Seed is not known to be a pathway. "Basic information on dispersal, overwintering, and survival, and tempera- ture, light, and moisture requirements for this pathogen is lacking. It also is possible that future changes in the genetic base of U.S. maize hybrids could result in an inad- vertent shift toward increased susceptibil- ity and increased vulnerability to PLS."
