Distribution and production of toxins by fungi from the genus Fusarium from infected cereals causing fusariosis on cereals grain in Moscow region

9 Fusarium species and 2 subspecies isolated from 83 samples of cereals (wi nter wheat, triticale, rye, oat and barley) harvested in Moscow region were F. culmorum. F, avenaceum, F. sporotrichioides. F. poae. F. equiseti. F. m oniliforme var. subglutinans, F. tricinctum. F. graminearum. F, sambucinum, F, sambucinum var. coeruleum. F. acuminatum. 4 Dominant species F. culmorum (43.6 % of isolates), F. avenaceum (23.1 %), F. sporotrichioides (12.0 %) and F. poae (7.7 %) were tested for productio n of 9 toxin (deoxynivalenol, DON; 3-acetyldeoxynivalenol. 3-ADON: nivaleno l, NIV; T - 2 toxin, T - 2; zearalenone, ZON; moniliformin, MON; butenolide 5-actamido-2(5H)-furanone, 5-AAF; fusarin-C, FUS-C;, chlamidosporol, CHLSP ). Toxins produced included: DON by 9/11 F. culmorum isolates (average level 2 4.5 mg/kg g grain), 3-ADON - 5/11 F. culmorum (250.5 mg/kg), NIV - 1/4 F. p oae (35.0 mg/kg), T-2 - 7/7 F. sporortichioides (0.97 mg/kg), 1/4 F, poae ( 0.04 mg/kg), ZON - 3/11 F. culmorum, FUS-C - 5/11 F. culmorum, MON - 9/11 F . avenaceum (191.1 mg/kg), 5-AAF - 4/11 F. avenaceum (27 mg/kg), CHLSP-3/11 F. avenaceum.
