1) 본시험은 1962년과 1963년에 감자 겹둥근 무되병에 대한 살균제 7종을 공시한 효과비교시험이다. 2) 본병을 방제학 위하여 Alternaria solani를 접종한 후 6월 초순부터 1주일간격으로 4회 살포함으로서 방제효과가 우수하였다. 약제살포구는 무살포구에 대하여 유의성이 있었고 특히 Dithane M45, Difolatan, Dithane M22는 효과가 좋았으며 세 약제간에는 유성이 없었다. 그 다음으로 볼드액살포로서도 상당히 효과가 양호하였다.

1. The trials were planned to test seven different fungicides for the control of Early blight of potato during the period of 1962 and 1963. 2. All of fungicides tested in the trials were considerably effective to control the disease, as the result of 4 applications which was done in one week intervals from early of June in 1963. All treatments were effective enough to make significant differences from the untreated. Especially, Dithyane M45, Difolatan and Dithane M22 showed satisfactory control even though no significant differences were obtained among them. Besides the three treatments, Bordeaux Mixture were relatively effective.
