Fresh cucumber fruits samples of plastic green house were marketed from eighteen localities representing twelve Egyptian Governorates. Residues of Diniconazole (Sumi-eight), Carboxin (Vitava x200), pyrazophos (Afugan), Fenarimol (Rubigan), and Metalaxyl (Radomil plus) were thoroughly investigated and determined on and in unwashed and washed fruits. Experimental results showed that the residues of Diniconazole and carboxin in samples of all different eighteen localities were either undetectable or loss than maximum residues limits (MRL), except which collected from El-Helmia El-Kadema and Modriet El-Tahrir where the both fungicides residues were more than MRL, the residues of pyrazophos in samples collected from ten locations were more than MRL, while those collected from El-Helmia El-Kadema, Embaba, Dokki, Dikerness, Zagazig, Kom Hamada, El-Arab, and Kena were either undetectable or less than MRL, also the residues of Fenarimol in samples collected from most locations were either undetectable or less than MRL, while those collected from El-Agamy, Benha, and Dikerness were more than MRL, and latter the residues of Metalaxyl in samples collected from most locations were either undetectable or lower than MRL, while those collected from Heliopilies and Rod El-Farag were more than MRL. Therefore, unwashed and washed cucumber fruits samples collected from twelve Egyptian markets as follows: Heliopilies, Bab El-Loak, Rod El-Farag, El-Helmia El-Kadema, Giza, El-Agamy, Benha, Menouf, Dikerness, Modriet El-Tahrir, Fayed, and Minia were not safe for human consumption, while those collected from Embaba, Dokki, Zagazig, Kom Hamada, El-Arab, and Kena can be consumed safely by human.
