First report of Cotton leafroll dwarf virus from upland cotton (Gossypium hirsutum) in Arkansas
Plant Disease 104 (10), 2742-2742
Abstract: During 2019, cotton plants grown in Arkansas, U.S. were surveyed for virus diseases. A range of symptoms was observed, which included shortened internodes in the terminal part of the canopy, leaf distortion, upward leaf cupping, reddish-brown aborted flower bracts, and reduced boll set in the eight fields sampled. Overall, a disease incidence of <1% was visually observed in individual fields. The presence of Cotton leafroll dwarf virus was demonstrated in 6 out of 26 samples, collected from symptomatic plants using PCR analysis and nucleotide sequencing.
