The reduction, we investigated the occurrence <strong>of</strong> mycotoxin-producing Fusarium<br />
fungi on forage rice and the changes <strong>of</strong> fumonisin (FUM), deoxynivalenol<br />
(DON)nivalenol (NIV) and zearalenon (ZEN) in forage rice in Japan.<br />
Two rice cultivars, early maturing (A) and late maturing (B), were grown in a<br />
paddy field in Tochigi, Japan, 36.92°N, 139.93°E in 2011. The plants were<br />
sampled from heading stage to full-ripe stage. The Fusarium fungus on the plants<br />
was isolated and identified, and a qualified analysis <strong>of</strong> FUM, DON, NIV and ZEN<br />
in the plants was performed using an LC/MS/MS system.<br />
Eighteen Fusarium fungi were isolated from cultivar A, including 7 <strong>of</strong> F. fujikuroi<br />
(all FUM-producing), 5 <strong>of</strong> F. asiaticum (4 producing ZEN, 2 producing NIV and 2<br />
producing DON). Seven were isolated from cultivar B, including 4 <strong>of</strong> F. fujikuroi (all<br />
producing FUM) and 1 <strong>of</strong> F. graminearum (DON and ZEN-producing). These<br />
Fusarium fungi were isolated from the head but also from SL from the heading<br />
stage to the full-ripe stage in both cultivars. The concentration <strong>of</strong> FUM (as FUM<br />
B1) in the heads <strong>of</strong> cultivar A ranged from ND (
