“…Many experiments conducted all over the world demonstrated parasitism of S. sclerotiorum sclerotia and reduction of apothecia density by Trichoderma isolates (Geraldine et al 2013). Most of these experiments were conducted under laboratory or greenhouse conditions (Matroudi et al 2009;Smolinska et al 2016).…”

“…Most of these experiments were conducted under laboratory or greenhouse conditions (Matroudi et al 2009;Smolinska et al 2016). However, the number of reports dealing with the antagonistic activity of Trichoderma in field conditions is rather limited Zeng et al 2012a;Geraldine et al 2013). Geraldine et al (2013) observed a reduction of S. sclerotiorum apothecia number and disease severity after application of T. asperellum at the dose of 2 x 10 12 spores ml -1 per plot in two years of field experiments with common bean.…”

Diseases caused by Sclerotinia sclerotiorum (Lib) de Bary are difficult to control and cause increasing losses of horticultural crops worldwide. Reasons of this phenomenon are various: (i) the specialization of crop production that causes the accumulation of the pathogen in the soil; (ii) the lack of a safe and efficient method of soil fumigation; (iii) the specific life cycle of S. sclerotiorum with survival structures (sclerotia), resistant to chemical and biological degradation. Sclerotinia diseases depend on many environmental factors which determine sclerotia survival and ascospores dissemination, because plants are mainly infected by air-borne ascospores from carpogenic germination of sclerotia. Due to the lack of effective synthetic agents for eradication of S. sclerortiorum from soil considerable interest has been focused on biological control, especially the selection of microorganisms with mycoparasitic activity towards S. sclerotiorum sclerotia, that can decrease their number in the soil. In this work we review reports on the use of different antagonistic fungi and bacteria in the control of S. sclerotiorum and discuss the suppressive effect of organic amendments against this soil-borne pathogen.

BACKGROUNDSclerotinia sclerotiorum is a devastating fungal pathogen that poses a threat to a variety of economically important crops. Owing to the lack of highly resistant cultivars and the prolonged survival of sclerotia, effective control of Sclerotinia diseases remains challenging. RNA interference (RNAi) agents targeting essential active transcripts of genes associated with the development and virulence of pathogens are a valuable and promising disease control method.RESULTSOur finding suggested that a flavin adenine dinucleotide (FAD)‐dependent monooxygenase gene SsMNO1 plays pivotal roles in the hyphal growth, sclerotial development, and virulence of S. sclerotiorum, rendering it a potential target for RNAi‐mediated management of S. sclerotiorum. The external application of double‐stranded RNA (dsRNA) targeting SsMNO1 inhibited sclerotial development in artificial media and plant tissues. Furthermore, dsRNA significantly reduced the hyphal virulence of S. sclerotiorum in host plants by interfering with SsMNO1 expression. The inhibitory activity persisted for over 1 week on the surface of Brassica napus. Artificial small interfering RNA (siRNA) targeting SsMNO1 also exhibited inhibitory effects. Transgenic Arabidopsis thaliana plants expressing SsMNO1 hairpin RNAi constructs showed increased resistance to S. sclerotiorum infection. Notably, the total RNA extracts from SsMNO1‐RNAi plants also reduced the hyphal virulence in Brassica napus.CONCLUSIONSTherefore, RNAi agents targeting SsMNO1 have dual effects on sclerotial development and hyphal virulence, rendering it an ideal target for controlling diseases caused by S. sclerotiorum. © 2024 Society of Chemical Industry.
