Abstract

This research includes isolation of flavonoid Torosflavon D from Cassia Torosa, mediaformulation for pathogenic fungi growth, regeneration of pathogenic fungi, and bioactivity test of theisolated flavonoid on some pathogenic fungi. The flavonid bioactivities tests indicate that theTorosflavon D (5ppm) only effective to inhibit the radial growth of Fusarium oxysporum fsp.Lycopersici (48.75%). Statistical test (anova) indicates that concentration of the flavonid significantlyinhibit the fungi radial growth. Duncan test proves that 5 ppm concentration of Torosflavon D 5inhibits the growth of Fusarium oxysporum fsp. Lycopersici colonies optimally.

Abstract

This reserach aims to develop a new fungicide formula with active agent Eusiderin I toinhibit Fusarium oxysporum f.sp. lycopersici that causing fusarium wilt on tomato. This researchincludes isolation Eusiderin I from bulian wood, growing potato in green house, reproduction ofFusarium oxysporum f.sp. lycopersici, eusiderin I stability test, bioacitivity test of the Fusarium in agreen house. This research succesfuly formulates an emulsifiable concentrate fungicide with activematerial Eusiderin I. The fungicide formula is composed of active material, solvent, and emulsifier.Eusiderin I 3 ppm proves the highest efication, indicated by only a tomato plant dead in eachtreatment (p<0.05). It was concluded that . fungicide with active content Eusiderin I on 3, 4, and 10ppm affect on the number of survived tomato plants. The efication degree of this fungicide on 3, 4,5, and 10 ppm is not significantly different.
