As alluded to earlier, it is evident that most people are unaware that plants are susceptible to virus infection. This may partially be because one does not hear corn plants sneeze or see boxes of tissues in a potato field. As with many human diseases, early plant (viral) disease outbreaks were often attributed to mysterious entities or unhappy deities and attempts at disease control were essentially based on pleasing the gods. This may sound derogatory towards early civilization, but even today there are virus deniers among us that resist to believe in biological causes. These latter contemporaries are in fact more intellectually challenged than our antecedents who really had no other information and thus were managing their environment within a non-scientific framework (they literally did not know better, in contrast to present-day deniers).
