English Abstract

This experiment was carried out to demonstrate the efficiency of the fungus resistance Glomus mosseae With chemical fungicides Tachigaren , Topsin and Raxil.

In the control of root rot disease on six local varieties of Iraqi wheat, using the design of the whole random sectors RCBD .the treatment of (Tachigaren with mycorrhizal fungus G.

mosseae of the pathogen Fusarium solani ) superior on other treatments in chlorophyll content, shoot and root dry weight، resulting in 30 spad 13.17g and 3.12g in the cultivars Sham6، Rabea، Rabea and Ibaa99، respectively، which recorded in present of the pathogen alone which were 10.33 spad in Aras 2.91g in Sham4 and 0.47g in Aras، respectively.

The same treatment (Tachigaren with mycorrhizal fungus G.

mosseae of the pathogen Fusarium solani )in the infection severity which was the lowest in Rabeaa (0.12) while the highest was 0.84 in Sham4 with the pathogen.

All the studied cultivars treated with (Tachigaren + G.

mosseae+ pathogen) superior on the percentage of mycorrhizae infection، compared to Topsin and Raxil، maximum mycorrhizae infection was 84.45% in Rabeaa compared with minimum infection 36.63% in Sham4.The results that Systemic Resistance Induction (SRI) showed the induction in all treatments compared with negative control، the highest SRI recorded in treatment of (G.

mosseae+ F.solani) in which the chitinase and poly phenol oxidase were 4.05 and 2.2 units/ml for the Rabeaa and Sham4 compared with the lowest these enzymes activities (0.05u/ml in Aras) and (0.04u/ml in Ibaa99)، respectively grain wt./plant and wt.

of 100 grains showed superiority of treatment (Tachigaren + G.

mosseae + pathogen) treatment resulting in.

In addition، the results showed that wheat productivity included)، (21.46 and 20.72g in Sham6 and Rabeaa) and (4.81 and 4.41g in Rabeaa and Sham6 ) compared to the lowest values in present of the pathogen F.solani 3.52 and 1.37g Ibaa99 and Arass cultivars، respectively.
