Most often in the mid-Atlantic region, pastures are comprised of cool season perennial forages – including, but not limited to, orchardgrass, bromegrass, fescues, timothy, ryegrass, birdsfoot trefoil, red and white clover. Commonly, these forages thrive in the cooler temperatures and shorter days, causing grazing livestock producers to be faced with slow-growing, unproductive pastures during the hot summer months.

With many producers faced with the possibility of replant corn, some important decisions may need to be made with regards to controlling the failed crop plants along with the usual weed management considerations. Special consideration must be taken when the corn is herbicide resistant, such as Roundup Ready and Liberty Link hybrids. As usual, the timing of applications is also important.

Reconsideration of delayed pre-emergence and early post emergence herbicide options may be necessary. The weather effects can result in stressed plants with a greater risk to selection and use of certain herbicides.

Last week I covered four important pest species that can cause trouble this time of year. They were black cutworm, cereal leaf beetle, slugs, and armyworm. This week little has changed and I encourage growers to continue to scout for these pest species to determine if they are infesting your fields and if their populations are economically relevant.
