Fragaria Chiloensis

The F1 generation of selfed plants of Fragaria chiloensis, F. ovalis, and F. yukonensis contained seedlings resistant to the verticillium wilt disease. Selfed F. orientalis plants yielded seedlings that carried considerable tolerance but selfed F. vesca, F. bracteata, and F. virginiana plants yielded neither tolerant nor resistant seedlings. Asexually propagated plants of the seven species were all susceptible to the disease.

Verticillium Albo Atrum

Apricot trees often recover from the "black heart" disease incited by the fungus Verticillium albo-atrum Reinke & Berthold, and a characteristic of such resistant trees is that the infected wood becomes dark brown to black in colour (Dufrenoy and Dufrenoy 1927). The fungus dies 1-6 months after it has colonized the wood (Taylor 1963). Analysis of total phenolics by the Folin-Denis assay showed an approximate fivefold increase (to about 60 mgjg wood) compared with that of uninfected wood of the same branch, and suggested their involvement in disease resistance mechanisms.

Plot Design

Screening of upland cotton genotypes against Verticillium wilt disease was conducted. The 268 upland cotton genotypes (Carmen and Acala Maxxa cultivar were tolerant- control while cvs. Cukurova 1518 and Acala SJ2 were susceptible-control) were screened against defoliating (PYDV6) and non-defoliating (Vd11) pathotypes of the fungus in a randomized plot design with four replications in growth chamber. Field experiment was established according to the augmented experimental design. Variance analysis was significant (p ≤ 0.05) for all traits against Verticillium wilt. Cvs. Semerkant Uzbek and Taskent 6 were more tolerant than the tolerant-control cultivars against both pathotypes. Most of the genotypes were tolerant in field trial in terms of disease severity that was the lowest for STN K311 genotype in both periods. The highest seed cotton yield was obtained in genotypes as BA119, Okra 204, H-23, Gedera-5, PI 528420 and Acala Royale, which were moderately tolerant to the wilt disease.

Medicago Sativa L

Barrier is the first Canadian cultivar of alfalfa (Medicago sativa L.) developed with resistance to verticillium wilt disease. It also has very good resistance to bacterial wilt. Barrier is adapted to the irrigated areas in Southern Alberta and British Columbia where these diseases are prevalent.Key words: Medicago sativa L., alfalfa, cultivar description, verticillium wilt, bacterial wilt

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.
