Alternaria blight is one of the most deadly diseases of oilseed Brassica. This recalcitrant disease causes up to 50% yield loss across the globe. The disease is mainly caused by Alternaria brassicae and Alternaria brassicicola. These pathogens lack sexual stages and survive as conidia or condiospores on the debris of previous crops and susceptible weeds. Developing resistant oilseed Brassica cultivars to this disease has become a prime concern for researchers over the years. In absence of resistant oilseed Brassica cultivar, identification and introgression of resistance related genes can be a potential source for Alternaria blight resistance. As resistance toward Alternaria blight is governed by polygenes, intercrossing between the tolerant genotypes and subsequent selection will be the most appropriate way to transfer the quantitative resistance. For that reason, future breeding goal should focus on screening of germplasms for selecting genotypes containing resistance genes and structural features that favors resistance, like thick epicuticular wax, biochemical components such as phenols, phytoalexins and lower soluble sugars, reducing sugars and soluble nitrogen. Selected genotypes should be brought under appropriate breeding programs for attaining Alternaria blight resistance.

The effect of Amistar in controlling Alternaria blight of mustard was investigated and the selected mustard variety Rai- 5 was used. Amistar @ 0.05% (1 spray), 0.05% (2 spray), 0.05% (3 spray), 0.1% (1 spray), 0.1% (2 spray) and 0.1% (3 spray) were sprayed at 14 days interval beginning from 40 days after sowing (DAS). Amistar resulted significant reduction of the disease Alternaria blight (Alternaria brassicae and Alternaria brassicicola) severity and increased seed yield. Out of the doses of Amistar used, 0.1% (3 spray) showed marked effect in reducing the disease over control in terms of reduction of % Alternaria blight incidence, % leaf infection and % leaf area diseased up to 90.72%, 90.42% and 98.17%, respectively as well as reduction of % siliqua infection and % area of siliqua diseased up to 96.17% and 98.80%, respectively and thus increased seed yield up to 56.47% over control.

Progression of Alternaria blight disease was measured on two susceptible Indian mustard varieties viz., RH 30 and RH 0749 sown at three different dates. The maximum increase in disease severity was recorded between first weeks of February and last week of February. During this period, the maximum and minimum temperature, relative humidity at morning and evening, average vapour pressure of morning and evening, maximum and bright sunshine hours and wind speed were higher, which resulted in congenial conditions for severe infection by the pathogen. The disease severity was positively correlated with maximum and minimum temperature, average vapour pressure, wind speed, sunshine hours and evaporation, while relative humidity and rainfall negatively correlated with Alternaria blight on both the varieties. A maximum value of area under disease progress curve was observed on cultivar RH 30 (651.1 cm2) as compared to RH 0749 (578.9 cm2), when crop was sown on 9th November.
