In the present study, we aim to understand the efficiency of turmeric as a potent botanical against the common stored grain pest of legumes, Callosobruchus chinensis. Computer–based in-silico techniques are used as they allow a faster and more precise assessment of drug action. Direct toxicity tests are performed and the results are corroborated with the in-silico simulations to confirm the efficacy of turmeric as a potent botanical in management of C. chinensis.","PeriodicalId":15188,"journal":{"name":"Journal of Biological Control","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86531864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several workers reported that amendments like chitin and ammonium sulphate will enhance the bioefficacy of Trichoderma isolates and shows positive effect on multiplication and storage of Trichoderma sp. In the present studies, an attempt was made to develop the Trichoderma sp. formulations in form of talc, sago, dalia and pellets using bentonite and wheat flour. Ammonium sulphate (0.5% and 1%) and chitin (01%) was used to increase the storage life and multiplication of the Trichoderma sp. Sago and dalia proved to be a good substrate of the bioagent under study in comparison to the conventional substrate talc. Among the amendments in the growth media, 1% chitin may be an effective supplement to the growth media for increasing its survival in storage. The interaction studies between different substrates and amendments selected to increase the shelf life, a combination of sago and 1% chitin was found to be effective for rapid multiplication of Trichoderma isolate.

However, it should not be neglected that synthetic insecticide causes negative impacts on humans, livestock as well as the environment. This review aims to provide data on entomopathogenic fungi species that can be developed into bioinsecticide to control insect pests, in order to reduce the usage of synthetic insecticide. The fungi are discussed based on two criteria, its effectiveness in controlling the targeted pests, and its safety level to humans, non-targeted organisms, and the environment. Relevant data and information on entomopathogenic fungi from various research tools including Google Scholar, NCBI, Science Direct and Researchgate were compiled into tables for comparison and analysed. Six entomopathogenic fungi namely Beauveria bassiana, Metarhizium anisopliae, Verticillium lecanii, Metarhizium (Nomuraea) rileyi, Paecilomyces fumosoroseus and Hirsutella thompsonii are proposed as having the required criteria having potential to control targeted insects by means of producing various toxins or metabolites with insecticidal properties. Five out of the six species, B. bassiana, M. anisopliae, V. lecanii and N. rileyi are safe to humans, non-targeted organisms, and the environment. Furthermore, all these fungi can be mass produced to ensure their availability to be used as a biocontrol agents.

The use of native strains of Trichoderma spp. against plant diseases may help to reduce the dependence on chemical fungicides. In this study, eleven novel isolates of Trichoderma spp. from virgin forest soils of different agro-climatic zones of Kerala were characterized and evaluated for their efficacy against damping off disease of tomato caused by Pythium aphanidermatum under in vitro and in vivo; and also, against wilt pathogen, Fusarium oxysporum under in vitro conditions. Dual culture assay showed that all the Trichoderma isolates were found to inhibit the growth of P. aphanidermatum and F. oxysporum under in vitro conditions with multiple modes of action. The mycelial colour, texture, and conidial characters varied among all the isolates. The volatile metabolites by isolates of Trichoderma spp. also showed in vitro inhibition of the pathogens.

The management of disease through application of fungicide is not feasible and economically viable. Hence, the present study is focused on investigation of effective Trichoderma sp. and identifying the effective volatile organic compounds produced by it against the basal rot pathogen in onion. A total of ten Trichoderma spp. were isolated from rhizospheric soil of healthy onion plants and tested against virulent Fusarium oxysporum f. sp. cepae isolate FCIM1. The Trichoderma isolate (TIM2) showed 77.40% inhibition on mycelial growth of pathogen followed by the isolate (TIV1) with 70.36% inhibition. The molecular identification of effective Trichoderma isolate through the analysis of the rDNA of Internal Transcribed Spacers (ITS) region revealed isolate TIM2 as Trichoderma hamatum. The GC-MS analysis of Trichoderma hamatum unravelled the important volatile organic compounds like Methyl stearate, n-Hexadecanoic, Eicosane, 9-cyclohexy, Heptadecane, Dodecane, 2-cyclohexyl, to 2H-Pyran-2-one, 6-pentyl, 5-Hydroxymethylfurfural, Tetrapentacontane, 1-Dodecanol, 2-Propenoic acid, pentadecyl ester, Benzene, (2-methylbutyl) and 1,2-Dimethyltryptamine with peak area and retention time. These bioactive compounds exert a strong antifungal activity against Fusarium oxysporum f. sp. cepae.
