Molecular identification of Fusarium spp. isolated from tomato plant in Iraq and China

Abstract EN

This study was conducted to identify Fusarium spp.

isolated from tomato plant in Iraq and China.

A total of 12 isolates from Iraq (1-12) and four isolates from China (M1-M4) were used in this study.

Based on Morphological characteristics (color, growth pattern, Macro and Micro-conidia shape) high differences between Fusarium isolates were found.

Sensitivity test to the fungicide carbendazim revealed that one third of isolates(4 / 12) from Iraq had EC50 values over than 1000µg/ml indicated that many Iraqi isolates have developed resistance to carbendazim.

Based on ITS sequences, Fusarium isolates were identified as follow, isolates 1, 3, 5, 6, 7, 10 were identified as Fusarium oxysporum, isolates 8, 11 as F.

solani, isolates 12, M1 and M3 as F.

moniliforme, isolates 2, M2 and M4 as F.

proliferatum, F.

chlamydosporum and F.

kyushuense , respectively.
