The present study was undertaken to evaluate the mosquito-repellent property of marigold flower based cakes using natural binders. Marigold flower cakes were prepared using different natural binders such as neem powder, wood powder, coconut shell powder and cow dung and were impregnated with extracted marigold flower oil of different concentrations, i.e. 0%, 5%, 10% and 15% using methanol as a carrier alcohol. The evaluation of mosquito repellent activity was carried out based on 3 parameters â flammability, burning efficiency with respect to burning time and mosquito repellent activity of the cakes. The results showed that marigold flower cakes with neem powder as a binder; impregnated with 15% marigold oil has the most effective repellence activity. From the present study it can be concluded that marigold flower-based cakes can be used as potential repellent against mosquitoes.
