Rice husks is an agricultural residue that produced approximately 400 000 metric<br />

tonnes in Malaysia, annually. Rice husks contain silica that benefit for plant growth.<br />

However, burning is the only method in rice husks management in Malaysia that cause<br />

environmental issues. Therefore, extraction of silica from rice husks with<br />

nanotechnology by using slow gelation and freeze drying method will be conducted.<br />

The objectives of the studies are to produce silica nanoparticles (SNP) from rice husks<br />

and to evaluate its bioefficiency against growth and development of rice blast disease.<br />

In conclusion, rice husks will be produced by using slow gelation and freeze drying<br />

method and the bioefficiency on rice blast disease will be tested based on disease<br />

severity and disease incidence that caused by Pyricularia oryzae.<br />
