Pesticides of chemical synthesis have mainly been used to control pests, diseases and adventitious plants up until now. However, it has been shown that some pesticides can remain in the soil for long periods of time, thus affecting the development of organisms in the rhizosphere as well as human health, which are two of the most noteworthy side effects. The aim of this research was to analyze the compatibility of autochthonous Trichoderma strains with different synthetic fungicides, acaricides, insecticides (including an entomopathogenic fungus) and herbicides. Sulfur encouraged the growth of all autochthonous strains assayed, and the combination Trichoderma-B. bassiana did not disturb their growth. So, the combination of the autochthonous Trichoderma strains with these organic pesticides will be a positive strategy to apply in the field to control pests and some diseases. Conventional pesticides modified the development of all autochthonous Trichoderma strains, demonstrating that not only do they affect weeds, fungus or pests but also rhizosphere microorganisms. In conclusion, conventional pesticides indiscriminately used to control pests, diseases and weeds could reduce the development of autochthonous Trichoderma strains, especially fungicides and herbicides.

“…are inherently resistant against some fungicides, allowing the combined application in a mixture. Such a combination of T. virens and thiophanate-methyl was found to be compatible and more effective than either treatment alone against Fusarium solani and Fusarium oxysporum in field trials of dry bean production [47]. The vegetative growth of the plants and yield was also significantly increased for the combination compared to single treatment.…”

Combining Biocontrol Agents with Chemical Fungicides for Integrated Plant Fungal Disease Control

et al. 2020

Feeding a rising population of currently 7.8 billion people globally requires efficient agriculture, which is preferably sustainable. Today, farmers are largely dependent on synthetic fungicides to avoid food losses caused by fungal diseases. However, the extensive use of these has resulted in the emergence of fungicide-resistant pathogens and concerns have been raised over the residual effects on the environment and human health. In this regard, biocontrol agents (BCAs) have been proposed as an alternative to standard fungicides but their disease management capacity is usually incomplete and heavily relies on uncontrollable environmental conditions. An integrated approach combining BCAs with fungicides, which is the focus of this review, is put forward as a way to reduce the fungicide doses to manage plant diseases and thereby their residue on harvested crops. In addition, such a strategy of combining antifungal treatments with different modes of action reduces the selection pressure on pathogens and thereby the chances of resistance development. However, to allow its large-scale implementation, further knowledge is needed, comprising timing, number and interval of repeated BCA applications and their compatibility with fungicides. The compatibility of BCAs with fungicides might differ when applied in a mixture or when used in alternation.

“…Once established that the survival rate of the beneficial microorganism is not heavily affected by the action of the targeted fungicide, this type of integrated approach is now widely used in many pathosystems [ 59 ]. Synergistic application of fungicides and fungicide-tolerant biocontrol agents was successfully used in the management of several fungal diseases, such as Botrytis gray mold of grapes [ 60 ], Fusarium wilt disease in dry bean [ 61 ], rosemary Rhizoctonia aerial blight [ 62 ], Fusarium crown and root rot in tomato [ 63 ], Botrytis blight in ornamental plants [ 64 ]. Even more sustainable integrated approaches could be introduced to completely replace fungicide sprays.…”

Piriformospora indica Primes Onion Response against Stemphylium Leaf Blight Disease

et al. 2021

The root-endophytic fungus Piriformospora indica (=Serendipita indica) has been revealed for its growth-promoting effects and its capacity to induce resistance in a broad spectrum of host plants. However, the bioefficacy of this fungus had not yet been tested against any pathogen affecting onion (Allium cepa). In this study, the biocontrol potency of P. indica against onion leaf blight, an impacting disease caused by the necrotrophic fungal pathogen Stemphylium vesicarium, was evaluated. First, it was proved that colonisation of onion roots by P. indica was beneficial for plant growth, as it increased leaf development and root biomass. Most relevantly, P. indica was also effective in reducing Stemphylium leaf blight (SLB) severity, as assessed under greenhouse conditions and confirmed in field trials in two consecutive years. These investigations could also provide some insight into the biochemical and molecular changes that treatment with P. indica induces in the main pathways associated with host defence response. It was possible to highlight the protective effect of P. indica colonisation against peroxidative damage, and its role in signalling oxidative stress, by assessing changes in malondialdehyde and H2O2 content. It was also showed that treatment with P. indica contributes to modulate the enzymatic activity of superoxide dismutase, catalase, phenylalanine ammonia-lyase and peroxidase, in the course of infection. qPCR-based expression analysis of defence-related genes AcLOX1, AcLOX2, AcPAL1, AcGST, AcCHI, AcWRKY1, and AcWRKY70 provided further indications on P. indica ability to induce onion systemic response. Based on the evidence gathered, this study aims to propose P. indica application as a sustainable tool for improving SLB control, which might not only enhance onion growth performance but also activate defence signalling mechanisms more effectively, involving different pathways.
