Effect of Bacterial Pustule and Frogeye Leafspot on Yield of Clark Soybean¹

The effect of bacterial pustule (Xanthomonas phaseoli var. sojensis (Hedges) Starr and Burkh.) and frogeye leafspot (Cercospora sojina Hara) diseases on the seed yield of ‘Clark’ soybeans (Glycine max (L) Merrill) was studied with artificial inoculation at Lafayette, Ind., from 1966 to 1968. Good initial bacterial pustule infection resulted in only mild disease and no significant differences in yield between inoculated and noninoculated plots. Frogeye infection was. severe in 2 of the 3 years and the diseased plots were 17 and 21% lower in yield. We concluded that bacterial pustule resistance is nonessential in the area because of failure of the disease to develop sufficiently to affect yield even with good initial infection. Resistance to frogeye leafspot is desirable to prevent reestablishment of a potentially destructive disease.
