    Integrated management of tobacco leaf eating caterpillar Spodoptera litura F. in India

    CHARI M.S.; RAO R.S.N.; SREEDHAR U.
    Central Tobacco Research Institute (CTRI), Rajahmundry (A.P.) India
    Tobacco leaf eating caterpillar (Spodoptera litura F.) is a serious pest in tobacco nurseries and field crop. The pest causes damage to an extent of 80-100% in the nurseries under favourable wet conditions and 10-15% in the field crop. This pest is a...

    Screening germplasm resistance of tobacco to Phytophthora parasitica f. nicotianae causing black shank disease

    REDDY T.S.N.; NAGARAJAN K.
    Central Tobacco Research Institute (CTRI), Rajahmundry (A.P.) India
    Black shank (Phytophthora parasitica f. nicotianae) is a serious fungal disease in most of the tobacco growing tracts in India. The predominant race of the fungus in Andhra Pradesh is race O. In order to identify resistant/tolerant donors to this...

    Quantitative changes in volatile and non-volatile carbonyls of Dixie Shade wrapper tobacco from harvesting to ageing

    SRIVASTAVA R.P.; CHAUDHARY N.
    Central Tobacco Research Institute (CTRI), Research Station, Pusa, Bihar, India.
    Quantitative changes in carbonyls of cigar wrapper tobacco (C.V. Dixie Shade) were studied during 50-days of air-curing, 90-days of fermentation and 1 year of ageing of leaf. Volatile, non-volatile and total carbonyls increased enormously during...

    Central Tobacco Research Institute, Rajahmundry, India; Gujarat Agricultural University, Anand Campus, Anand, India; NRCG, Junagadh, India
    The radioactive tracer studies on flue-cured tobacco during curing and ageing have firmly established that both amino acids and unsaturated fatty acid, C18.3, are responsible, at least partially, for the generation of carbonyl compounds-some of the...
