Abstract

Muhrez, K.A., M.Z. Tawil and B. Barhoum. 2021. Effect of Olive Mill Wastewater of in the Control of Olive Verticillium Wilt Caused by Verticillium dahlia Kleb. Arab Journal of Plant Protection, 39(4): 273-280. https://doi.org/10.22268/AJPP-39.4.273280 This research aimed to evaluate the application of olive mill wastewater in controlling Verticillium dahliae the causal agent of olive wilt disease on olive trees. This study was carried out on 2 years old olive local variety (Khderi) plants planted in pots after it has been artificial inoculated with V. dahliae, and severity was recorded within 90 days. Olive mill wastewater (omww) efficacy was estimated at the end of the experiment. Severity was increased from 8.89% before treatment to 28.89% 60 days after treatment, and decreased to 13.33% 90 days after treatment with omww 450 ml/l. Disease severity increased from 11.11% before treatment to 37.78% 60 days after treatment and decreased to 35.56% 90 days after treatment with omww 300 ml/l. Whereas, disease severity increased from 17.78% before treatment to 40% 90 days after treatment with azoxystrobin compared to the inoculated control where disease severity increased from 13.33% before treatment to 100% 90 days after treatment. Omww 450 ml/l had the highest efficacy of 80% followed by azoxystrobin 70%, and omww 300 ml/l 57.33%. It can be concluded that olive mill wastewater has a potential application as a bio-fungicide for the control of olive verticillium wilt disease.

橄榄厂废水防治大丽花黄萎的效果
Muhrez, k.a., M.Z. Tawil和B. Barhoum, 2021。橄榄厂废水防治大丽花黄萎病的效果。植物保护学报,39(4):273-280。https://doi.org/10.22268/AJPP-39.4.273280本研究旨在评价橄榄厂废水在防治橄榄枯萎病病原菌大丽花黄萎病中的应用。本研究以2年生橄榄地方品种(Khderi)为研究对象,经大丽花弧菌人工接种后盆栽种植,90 d内记录严重程度。在试验结束时对橄榄厂废水(omww)的处理效果进行了评估。治疗前患者的严重程度为8.89%,治疗后60天为28.89%,治疗后90天为13.33%。剂量为300 ml/l的omww治疗后,疾病严重程度从治疗前的11.11%上升至治疗后60天的37.78%,90天下降至35.56%。然而,与接种对照组相比,接种azoxystrobin后90天疾病严重程度从治疗前的17.78%增加到40%,而接种对照组的疾病严重程度从治疗前的13.33%增加到治疗后90天的100%。Omww 450 ml/l的效价最高,为80%,其次为唑虫胺酯70%,Omww 300 ml/l的效价最高,为57.33%。由此可见,橄榄厂废水具有作为生物杀菌剂防治橄榄黄萎病的潜力。关键词:橄榄厂废水;大丽花黄萎病菌;橄榄;
