Argentina reported its first finding of Asian soybean rust last week in the Entre Rios province.
Currently, Entre Rios soybeans are more vulnerable to damage given that much of soybeans are in the flowering stage of development.
Entre Rios' soybean production accounted for 8% of Argentina's total production last season.
The scourge is also affecting the eastern province of Entre Rios and Chaco in the north.
