2009 Dark Tobacco Variety Guide *F or A refers to use as fire-cured or air-cured variety. F/A indicates either use, with predominant use given first. Relative yield and quality scores given on a 0-10 scale, with 10 being best for the predominant use. Dash (-) means that resistance level is unknown or not rated at present.

Current Dark Tobacco Research • Experimental pesticide screening trials: • Insecticides: • Coragen (rynaxypyr, DuPont) • Residual worm control • Foliar and setter water applications • Registration expected by 2010 • Rimon (novaluron, Chemtura) • Insect growth regulator, worm control • Brigadier (prepack mixture of Capture/Admire, FMC) • Worm and aphid control, foliar and setter water • Generic formulations of Admire (imidicloprid) • Alias 4F
Current Dark Tobacco Research • Experimental pesticide screening trials: • Fungicides: • Revus (mandipropamid, Syngenta) • Blue mold control in burley • Herbicides: • Spartan Charge (Spartan + Aim, FMC) • Performance in strip-till tobacco • Spartan + Command prepackaged mixtures (1 jug) • Re-evaluation of old Command Pro product
Current Dark Tobacco Research • Dark Fire-Curing: • Influence of microbial growth from dirt on harvested tobacco on TSNA development • Influence of wet tobacco at harvest on TSNA development • Alternative fire-curing methods and fuel sources
