“…Crops heavily sprayed with fungicides might never show infections from some common foliar pathogens (Haq et al, 2020). However, leaf diseases are often taken seriously only if they result in a sudden outbreak or cause moderate to complete defoliation a few years in a row.…”

“…Moreover, climate change and the rise of pesticide resistance also reduce the effectiveness of synthetic chemicals. This has led many scientists to search for potent alternative strategies against plant diseases ( Ul Haq et al, 2020 ). The application of biological control methods is considered an effective alternative strategy ( Lazarovits et al, 2014 ).…”

Plant bacterial and fungal diseases cause significant agricultural losses and need to be controlled. Beneficial bacteria are promising candidates for controlling these diseases. In this study, Streptomyces sp. JCK-6131 exhibited broad-spectrum antagonistic activity against various phytopathogenic bacteria and fungi. In vitro assays showed that the fermentation filtrate of JCK-6131 inhibited the growth of bacteria and fungi with minimum concentration inhibitory (MIC) values of 0.31–10% and 0.31–1.25%, respectively. In the in vivo experiments, treatment with JCK-6131 effectively suppressed the development of apple fire blight, tomato bacterial wilt, and cucumber Fusarium wilt in a dose-dependent manner. RP-HPLC and ESI-MS/MS analyses indicated that JCK-6131 can produce several antimicrobial compounds, three of which were identified as streptothricin E acid, streptothricin D, and 12-carbamoyl streptothricin D. In addition, the disease control efficacy of the foliar application of JCK-6131 against tomato bacterial wilt was similar to that of the soil drench application, indicating that JCK-6131 could enhance defense resistance in plants. Molecular studies on tomato plants showed that JCK-6131 treatment induced the expression of the pathogenesis-related (PR) genes PR1, PR3, PR5, and PR12, suggesting the simultaneous activation of the salicylate (SA) and jasmonate (JA) signaling pathways. The transcription levels of PR genes increased earlier and were higher in treated plants than in untreated plants following Ralstonia solanacearum infection. These results indicate that Streptomyces sp. JCK-6131 can effectively control various plant bacterial and fungal diseases via two distinct mechanisms of antibiosis and induced resistance.

“…Currently, large‐scale crop production is highly dependent on efficacious fungicide applications because under favourable conditions the pathogen has greater ability to cause damage if no control measure is applied (Ul Haq et al., 2020). A meta‐analysis of fungicide efficacy field trials on Soya bean target spot from 2012 to 2016 in Brazil demonstrated that the most effective fungicides were the mixtures fluxapyroxad + pyraclostrobin and epoxiconazole + fluxapyroxad + pyraclostrobin.…”
