“…Similarly, Huang et al (2006) found a reduction of between 65 and 87 % in production of apothecia by S. sclerotiorum sclerotia in bean fields when treated with Perlka ® at a rate of 60 g/m 2 .…”

“…The method was developed in previous work examining germination of S. sclerotiorum sclerotia and results in reliable production of apothecia (Clarkson et al 2007). Soil treatments of two products previously reported to have activity against S. sclerotiorum sclerotia, the fertiliser Perlka ® (calcium cyanamide) (Huang et al 2006) and the biological control Contans WG (a formulation of the mycoparasite Coniothyrium minitans) (Jones et al 2014), as well as the biofumigant product Biofence (mustard meal pellets) were also tested. B. napus 'Temple', a commercially grown winter oilseed rape cultivar, was used as a low GSL 'control' treatment to compare with the six biofumigant plants.…”

“…In addition, there is a general desire to reduce such fungicide inputs, and hence approaches to reduce the viability of S. sclerotiorum sclerotia are required. Various non-organic soil amendments have been shown to inhibit sclerotial germination, such as potassium bicarbonate (Ordonez-Valencia et al 2009) and calcium cyanamide (Perlka ® ) (Huang et al 2006). Other control approaches aimed at reducing the number of sclerotia in soil include crop rotation, soil solarisation and application of the biological control agent Coniothyrium minitans (Jones et al 2014;Mueller et al 2002;Swaminathan et al 1999).…”

AimsSclerotia of Sclerotinia sclerotiorum survive in soil and germinate to produce apothecia which release airborne ascospores. Current control methods rely predominantly on the use of fungicides to kill ascospores. The aim of this research was to identify potential biofumigation treatments which suppress sclerotial germination, providing a potential alternative and long-term approach to disease management. MethodsMicrocosm and in vitro experiments were conducted using dried and milled plant material from six different biofumigant crop plants to determine effects on carpogenic germination of sclerotia and mycelial growth of S. sclerotiorum. ResultsAll biofumigant plants significantly reduced germination of S. sclerotiorum sclerotia in the microcosm experiments, but were less effective against larger sclerotia. In vitro experiments showed a direct effect of biofumigant volatiles on both the mycelial growth of S. sclerotiorum, and carpogenic germination of sclerotia, where the most effective treatment was B. juncea 'Vittasso'.Conclusions It was clear from this study that biofumigant crop plants have potential as part of an integrated disease management system for control of S. sclerotiorum. The microcosm experiments described here provide a straightforward and reliable screening method for evaluating different biofumigants for activity.

“…Additionally, chemical amendment of soil has also been shown to be effective at reducing carpogenic germination of sclerotia. Namely, the commercially available fertilizer Perlka (calcium cyanamide) was shown to significantly reduce the number of apothecia in four field trials by up to 87% (Huang et al, 2006).…”

The control of sclerotinia stem rot on oilseed rape (Brassica napus): current practices and future opportunities

2016

View full text Add to dashboard Cite

Sclerotinia stem rot (SSR) caused by the phytopathogenic fungus Sclerotinia sclerotiorum is a major disease of oilseed rape (Brassica napus). During infection, large, white/grey lesions form on the stems of the host plant, perturbing seed development and decreasing yield. Due to its ability to produce long‐term storage structures called sclerotia, S. sclerotiorum inoculum can persist for long periods in the soil. Current SSR control relies heavily on cultural practices and fungicide treatments. Cultural control practices aim to reduce the number of sclerotia in the soil or create conditions that are unfavourable for disease development. These methods of control are under increased pressure in some regions, as rotations tighten and inoculum levels increase. Despite their ability to efficiently kill S. sclerotiorum, preventative fungicides remain an expensive gamble for SSR control, as their effectiveness is highly dependent on the ability to predict the establishment of microscopic infections in the crop. Failure to correctly time fungicide applications can result in a substantial cost to the grower. This review describes the scientific literature pertaining to current SSR control practices. Furthermore, it details recent advances in alternative SSR control methods including the generation of resistant varieties through genetic modification and traditional breeding, and biocontrol. The review concludes with a future directive for SSR control on oilseed rape.

“…The fungus has a large host range of more than 400 species and a worldwide distribution including numerous important crops and weeds 1, 2. The pathogen can cause serious losses of yield and quality for a number of important field and vegetable crops in Turkey3 and many other countries 4–6 . S. sclerotiorum may survive for a long period in the absence of plants owing to its specialised resistant structures, called sclerotia, which remain viable for up to 8 years in the soil 2, 7.…”
