“…In addition to its ability in suppressing pathogen growth, T. harzianum is also a phosphate dissolving microorganism that can be used by plants, so the growth of plant height occurs in good progress as it has growth-promoting effect. This is in accordance with Setiadi (1989) that the presence of T. harzianum in the soil is in synergy with the phosphate dissolving bacteria (Mercl et al 2020;Ojaghian et al 2019).…”

Abstract. Martanto EA, Tanati AE, Baan S, Tata HR, Murdjoko A. 2020. Effectiveness of biological control of Trichoderma harzianum on soybean leaf rust disease and the production in West Papua Lowland, Indonesia. Biodiversitas 21: 1935-1939. This study aims to evaluate the application of Trichoderma harzianum in leaf rust disease on soybean and its production. The study was conducted for three months starting from May to July 2017, at Residential Unit 11th Sidey Subdistrict, Manokwari District, West Papua Province, Indonesia. This study was designed using Factorial Complete Randomized Design consisting of two treatment factors and repeated three times. There was no treatment of pathogen inoculation in the field. The tested varieties had a different response to plant height. Burangrang, Grobogan, Dena-1, Anjasmoro, and Detam-1 varieties were categorized as moderate resistant varieties. The Trichoderma harzianum application should be applied in the whole crops of soybean to control environmentally the leaf rust disease. Seeds weight per plot for Dena-1 variety was higher compared to other varieties. The combination of Detam-1 varieties with Trichoderma treatment 2 times resulted in increased production.

“…inhibited the production of aflatoxins from the fungal pathogen Aspergillus flavus , through the downregulation of several genes involved in aflatoxin biosynthesis (Yang et al ., 2019; Lyu et al ., Lyu2020). Exposure of Sclerotinia sclerotiorum to VOCs produced by Trichoderma species led to the upregulation of four glutathione S‐transferase genes, which are involved in the detoxification of antifungal secondary metabolites, which may contribute to the virulence of Sclerotinia sclerotiorum (Ojaghian et al ., 2019). Sphingolipid metabolic processes, vesicle formation and trafficking, and membrane localization were all disrupted upon exposure of Botrytis cinerea to the Streptomyces ‐derived VOC caryolan‐1‐ol (Cho et al ., 2017).…”

“…For example, inhibitory mVOCs produced by Streptomyces yanglinensis 3–10 against Aspergillus were tested to determine their effects on plant development and showed that VOCs did not inhibit peanut seedling germination, suggesting promise for use under field conditions (Lyu et al ., 2020). The modes of action of VOCs in the suppression of target pathogens (Dalilla et al ., 2015; Cho et al ., 2017; Tahir et al ., 2017a; Xie et al ., 2018; Yang et al ., 2019; Ojaghian et al ., 2019), enhanced disease resistance of plants (Ryu et al ., 2004; Lee et al ., 2012; Song and Ryu, 2013; Tahir et al ., 2017a; Tahir et al ., 2017b; Song et al ., 2019b; Tyagi et al ., 2020) and plant growth promotion (Ryu et al ., 2003; Garnica‐Vergara et al ., 2016; Lee et al ., 2019; Tyagi et al ., 2019) are receiving increasing attention, future research priority should focus on understanding the mode of action of biologically active VOCs on target plants and pathogens. Whilst investigation of the efficacy of VOCs under field conditions has demonstrated promise, a wider range of VOCs require testing at this scale.…”

Harnessing microbial volatiles to replace pesticides and fertilizers

Global agricultural systems are under increasing pressure to deliver sufficient, healthy food for a growing population. Seasonal inputs, including synthetic pesticides and fertilizers, are applied to crops to reduce losses by pathogens, and enhance crop biomass, although their production and application can also incur several economic and environmental penalties. New solutions are therefore urgently required to enhance crop yield whilst reducing dependence on these seasonal inputs. Volatile Organic Compounds (VOCs) produced by soil microorganisms may provide alternative, sustainable solutions, due to their ability to inhibit plant pathogens, induce plant resistance against pathogens and enhance plant growth promotion. This review will highlight recent advances in our understanding of the biological activities of microbial VOCs (mVOCs), providing perspectives on research required to develop them into viable alternatives to current unsustainable seasonal inputs. This can identify potential new avenues for mVOC research and stimulate discussion across the academic community and agri-business sector.

“…The disease causes a considerable yield loss in many potato‐growing regions of Hamedan province, Iran (Ojaghian, 2011). Due to considerable crop damage, lack of highly resistant cultivars and difficulty of managing sclerotinia diseases, a significant amount of research is currently being focused on this pathogen (Ni & Punja, 2020; Ojaghian et al., 2019a,b). S. sclerotiorum is a soil‐borne fungus that overwinters as long‐lasting sclerotia in soil.…”

The objective of this study was to evaluate the inhibitory effect of pimaricin against Sclerotinia sclerotiorum, the causal agent of potato white mould. Field trials in 2016 and 2017 were conducted in Bahar and Lalehjin, Hamedan, Iran. Pimaricin at the concentration of 200 mg/L was able to reduce the disease incidence during field trials. The concentration of 2.5 mg/L completely inhibited the radial growth and sclerogenesis of three tested isolates of S. sclerotiorum. In addition, pimaricin at the concentration of 2.5 mg/L reduced the carpogenic germination of sclerotia in isolates 1, 2 and 3 by 100%, 88.1% and 73.9%, respectively. Treatment with pimaricin at the concentration of 2 mg/L for 160 min enhanced relative conductivity of S. sclerotiorum mycelia up to 100%. The concentration of 2 mg/L increased the cell membrane permeability of mycelia more than the concentration of 1 mg/L over 160 min. Moreover, exposure to pimaricin at the concentration of 2 mg/L for 12 hr increased carbohydrate leakage of the pathogen mycelia up to 73%. Pimaricin at the concentration of 2 mg/L markedly increased the content of methane dicarboxylic aldehyde (MDA) over time, and the highest content of MDA was recorded as 5.9 µmol/kg FW after 20 hr. The percentage of catalase activity was reduced in the pathogen mycelia by 4.1 U g−1 min−1 after exposure to pimaricin at the concentration of 2 mg/L for 20 min.
