To eviilunlc the efficiency of pliylex at concernritlion of 1600 g.

/ ton grain which was dilunlcd with 5 liter of water before spraying, compared with dusting 2 % urea for controlling AMa Bl in stored maizegrain.

Ucsults of the isolation and idcultificetion that the phylex has a asuperior efficiency to prevent the infection with any fungi in to the stored maize grain, While the following fungus : AUernaria alternata, Aspergillus flavus, A.

nigar, Curvataria spp, Cladospariuni spp, Fusarlum moniliforme, Mucor spp, Penicillium spp, Rlilzopus spp,, Trichodenna spp.

and many bacteria, which dose not ideutificd at maize grain in the control treatment.

The highest infection ratio in maize grain was with A.

flavus which reached 54 % and 68 % in control treatment at 14 % and.

21.6 % relative humidity respectively followed by F.

moniliforme at a ratio of 20.85 % and 35.66 % for the same percentage relative humidity respectively.

A.

nigur, Penicillium.

spp.

and other fungus were found at less ratio treated maize garins.

Spraying Phylex and dusting with 2 % urea significantly reduce the percentage of the contamination with Afla Blwhich is studied by HPLC.There was a significant differences between phylex and urea as compared with control.

Phylex reduced the percentage of contamination With Afla Bl from 20.30, 60 ppm to (10.05,19.29, 33.02) and (11.65, 20.58, 42.86) ppm for both level of relative humidity respectively after one month storage, While urea reduce the same level mean above to (12.38, 20.83, 41.98) and (14.63, 21.17, 46.19) ppm for both level of relative humidity respectively for the same period.
