Results cleared that, in the first season Techno oil achieved the highest reduction after 10 days of application with 100% followed by Biokiller2 with 98.4% reduction in Kafr El-Sheikh. Similarly, in Al-Gharbia region Techno oil had the strongest effect with 100% reduction followed by Biokiller2 with 98.8% at the same time. During the second season after 10 days of exposure, Biokiller2 had the strongest effect with 96.7% reduction in Kafr El-Sheikh region while in Al-Garbia region techno oil had the strongest effect with 100% reduction followed by Biokiller2 with 99.7%.
