later in their reproductive cycle may experience a slowing in ear development (“Maize Dwarf Mosaic Virus,” n.d.), while some plants may even become barren (Lipps & Mills, n.d.). It is not uncommon for plants to have shortened upper internodes or an increase in tiller number (“Maize Dwarf Mosaic Virus,” n.d.). Control Maize dwarf mosaic virus can be managed in several ways. One way is the removal of the local population of Johnson grass as this can harbor the disease. It is best if all producers (farmers) in the area participate in this practice or the disease can remain in sporadic plant populations and be spread in the ways described above (Lipps & Mills, n.d.). Another way to help avoid MDMV is by selecting corn varieties that are tolerant of the virus and by planting corn crops earlier in the season to help seedlings avoid key aphid population times (Lipps & Mills, n.d.).
