The Efficacy of Aqueous Leaf Extract of Akapulco in Vitro of Biological Control on Some Fungal Pathogens in Tomato

Abstract

INTRODUCTION

Researcher selected Cassia alata (akapulko) for a comprehensive review on antifungal activity. The plant can be found widely in tropical regions in Indonesia, Thailand and the Philippines. The aim of this study is to evaluate the antifungal activity of its aqueous leaf extract on plant pathogen.

METHODS

This study used 2 setups, 1 group with 1 fungi component in each concentration. This experiment observed 1 week with the use of zone of inhibition as a method of pouring extraction of Akapulko in the fungi components. Antimicrobial assay was used to determine the antifungal activity of Akapulko.

RESULTS

In the result, the Akapulko leaves extract sample A and sample B showed no inhibition, but on sample A it contained 18% of clotrimazole.

DISCUSSIONS

The zone of inhibition is the measure used in determining the growth inhibiting effect of different extracts and it was noted that the 2 set up showed inhibition; no inhibition of growth of organism but for Set A which contains more plant extract contains 18% clotrimazole. The results have showed that there is chance of treating aspergillus niger in tomato.
