Rots in yam tubers are the dominant cause of postharvest losses. Therefore, studies were conducted to identify the rot-causing organisms in yam and to evaluate the efficacy of false yam (Icacina oliviformis) plant extracts as surface protectants in the storage of yam. The experiment was laid out in a completely randomized design (CRD) design with five treatments (fruit, root and leaf extract of false yam, Mancozeb and tap water) replicated three times. Two concentrations (50% and 100%) of each extract were also tested. Species were identified based on the structural features, the characteristics and properties of the spore and mycelium. A spore suspension of yam rot fungi was sprayed on healthy yam tubers that had been pretreated with the extracts. Results showed that fungi isolated from rotted yams were Aspergillus niger, A. flavus and Penicillium sclerotigenum. Leaf extracts (both 50% and 100%) had the highest growth inhibitions on all the three fungi isolated in vitro. Tubers treated with root and leaf extracts of false yam had a decreased tuber rot lengths of 1.80 mm2 and 2.17 mm2, respectively. The leaves and roots of false yam can be used as a surface protectant of yam in place of Mancozeb. Keywords: Icacina oliviformis; Dioscora rotundata; Mancozeb; Pathogenicity; Aspergillus spp.

Bioherbicide is an alternative compound to control weeds which are environmentally friendly by utilizing parts of plant organs, like leaves that are applied in the form of extracts. The aim of this study is to determine the potential of Terminalia catappa, Swietenia macrophylla, and Filicium decipiens leaf extract as bioherbicides against Cyperus rotundus and to find out which leaf extract has the most effective to prevent the Cyperus rotundus growth. The study was done by using maceration techniques of leaf extract with ethanol solvent applied to Cyperus rotundus. This study was designed in a Completely Randomized Design (CRD) consisting of 4 treatments, which are control, 50% of Terminalia catappa leaf extract concentrate, 50% of Swietenia macrophylla leaf extract concentrate, and 50% of Filicium decipiens leaf extract concentrate. The results of this research showed that ketapang, mahogany, and kerai payung leaf extract could be used as bioherbicides because it has a very significant effect on inhibiting the height growth, the number of leaves, and the length of the roots of Cyperus rotundus. Filicium decipiens extract was the most effective extract in inhibiting the number of Cyperus rotundus leaves. However, each leaf extract did not significantly affect the reduction of chlorophyll content and dry weight. Therefore, further research is needed regarding the potential of these three leaf extracts to other weeds.
