Soybean aphids don’t always cause a problem thanks, in part, to effective control products. But aphid numbers are cyclical despite good control and additional control is sometimes needed. That said, the pest can be kept in check with high populations of beneficial insects present, making scouting and re-scouting a critical means of protecting the soybean… Read More

Damage from soybean cyst nematode can be minor, but once this pest is established in a field, it’s there for good. Since being confirmed in Ontario about 15 years ago, the nematode moved throughout much of the soybean growing region. Knowing the nematode pressure level in your fields is essential to minimizing damage through the… Read More
We’ve talked about the importance of pre-plant control of Canada fleabane, and how to avoid letting this weed get a foothold in your field, but what are your options when it is there? There are several options, but the effectiveness of both tillage or herbicides is influenced by many factors. Tillage is only about 70%… Read More
Towering yellow-flowered plants in a soybean field don’t just look a bit out of place, these volunteer canola plants are actually competing with the crop and using valuable soil nutrients. Just how much of an impact this has on final soybean yield is important to know, as, just like with any pest, it’s important to… Read More
Inoculating soybeans properly and with the appropriate product is one of the top two important decisions that factor into the success of the crop (variety selection for your region is the first). A 40-bushel an acre crop will require roughly 200 pounds of nitrogen per acre — properly inoculated soybeans will fix the lion’s share… Read More
The advent of glyphosate resistant weeds has and will continue to complicate pre-plant weed removal. Farmers need to match herbicide resistance management and control options with targeted weed species to ensure not only an effective kill, but also to avoid limiting control options later. Glyphosate-resistant giant ragweed has been confirmed in Ontario, and farmers set… Read More
Canada Fleabane can be the menace of menaces in your soybean crop IF you don’t hammer it down early. The truth is that the weed is so hearty — between its resistant characteristics and its ability to firmly root itself down — if you don’t deal with it while it’s young, you’ve got a problem… Read More
As more Manitoba farmers add soybeans into the crop rotation, it stands to reason that pests that attack the crop will begin showing up as well. Root rots — and there are so very many species that cause this — already exist in prairie soils, but just which species are here and what to do… Read More
When any crop disease makes it’s way into new territory, one of the most important steps in keeping it under control is being able to diagnose and identify it. That’s precisely the situation soybean producers find themselves in with Soybean Vein Necrosis Virus. The virus is fairly new on the scene in Ontario and it’s… Read More
Fall is a great time to do a few things: soil test, research soybean varieties for next year and test for soybean cyst nematode (SCN). The three tasks can actually be done simultaneously. As Albert Tenuta, field crop plant pathologist with OMAFRA, explains in this video, now is a great time to test for SCN…. Read More
