Protecting Crop Yields with Postemergence Herbicides

Postemergence herbicides are an important component of today's weed management systems. Herbicides introduced in the past 10 years for use in both corn and soybeans are able to kill much larger weeds than earlier products, thus providing farmers with greater flexibility in application timing. However, this benefit may end up costing farmers money if application is delayed too late into the growing season. This article will discuss the importance of application timing in protecting crop yields.
