard-to-reach places. These researchers investigated potential cro
