Bacteria as plant pathogens can cause severe economically damaging diseases, ranging from spots, mosaic patterns or pustules on leaves (Figure 5) and fruits, or smelly tuber rots to plant death.
Size of force or number of deaths does not necessarily equate to worst - the question is not what was the largest defeat nor was it what was the defeat with the most casualties. As such, I would suggest that the worst defeat in US military history was the Battle of Little Big Horn, or Custer's Last Stand - a hastily decided attack by Custer left his troops ripe for the picking by the Soux and Apache warriors.
Antietam had the highest casualties in a single day. No battle the  US has ever fought produced so many single day casualties. This  battle had serious consequences.   â¦  For the battle with the most serious consequences, you could pick  either Vicksburg or Gettysburg, which happened on the same day.
