In pot and field experiments carried out in 1979-1981, the systemic funqicide hymexazol prevented satisfactorily soil borne damping-off of sugar beet caused mainly by the fungus Pythium debaryanum auct. non Hesse. The results with the combination hymexazol + thiram were still better. This treatment gave very good protection against the disease up to about two to three weeks after emergence, increased the yield on the average by 5-10 % and produced considerably thicker and denser stands. Thereafter a large number of beets may have become infected, but no great damage was caused as only few died. Band spraying at emergence using hymexazol with a large amount of water as well as spraying into the seed furrow prevented the outbreak of the disease almost completely. Liming had little effect on damping-off. Introduction In modern sugar beet cultivation, the method of sowing to stand has become common. According to DUNNING (1970), the fungicide treatment of sugar beet seed is commonly applied in most countries and cannot be dispensed with, because damping-off is considered one of the most significant diseases of beet. In Europe during 1968-1970, the greatest losses due to damping-off occurred in Poland, Romania, Czechoslovakia and Hungary. In Ireland, too, the disease was reported to be severe (DUNNING 1970). In 1979-1980, the main disease-causing factors at the seedling stage in 16 European countries were in the decreasing order of frequency: Phoma (13), Pythium (13), Aphanomyces (8), Rhizoctonia (6), Fusarium (3), Alternaria (2) (DUNNING & HEIJBROEK 1981). In controlling the seed borne damping-off of sugar beet, seed dressing with mercurial compounds or thiram has been predominating (GATES & HULL 1954, GATES 1959, NOLLE 1960, LUDECKE & WINNER 1963, LINNASALMI 1970, MÖLLERSTRÖM 1974). However, maneb and mancozeb have
