Comparative Studies Using Nanotechnology on Fungal Diseases Defense to Productivity Improvement of Squash Crop

Abstract

The objective of this paper was to study the effect of silicon dioxide (SiO2) and titanium dioxide (TiO2) nanoparticles NPs sprayed separate or in combination compare with traditional practices on plant ability to resist fungal diseases and improving growth and productivity of zucchini squash (Cucurbita pepo L.) crop in Al-Kantara Sharq experimental station located 30 o 49' 41.4" N and 32 o 24' 11.4" S, Eastern part of Al-Ismailia governorate within Sinai, Egypt during summer seasons of 2015 and 2016. The treatments were: 1.Control spraying with distilled water (T1), 2.Copper oxychloride Cu2(OH)3Cl at concentration of 5000 ppm (
