  • This study was carried out to select fungicides which are effective for the control of anthracnose disease of Carthamus tintorious L. caused by Cottetotrichum acutatum. Eive chemicals, i.e., thiophanate-methyl$.$triflumizole, iminoctadinetris$.$thiram, metiram, bitertanol$.$propineb, metalaxyl$.$dithianon were treated to Cheongiu native variety for the test of control effect. The results obtained were summarized as the follows; No. of harvested plants per ㎡ was most in iminoctadinetris$.$thiram and its value showed 21.2 compared with 16.8 in control. Iminoctadinetris$.$thiram and metiram were most effective to control the disease and their contyol values were 57.2%, and 49.4%, respectively. Chemical injury of five chemicals was not occurred at the double-diluted solution treatment. Seed yield was 47∼48% higher in iminoctadinetris$.$thiram and metiram than 75 kg/10 a in control.
