“…The result of the experiment clearly indicates that five numbers of fungicidal sprays on the susceptible variety like Sonali, reduce the disease levels significantly. These findings are in agreement with those of Mahapatra and Das (2017), who reported the reduction in AUDPC values of Alternaria leaf blight in mustard with increased number of Iprodione sprays. Shukla et al (2014) suggested that two sprays of Carbendazim (0.1%) were sufficient to manage the disease severity.…”

Anthracnose of green gram caused by Colletotrichum truncatum (Schwein.) Andrus and W.D. Moore occurs severely in Indo- gangetic plains every year. Experiment was conducted for two consecutive years (2013 and 2014) to assess yield losses to develop yield loss models. The linear regression models were developed by two parameters i. e. percent yield loss and avoidable yield loss as dependant variable and area under disease progress curve (AUDPC) as independent variable. The two years pooled mean revealed that a drop of 0.3 to 0.33 qha-1 in pod yield and a drop of 0.16 to 0.20% in avoidable yield loss of pod yield due to every 1% increase in AUDPC. Three sprays of Propiconazole 25 EC (0.1%) at 10 days interval beginning from 20 days after sowing resulted in lowest anthracnose under moderate disease pressure and four sprays for high disease pressure resulted in highest pod yield of 5.17q/ha and 5.08q/ha respectively. Highest avoidable losses of pod yield and percent yield loss over potential yield due to anthracnose were 48.82% and 3.55% for three sprays and 49.74% and 1.77% for four sprays respectively. The result also showed that three sprays of fungicide (Propiconazole 25 EC @ 0.1%) resulted in minimizing the disease and maximizing the profit by high benefit cost ratio (B:C) ratio.

“…Sacc. and Alternaria brassicicola is one among the important diseases of Indian Mustard with severe losses up to 70% in Rapeseed (Brassica campestris) (Kolte 2002); (Kolte et al, 1987), which had reported from across the globe causing 10-70% yield losses in which 15 to 71% losses were reported from India (Kadian and Saharan, 1983;Ram and Chauhan, 1998) depending on the crop species, being high in Brassica rapa with 35-40% in Indian Mustard (Chattopadhyay, 2008). These fungal pathogens chase the crops in every stage of the crop growth ultimately resulting in huge losses in the quality of the produce.…”

Indian Mustard that is emerged as the core oilseed crop is cultivated in the northern regions of India during Rabi season. Alternaria blight is one of the most destructive pathogens for Indian Mustard resulting in huge losses in quality and quantity of the produce. A research study was taken up to control the alternaria blight in Indian Mustard with selected eco-friendly treatments by monitoring disease intensity and yield attributes. It is noted that T2 – Trichoderma viride has shown significant results on disease intensity and yield attributes, where disease intensity has significantly minimised in T2 may be due to the mycoparasitic nature and ability to generate volatile and non-volatile compounds against pathogen with great anti-microbial activity. The results showed that maximum plant height (56.10 cm), test weight (4.11 g) and seed yield (1.21 t/ha) of Indian Mustard with minimum disease intensity (40.21 %) were recorded in the treatment T2 and followed by T6 – neem leaf extract @15% that has shown significant results on Alternaria blight.

“…(Sinha et al, 1992;Meena et al, 2011;Biswas, 2013;Kumar et al, 2013). The role of environmental factors in disease development as well as suitable chemical measures for disease control have been previously studied by many workers (Jagana et al, 2013;Kumar et al, 2014;Mahapatra and Das, 2016;Mahapatra et al, 2018).…”

The field studies were conducted at the research farm, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India during rabi seasons of 2017–18 and 2018–19. The objective of the research was to establish a relationship between disease severity of Alternaria blight with epidemiological factors in Indian mustard under Integrated Nutrient Management. Severity of disease in the specified time intervals was measured under 10 different nutrient management treatments combinations. Results showed that the highest intensity of Alternaria blight was observed with a mean maximum temperature of 19.3 to 24.4°C, mean minimum temperature of 7.6 to 14.1°C, average temperature of 13.5 to 19.3°C and an average relative humidity of more than 70%. The nutrient management in different combinations resulted different disease severity on leaves and pods and with increase in the age of the plant, significant increase in disease severity was observed. Maximum increase in disease severity was observed on 95 days after sowing (DAS) (44.77%) followed by 80 DAS (38.99%) and 65 DAS (32.99%) irrespective of their different treatments. Minimum disease severity was observed (13.83%) when the plots were treated with Azotobacter @ 250 g kg-1 seed, Phosphobacteria @ 250 g kg-1 seed along with FYM @ 7.5 t ha-1. Empirical relationship was established between different weather factors and Alternaria blight under different nutrient management practices which will be useful to forecast the first appearance of the disease accurately.
