Can winter weeds harbor SCN?

January 26, 2016

As the most detrimental pest to soybeans in the U.S., soybean cyst nematode (SCN) often destroys 30 percent of yields with no obvious aboveground symptoms, according to the University of Illinois Extension. To manage SCN, Syngenta recommends rotating crops, planting SCN-resistant varieties, using a seed-applied nematicide and soil sampling after every second soybean crop. It’s also extremely important to keep fields clean from winter weeds, such as henbit and purple deadnettle, which act as alternative hosts to SCN during the months between harvest and planting. These precautions help maintain the protection offered by genetic SCN-resistance sources.

Syngenta encourages you to develop a proactive management plan to protect your yields from SCN. Clariva® Complete Beans seed treatment, a combination of separately registered products, contains a nematicide, an insecticide and three fungicides, providing crops with triple pest protection during the critical early-growth stages. The nematicide component of Clariva Complete Beans contains a revolutionary nematicide with direct, lethal activity against SCN. A proactive SCN management program that includes a seed treatment like Clariva Complete Beans is essential to protecting your soybeans from increased yield loss and increasing your return on investment.

Additionally, a burndown application of Gramoxone® SL 2.0 herbicide will help your soybeans start clean and eliminate early-season weed competition. Planning for a soybean herbicide application should always include using a broad-spectrum pre-emerge herbicide to protect against weed competition and improve control of tough weeds, helping you grow more soybeans.
