“…Campuran esktrak daun Mansoa alliacea dan Allamanda cathartica (2:1) mampu menghambat pertumbuhan cendawan A. rofsii penyebab penyakit busuk batang pada tanaman kedelai secara in vitro dengan daya hambat sangat kuat (Parwanayoni et al 2019). Kedua tanaman tersebut mengandung senyawa aktif fenol, flavonoid, steroids, dan triterpenoids yang berpotensi sebagai anticendawan dan antibakteri (Gunda dan Aanandhi 2021; Sarkar dan Mohan 2022).…”

Potensi keanekaragaman hayati flora di Indonesia belum dimanfaatkan secara maksimal sebagai pestisida nabati yang ramah lingkungan, dan mengurangi penggunaan pestisida sintetis pada tanaman. Daun Mansoa alliacea dan Allamanda cathartica memiliki potensi sebagai pestisida nabati karena secara in vitro mampu menghambat Athelia rolfsii, penyebab penyakit busuk batang pada tanaman kedelai. Penelitian dilakukan pada skala lapangan untuk menguji formula aplikasi ekstrak daun M.allicea dan A. cathartica yang berpengaruh terhadap perkembangan penyakit busuk batang, pertumbuhan dan produktivitas tanaman kedelai. Tahapan penelitian meliputi: ekstraksi, pembuatan formula dengan mencampurkan ekstrak daun M.allicea dan A. cathartica, aplikasi formula pada tanaman kedelai, pengamatan, dan pemanenan. Formula ekstrak 1.5% daun M. alliacea dan A. cathartica direkomendasikan untuk diaplikasikan karena dapat menekan penyakit busuk batang, meningkatkan pertumbuhan tanaman dan hasil panen di lapangan.

“…Legume crops are often attacked by stem rot diseases which potentially decrease production and lead to economic losses (Devi et al, 2017;Parveen et al, 2017;Parwanayoni et al, 2019). According to the BPS (2020), Indonesia has continued to import soybeans for the past 20 years, hence, imported soybeans have dominated food processing of raw materials such as tempe.…”

Efforts to improve food security in Indonesia, especially in Bali, need to be supported by improvements in cultivation techniques, including the management of pests and diseases. Legume crops are often attacked by stem rot diseases which can cause decreased production and economic losses. This disease is generally caused by the soil-borne pathogenic fungus Sclerotium rolfsii or Athelia rolfsii. The macroscopic and microscopic morphologies of the two species of the fungus Sclerotium rolfsii and Athelia rolfsii are the same and difficult to distinguish, so molecular identification is needed to determine the species. The research aims to isolate and molecularly identify fungi that cause stem rot disease in local legume plants in Bali. Research methods include isolation of pathogenic fungi from legumes showing symptoms of stem rot disease in Bali, pathogenicity test, identification of the highest levels of virulent isolates, DNA extraction, DNA amplification by PCR, and electrophoresis, ITS region sequencing, and computer analysis sequences DNA. The results of isolation pathogens that cause stem rot disease in Bali's local legume plants obtained six fungal isolates coded SKT, SKB1, SKB2 SKB3, SKL and SKN isolates. SKT isolates had the highest virulence rate after the pathogenicity test of peanut plants. Molecular identification results show that SKT isolate is Athelia rolfsii, because it's in a clade with Athelia rolfsii fungi sequences in GenBank with 100% Bootstrap support.

“…The concept of synergy in botanical pesticides has been explored widely on insects, fungi, animalcules and ants, with positive observations (Huang et al, 2014;Melo et al, 2020). A combination of extracts of Mansoa alliacea and Allamanda cathartica was more effective in inhibiting the growth and spore germination of Athelia rolfsii, the causal agent of stem rot disease in peanut than the individual extracts (Parwanayoni et al, 2018). Species of pepper when combined with Acarus calamus and Coscinion fenestratus were reported quite effective against Alternaria brassicicola, Colletotrichum capsici and Fusarium oxysporum f. sp cubense in different ratios and concentrations (Rueangrit et al, 2019).…”

Tomato (Solanum lycopersicum L.) is affected by many fungal diseases and farmers rely on synthetic pesticides for management. Detrimental effects associated with injudicious use of chemical pesticides have caused a demand for alternative crop protection products. The objective of this study was to evaluate the antifungal activity of selected spices against major fungal pathogens and blight diseases of tomato. An ethnobotanical survey for ginger and turmeric and evaluation of awareness of botanical pesticides use and collection of commonly consumed spices was conducted in Tanzania. Ethanolic extracts from spices were prepared by maceration and tested for antifungal activity in posisoned food bioassay against Phytophthora infestans, Alternaria solani, Fusarium oxysporum f.sp. lycopersici and Pythium spp in vitro, their effect on seed germination and efficacy on severity of early and late blight diseases of tomato in. The most active extracts were fractionated in solvents with varied polarity, analyzed for biochemical composition and tested for fungicidal activity. Results indicated that among the tested spices, clove extract was the most active, inhibiting all the fungal pathogens (100%). Combined effect of the most active extracts showed that clove combined with either ginger, black pepper or turmeric inhibited growth of P. infestans (100%). The activity of solvent fractions was lower compared to the crude ethanolic extracts, except for clove fractioned in n hexane which completely inhibited the growth of P. infestans. Therefore, the most active compounds were better extracted in ethanol. Gas chromatography- mass spectrometry analysis of the clove’s n- hexane fraction showed high abundance of eugenol (74%) which is likely to be responsible for the high antifungal activity. High concentrations of the spice extracts deterred and slowed germination but low concentrations stimulated seed germination of up to 98%. Under field conditions black pepper extract reduced severity of late blight by 40% while clove extract reduced severity of early blight by 35% compared to the untreated control. The findings herein are proof of activity of spice extracts under in vitro and field conditions. This study recommends that the most active extracts be considered for development of a broad botanical fungicide for management of fungal diseases of tomato.
