Mango malformation is a serious disease affecting mango production, causing deformation of floral and vegetative shoots. It leads to significant yield losses.
The historical records indicate that mango malformation was first reported from Bihar, India, in the year 1891 by G. Marshall Woodrow (some sources cite Watt or Maries around the same time). This makes it one of the oldest known diseases of mango in the region.
Therefore, the correct year for the first reporting of mango malformation is 1891.
