Abstract:
Diseases in rice plants (paddy) caused by microorganisms such as Pyricularia
oryzae lead to a decrease in rice production. Therefore, it is essential to find out
biological agents for protecting paddy and plants in general, against plant
diseases. Liquid smoke and endophytic fungi have been known as biological agents
to enhance the protection of plants against disease. The purpose of this study
was to determine the ability of liquid smoke, endophytic fungi and combinations
to suppress the growth of P. oryzae. The results showed that liquid smoke
concentrations of 0.17% to 1.75% and endophytic fungifiltrateof2% to 10% showed
significant ability against pathogen P. oryzae. However, the combination of liquid
smoke and endophytic fungi filtrateat selected concentrations (0.17% liquid smoke
combined with2% endophytic fungi filtrate and 0.34%liquid smoke combined with
2% endophytic fungi filtrate) showed no significant inhibition percentage against P.
oryzae compared to control. In conclusion, this study showed that the respective
applications of liquid smoke and endophytic fungi filtrate inhibit the growth of P.oryzae.
