Abstract
This study was conducted in a number of extension centers in the governorates of Iraq (Anbar, Baghdad, Babil, Al-diwaniyah, Dhiqar, Kirkuk, Salah al-Din, and Wasit) with the aim of spraying nano- and regular urea and fungicide Zoxis 250 g / L at the stage of physiological maturity to prevent the fungus Aspergillus flavus from producing aflatoxin B1 and Reducing it, as the results showed the efficiency of nano-urea in reducing the moisture content, as it reached 22.37% (before storage) and 8.29% (after storage), compared to distilled water, which gave the highest moisture content in grains, reaching 35.51% before storage and 15.75% (after storage). The results showed that nanourea achieved high efficiency in reducing aflatoxin in Salah al-Din Governorate, reaching 99.39 parts per billion, while Anbar Governorate recorded the lowest aflatoxin reduction rate, reaching 90.36 parts per million. The fungicide and regular urea treatments also achieved clear significant differences compared to the control treatment, with a lower reduction percentage compared to the nuclear urea treatment.
