Insect Pests of Alfalfa

Very little alfalfa is grown in Mississippi, and we do not maintain insect control recommendations for alfalfa. Producers who are attempting to grow alfalfa in the state may wish to refer to the Alfalfa Insect Management Guide, 2014, from Kansas State University, to learn about potential pests and control options. Be aware, however, that the insect pests that attack alfalfa in Mississippi may differ considerably from that in other states and that insecticides labeled for use in other states may not be labeled for use in Mississippi. For example, products containing chlorpyrifos may not be labeled for use in Mississippi even though they are labeled in other states. Read product labels carefully and verify state registration before treating.

Mississippi has an abundance of bugs, especially in the warmer months. We are all familiar with mosquitoes, bumblebees, and house flies. But I bet there are bugs around your house and yard that you can’t identify. (Photo by Blake Layton)
