“…This result is similar to that reported by Cabrefiga et al (2023) where application of T. asperellum to the soil reduced between 30% to 40% leaf blotch, and fruit spot caused by Alternaria spp. was reduced between 50% and 80%.…”

“…The role of T. asperellum as antagonistic against different plant fungi pathogens such as A. solani (Ronnie-Gakegne and Martínez-Coca, 2018), Fusarium oxysporum (Hao et al, 2022, Rubio-Tinajero et al, 2022Sharma et al, 2022), Sclerotinia sclerotiorum, A. solani, Phytophthora sphave (Sharma et al, 2022), Puccinia striiformis (Esmail et al, 2022) have been demonstrated. Alternaria comprise a group of species causing several damages on different plants, including apple trees, to which they can induce leaf blotch and fruit spot (Cabrefiga et al, 2023).…”

“…Tamandegani et al (2020) reported that T. asperellum increased the production of peptaibol (trichotoxin) during in vitro confrontation with fungal plant pathogens such as Alternaria solani, Fusarium oxysporum, F. moniliforme, F. graminearum, F. culmorum, and Rhizoctonia solani. In this context, Cabrefiga et al (2023) applied T. asperellum in the soil of a commercial apple orchard to control Alternaria spp., resulting in 50% to 80% reduction of fruit spots and 30% to 40% decrease of leaf blotch.…”

Chihuahua state is the main apple producer in Mexico. The present study aimed to evaluate the effectiveness of Trichoderma asperellum as a plant growth regulator and antagonist against Alternaria sp. Three treatments were used: T1 = control, T2 = 200 mL of T. asperellum per tree; T3 = 100 mL of T. asperellum per tree. Agronomic variables were evaluated including number of leaves, shoots and flowers, disease incidence, and trunk thickness. Alternaria sp. was isolated from apple leaves at the experimental site in Guerrero County, Chihuahua, Mexico, and it was grown on solid PDA medium for morphological characterization. The molecular characterization was done by PCR using primers ITS1 and ITS4 producing products of 700 bp which were sequenced, submitted to GenBank (acc. no. OQ344593) and used for further phylogenetic analysis through Bayesian inference approach. Three clades were identified and the polytome topography recovered from clade 2 indicates a high genetic similarity with A. tenuissima (100% similarity according to BLAST). The analysis of T. asperellum as growth regulator only showed significant differences in trunk thickness and displayed higher values with T3 (p≤0.05). The presence of A. tenuissima was only observed in the control, which indicated the ability of Trichoderma to control the fungus. In this study T. asperellum was not an efficient plant growth regulator, but it was a good antagonist, and hence it can be recommended to control A. tenuissima. This is the first record of A. tenuissima in apple trees in Mexico. These results indicate that T. asperellum showed no benefit as plant growth regulator when applied to apple trees of the ‘Granny Smith’ variety.

Scaffold structures, new mechanisms of action, and targets present enormous challenges in the discovery of novel pesticides. The discovery of new scaffolds is the basis for the continuous development of modern agrochemicals. Identification of a good scaffold such as triazole, carbamate, methoxy acrylate, pyrazolamide, pyrido-pyrimidinone mesoionic, and bisamide often leads to the development of a new series of pesticides. In addition, pesticides with the same target, including the inhibitors of succinate dehydrogenase (SDH), oxysterol-binding-protein, and p-hydroxyphenyl pyruvate dioxygenase (HPPD), may have the same or similar scaffold structure. Recent years have witnessed significant progress in the discovery of new pesticides using natural products as scaffolds or bridges. In recent years, there have been increasing reports on the application of natural benzopyran compounds in the discovery of new pesticides, especially osthole and coumarin. A systematic and comprehensive review of benzopyran active compounds in the discovery of new agricultural chemicals is helpful to promote the discussion and development of benzopyran active compounds. Therefore, this work systematically reviewed the research and application of benzopyran derivatives in the discovery of agricultural chemicals, summarized the antiviral, herbicidal, antibacterial, fungicidal, insecticidal, nematicidal and acaricidal activities of benzopyran active compounds, and discussed the structural−activity relationship and mechanism of action. In addition, some active fragments were recommended to further optimize the chemical structure of benzopyran active compounds based on reference information.

“…Cabrefiga et al [ 8 ] described an integrated approach for the control of Alternaria spp., the causal agent of apple leaf blotch and fruit spot disease, which recently appearance in Spain, where it causes important losses. This disease is difficult to control and requires a lot of treatments during the season.…”
