In 1983, 1984 and 1985 the following eleven chemicals were used against tobacco blue mold in the field : 1. Ridomil 25 W.P.; 2. Ridomil MZ 63.5 W.P.; 3. Ortho 9955; 4. Galben-Z 8-65; 5. Galben-M 17-54; 6. Galben-M 8-65; 7. Vinicur EC; 8. Vinicur M-SC; 9. Sandofan M; 10. Sandofan M8; 11. Alper W.P. From the above chemicals : Ridomil 25 W.P.; Ridomil MZ 63.5 W.P. and Vinicur EC, in all rates and modes of application used, gave excellent results. Galben-M 17-54 250 g/hl and 300 g/hl, Galben-M 8-65 300 g/hl (spray every 10 days) and 400 g/hl (spray every 15 days), Sandofan M 250 g/hl, Sandofan M8 300 g/hl and, finally, Ortho 9955 250 g/hl gave very good results. Galben-Z 8-65 300 g/hl and Galben-M 8-65 300 g/hl showed a satisfactory protection. The remaining, Vinicur M-SC 350 g/hl and Alper 250 g/hl, were not satisfactory. None of the chemicals used was phytotoxic.
