Monsanto Company will introduce new Genuity Roundup Ready 2 Yield soybean varieties with aphid tolerance in 2011 to help protect soybean yields from these damaging pests.
Since their identification in 2000, soybean aphids have become a major pest in soybean fields throughout the Northern United States. When left untreated, these insects can multiply rapidly and cause significant yield losses. They feed on the sap of the soybeans, leaving behind stunted, curled soybean plants which lead to reduced pod set and seed size. Feeding also potentially transmits harmful viral diseases.
"Monsanto's new aphid tolerant soybeans will be introduced initially in maturity groups I and II in the upper Midwest, the areas where aphid populations are typically the highest," said Aaron Robinson, Monsanto soybean traits technical manager.
