Summary: This study investigated the biocontrol ability of Trichoderma harzianum CGMCC20739 (Tha739) against apple bitter rot caused by Colletotrichum gloeosporioides. The results showed that Tha739 effectively inhibited the growth of C. gloeosporioides and reduced its conidia production. In vivo tests demonstrated that Tha739 treatment could control apple bitter rot and maintain the nutritional quality of the fruit. These findings highlight the potential of T. harzianum Tha739 as a biocontrol agent for harvested apples.

Summary: In the control of plant diseases, biocontrol using Trichoderma harzianum and related species has shown efficient and safe results. To improve its biocontrol abilities, production of antimicrobial compounds and substances that trigger plant immunity should be increased, as well as resistance to different environmental stressors. Genetic engineering of the gene regulatory system can play a role in modulating various biological processes related to biocontrol. With advancements in fungal genetic engineering, it is expected that T. harzianum strains with enhanced biocontrol activities will be developed to support sustainable agriculture.

Summary: Coffee wilt disease is a serious threat to small-scale farmers in Ethiopia, and there are currently no effective control measures available. This study developed and evaluated biofungicides derived from Trichoderma species against the causative agent of the disease. The results showed that T. asperellum AU131 and T. longibrachiatum AU158 have high biocontrol efficacy.

Summary: Trichoderma can improve plant resistance to fungal pathogens through various means, with the mixture of TroT7 and ThaT2 significantly inhibiting the growth of several common fungal pathogens. This mixed biofertilizer also promotes lateral root growth of apple trees and soil metabolic processes, increasing the availability of nutrients in soil.

Summary: The study evaluated the antagonistic efficacy of Trichoderma viride and Trichoderma harzianum strains against the major causative agents of stalk rot disease of maize, with Trichoderma viride showing higher antifungal activity. Mycoparasitic action of T. harzianum against fungal pathogens was detected, while no mycoparasitism was observed for T. viride against them.

Summary: This study investigated the genetic and physiological mechanisms of T. harzianum ITEM 3636 in antagonizing the phytopathogenic fungi F. solani as well as its biocontrol effect on peanut brown root rot. The results showed that T. harzianum ITEM 3636 exerts its antagonistic activity against F. solani through the synthesis of secondary metabolites and high enzymatic activity. Greenhouse assays demonstrated that the application of T. harzianum ITEM 3636 on peanut seeds effectively reduced the incidence and severity of peanut brown root rot.

Summary: The aim of this study was to optimize the production medium for Trichoderma harzianum K179 biocontrol agent, analyze its kinetics at a larger scale, and economically assess its production through simulation modeling. The results showed that with the optimal composition of the medium and specific operation conditions, the production time of T. harzianum K179 bioagent can be shortened from 96 to 36 hours. The economic analysis suggested that this project is economically viable with a 25-year project lifetime and an investment payback time of 7.58 years.

Summary: A new partitivirus, Trichoderma harzianum partitivirus 2 (ThPV2), was discovered in a Trichoderma harzianum strain collected in China. The virus infection enhances the growth and development of the fungus and shows similar effects in inhibiting several important fungal and oomycete pathogens. Additionally, the ThPV2-infected strain shows moderately but significantly improved biocontrol activity against a specific pathogen compared to a cured variant strain.

Summary: This study investigated the inhibitory potential of 14 Trichoderma strains isolated from Asarum rhizosphere against Sclerotinia asari. The activity of antioxidant enzymes and differential metabolites in S. asari treated with two Trichoderma strains were evaluated. Results showed that T. koningiopsis B30 and T. hamatum A26 had the highest inhibition rates and non-volatile metabolites from the B30 strain showed 100% inhibition of S. asari. The activity of antioxidant enzymes decreased while the MDA content increased after treatment with the two Trichoderma strains. Transcriptome analysis revealed differentially expressed genes involved in metabolic pathways contributing to the antifungal activity of Trichoderma. These findings suggested the potential of B30 and A26 as biocontrol agents against Sclerotinia disease of Asarum.

Summary: Serine proteases and serine protease homologs (SPs/SPHs) play important roles in various physiological processes in insects. In this study, a total of 112 SP and 88 SPH genes were identified in the genome of the yellow mealworm. These genes were classified into different groups based on their domain structure and showed stage-specific expression patterns. The findings provide a foundation for further understanding the functions of SPs/SPHs in T. molitor.
