The ear rot severity of nine maize hybrids and the accumulation of fumonisin B 1 (FB 1 ), fumonisin B 2 (FB 2 ), beauvericin (BEA) and fusaproliferin (FP) after artificial inoculation in the field with a toxigenic strain of Fusarium proliferatum have been investigated. Different degrees of ear rot were observed in different hybrids. Inoculated ears contained 11–38% of Fusarium ‐damaged kernels (FDK). Mycotoxin analyses showed a pronounced contamination of FDK with concentrations ranging from 116 to 343 mg kg −1 for FB 1 , from 8 to 29 mg kg −1 for FB 2 , from 1 to 14 mg kg −1 for BEA and from 2 to 10 mg kg −1 for FP. Lower levels of contamination were found in healthy‐looking kernels (up to 26, 2, 0.2 and 0.3 mg kg −1 for FB 1 , FB 2 , BEA and FP respectively). A good correlation was observed between mycotoxin contamination and the Fusarium ear rot index, calculated on the basis of average ear infection with a scale ranging from 0 to 500 to represent healthy cobs and totally rotted cobs respectively. © 1999 Society of Chemical Industry
