The effect of various essential oil and solvent additives on the botanical pesticide of Piper Aduncum essential oil on formulation antifungal activity

Antifungal effectiveness of some essential oils and their mixtures against Fusarium oxysporum f.sp cubense that causes fusarium wilt disease of banana plants

“…The main components in citronella essential oil (C. nardus) are 41.74% citronellal, 14.89% graniol, 9.86% citronellol, 4.83% naphthalenol, 2.88% limonene, 1.06% citral, and 45% other components [13]. The active compounds that have great potential as antifungals in citronella oil are citronellal, linalool, α-pinene, β-pinene and methone, while geraniol, citral, and terpenes have moderate antifungal activity [23].…”

“…Citronella oil with the main components of citronellal, 41.74%, graniol 14.89%, citronellol 9.86%, naphthalenol 4.83%, citral 1.06% and other components [13], has the potential to be utilized and developed as a botanical pesticide to control plant diseases. Citronella essential oil at a concentration of 2000 ppm for all clones (G1, G2 and G3) was able to suppress the growth of Sclerotium rofsii 100% and Fusarium oxysporum 87.18% which causes wilting and stem rot of chili plants [14].…”

Effect of various formulations of Piper aduncum botanical pesticide and concentration levels on fungal pathogen Fusarium oxysporum f.sp. cubense Vegetative Compatibility Group (VCG) 01213/16 Tropical strain 4 and VCG 01218 strain 1

“…The results showed that the higher the concentration, the higher the inhibition occurs. [10] state that the higher the concentration level, the higher the effectiveness of secondary metabolite compounds so that the inhibition will be more potent. [14] explained that antimicrobial activity will work to inhibit nucleic acid synthesis, cell membrane function, and energy metabolism.…”

“…The powdery extract of P. aduncum forest fruit was reported to control the larvae of the horned beetle Oryctes rhinoceros L. on oil palm with a mortality rate of 92% and an average initial time of death of 12 hours [9]. The concentration of P. aduncum leaf powder suspension with Trichoderma harzianum 100 g/l water can inhibit up to 33.87% of the growth of the fungus Phythopthora palmivora, the cause of cocoa fruit rot in invitro [10]. Another study conducted by Ritonga et al 2017 [11] states that P. aduncum extract can inhibit up to 37.53% of the growth of Aspergillus sp.…”

Effect of doses fertilizer and harvest interval on the intensity of leaf spot diseases, production and quality of citronella grass (Cymbopogon nardus L.) essential oils in ultisols soil

“…Furthermore, citronella essential oil with a concentration of 15% has an effective repellency against Culex sp mosquitoes [ 6 ]. Another benefit of citronella essential oil as an additive can increase the Piper aduncum botanical fungicide against the pathogens Sclerotium rolfsii , Pestalotia sp, and Fusarium oxysporum [ 7 ]. Not only citronella oil can be utilized, but the liquid waste from citronella oil distillation can also be used as a botanical pesticide, namely in controlling A. aegypti instar III mosquito larvae for 24 h with an LC 50 of 8.763% [ 8 ].…”
