To control head smut, the best option is the use of resistant corn hybrids; however, the genotypes that were resistant to the disease in 1 year may be susceptible in the following season. The extent of damage depends on the ambient conditions. On the other hand, cultural practices such as crop rotation, principally with leguminous plants, washing and disinfecting agricultural machinery and tools, and maintaining the level of humidity within the accepted range during the early phase of crop development when infections occur, all contribute to reducing disease incidence. With respect to chemical controls, the use of synthetic fungicides such as triadimenol to treat the seeds is recommended; however, an index of control of just 30% is observed
