Syngenta offers strategies to combat Soybean Cyst Nematodes

Soybean Cyst Nematodes, the No. 1 source of yield loss for U.S. soybeans, are still being seen in significant amounts in the Midwest, according to Syngenta.

Grower reports cited Soybean Cyst Nematodes in all major soybean-producing states.

Steve Boever, a grower in Iowa, planted seed treated with Clariva Complete Beans seed treatment after dealing with Soybean Cyst Nematodes on his soybean plants in the past.

“We have a big issue with nematodes that people don’t realize,” Boever said. “Big roots mean big yields. These have been my best beans in 30 years.”

Soybean Cyst Nematodes attack plants at the root tissue and leave unprotected wounds. The damage at the roots limits the ability of the plant to absorb water and nutrients, causing some plants to die and lowering yield. The nematodes cannot be removed after being confirmed on a field, leading to stunted plants, but they can be managed.

Iowa State University, along with other university extension services, is urging soybean growers to sample their soybean plants because Soybean Cyst Nematodes cannot be seen above ground. The best way to protect soybeans is to rotate with non-host crops like corn, alfalfa and cereals as well as planting with Clariva Complete Beans and Mertect 340-F fungicide.
