Title:yield losses in soybeans glycine-max cultivar clark caused by bacterial tan spot
Authors:Dunleavy, J.M.
Source:Plant Dis. 1984, 68(9):774-776
Abstract:In a preliminary field test, cupric hydroxide was effective as a protectant in the field against Corynebacterium flaccumfaciens, the cause of soybean bacterial tan spot, in uninoculated, susceptible 'Clark' soybeans. It failed, however, to eradicate the disease in inoculated plants. The disease spread in both inoculated and unsprayed rows. In other trials, seed yield losses to tan spot ranged from 0.0 to 18.8%. Mean yield losses of 12.5% in 1979, 0.0% in 1980, and 4.3% in 1981 were measured at 3 locations, and a mean yield loss of 7.7% was measured at 1 location in 1978
