Twenty-nine Fusarium isolates, representing three new taxa originated by Nirenberg from F. sambucinum Fuckel sensu lato, namely: F. sambucinum Fuckel sensu stricto, F. venenotum Nirenb., and F. torulosum (Berk. & Curt.) Nirenb., were tested for in vitro production of toxic secondary metabolites on autoclaved corn kernels. F. sambucinum sensu stricto was able to produce type A trichothecenes and enniatin B (EB). In particular, amongst the 14 isolates tested, 5 produced only diacetoxyscirpenol (DAS) (up to 700 micrograms/g); 1 produced only neosolaniol (NEOS) (250 micrograms/g); 2 produced T-2 toxin (T-2) + NEOS (up to 175 and 150 micrograms/g, respectively); 1 produced NEOS + DAS (300 and 100 micrograms/g, respectively); and 5 produced DAS + EB (up to 500 and 140 micrograms/g, respectively). All six isolates of F. venenotum were able to produce only DAS (up to 100 micrograms/g). F. torulosum produced no trichothecenes, but four out of nine tested isolates were able to produce EB (up to 140 micrograms/g). Zearalenones and type B trichothecenes were not found. The toxicity of the culture extracts towards Artemia salina L. was correlated in general with the occurrence of the above toxins, except for some F. torulosum strains. However, the lack of correlation between the amounts of toxins recovered and toxic activity observed in the Geotrichum candidum Link ex Pers. and A. salina assays suggested the presence of unknown toxic compounds.

The yield of diacetoxyscirpenol (DAS) production by F. sambucinum strain No KF 735, isolated from potato tuber with dry rot symptoms, cultured on solid media and on liquid medium, has been examined.The amount of DAS produced within 28 days at 25°C in the cultures grown on solid media (wheat, rye, rice, oats, corn, barley, triticale and malt) reached 238mg/kg±9 to 789±16mg/kg (mean ± standard error; n=3), on potato cubes -55±3mg/kg and on the potato extract -147±5mg/dcm(3).The best substracts for crystalline compound production were malt and barley grain.

The paper presents 21Fusarium species occurring in Poland on the field crops /mostly on cereals, maize, potato and Papilionaceae plants/, woody plants, grasses, vegetables and ornamentals as well as on kernels or seeds of these hosts and soils. Additionally the commonly observed symptoms on above-mentioned plants and the informations about regions of the highest disease occurrence are added.However the paper results mainly from authors' investigation on theFusarium species occurrence in Poland, it encloses also the available, post-war literature data on the fusariosis in Poland in the past.Majority ofFusarium species cited had been identified according to Nelson et al, taxonomic system. Comparative listing of the monographs / 1,11, 21/ is presented.
