This week we would like to discuss tar spot in corn as well as soybean cyst nematode and sudden death syndrome in soybean. Tar Spot in Corn There is a lot of discussion and questions surrounding tar spot this year in Ontario. Tar spot is a new corn disease in the US midwest and since […]
Background Although named for its affliction on soybean plants, soybean cyst nematode (SCN) can cause comparable damage to dry edible bean crops, and can adversely affect yields and economic benefit, as well as the future use of Ontario’s current dry bean-producing land. Poor yields associated with SCN infestation can be exacerbated by other environmental factors […]
Ontario’s dry edible bean producers are top notch farmers. They invest a great deal of time and money in managing this high risk, high reward crop. To keep the scales tipped towards ‘high reward’, dry bean producers need to know the soybean cyst nematode (SCN) status of their fields. SCN is now present in 22 […]
Have you ever had a dry bean crop that looked healthy but resulted in disappointing yields? Have you seen stunted or yellowing patches, but could not identify the cause? If so, you may want to look for soybean cyst nematode (SCN). Researchers in Ontario and the US have shown that SCN is not just a […]
I have had a lot of questions concerning Soybean cyst nematode and rhizoctonia in soybeans recently. In terms of SCN, remember the primary SCN symptom is often no above ground symptoms at all. Growers are advised over the next few weeks to scout for SCN by carefully digging-up plants, gently remove the soil from the […]
Challenges and opportunities for the 2012 soybean crop Soybean acres continue to increase. Shorter crop rotations will mean soybean growers have to be vigilant in selecting disease resistant varieties, scouting their crop, and applying inputs when required to prevent crop losses resulting from short rotations. Soybean Cyst Nematode (SCN) can become a problem in short […]
