The Ontario Corn Committee (OCC), the Ontario Cereal Crops Committee (OCCC), the Ontario Pulse Crop Committee (OPCC), and the Ontario Soybean and Canola Committee (OSACC) launched their new website: GoCrops.ca. The new website brings together the four previous crop committee websites under one cohesive banner. Ontario growers rely on third-party variety performance trial information to […]
Deb Campbell (Agronomy Advantage) notified me of high levels of bean leaf beetle (BLB) and pod feeding in IP and seed soybeans in Wellington, Grey and Simcoe counties. Fields in other counties could also be at risk, given how behind the crop is. BLB can feed on the surface of the pod which exposes the […]
A few pests are starting to show up in fields. If you haven’t had a chance to take a look yet, plan to check those high risk fields that are prone to seeing soybean aphids (soybeans) or western bean cutworm (corn and dry beans) in the next week or so. Soybean aphids: Soybean aphids are […]
Co-authored with Ken Janovicek and Dr. Dave Hooker, University of Guelph Highlights By now, you’ve likely heard the message from the long-term rotation trials at Ridgetown and Elora: winter wheat in rotation improves corn and soybean yields. But with greater revenue coming in during corn and soybean years, the real question is whether these yield […]
Most springs, conversation at some point turns to no-till soybeans and how tough they look compared to their tilled counterparts. 2022 was no exception. With a record corn crop in 2021 and compaction due to a wet fall, there were challenges to contend with in no-till and some fields did get off to a slow […]
Cereal rye is a versatile cover crop that can be seeded late into the fall in Ontario. Not to be confused with annual ryegrass – a grass that can be challenging to control – it is a winter cereal that overwinters reliably and grows rapidly in the spring. Delayed termination of rye by herbicide prior […]
Growing cover crop-based organic no-till soybeans requires a different system approach than for standard organic production. Three years of extensive research trials in Ontario have guided the development of four key best practices for growing no-till organic soybeans following a cereal rye cover crop. This tip sheet is designed to provide practical advice for Ontario […]
Some areas saw a bit or a lot of rain this past week but likely not enough yet to reduce our risk of spider mites in soybeans and dry beans. What is very concerning is that samples collected last year from 10 fields in southern Ontario all were resistant to dimethoate (Lagon or Cygon). The […]
With some soybean fields in early flowering, it is time to scout fields for soybean aphids. Early planted fields tend to be the first to be colonized. The mom aphids start depositing nymphs in pockets in the field that start to build populations of up to 1000s per plant. Once these pockets of aphids get […]
Reports are coming in that black cutworm larvae are cutting corn and even soybeans. We don’t often see cutting in soybeans but two fields in Niagara region were reported today with significant stand loss and a variety of sizes of larvae (Figures 1 & 2). Fields not treated with an insecticide seed treatment or planted […]
Did you know that a review of Ontario phosphorus (P) and potassium (K) fertilizer guidelines was undertaken? The work looked at crop responses to P and K for corn, soybeans, winter wheat and alfalfa from 368 trials conducted over the last several decades. It compared most economic rates to current Ontario fertilizer guidelines as found […]
In this article, we will take a look at using a roller crimper for organic no-till soybean production and the results of on-farm trials conducted in Ontario from 2019 to 2021. Highlights Why organic no-till? Organic soybean production relies on a significant amount of tillage. When done well, strong yields can be achieved. There are […]
Welcome rains have turned to downpours in some parts of Ontario. In extreme cases, fields have received in excess of 12 inches of rain over a two week period. Excess moisture has resulted in a tremendous number of fields turning yellow (Picture #1). This yellowing is not the result of root rots but largely a […]
Jake Munroe, Mike Cowbrough and Sebastian Belliard (OMAFRA) Cereal rye (Secale cereal) has several strengths as a cover crop option. It’s relatively inexpensive and easy to kill. Rye improves soil structure, builds organic matter and helps protect against water and wind erosion. It can suppress weeds as discussed here (see Figure 1). It’s also very […]
This article was written by Horst Bohner, OMAFRA Soybean Specialist, and Paul Sullivan, Sullivan Agro Inc. White mould can be one of the most devastating soybean diseases growers face. The extent of yield loss is largely dependent on the inoculum “load” of a field and the right weather occurring during soybean flowering. If the disease […]
