Study on the control of downy mildew of onion with several new fungicides

양파노균병에 대한 신살균제의 효과비교실험

This experiment was compared Bordeaux mixture, which used to as good fungicide up to date, with new 6 fungicides for control of powdery mildew on onion from 1963 to 1864 in Pusan. In resulting treated blocks was better effect than untreated block, and specially Difolatan and Dithane M 45 was best. Dithane M 22, Dithane Z 78 and Orthocide was moderate but Sankinon and Bordeaux mixture was lower effect than formers.

1, 본 시험은 2개년에 걸쳐(1963-1964) 부산에서 양파로균병방제를 위하여 신살균제 6종을 공시하여 종래에 사용하여 오던 석회보르도와 비교시험하였다. 2. 약제처리구는 무처리에 비하여 방제효과를 인정할 수 있었으며 특히 Difolatan과 Dithane M 45는 그 효과가 우수하였으며 Dithane M22, Dithane Z 78, Orthocide도 석회보르도보다 효과가 좋았으며 산키농은 석회보르도와 함께 전자에 비해 약간 효과가 떨어지는 것을 알 수 있었다.
