Each year I get more questions about mixing the liquid fertilizer, ammonium thiosulphate (ATS) with herbicides. With reductions in atmospheric Sulphur deposits, Ontario research has shown positive yield responses in some crops when Sulphur fertilizers are applied and so it makes sense that farmers are looking at ways to add Sulphur to their crop in an efficient manner. However, my…

Scentless chamomile has a reputation for being difficult to control and a 2019 on-farm research trial evaluated several herbicide treatments. Although 10 treatments provided over 80% visual control of emerged plants, new seedlings continued to emerge several weeks after application resulting in a significant amount of plants at the end of August. In order to significantly reduce the population of…

Summary Some years it’s a pleasure to grow soybeans. Other years producing a crop can be a real challenge. The 2019 growing season will be remembered as being very stressful for those involved in crop production. During this challenging year, Agricorp focused on optimizing resources to ensure that customers had the information they needed and that program payments were delivered….

Corn Significant planting progress was made the end of last week and through the weekend as sunshine and warm temperatures dominated for a string of days. Despite the calendar date and reduced yield potential of later planting, many continued to plant corn noting the competitiveness of returns relative to soybeans. Many areas are reporting corn planting reaching 90-95% of intended…

Corn Progress was made over the last week in areas with lighter textured soils. Those areas now have upwards of 80% of their intended corn acres planted.  However, regions with heavier textured soils such as Lambton, Essex, Niagara and Middlesex have 30% of their corn acres planted. Overall, ~60% of the intended corn acres are planted in the province. With…

  “Do not be cheap. Weed control is an investment into the current and future crops on every field.” That was parting advice from Norfolk and Oxford County farmer Ann Vermeersch at the 2019 FarmSmart Conference in Guelph. In front of 80 farmers and agronomists, I moderated a session with Vermeersch and Steph Kowalski, a Certified Crop Advisor and Lead…

Managing Glyphosate Resistant Canada Fleabane with Cover Crops and Tillage

My colleague Dr. Clarence Swanton (University of Guelph) used to say that based on research he did in the 1980’s, one should not expect to control weeds with cover crops. Their utility was in preventing soil erosion and improving soil health but not in significantly reducing weed populations. However, Dr. Swanton has had to re-think his long held position on…

In, Dealing with Escapes – What will they cost you? , we discussed late emerging weeds and their effect on corn yield.  We also discussed some points to consider beyond the effect the weeds will have on yield and why you might consider a post application.  A post-emergence application can provide you with the opportunity to control heavy weed infestations and reduce…

Previously we discussed the possible benefits of using a pre-emergence soil applied herbicide application in a 2-pass weed management plan.  Those benefits include protecting yield, providing a wider window for a post-emergence application and as a resistance management strategy. In this installment we look at the effect of weed emergence, following a pre-emergence application, on soybean yield and examine the…
