“…The maximum benefit cost ratio 1:12.60 was obtained with Garlic bulb extract @1.0 followed by Trichoderma harzianum @ 1.0 (1:6.0), Nativo @ 0.05% (1:4.01), Pseudomonas fluorescens @ 1.0 (1:3.79). Singh et al, (2016) have reported Garlic bulb extract @ 1.0 and Trichoderma harzianum @ 1.0 as most economic as compared to others which supports the present findings. The maximum cost benefit cost ratio (1:21.83) was also reported (Mahapatra and Das, 2016) only single application of Garlic bulb extract which is highly acceptable for eco-friendly management of Alternaria blight of mustard.…”

“…The variable results of fungicides and botanicals in reduction of disease severity of Alternaria blight may be attributed to the toxic principles present in the fungicides and botanicals. The efficacy of botanicals, biocontrol agent (Garlic bulb extract, Neem, Eucalyptus, Madar Dhatura and Trichoderma harzianum) and with fungicides in management of Altenaria blight of rapeseedmustard was also reported by other workers (Meena et al, 2008;Yadav, 2009;Patni et al, 2005, Singh et al, 2013Singh et al, 2016;Kumar et al, 2016).…”

Alternaria blight caused by Alternaria brassicae (Berk) Sacc. and A. brassicicola (Schw) Wiltshire is one of the most common and destructive disease of rapeseedmustard. The experiments were conducted under field condition to develop effective management strategies for this disease through evaluation of genotypes for resistance and application of fungicide, bio-agents and botanical. Out of 200 promising genotypes evaluated for resistance, none of the entry was found resistant, twenty two genotypes namely DLSC-1, DRMR-261, DRMR-270, GSC-101, GSL-1, NPC-20 and PHR-2, CNH-11-13, CNH-11-7, EC-552608, HNS-1001, PAB 04-10, PAB 05-16, PAB 05-19, PAB 09-05, PAB-2004-4, PAB-2005, PPBJ 5, PPBJ-2, PPBJ-3, PPBN 3 and PPBN-2 were moderately resistant and 63 genotypes moderately susceptible. Seed treatment with Apron @ 6g/Kg seed and spray of all fungicides, bio-agents and botanical extract, significantly reduced the blight severity in comparison to the untreated control (water spray). Of the fungicides, Nativo @ 0.05% was found most effective followed by Difenconazole @ 0.05%, Iprodione @ 0.2, Folicure @ 0.2, Difolatan@ 0.2, Mancozeb @ 0.2, Antracol @ 0.25, Pseudomonas fluorescens @ 1.0, Trichoderma harzianum @ 1.0 and Garlic bulb extract @ 1.0 which showed 8. 70%, 14.62%, 16.27%, 16.41%, 18.54%, 20.51%, 21.42%, 24.27%, 25.42%, and 26.83%, severity, respectively after third spray of each chemical, bio-agents and botanical extract. The disease severity of water spray control was 69.10%. Same tread was also recorded with per cent disease control. Maximum seed yield (kg/ha) and yield increase (%) of 1740.22, 37.90 was recorded with the treatment Nativo @ 0.05% followed by Difenconazole @ 0

“…The performance of Garlic aqueous extract had been studied by earlier workers viz. Singh et al,(2016), Mahapatra and Das (2013), Meena et al, 2008 andRajendra &Lalu, 2006 who also observed disease management effects of Garlic bulb extract in mustard crop for Alterneria blight. The findings of present investigations are in tune to their results.…”

Leaf blight of mustard is one of the major constraints for its successful cultivation and may be attributed to cause substantially high yield losses. Integrated Disease Management (IDM) practices, found suitable against Alternaria blight, developed and evaluated elsewhere, are here by tested and validated as IDM module with slight modifications as per local requirements. This is basically to demonstrate the benefit of good available technology to farmers as on farm trials (OFT). The comparative efficacy of four different treatments were incredibly convincing for the farmers. It was realized that all three modules were significantly superior over prevailing farmers’ practice. Overall, seed treatment with aqueous garlic bulb extract @ 5% (w/v) along with one spray of aqueous garlic bulb extract @5% (w/v) at 45 DAS followed by one foliar spray of Mancozeb-75% WP @ 2.5g/l at 75 DAS (T4) found most effective in reducing disease incidence consecutively for three years and average reduction in disease severity of 71.90%. Besides, reduction in disease severity significant increase in yield and yield attributing characters could be observed using this treatment. The average yield increase of 37.30% could be recorded with maximum B:C of 2.56. In this way, treatment improved production and other yield parameters without imposing any drastic input burden to farmers, as evidenced by cost and benefit estimates. Therefore, it can be concluded that T4 can be considered for improved sustainable package of practice for Alternaria blight management of Mustard

“…Among the more popular chemicals, spraying with difolatan (captafol); dithane-M 45, dithane-Z 78 and cuman L (dithiocarbamates); bavistin (carbendazim); panolil (guazatin); baycor (bittertanol); syllit (dodecyl guanidine acetate); daconil (chlorothalonil); wettable sulphur; dueter (fentin hydroxxide); fentin acetate; Topsin-M (thiophanate-methyl) and TPTH (triphenyl tin-hydroxide) @ 0.2-0.25% provide effective control of the disease and result in significant increase in crop yield (Chahal and Sekhon, 1980;Kaushik 1983;Singh and Bhowmik, 1985;Chahal, 1986b;Kolte 1987;Tripathi 1987;Dasgupta, 1991;Chattopadhyay and Bagchi, 1994;Mridula 1994;Godika 2001;Singh and Singh, 2005b;Khan , 2007b;Singh 2013a, b;Srivastava 2014;Singh .,2014b;Singh 2015c).…”

This review on Alternaria blight caused by singly or by mixed infection is one of the most widespread and destructive disease of oilseed brassicas in all the continents. These pathogens are necrotrophs. The disease appears as black spot but later on enlarge and develops into prominent round spots with concentric rings. Many spots coalesce to form large patches showing blight and cause defoliation in severe cases. The spots on the mid-ribs of the leaves are linear and sunken. Circular to linear lesions also develop on stem and pods, which elongate at later stages. Infected pods produce small, and shrivelled seeds. This disease causes substantial yield losses as a result of several factors including reduced photosynthetic potential, early defoliation, flower bud abortion, premature ripening, siliquae dehiscence, seed shrivelling and reduced seed size, impairs seed colour and reduced oil content. This paper reviews the research on the development of Alternaria blight, describes the pathogens of Alternaria blight on rapeseed-mustard, which includes geographical distribution, economic importance, symptoms, habitat and host range, pathogen taxonomy, survival, pathogenicity and disease development, epidemiology, host resistance, breeding for disease resistance, genotypic stock, and management.
