Abstract
A study was conducted during 2 years to determine the effects of three different control measures on the development of Verticillium wilt on olive trees cv. ‘Nabali’ at Al-Hallabat, Jordan. The causal agent of the wilt wasVerticillium dahliae Kleb. Treating diseased trees with Cryptonol (8-hydroxyquinoline sulfate) in a soil drench, or covering trees with a solar chamber for 15 days, was effective in suppressing disease development. The fertilizer treatment (NPK, 15:15:30) decreased disease severity and percent infection. All decreases are in comparison with the untreated control, and as recorded during the active phase of the pathogen. The treatments did not differ significantly from each other, and disease incidence in treated trees remained lower than in the control throughout the examined period.
