Comparative the efficacy of sodium metasilicate with silica nanoparticles against Spodoptera Lirroralis(Boisd.) in the laboratory [electronic resource].

Includes references.

The current experiment was conducted at the Plant Protection Research Institute (PPRI), Sakha Agriculture Research Station (SARS). In this study, the effects of sodium metasilicate and silica nanoparticles on the mortality of cotton leafworm, Spodoptera littoralis (Boisd.) larvae were studied in addition some biological aspects. The results showed that, the silica nanoparticle was more effective at all concentrations than sodium metasilicate. Increase the sodium metasilicate or silica nanoparticles concentrations showed adverse effects on the cotton leaf worm biological aspects especially at the high concentration. Silica nanoparticles showed easily absorption in soybean plants, so it highly effective on cotton leafworm survival and biological aspects. This study pointed to that, silica nanoparticles can be used as a safety agent for controlling S. littoralis through a I.P.M.
