Cross Application of Entomopathogenic Fungi Raw Secondary Metabolites for Controlling Fusarium Wilt of Chili Seedlings

Abstract

The research aimed to determine the effect of entomopathogenic fungi raw secondary metabolites on fusarium wilt on chili plants and on growth of chili. In vitro test used a Completely Randomized Design with 5 treatments and 5 replicate and in planta using a Randomized Block Design with 5 treatments and 5 replicatie including control, secondary metabolites of Beauveria bassiana B10, B. bassiana B16, Metarhizium anisopliae M16, dan Lecanicillium lecanii L16. Variables observed included inhibition ability, incubation period, desease intensity, plant height, root length, and phenolic compounds (tannins, saponin, and hydroquinone) content qualitatively. The results showed that secondary metabolites of B. bassiana B10, B. bassiana B16, M. anisopliae M16, and L. lecanii L16 were able to inhibit growth of Fusarium oxysporum f.sp. capsici by 50.62; 50,64; 48,62; 56.62%, respectively, extend incubation periods of 71.05; 73,38; 64.89; and 68.57%, respectively, suppress disease intensity by 99.99; 99.99; 99.99; and 99.99%, respectively, can increase plant height by 15.22; 18.8; 21.14; 21.69%, respectively, increasing the root length by 22.61; 25,71; 26,34; 33.50%, respectively, and can increase the content of tannins, saponins and hydroquinone compounds qualitatively compared to controls. The secondary metabolites of enthomopathogenic fungi could be used as organic control for soilborne pathogenic fungi.

Exploring the Global Trends of Bacillus, Trichoderma and Entomopathogenic Fungi for Pathogen and Pest Control in Chili Cultivation

“…In a related study, Mantzoukas et al (2022) demonstrated the remarkable reduction in aphid populations achieved by Metarhizium brunneum at a concentration of 1 × 10 8 conidia/mL. Furthermore, Soesanto et al (2021) emphasized the role of secondary metabolites from entomopathogenic fungi in mitigating infections of Fusarium oxysporum f.sp. capsici in chili plants.…”

“…capsici in chili plants at more than 48 %. Soesanto et al (2021) Beauveria bassiana Thrips ( Scirtothrips dorsalis ) and mites ( Polyphagotarsonemus latus ) The LC50 values against S. dorsalis and P. latus revealed that the B. bassiana formulation exhibited the highest virulence, with the lowest LC50 values recorded at 1.58 × 10 5 and 5.20 × 10 6 spores mL −1 , respectively. Murugasridevi et al (2021) Metarhizium anisopliae Viruses The secondary metabolites from M. anisopliae demonstrated strong disease suppression by reducing the incubation period, viral disease intensity, and AUDPC by 34.22 %, 77.98 %, and 79.49 %, respectively.…”
