“…To combat microbial diseases, chemical control methods are applied that are irritating, toxic, mutagenic, teratogenic, and carcinogenic to users, as well as having serious ecological consequences. Synthetic chemicals provided promising results against wilt; however, fungicide application under field conditions involves environmental contamination, inconsistency in efficacy, and high costs [11]. The development of resistance of pathogenic fungi towards synthetic fungicides is of great concern.…”

In Vitro Antifungal Activity and Chemical Composition of Piper auritum Kunth Essential Oil against Fusarium oxysporum and Fusarium equiseti

The essential oils of plants of the genus Piper have secondary metabolites that have antimicrobial activity related to their chemical composition. The objective of our work was to determine the chemical composition and evaluate the antifungal activity of the aerial part essential oil of P. auritum obtained by hydrodistillation on Fusarium oxysporum and Fusarium equiseti isolated from Capsicum chinense. The antifungal activity was evaluated by direct contact and poisoned food tests, and the minimum inhibitory concentration (MIC50) and maximum radial growth inhibition (MGI) were determined. The identification of oil metabolites was carried out by direct analysis in real time mass spectrometry (DART-MS). By direct contact, the essential oil reached an inhibition of over 40% on Fusarium spp. The 8.4 mg/mL concentration showed the highest inhibition on F. oxysporum (40–60%) and F. equiseti (>50%). The MIC50 was 6 mg/mL for F. oxysporum FCHA-T7 and 9 mg/mL for F. oxysporum FCHJ-T6 and F. equiseti FCHE-T8. DART-MS chemical analysis of the essential oil showed [2M-H]− and [M-H]− adducts of high relative intensity that were mainly attributed to eugenol and thymol/p-cimen-8-ol. The findings found in this study show a fungistatic effect of the essential oil of P. auritum on Fusarium spp.

“…Tapwal et al (2015) found that T. harzianum recorded maximum growth inhibition (34.20%) against A. alternata, followed by F. oxysporum (27.04%), (15.00%) and minimum for Rhizoctonia solani J.G.Kühn (5.10%). Bhat et al (2016) reported that T. harzianum inhibited mycelia growth by 40.00 to 50.00% in vitro and increased yield up to 30.00% in the Haveri District, while at Bellary, T. harzianum reduced wilt incidence by 39.70%.…”

Abstract. Roy K, Khan AA, Rubayet MT, Haque MM. 2022. Production of quality seeds of chilli using soil amendments. Asian J Agric 6: 7-14. The present investigation was conducted to produce quality chilli seeds using soil amendments. The soil was amended with vermicompost, colonized Trichoderma, mustard oil cake, cow dung, and poultry manure for quality seed production. The fruits yield (3.63 t ha-1) and seed yield (2.40 t ha-1) were higher from colonized Trichoderma amended plot. All the organic amendments such as colonized Trichoderma, vermicompost, poultry manure, mustard oil cake, and cow dung increased the yield of chilli seeds compared to the control. Quality characters of harvested seeds such as germination, vigour, 1000 seeds weight were found higher in colonized Trichoderma amendment plots. Five fungi, namely Aspergillus sp., Fusarium sp., Colletotrichum capsici (Syd. & P.Syd.) E.J.Butler & Bisby, Curvularia sp., and Alternaria alternata (Fr.) Keissl. were found to be associated with seeds and the infection rate of different fungi varied from 1.70 to 9.20%. The lowest (9.80%) total seed-borne infection was also recorded in seeds of colonized Trichoderma amended plot. The highest (3.73) benefit-cost ratio was obtained from colonized Trichoderma, followed by poultry manure (3.39) and vermicompost (3.33) amendment. Thus, soil amendment with colonized Trichoderma or vermicompost or poultry manure is suggested to produce quality chilli seeds with a higher yield.

“…Trichoderma releases diverse secondary metabolites, such as gibberellins, indole-3-acetic acid, siderophores, etc., into the soil surrounding the roots. These substances could potentially contribute to enhanced plant growth while minimizing disease susceptibility Zhou et al, [25] Bhat et al [26] previously tested the effect of T. viride under field conditions at two different places on the incidence of fusarium wilt of chilli and reported that the treated plants recorded reduce incidence of disease (10.8% and 38.5%) in both the seasons. On a similar note, Trichoderma spp.…”

Chilli is an important spice cum vegetable crop from the Solanaceae family grown around the world for its pungent flavor. Fusarium wilt of chilli is one of the most important diseases as it drastically reduces the yield. In the present experiment a total of 4 different botanical extracts and 4 isolates of Trichoderma were evaluated against the growth of wilt pathogen Fusarium solani. Among them neem oil and Tr1 isolate of Trichoderma recorded better results hence they were selected and further studied under pot culture conditions alone in combinations with panchagavya on the incidence of Fusarium wilt of chilli in local variety of chilli Out of 7 different treatments tested, highest germination (93.24%) was recorded from T7. And, highest percent disease inhibition of Fusarium wilt (69.56%) was recorded from T7. On a similar note, plant growth parameters such as improved plant height, dry weight, no. of flowers/ fruits per plant and fruit length were recorded from plants treated with T7. It was clear the IDM strategies perform better in reducing disease as compared to that of chemical control besides improving yield and growth of treated plants.
