Detection frequency (a) and level (b) of Fusarium moniliforme from imported untreated seeds, 1990-97.Colonies on PSA at ART (28–30 °C) are spreadingand grow moderately fast, attaining a 5.30-cmdiam in 5 d. They are azonated, floccose with serratemargins, and white tinged with pink at the center.The colony on the reverse side of the agar plate isslightly zonated and white with a purplish tinge at thecenter. At 21 °C under alternating 12-h NUV lightand 12-h darkness, colonies grow moderately fastand attain a 5.34-cm diam in 5 d. They are slightlyzonated, floccose to slightly felted with serrate margins,and purplish at the center and light purple outward.The colony on the reverse side of the agarplate appears slightly zonated and white to creamy.At 28 °C under alternating 12-h fluorescent light and12-h darkness, colonies grow moderately fast andattain a 5.90-cm diam in 5 d. They are slightly zonated,densely floccose with serrate margins, andwhite; they later become creamy at the center. Thecolony on the reverse side of the agar plate is slightlyzonated and white to creamy.Colonies on OA at ART (28–30 °C) grow moderatelyfast and attain a 5.78-cm diam in 5 d. Theyare azonated and floccose to deeply felted with evento slightly sinuate margins. Colonies are white andbecome purple at the center. The colony on the reverseside of the agar plate appears azonated andwhite with dark purple centers. At 21 °C under alternatingNUV light and 12-h darkness, colonies growslowly and attain a 4.93-cm diam in 5 d. They arezonated, slightly felted with even margins, and whiteto purple. Saltation of colonies was observed in someplates. The colony on the reverse side of the agar33
