Wheat blast was first identified in 1985 in Paraná State of Brazil. It rapidly spread to the important wheat-producing regions of Brazil, Bolivia, and Paraguay and has become a devastating disease for wheat production in this region. Yield loss to this disease can be greater than 75% in severely affected fields.
During Dr. Cruz’s research in Bolivia, the rainy season caused very rough road conditions. Travel up and down the mountainous landscape was treacherous at times.
