Description
High soybean prices have caused many growers to seek out intensive management strategies to maximize soybean yield and profit. One of these strategies is the application of the herbicide lactofen (Cobra®) to early vegetative soybeans. Yield increases observed from the application of lactofen were thought to be due to increased branching. However, yield component analysis conducted in 2012 found that lactofen does not cause increased branching when compared to untreated plants. This means that lactofen may increase yield due to other physiological mechanisms. One possible mechanism is the activation or up-regulation of genes in soybeans that help the plants deal with stress during the pod and seed development. Recent evidence also suggests that lactofen application timing is critical to getting a yield increase in soybeans. The purpose of these projects is to determine the physiological mechanisms behind yield increases seen with early-vegetative applications of lactofen to soybeans and help determine how lactofen application timing interacts with maturity groups and other management strategies to increase soybean yield.
