In the present study, sixteen advance lines/cultivars of Brssicanapus
and Brassica juncea were screened out against Alternaria blight of brassica
(Alternariabrassicae). Out of eight lines/cultivars of B.napus, no line was
found to immune against A.brassicae. Legend, Oscar, and Dgl were moderately
resistant under field conditions and Shiralee was highly susceptible toA.
blight. Similarly in B.juncea, no line was observed immune; Khanpurrya,
Ryaanmol, AUB 99 and SM 8300 were moderately resistant and B527-1 was highly
susceptible to A. blight. In this study, three different plant extracts
(Ginger, Garlic and Turmeric) with 0.1%, 0.2% and 0.3% concentrations were evaluated
against A. blight. The disease severity for all the plant extracts varied
significantly at three different concentrations. Among these plant extracts,
Turmeric (Curcuma longa) with 0.3% concentration gave significant result
regarding disease intensity (12.74%) over control (26.86%). Similarly, these
plant extracts with different concentrations were used to check their efficacy
on yield (kg/ha) parameter. Turmeric with 0.3% concentration gave the
satisfactory result to increase the yield (1545.33 kg/ha) as compare to
untreated control (1086 kg/ha). - See more at:
