AC Gayed is a flue-cured tobacco (Nicotiana tabacum) cultivar bred at the Pest Management Research Centre of Agriculture and Agri-Food Canada. It is a a black root rot (Chalara elegans) resistant, backcross derivative of Delgold (ST205/PB19//*5 Delgold) (Pandeya and White 1984). The resistance gene originated from Nicotiana debneyi.

Disappearance of parathion from flue-cured tobacco
Archives of Environmental Contamination and Toxicology, 1974Replicated field experiments were conducted at three locations in North Carolina to study the disappearance of parathion from flue-cured tobacco. Immediately after application, parathion residues on green leaves, averaged over locations, were 51.0 and 78.8 ppm, respectively, for the 0.56 and 1.12 kg/ha rates. These residues dropped to 0.63 and 1.50 ppm

NEWDEL, A FLUE-CURED TOBACCO CULTIVAR
Canadian Journal of Plant Science, 1984Newdel was developed at the Agriculture Canada Research Station, Delhi, Ontario. It represents an improvement over Virginia 115 in several agronomic, physical, chemical and smoke characteristics. Newdel essentially exhibits all the desirable traits of Nordel with a significant improvement in yield.Key words: Tobacco, Nicotinia tabacum, Nicotina ...

Herbicide Performance in Flue-Cured Tobacco
Weed Science, 1970Weed control performance of several herbicides, their effects on tobacco(Nicotiana tabacumL.), and two methods of soil incorporation were studied in North Carolina in 1967 and 1968. Herbicides which gave acceptable weed control without injuring tobacco or lowering its quality were 4-(methylsulfonyl)-2,6-dinitro-N,Ndipropylaniline (nitralin),1,1,4 ...

Nitrogen Requirements for Flue‐Cured Tobacco
Agronomy Journal, 2006Fertilizer N excesses may have negative effects on both crop and water quality. To reduce the risk of N excesses it is essential to accurately define fertilizer N rates. The estimate of the most suitable N rate is complicated by the fact that a certain amount of the N taken up by the crop during the growth season is supplied by the soil.

INFLUENCE OF ETHEPHON ON FLUE-CURED TOBACCO
Canadian Journal of Plant Science, 1977Ethephon (2-chloroethylphosphonic acid) was applied to flue-cured tobacco plants subjected to variations in cultural regime and harvesting technique to determine its influence on maturation, yield and quality. The response to ethephon treatment was evident in ripe or nearly ripe leaves after 3 days.

Tobacco Budworm Control in Flue-Cured Tobacco, 1990
Insecticide and Acaricide Tests, 1991Abstract Flue-cure tobacco 'Var. NC NF37 was transplanted at the Coastal Plain Experiment Station, Tifton, Ga., on 26 Mar. Plots 4 rows wide (36 in apart) × 20 ft long were arranged in a randomized complete block design replicated 4 times. Treatments were separated by single untreated border rows with the center 2 rows of each plot being

Alkaloid Analysis in Flue-Cured Tobacco
1994Tobacco (Nicotiana tabacum L.) is the most widely grown commercial non-food plant, with world production at 2.4 million ha in 1991 (USDA-FAS 1991). It is a New World crop that has alternately been valued for its medicinal properties and condemned as being a health hazard. Although there are 64 Nicotiana species currently known (Sisson and Severson 1990)
