Abstract EN
Laboratory and field studies were conduc ted to evaluate the efficiency of growth retardant Cultar (Paclobutrazol), sewage sluge, fungicides Score and their combination against Alternaria solani the causal agent of early blight disease of tomato in Potato Sucrose Agar (PSA) media and under field condition.
The combined effect of three materials on the pathogen was also evaluated.
Results have showed-fehat Cultar was significantly effective in reducing the growth of Alternaria.
solani in PSA, at the concentration rate of 0,5,10,15,20,25 and 30 ppm.
The highest growth inhibition percentage was (79.5%) obtained at a concentration of 30 ppm.
Inhibition percentages were increased as the concentrations of cultar increased.
The effect of Cultar and Score when used alone or mixed with lonely or with their combination with the fungus each other, resulted in a significant decrease in the infection severity on four tomato cultivars contaminated with the fungus A.solani under field conditions .The infection severities for the cultivars: Hymer , Gs-12,1PA-S25 and IPA-1008 were 20.08* 23.90, 23.78 and 21.95 respectively, and the infection rate(r) (0.05, 0.05, 0.04 and 0.05) compared for the same cultivars .In contrast, the infection severities of the fungal treatment alone was 56.23, 65.58, 59.75 and 71.35% and the infection rates (r) were 0.08, 0.10, 0.09 and 0.11 for the same cultivars.
Results also indicated that sewage sluge treatment was not significantly effective in decreasing the infection severity.
