Abstract:Several insecticides were evaluated for control of 1st- and 2nd-brood adults of the tobacco flea beetle, Epitrix hirtipennis (Melsheimer), on cigar-wrapper tobacco. Beetle tolerance to DDT and endrin was indicated, while Zectran® (4-dimethylamino-3,5-xylyl methylcarbamate) gave best protection from injury. The 1st brood injured a larger number of harvestable leaves than the 2nd.
Phytotoxic treatments were Baygon® (carbamic acid, methyl-, o-isopropoxyphenyl ester), Du-Ter® (triphenyl tin hydroxide), parathion + carbaryl, and SD 8447 (phosphoric acid, 2-chloro-1- (2,4,5-trichlorophenyl) vinyl dimethyl ester). Applications of Banol® (3,4-xylenol, 6- chloro-methylcarbamate) or Bayer 44646 (4-dimethylamino-m-tolyl methylcarbamate) when followed with parathion caused an increase in phytotoxicity, which indicated incompatibility. A saprophytic fungus (Botrytiscinerea Persoon), propagating on a tobacco stem diluent, caused severe chlorosis and necrosis.
Thorny-amaranth, Amaranthus spinosus Linnaeus, and Florida-beggarweed, Meiobomia purpurea Vail, were discovered as 2 new hosts of the beetle.
