To investigate the possibility of using silver nano-particles for protection of a living organism, wheat seeds were nano-coated and planted. Effect of nano-treatment on seed germination and protection against fungi was compared with that of a conventional preplanting fungicide (Carboxitiram). Influence of soil conditions on the effectiveness of nano-seed treatment was also investigated. Soil conditions included different levels of nutrients, pH and moisture content. Results showed that soil conditions do not affect seed protection provided by silver nano-particles against fungi, and this effect is completely independent of soil conditions. Data analysis indicated that silver nano-particles do not reduce seed germinability. Moreover, seed protection afforded by silver nano-particles and Carboxitiram was not significantly different. Thus, nano-coating may be considered as potential preplanting fungicide.


Key words: Silver nano-particles, seed treatment, preplanting fungicide.
