PATHOGENS 13/03/20 Biological Control of Tomato Gray Mold Caused by Botrytis Cinerea with the Entomopathogenic Fungus Metarhizium Anisopliae. Gray mold disease caused by Botrytis cinerea is a devastating disease that leads to serious financial loss.
In this study, the entomopathogenic fungus Metarhizium anisopliae that acts against the gray mold pathogen B. cinerea was evaluated. M. anisopliae produced a significant inhibition zone in front of the B. cinerea colony in the dual culture test. In addition, volatile organic compounds generated by M. anisopliae were shown to have an inhibitory effect on B. cinerea mycelia growth and reduced 41% of gray mold severity of postharvest tomatoes. The 10% concentration of the culture filtrate of M. anisopliae inhibited 88.62% of colony radial growth as well as 63.85% of sclerotia germination and all conidia germination of B. cinerea. Furthermore, the culture filtrate of M. anisopliae retained its inhibitory effect against the radial growth of B. cinerea even after heating for 15 min at 100 °C. J. AGRIC. FROOD CHEM. 14/05/19 Melatonin Induces Disease Resistance to Botrytis cinerea in Tomato Fruit by Activating Jasmonic Acid Signaling Pathway. Melatonin acts as a crucial signaling molecule with multiple physiological functions in plant response to abiotic and biotic stresses.
However, the impact and regulatory mechanism of melatonin on attenuating tomato fruit fungal decay are unclear. In this study, we investigated the potential roles of melatonin in modulating fruit resistance to Botrytis cinerea and explored related physiological and molecular mechanisms. The results revealed that disease resistance was strongly enhanced by melatonin treatment, and 50 μM was confirmed as the best concentration. Melatonin treatment increased the activities of defense-related enzymes and decreased hydrogen peroxide (H2O2) content with enhanced antioxidant enzyme activities.
UNIVERSITY MISSOURI 04/09/20 Integrated pest management - Powdery Mildew vs. Gray Mold on Tomato. David Trinklein University of Missouri (573) 882-9631 Published: September 4, 2020 The incidence of fungal molds on greenhouse and high tunnel tomatoes has increased in recent years.
While crop rotation would help to mitigate the problem, the high dollar value of tomato makes this an unattractive option to most growers. Therefore, disease management practices are extremely important for a successful crop. Accurate pest identification is the foundation on which a good disease management program is built. FRONT. PLANT SCI. 01/03/19 Infection Strategies Deployed by Botrytis cinerea, Fusarium acuminatum, and Rhizopus stolonifer as a Function of Tomato Fruit Ripening Stage. Introduction Fungi are important plant pathogens that cause large economic losses due to their ability to inflict diseases such as rot, rust, and wilt in various plant organs both preharvest and postharvest (Dean et al., 2012; Nabi et al., 2017).
Biotrophic fungi feed on living cells and suppress the host immune system by secreting effector proteins (Oliver and Ipcho, 2004; Glazebrook, 2005). In contrast, necrotrophic fungi feed on dead host cells and cause necrosis by secreting toxins and cell wall-degrading enzymes (CWDEs), among other virulence factors (van Kan, 2006).
Due to their ability to feed on dead host tissue, necrotrophic fungi are also sometimes grouped into the less defined group of saprotrophic fungi, which includes many fungi that do not actively kill host cells (Dyakov, 2007).

APS - DEC 2016 - Occurrence of Fungicide Resistance in Botrytis cinerea from Greenhouse Tomato in Hubei Province, China. During the early summer of 2012 and 2013, samples of gray mold were collected from greenhouse tomato at eight locations in Hubei Province, and 221 isolates of Botrytis cinerea were obtained and evaluated for the sensitivity to fungicides carbendazim, diethofencarb, boscalid, fludioxonil, and cyprodinil.
Results showed that isolates with resistance to carbendazim and cyprodinil were widespread, whereas isolates with resistance to carbendazim and diethofencarb were found at only two locations. No isolates with resistance to boscalid or fludioxonil were detected. INRA PACA - 2012 - Rapport de stage : Caractérisation de populations de Botrytis cinerea prélevées sur laitues et tomates.

Introduction Beneficial microbe-plant associations are common in nature, and their benefits to plant health and their potential application in agriculture are under extensive scrutiny (Campos-Soriano and San Segundo, 2011; Smith and Smith, 2011). Among these associations, arbuscular mycorrhizal (AM) symbiosis is one of the most widespread mutualistic associations worldwide. AM symbioses are established between soil-borne fungi from the phylum Glomeromycota, known as arbuscular mycorrhizal fungi (AMF), and the roots of more than 80% of plant species. These fungi are ubiquitous obligate biotrophs that colonize plant roots to obtain plant carbohydrates for the formation, maintenance, and function of mycorrhizal structures and to complete their life cycle (Bago et al., 2000).
MIR has been associated with the metabolic and genetic rearrangement that occurs as a consequence of the AMF colonization of roots that affects plant primary and secondary metabolism (Rivero et al., 2015). Results.
