Abstract
This research was conducted to evaluate the effect of natural bioactive constituents derived from Chrysanthemum species. The objectives of this study were to evaluate the effectiveness of active ingredients of Chrysanthemum sp. toward the mortality of Plutella xylostella, a major pest of Crucifers family and to determine the effectiveness of Chrysanthemum sp. extract obtained from flowers and leaves part. This study was conducted in a farm owned by local farmer at Kundasang that applied semi control environment agriculture practice. Chrysanthemum sp. was purchased from commercial nursery. The extracts were prepared from flower and leaves of Chrysanthemum species. The extracts obtained were evaluated for their effectiveness against the P. xylostella that attack mustard crop. The concentration applied for the spraying is 2.5% w/v concentration and distilled water act as a control. The extracts were then tested over a time period of 24 to 72 hours. The treatment was replicated twenty times and each replicate contains average of two larvae of P. xylostella. The result revealed that spraying by using Chrysanthemum flower extract was more effective compare to the leaves extract in causing 100% mortality at the first 48 hours of exposure. One way ANOVA showed that there was significant different between different extracts (p<0.05) on the mortality of P. xylostella. In conclusion, this study has clearly demonstrated the usefulness of Chrysanthemum sp. as a control P. xylostella on mustard crop in real field condition.
