Trichoderma: Dual Roles in Biocontrol and Plant Growth Promotion
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThis manuscript demonstrates how basic research can be applied to practical insights and policy implications within the scope of soil microbiology, plant sciences, and sustainable agriculture-oriented journals. This article, therefore, has great value because it can elucidate knowledge on molecular mechanisms of Trichoderma that could be exploited to develop improved biocontrol agents. The terms have been applied appropriately towards an intended audience.
The Figures and tables have been referenced and described. However, their quality in the final formatted version needs to be checked. References are quite adequate, up-to-date, relevant, and essential, both from foundational and recent works of literature. The authors critically discuss the benefits and limitations of Trichoderma use, including strain selection, compatibility with other biocontrol agents, and potential risks. The article is ready for publication, with only a few minor editorial changes recommended. It adds significant value to the field of sustainable agriculture and microbial biotechnology.
Finally, I recommend several improvements for the final document: verifying the quality of all figures and tables, enhancing the clarity of descriptions, and considering the compilation of a table or figure to summarize the mechanisms of action and applications of Trichoderma.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe work is interesting and contains basic information about the Trichoderma genus. However, you should explore each topic in greater depth and provide more specific details. For instance, regarding crop protection, you should mention the specific phytopathogens it can control because most studies focus on biocontrol in laboratories, not fieldwork. I would also like to see more detail on species linked to antibiosis and mycoparasitism in important crops around the world.
Cite more field studies on the diversity of species linked to biological control.
The section on agricultural applications does not clearly explain how the genus is linked to sustainable agriculture. Elaborate on this and mention the need for its use in organic production systems. This information should also be included in the introduction, where you should update the identified species for 2025 and mention the roles of Trichoderma discussed here.
there is no clear link between the title and the body of the manuscript. I suggest changing it. dual role in biological control and plant growth promotion (do not include the word “sustainable,” as this term is more complex and suggests a complementary section).

Thank you for your specific recommendation to incorporate more field studies on the diversity of Trichoderma species involved in biological control. We agree that highlighting a broader range of species and empirical field evidence will enrich the manuscript’s discussion, providing readers with a more robust understanding of Trichoderma’s practical applications across different agricultural contexts.
In response, we have expanded Section 5 (Agricultural Applications of Trichoderma) by adding citations to key field studies that demonstrate the diversity of Trichoderma species and their efficacy in real-world settings. This addition will strengthen the evidence base of the review, making it more comprehensive and actionable for researchers and practitioners. We appreciate your guidance in refining this aspect of the manuscript.
The section on agricultural applications does not clearly explain how the genus is linked to sustainable agriculture. Elaborate on this and mention the need for its use in organic production systems. This information should also be included in the introduction, where you should update the identified species for 2025 and mention the roles of Trichoderma discussed here.
RESPONSE:
Thank you for your insightful feedback regarding the linkage between Trichoderma and sustainable agriculture, as well as the suggestions for enhancements in the Agricultural Applications section and the Introduction. We agree that clarifying these connections will strengthen the manuscript’s narrative and emphasize Trichoderma’s relevance to eco-friendly farming practices, including organic systems.
In response to your comments, we implemented the following revisions:
Elaboration in the Agricultural Applications Section (Section 5): We expanded this section to more explicitly explain Trichoderma’s links to sustainable agriculture. This includes a dedicated paragraph discussing how Trichoderma contributes to sustainability by reducing reliance on chemical pesticides and fertilizers through its roles in biocontrol, soil health improvement, nutrient cycling, and enhanced crop resilience.
Incorporation into the Introduction: To provide early context, we integrated this information into the Introduction. This includes an updated estimate of identified Trichoderma species as of 2025, based on the latest taxonomic advancements. We also briefly outlined the key roles of Trichoderma discussed in the review—such as biocontrol against phytopathogens, plant growth promotion, stress tolerance enhancement, and ecological adaptations—to set the stage for the manuscript’s focus on its sustainable agriculture applications.
These changes are supported by additional references to ensure currency and evidence-based discussion, enhancing the manuscript’s overall coherence and impact. We believe these revisions will better articulate Trichoderma’s pivotal role in advancing sustainable and organic agriculture. Thank you again for your valuable input.

RESPONSE:
Thank you for your careful review and for pointing out the potential misalignment between the manuscript’s title and its content. We appreciate your suggestion to refine the title for better precision and to avoid implying an overly broad or separate focus on “sustainable” aspects, which could indeed complicate the scope given the term’s multifaceted implications.
In response, we revised the title to more directly reflect the core themes of the review—Trichoderma’s dual roles in biocontrol and plant growth promotion—while ensuring it ties closely to the body of the manuscript. The proposed new title is: “Trichoderma: Dual Roles in Biological Control and Plant Growth Promotion”.
This adjustment removes “Sustainable Agriculture” to align with your recommendation, uses “Biological Control” for consistency with standard terminology in the field (as suggested), and maintains a concise focus on the primary mechanisms discussed throughout the text. We believe this change enhances the title’s clarity and relevance, better guiding readers to the manuscript’s emphasis on Trichoderma’s mechanistic and applicative roles.

34: does all trichoderma non pathogenic?
RESPONSE:
Thank you for your query regarding the pathogenicity of Trichoderma species. We appreciate you raising this important point, as it highlights the need for precision in discussing the genus’s ecological roles.
To address your question: No, not all Trichoderma species are non-pathogenic. While the vast majority of Trichoderma species are saprophytic, beneficial to plants (e.g., through biocontrol and growth promotion), or harmless in agricultural contexts, a small subset can act as opportunistic pathogens. For instance:
Some species, such as Trichoderma longibrachiatum and T. citrinoviride, have been associated with infections in immunocompromised humans.
In rare cases, certain strains may exhibit weak pathogenicity toward plants under specific conditions, such as in wounded tissues or stressed environments, though this is uncommon and typically overshadowed by their beneficial traits.
Overall, pathogenicity is not a defining characteristic of the genus, and most species are considered non-pathogenic to plants and humans under normal circumstances.
To ensure clarity and accuracy, we revised line 34 and the surrounding text in the Introduction to explicitly note this nuance. We amended the sentence to: “While the majority of Trichoderma species are non-pathogenic saprophytes or beneficial symbionts in soil and plant ecosystems, a few can act as opportunistic pathogens in specific contexts, such as in immunocompromised hosts or under rare environmental conditions.”
We believe this adjustment will strengthen the manuscript by providing a more balanced and evidence-based portrayal of the genus. Thank you again for your valuable input.
