The efficiency of these essential oils along with their formulations were compared against the bean aphid, Aphis fabae (Scopoli). Results disclosed that all EC preparations passed the emulsion stability and foam formation tests. The particle droplet size of the nanoemulsions varied from 64.3 to 264.7 nm. The toxicity of EC formulations was slightly higher than the corresponding nanoemulsion formulations. Both EC and nanoemulsion of R. palmatum were the most efficient (LC50 = 1003.60 and 1105.34 mg L−1, respectively). EC preparations had no adverse effects on seed beans. The absence of organic solvents and the high aphicidal activity of EC formulations might make these preparations suitable for controlling A. fabae.","PeriodicalId":8323,"journal":{"name":"Archives of Phytopathology and Plant Protection","volume":"56 1","pages":"187 - 208"},"PeriodicalIF":1.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47150166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instead of the M-haustorium, a collar was created around the D-haustorium. A neck encasing developed in both types of necrotic haustoria. This encasement may serve as the host cell’s protection against toxins created after the death of haustoria. The severe changes in the chloroplasts and nuclei of this host plant after infection by this pathogen may give this pathogen the possibility of controlling this serious weed.

Under greenhouse conditions, wheat seeds treated with isolate P58 and T2 separately reduced the severity of crown rot disease significantly and improved the growth parameters of wheat seedlings as compared to control. The combined use of Pseudomonas azotoformans and Trichoderma gamsii increased the effectiveness of the antagonists and promoted wheat growth.

Accordingly, eight plant parasitic nematode genera were identified, including Meloidogyne, Pratylenchus, Helicotylenchus, Scutellonema, Rotylenchulus, Criconema, Paratylenchus, and Globodera. The highest prominence value was recorded for Meloidogyne and the lowest being for Paratylenchus. In terms of Meloidogyne infestation, the highest mean root knot incidence was in the Dedo district, specifically at the Babo peasant association, where Meloidogyne could be considered a major threat to tomato production. The study further indicated that Meloidogyne density was higher in soil with a pH between 6.4 and 7.4, and an altitude above 1800 m.
