“…Fungal material and disease assessments: The A. solani EAb 1 isolate [4,36] was generously provided by Dr. Ahmet Akköprü, the Department of Plant Protection, Faculty of Agriculture, Van Yuzuncu Yıl University, Turkey. The pathogen was grown on potato dextrose agar (PDA) and tomato seedlings were sprayed with a conidial suspension of 5 × 10 5 conidia mL −1 (prepared in sterilized water) using a manual sprayer.…”

“…A. solani can penetrate plant tissues directly or infect through stomata or wounds; the initial symptoms may appear on leaves as black or brown necrotic lesions that enlarge and turn into concentric rings. The fungus also infects different parts of the plants, such as shoots, stems, and fruits [1,4]. The severity of the disease depends on many factors, such as environmental conditions and the susceptibility of the host.…”

Early blight (EB), caused by the necrotrophic pathogen Alternaria solani, is one of the most common and destructive diseases in the tomato (Solanum lycopersicum L.). The use of fungicides is a prominent tactic used to control EB; however, their undesirable effects on the environment and human health, as well as involvement in the development of resistant strains, have driven researchers to search for new alternatives. Plant defense elicitors are exogenous defense-triggering molecules that induce a plant’s defense system associated with extensive transcriptional- and metabolic reprogramming of the genome and do not cause direct toxicity to phytopathogens. Moreover, 2,6-dichloroisonicotinic acid (INA) was an early-identified and strong plant defense elicitor to various phytopathogens. Recently, the combination of chitosan oligomers and pectin-derived oligogalacturonides that can mimic the induction of plants by a pathogen or damaged-derived molecules (PAMP and DAMP) were characterized as defense elicitors, named FytoSol. In this study, the preventive roles of these two defense elicitors—FytoSol and INA—against EB disease and its molecular basis, were explored. According to the results, FytoSol significantly reduced disease severity by an average of 30% for almost one month with an AUDPC value of 399 compared to the control, which had an AUDPC value of 546. On the contrary, INA did not provide any protection against EB. Gene expression analyses of these two distinct plant defense elicitors indicated that the expression patterns of several SA-, JA-, or ET-pathway-related genes (Pti4, TPK1b, Pto kinase, TomloxD, PRB1-2, SABP2, WRKY33b, WRKY70, PR-5, and PR3) were induced by defense elicitors differently. FytoSol extensively upregulated gene expressions of PR3, downregulated the SA-related defense pathway, and provided remarkable protection against the necrotrophic pathogen Alternaria solani. On the contrary, INA mostly induced genes related to biotrophic and/or hemibiotrophic pathogen protection. Our results indicate that FytoSol is a promising plant defense elicitor against EB and the modes of action of the elicitors are important to characterize their effects against pathogens. Further research may extend the use of defense elicitors as alternatives to pesticides in agriculture.

“…Goh et al (2020) reported that the leaf area, stem diameter, and plant height were significantly increased 5 months after inoculation by C. rosea compared to the controls. It has also been reported that some biological control agents increase the growth parameters of plants infected with A. solani (Fritz et al, 2006;Chowdappa et al, 2013;Boyno et al, 2020;2022). Lahlali and Peng (2014) was also determined that C. rosea stimulates the growth of pathogen-infected plants and induced plant resistance…”

“…The disease severity indices were at high rates in As inoculated plants at different times (3rd, 4th, 5th, and 6th) (Figure 3a). Boyno et al (2022) showed that the disease severity index exceeded 50% and reached the highest level five weeks after inoculation by A. solani. All doses of C. rosea (20 g, 30 g, and 40 g) were observed to reduce disease severity indices compared to As treatment.…”

Using of biological control agents on different plant diseases, including A. solani and V. dahliae has been reported in several studies (Boyno et al, 2020;Benouzza et al, 2021;Poveda and Baptista, 2021), which indicated the great importance of this technique (Naik et al, 2020;Karthika et al, 2020;Boyno et al, 2022).…”

The effectiveness of Clonostachys rosea against Verticillium wilt (Verticillium dahliae) and early blight (Alternaria solani) diseases, as the two most important problems in tomato cultivation with significant economic losses, was determined. It was determined that C. rosea was effective on A. solani and V. dahliae and suppressed mycelial growth. Also, the C. rosea on wheat grains inoculated to plants at 20 g, 30 g, and 40 g concentrations before and after pathogens inoculation. Then, fungal discs (2 mm in diameter) from V. dahliae growing colonies were inoculated on the host plant root zone. A. solani was also inoculated (1x106 conidia ml-1) by spraying the foliar parts of the plants. Results showed that V. dahliae caused 76.0% disease severity in control plants, while the disease severity indices were 58.3%, 55.3%, and 25.3% at 20 g, 30 g, and 40 g C. rosea application, respectively. In A. solani x C. rosea treatments, the disease severities were determined as 96.6%, 63.3%, 43.6% and 46.6% in control, 20 g, 30 g, and 40 g application of C. rosea, respectively. The pathogen suppression rates by C. rosea at 30g application dose was 54.8% against A. solani and at 40 g application dose was 66.6% against V. dahliae. The effects of C. rosea on plant growth parameters were also determined. Results showed that C. rosea had a positive effect on the morphological parameters in tomato plants.
