“…However, a higher dose of N makes the crop susceptible to disease. Soil application of K as basal has been found to check Alternaria blight disease in mustard (Khatun et al 2011). It has been reported that sulfur, zinc, and boron decrease the development of Alternaria blight and increase seed yield of mustard crop (Khatun et al 2010).…”

It has been reported that sulfur, zinc, and boron decrease the development of Alternaria blight and increase seed yield of mustard crop (Khatun et al 2010). Application of some micronutrient, namely, B at 1 g/L, Mo at 1 g/L, S at 2 g/L, and Zn at 2 g/L, in various combinations reduced Alternaria blight disease and increased yield of rapeseed-mustard (Mondal 2008).…”

AgriculturalSciences. He has more than 22 years of research experience in oilseed crop disease management and has significantly contributed in the areas of understanding the host-pathogen interactions, epi demiology, and integrated disease management in sunflower, safflower, sesame, peanut, and rape seed-mustard crops. He has published more than 70 peer-reviewed research papers and 4 books. Dr. Chattopadhyay has to his credit several academic awards and one patent. His significant research achievements include the development of Fusarium wilt-resistant genotypes in safflower, the iden tification of genotypes of Brassica juncea resistant to a mixture of isolates of Albugo candida, the development of a biocontrol agent formulation to reduce the use of fungicides in the management of major diseases of oilseeds (Brassica), and seed treatment (and foliar application) of aqueous bulb extract of Allium sativum for the management of major foliar diseases (Alternaria blight, white rust, powdery mildew, and Sclerotinia stem rot) of mustard.

An experiment was conducted to evaluate the effect of NPK against the management of Alternaria black spot disease, productivity and oil content of mustard during 2015-16 and 2016-17 in the rabi seasons in the Krishi Vigyan Kendra, Katni (MP) with three doses of nitrogen, potassium and constant phosphorus. In the year 2015-16, each increased dose of nitrogen, there was a significantly increase in percent disease incidence on leaf from 26.66% to 47.41% and zero level of nitrogen shown less disease incidence (33.44% to 35.39%).Minimum incidence of disease (19.33%) in the year 2015-16 was recorded in the treatment applied 120kg nitrogen and 60kg potash. Increased dose of potash from 60kg to 80kg/ha with 120kg nitrogen increased the disease incidence (19.33% to 29%). Overall disease incidence on leaf increased with increase the nitrogen dose from 120kg to 160kg/ha with 80kg/ha potash. Highest disease incidence (47.41) was recorded in treatment given160kg N and 40kg K. Same trend of disease incidence on leaf was found in the year 2016-17. The highest seed yield (20.66q/ha)was achieved in 120kg N 60kg K along with 40kg P (Constant) applied plot followed by 140kg N and 60kg K (17.96q/ha and 120kg N plus 40kg K in the year 2015-16.There were no differences in seed yield among the treatment 1, treatment 3,treatment 4and treatment 6. Minimum seed yield (10.33q/ha) was obtained in control plot. In the year 2016-17, maximum yield (18.91q/ha) was recorded in plants receiving the 120kg N and 60kg K which was significantly higher than all the treatment plots. There was increased in yield with increase in K level from 40kg to 60kg/ha. Oil content was significantly decrease when plant were raised under higher doses of N and K. Significantly more oil percent (40.13%) was recorded in treatment applied 120kg N and 60 kg K followed by 120kg N and 40kg K (39.35) in comparison to control plot. Same trend of the oil recovery was also recorded in the year 2016-17.

“…Mackenzie (1981) reported that higher doses of nitrogenous fertilizer decreased the disease of Alternaria blight of tomato. Higher dose of nitrogen (140 and 160 kg N/ha) increased the disease incidence of Alternaria leaf blight of mustard (Khatun et al, 2011). Saharan et al (1982) observed that the application of N fertilizer to tomato increased the incidence of Fusarium wilt of tomato plants.…”

“…Sharma and Kolte (1994) reported that under natural conditions based on the number and size of spots, percent leaf and pod infection, average disease index on leaf and pods and number of spots on stem, K-fertilized plants reduced 30-45 per cent severity of Alternaria blight over N, P and NP fertilized plants in Toria. Higher dose of K (90 kg/ha) decreased the incidence of Alternaria leaf blight (Khatun et al, 2011). Chung and Huang (1993) observed that application of KCl to soil increased the resistance of Chinese kale plants to black spot disease.…”

Oilseed Brassicas are contributing approximately 28 percent of the Indiaâ€™s total oilseed production. This crop is gaining wide acceptance among t he f a rme r s b e ca u s e of adaptability for both irrigated as well as rainfed areas and suitability for sole as well as mixed cropping. Besides, it offers higher return with low cost of production and low water requirement. The production and productivity of oilseed brassicas are comparatively lower as compared to the world average due to the biotic and abiotic constraints. Among the biotic constraints, alternaria blight disease caused by Alternaria spp. has been reported from all the continents of the world, causing up to 70% yield losses in India. This disease was found on leaves, stems and siliquae and dark spots on the leaves and siliquae reduce the photosynthetic capacity and induce immature ripening, which causes reduced amount of quality seed and oil content. The severity of this disease depends upon weather conditions, varieties, age of host plants and virulence of the pathogens. Efforts are being done throughout the world for the management of alternaria blight of rapeseed-mustard. This paper comprehensively reviews the research of alternaria blight of rapeseed-mustard with special reference to management strategies through conventional, non conventional and biotechnological approaches that leads to planning the future research. The present scenario demands the traditional and modern biotechnological techniques bringing together for integrated disease management according to the need and availability at farmers level for sustainable management of alternaria blight disease of oilseed brassicas.
