“…Concerning the total fresh mass and total dry mass, all plants grown in soil treated with Trichoderma, do not differed from each other, it is evident that the commercial strains of Trichoderma were essential to obtain the TFM and BIO superior to the control. An explanation for this fact could rely on the study carried out by Oliveira et al (2018), where wheat plants inoculated with different Trichoderma strains, presented higher values of total fresh mass and total dry mass when compared to the control. This is, it presented greater roost system development and as consequence, increase in the fresh mass in several parts of the plant.…”

The growth of plants by the use of Trichoderma occurs through distinct mechanisms, among which it can highlight the synthesis of phytohormones and auxins analogues. The objective of this work was to evaluate Trichoderma spp. commercial strains in the promoting seedlings growth and in the productivity of parsley plants. In laboratory assay, seeds of parsley cv. ‘Graúda Portuguesa’ were treated with 2 mL of Trichoderma suspension (2.5 × 108 ml-1 conidia per 100 g of seeds) submitted to growth test until 28 days after sowing (DAS). For the greenhouse experiment, parsley seedlings were transplanted into 3.0 L pots containing soil, which was previously treated with 5 mL Trichoderma suspension, totaling 1.5 × 108 conidia per pot. In both, a control without Trichoderma application was included, being arranged in a completely randomized design (CRD). The evaluations were: percentage of germination (PG), root length (RL), shoot length (SL), total length (TL = RL + SL), fresh root mass (FRM), fresh shoot mass (FSM), total fresh mass (TFM = FRM + FSM), root dry mass (RDM), shoot dry mass (SDM), total dry mass (BIO = RDM + SDM), root mass ratio (RMR = RDM/BIO), shoot mass ratio (SMR = SDM/BIO), aerial part/root system retio (AP/RS = SDM/RDM) and productivity at 110 DAS. Althougth no diferences was observed among the Trichoderma treatments and the control about yield, Trichoderma spp. strains provided better TFM (18.98 to 22.92 mg), BIO (3.37 to 4.31 mg) and root system superior to the control (14.20 and 2.44 mg, respectively) under greenhouse conditions. T. harzianum ESALQ1306 was the better strain in laboratory assyas, suggsting this isolate for applied in the seeds when it aims the promotion of initial growth.

“…It effectively antagonizes soil pathogens (Wilson et al, 2008;Percival et al, 2011;Roberti et al, 2015;Fatouros et al, 2018) and can trigger ISR against diverse above-and belowground attackers (Tucci et al, 2011;Vitti et al, 2016;Coppola et al, 2017Coppola et al, , 2019Debode et al, 2018;Pocurull et al, 2020;Alınç et al, 2021). Besides promoting plant growth, T. harzianum ESALQ1306 has been shown to highly reduce Sclerotinia sclerotiorum disease severity through parasitism and to induce ISR against spider mites (Geraldine et al, 2013;De Oliveira et al, 2018;Barroso et al, 2019;Canassa et al, 2020). In contrast, R. irregularis is not a direct antagonist of plant pathogens, but is able to induce ISR against root and foliar pathogens (Martínez-Medina et al, 2011;Sanchez-Bel et al, 2016;Bidellaoui et al, 2019;Campo et al, 2020;Sanmartín et al, 2020).…”

Microbial Consortia for Effective Biocontrol of Root and Foliar Diseases in Tomato

et al. 2021

The use of beneficial microorganisms for the biological control of plant diseases and pests has emerged as a viable alternative to chemical pesticides in agriculture. Traditionally, microbe-based biocontrol strategies for crop protection relied on the application of single microorganisms. However, the design of microbial consortia for improving the reliability of current biological control practices is now a major trend in biotechnology, and it is already being exploited commercially in the context of sustainable agriculture. In the present study, exploiting the microbial library of the biocontrol company Koppert Biological Systems, we designed microbial consortia composed of carefully selected, well-characterized beneficial bacteria and fungi displaying diverse biocontrol modes of action. We compared their ability to control shoot and root pathogens when applied separately or in combination as microbial consortia, and across different application strategies that imply direct microbial antagonism or induced systemic plant resistance. We hypothesized that consortia will be more versatile than the single strains, displaying an extended functionality, as they will be able to control a wider range of plant diseases through diverse mechanisms and application methods. Our results confirmed our hypothesis, revealing that while different individual microorganisms were the most effective in controlling the root pathogen Fusarium oxysporum or the foliar pathogen Botrytis cinerea in tomato, the consortia showed an extended functionality, effectively controlling both pathogens under any of the application schemes, always reaching the same protection levels as the best performing single strains. Our findings illustrate the potential of microbial consortia, composed of carefully selected and compatible beneficial microorganisms, including bacteria and fungi, for the development of stable and versatile biological control products for plant protection against a wider range of diseases.

“…Therefore, the differences in germination promoting effects could be attributed to the specific association released between individual wheat cultivar and particular Trichoderma strain. Similarly, four various Trichoderma strains applied in wheat BRS 264 displayed different promoting potential ranging from 3% to 8%, while T. harzianum ESALQ 1306 provided the best results regarding germination and seedling performances under greenhouse conditions [ 48 ]. Trichoderma may improve germination by increasing the synthesis of endogenous plant growth regulators by up-regulation of genes for their synthesis and by down-regulation of genes included in their catabolism [ 49 ].…”

Seed treatments with zinc, boron, biostimulant Coveron and MIX (zinc + boron + Coveron) were applied to three lettuce and three celeriac cultivars. Seeds of three wheat cultivars were treated under laboratory conditions with Trichoderma harzianum and eight Bacillus spp. Seed germination, seedling growth, and the presence of the following pathogens were determined: Fusarium sp., Alternaria sp., Penicillium sp., and Mucor sp. The Coveron treatment was the most effective on lettuce seeds tested in the germination cabinet. Seed germination was higher by 4% than in the control. Alternatively, germination of seeds treated with boron in the greenhouse was higher by 12% than in the control. The Coveron treatment had the highest effect on the shoot length, which was greater by 0.7 and 2.1 cm in the germination cabinet and the greenhouse, respectively. This treatment was also the most effective on the root length. Zn, B, and MIX treatments increased celeriac seed germination by 14% in the germination cabinet. The Zn treatment was the most efficient on seeds tested in the greenhouse. The germination was higher by 15%. A significant cultivar × treatment interaction was determined in both observed species under both conditions. The maximum effect on wheat seed germination (8%) was achieved with the T. harzianum treatment in the Salazar cultivar. A significant interdependence (p ≤ 0.01 to p ≤ 0.001) was established between seed germination and the seedling growth. The interrelationship between seed germination and pathogens of all cultivars was negative.
