Abstract:
This research aimed to study the effect of salicylic acid on development of infection with races 0 and 2 of Fusarium oxysporum f.sp. ciceris on chickpea cultivar Ghab4. Studying the antifungal antagonism of salicylic acid for races through Poisoned Food Technique, ten concentrations were prepared from 1 to 2000 µg/ml on PDA, the inhibition percentage was calculated. The half-field experiment was carried out under the natural conditions of Al-Ghab region at the Agricultural Scientific Research Center, 2021, with a Complete Random Block Design with three replications and three treatments: seed coating, seed soaking, and spraying the plants with salicylic acid in addition to the control. The percentage and severity of infection were recorded on plants at the age of 80 days. The results showed an increase in the percentage of inhibition by increasing the concentration of salicylic acid in PDA culture, the two concentrations of 1000 and 1500 µg/ml completely inhibited the actinic growth of races 0 and 2 (respectively). The use of salicylic acid was not highly effective in reducing the percentage and severity of infection resulting from infection with race0, while the soaking had significant differences over each of the spraying and coating, followed by the spraying with significant differences with the control infected with race2.
Key words:Ghab4 cultivar, Fusarium oxysporum f. sp. ciceris, salicylic acid, race0, race2, AL-Ghab.
