“…Although M. circinelloides is a well-known phytopathogen ( Medina-Córdova et al., 2016 ), members of the Trichoderma genus are popular for their protection activities and represent global distribution as plant endophytes. Moreover, they are well-known antagonists for pathogenic fungal species and also act as plant growth promoters ( Cuervo-Parra et al., 2022 ). Trichoderma have been used to manage many diseases and hence are commercially available biological control agents.…”

Fusarium oxysporum has been reported to be the most devastating pathogen of Crocus sativus L., a commercially significant crop that yields the saffron spice. However, most of the pathogen isolations have been done from the diseased tissue, mostly from rotten corms, but no study has been conducted on diseased saffron fields. To fill the knowledge gap, the current study was carried out with the intention of recording the diversity of cultivable fungus species from saffron fields and screening them for pathogenicity towards saffron. The three study locations in Jammu and Kashmir, Srinagar (Pampore), Kishtwar, and Ramban, yielded a total of 45 fungal isolates. The internal transcribed spacer (ITS) of rDNA was used for the molecular identification. ITS rDNA-based sequence analysis classified all the operational taxonomic units (OTUs) into two phyla—Ascomycota (88.88%) and Mucoromycota (11.11%). Moreover, Fusarium (57.77%), Geotrichum (17.77%), Mucor (11.11%), Aspergillus (4.44%), Trichoderma (4.44%), Galactomyces (2.22%), and Colletotrichum (2.22%) all had different total abundances at the genus level. It was discovered that the saffron fields in Srinagar have fewer varied fungal species than the other two selected sites. All of the fungal isolates isolated including Fusarium solani, Aspergillus flavus, Trichoderma harzianum, Fusarium neocosmosporiellum, and Mucor circinelloides were pathogenic according to the pathogenicity test; however, injury to the saffron plant was found to be a must. These fungi were pathogenic in addition to F. oxysporum, which is well documented as a major cause of saffron corm rot diseases in Srinagar, but in the present study, injury was a must for F. oxysporum as well. The percentage disease severity index for both saffron roots and corms varied for each fungal isolate.

The present work investigated the potential of fungal species from grain maize farms in Malaysia as antagonists against the indigenous mycotoxigenic fungal species and their subsequent mycotoxin production. Dual-culture assay was conducted on grain maize agar (GMA) with 12 strains of potential fungal antagonists namely Bjerkandra adusta , Penicillium janthinellum , Schizophyllum commune , Trametes cubensis , Trichoderma asperelloides , Trichoderma asperellum , Trichoderma harzianum , and Trichoderma yunnanense against seven mycotoxigenic strains namely Aspergillus flavus , Aspergillus niger , Fusarium verticillioides , and Fusarium proliferatum producing aflatoxins, ochratoxin A, and fumonisins, respectively. Based on fungal growth inhibition, Trichoderma spp. showed the highest inhibitory activity (73–100% PIRG, Percentage Inhibition of Radial Growth; 28/0 I D , Index of Dominance) against the tested mycotoxigenic strains. Besides, B. adusta and Tra. cubensis showed inhibitory activity against some of the tested mycotoxigenic strains. All fungal antagonists showed varying degrees of mycotoxin reduction. Aflatoxin B 1 produced by A. flavus was mainly reduced by P. janthinellum , Tra. cubensis , and B. adusta to 0 ng/g. Ochratoxin A produced by A. niger was mainly reduced by Tri. harzianum and Tri. asperellum to 0 ng/g. Fumonisin B 1 and FB 2 produced by F. verticillioides was mainly reduced by Tri. harzianum , Tri. asperelloides , and Tri. asperellum to 59.4 and 0 µg/g, respectively. Fumonisin B 1 and FB 2 produced by F. proliferatum were mainly reduced by Tri. asperelloides and Tri. harzianum to 244.2 and 0 µg/g, respectively. This is the first study that reports on the efficacy of Tri. asperelloides against FB 1 , FB 2 , and OTA, P. janthinellum against AFB 1 , and Tra. cubensis against AFB 1 .

Background. In Mexico, corn is the most important crop, being an important input with food, economic, political, and social implications. However, intensive cultivation methods, based on chemical pesticides, monoculture and synthetic agrochemicals have caused a reduction in soil fertility and crop yields. An alternative, which can help restore soil fertility, increasing organic matter, moisture retention and the load of microorganisms, is mixed fertilizer. Stimulating, in addition, the defense systems of the plants and thus increasing the yield of the crops. Objective. To evaluate some fertilization schemes in Chalqueño maize plants through the measurement of some growth and yield variables. Methodology. A completely randomized block experimental design was established with three repetitions, where four fertilization schemes were evaluated (T1, control without fertilizer input; T2, chemical fertilizer; T3, organic fertilizer; and T4, chemical fertilizer + organic fertilizer) during the crop years 2019-2020. Results. The analyzes showed significant differences (p ≤ 0.05) between the evaluated treatments and years of cultivation. Being the T4 treatment, the one that obtained the best grain yield for the years 2019 and 2020, with values of 5.11 ± 0.05b t ha-1 and 6.57 ± 0.95a t ha-1, while the T1 treatment, recorded 1.59 ± 0.12f t ha-1 and 2.15 ± 0.38e t ha-1, respectively. Implications. With the information generated, it will be possible to implement the best fertilization scheme that provides the corn plants with all the necessary nutrients so that year after year they obtain the best grain yields. Conclusion. Through the results it was possible to demonstrate the negative effect of environmental factors (higher temperature and less rainfall), on the yield of the corn crop during the year 2019, with respect to the best yield result obtained for all the treatments during the year 2020 where a lower temperature and higher rainfall were recorded. Being equally evident the positive effect on the yield when plants were fertilized with the T4 treatment that provided to the corn crop with an adequate dose of moisture and macro and micronutrients.
