“…Contrary to our study, isolated fungicide active ingredients (not mixed with other active ingredients) and isolated treatments of T. harzianum in two consecutive harvests were shown to be more efficient at controlling the severity and incidence of WM and improving yield than treatments containing pure fungicides (fluazinam) in the 2009-2010 crop (Sumida et al, 2015).…”

“…When pyrisoxazole (rarely used in Brazil) was used to control 166 strains of Sclerotinia sclerotiorum, it provided excellent protection and reduced disease in oleaginous plants (Duan et al, 2018). The fungicides procymidone and fluazinam (commonly used in Brazil) combined with benzalkonium chloride were more efficient in controlling WM in soybeans (73.1 -71.6%, 2010 crop; 75.7 -77.6 %, 2011 crop) than isolated applications of T. harzianum (Sumida et al, 2015).…”

The aim of this work was to study the effect of fungicides and biological agents on the control of white mold (Sclerotinia sclerotiorum) in common beans (cv. Pérola). Nine treatments were applied in six blocks (54 experimental units) using a randomized block design (RBD). The treatments were: T1 (control); T2, Bacillus subtilis strain QST 713 (4 L / ha); T3, B. subtilis strain QST 713 (4L / ha); T4, B. subtilis strain QST 713 (2 L / h); T5, B. subtilis strain QST 713 trifloxystrobin + prothioconazole (4 L / ha, 0.5 L / ha); T6, B. subtilis strain QST 713 trifloxystrobin + prothioconazole (2 L / ha, 0.5 L / ha); T7, B. subtilis strain QST 713 trifloxystrobin + prothioconazole, fluazinam (2 L / ha, 0.5 L / ha, 1 L / ha); T8trifloxystrobin + prothioconazole, fluazinam (0.5 L / ha, 1L / ha); T9-Trichoderma harzianum, difenoconazole and azoxystrobin fluazinam + (1.5 L / ha, 0.5 L / ha, 1 L / ha). White mold (WM) incidence was evaluated at 39 days after planting (DAP), with subsequent evaluations at 39, 46, 53, 60, 67 and 74 DAP. Average yield from T5, T6, T7 and T8 was statistically higher than in the other treatments and consequently, treatments T7, T8 and T9 had the lowest mean area under disease progress curve values. The combined chemical and biological treatment was an effective white mold management strategy that increased yield and decreased disease incidence in common beans.

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 integrated management of SSR utilizes a combination of cultural, chemical, and biological control practices (Peltier et al 2012). Some practices may include, crop rotation using nonhost crops (Gracia-Garza et al 2002;Mueller et al 2002aMueller et al , 2002bRousseau et al 2007), practicing reduced tillage (Gracia-Garza et al 2002;Kurle et al 2001;Mueller et al 2002a, b), using resistant cultivars (Grau et al 1982;Hoffman et al 2002;Kurle et al 2001), modifying the soybean canopy through seeding rate and row spacing (Jaccoud-Filho et al 2016;Kurle et al 2001;Lee et al 2005), and applying inseason chemical control (Mueller et al 2004;Peltier et al 2012;Sumida et al 2015;Saharan and Mehta 2008) (Fig. 1).…”

Sclerotinia stem rot (SSR), caused by Sclerotinia sclerotiorum, is one of the most important diseases of soybean. Disease management is complicated by the long-term survival of sclerotia in the soil and the absence of resistance in elite, commercial cultivars. Furthermore, the lifecycle of S. sclerotiorum in soybean fields is highly dependent on weather conditions, leading to a highly sporadic occurrence of the disease over seasons and an aggregated distribution within fields. Management relies on a multi-pronged approach of combining partially resistant cultivars with cultural practices, such as altering row spacing and planting population, along with chemical control. These control measures are constrained by economic trade-offs, incomplete efficacy of chemicals, and a lack of understanding of application timing for fungicides. Newer tools have been developed to improve management, such as disease prediction models that can assist farmers in making decisions about fungicide application. This review aims to introduce the Sclerotinia pathosystem in soybean, while covering the complicated biology of S. sclerotiorum that leads to the need for integrated management by soybean farmers.
