Abstract EN

The results of studying the effect of some insecticides (Spinosyn, Emamectin- benzoate, Cyromazine and Flufenoxuron) on mycelial and sporulation inhibition percentage of the fungi (Fusarium avenea, Bipolaris sorkinian , Alternaria alternata, Helminthosporium sativum) showed that the mycelial and sporulation inhibition percentage were varied according to insecticides kind and fungi species.

The results of statistical analysis confirmed the existence of significant variation between the treatments.

The spinosyn exhibit the highest general mean of mycelial and sporulation inhibition percentage, which reached %45,6 and %33,75 respectively.

The fungi A.

alternata revealed the highest mycelial inhibition reached %54.78.

The general mean of sporulation inhibition of B.

sorkinian and A.

alternata reached %25,70 and %24,79 respectively in comparison with %40,17 and %40,09 for A.

alternata and H.

sativum respectively
