In studies with 58-76 Israeli isolates and 5-9 foreign isolates of F. moniliforme, growth in vitro on wheat and PDA was best at 24-30° C, with little growth at 6° C and none at 40° C. In the optimal temperature range, equal growth was made in light and darkness. F. moniliforme is widespread in agricultural soils in Israel, but in some 170 samples rarely exceeded about 5 % of the total Fusarium population. Of seventy-six Israeli and nine foreign isolates, seventy-four induced toxic reactions on rabbit skin. This is an unusually high proportion. The histological changes induced by such skin application are described. Inoculation tests were performed with eighty-three Israeli isolates from six field and five fruit crops, and with thirteen foreign isolates (including six from varieties of F. moniliforme) on ten crop plants. Onions and all dicotyledonous plants tested were affected by a high proportion of the isolates, while wheat was not, and maize was little affected. There was therefore little pathogenic specialization among these isolates. The studies carried out in Israel on F. moniliforme as cause of the "black heart" disease of banana fruits and of fruit rots of avocado and citrus are reviewed. Morphological studies of all Israeli isolates and of those received from abroad, and a survey of the literature on the taxonomy of the Liseola section of Fusarium, have led to the following conclusion: The section should contain F. moniliforme as its only species, and F. moniliforme var. anthophilum and F. moniliforme var. subglutinans as its only two varieties. From the present distribution of F. moniliforme and its environmental relationships it is concluded that this fungus constitutes a potential danger to crops in warm countries to which irrigation is being introduced, and especially to dense plantation crops. © 1973 Dr. W.
