Effect of seed disinfectants for controlling the soybean anthracnose was investigated with percent of seedling infection to seed or soil and with inhibition zone on potato dextrose agar. The chemicals tested were as follows: Arasan, Orthocide, Phygon-XL, P.T.A.B. and Mercuron. In seed inoculation, all the chemicals used resulted in significantly less seedling infection than that obtained in control. In the case of soil infection, the result was similar to the above but percentages of the infection were lower than the seed inoculation. Percentages of seedling infection were not necessarily correlated to the inhibition zones on potato dextrose agar by the same chemicals.
