Abstract
The antifungal activity of selected weed and other plants leaf extract prepared in distilled water and ethanol were tested against anthracnose, the post-harvest disease of papaya (Carica papaya L.) caused by Colletotrichum gloeosporioides. The result from the experiment proved that ethanol leaf extract of weed plant, Lantana camara L.possess significant fungicidal effect on the radial growth of C. gloeosporioides followed by lemon and avocado leaf extract while Mikania micrantha Kunth, Sphagneticola trilobata (L.) Pruski and Cyperus rotundus L. leaf extract gave an insignificant inhibitory effect on the radial growth the fungus. The result of this study showed that Lantana camara leaf extract has the potential antifungal compound to control C. gloeosporioides which is the casual organism of papaya anthracnose.
Highlights
Papaya known as pawpaw (Carica papaya) is considered as one of the most popular fruits among the millions of people in the tropical and subtropical area due to it taste, nutrition value and medicinal use

Summary
Papaya known as pawpaw (Carica papaya) is considered as one of the most popular fruits among the millions of people in the tropical and subtropical area due to it taste, nutrition value and medicinal use. Anthracnose caused by C. gloeosporioides, is the major postharvest disease of papaya in all papaya producing areas in Fiji and as well all around the world. Synthetic fungicides are currently used as the primary means for the control of plants diseases which are used at pre-harvest or post-harvest treatments acting as the main approach to reduce losses from anthracnose. Their use is increasingly restricted due to environmental and public concerns due to its application as alone, combined in mixtures or applied separately in sequence. The study was carried out with the objective of determining the in vitro effect of plant extract on the radial growth of C. gloeosporioides
