The lemon grass oil extract was microencapsulated using
sodium alginate. The prepared microcapsules were analyzed
using a light microscope to determine the structure of
microcapsules (figure 2). The lemon grass oil extract was tested
for its mosquito repellency efficiency. The results are presented
in table 1. The results indicate that the fabric treated with
microencapsulated extract by pad dry cure method has the
highest mosquito repellent activity compared to fabric treated
with the extract by wet type dip method
