The present work was conducted at the Economic Entomology & Agricultural Zoology Department, Faculty of Agriculture, Menoufia University during 2020-2021 under laboratory conditions. The objective of the present study was to investigate the toxicity and biochemical effects of the ethanol extract and nanoparticles (NPS) of rosemary on the nymphs and adults of the American cockroach. The results demonstrated that the LC 50 values of nanoparticles of rosemary extract were the most toxic for the two stages than the rosemary ethanol extract. LC 50 values for nanoparticles extract were 118.22 and 112.33 ppm when contact and feeding technique were applied for nymphs, respectively, while for adults were 127.41 and 121.12 ppm when contact and feeding technique were applied, respectively. Additionally, these compounds had biochemical effects, which generally led to a decrease in the total content of protein and an increase in the total content of carbohydrates and lipids. Moreover, the activity of the acetylcholinesterase enzyme was increased. In general, the treatment with feeding was more effective than contact treatment.","PeriodicalId":168502,"journal":{"name":"Egyptian Journal of Crop Protection","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125153857","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}

The objective of this study was to evaluate the efficacy of five plant extracts, three Trichoderma isolates, and two systemic fungicides in controlling Fusarium wilt infestations under laboratory and greenhouse conditions. In vitro tests revealed that all of the plant extracts tested exhibited fungicidal activity against F.oxysporum f.sp. phaseoli, albeit to varying degrees of efficacy. Cuminum cyminum and Dianthus caryophyllus aqueous extracts were the most effective against Fusarium. All three Trichoderma isolates inhibited the mycelium growth of the pathogen. Furthermore, the efficacy of two systemic fungicides (Rizolex-T and Topsin M) were investigated and both tested fungicides reported a significant reduction in the growth of the pathogen compared to the control. In vivo evaluation the results showed that all tested agents were effective in reducing wilt incidence (pre-and post-emergence, survival of plants, and severity of infection) and increasing some vegetative growth parameters of bean plants (plant height, number of branches, and number of leaves/plants) compared to the infected control. In comparison to synthetic fungicides, our study demonstrated that the use of aqueous plant extracts could be an applicable, safe, and costeffective method for controlling F. oxysporum f.sp. phaseoli. In addition, our study found that local isolates of T.harzianum, T. asperellum, and T.viride have the potential to be used as biological control agents against F. oxysporum f.sp. phaseoli.","PeriodicalId":168502,"journal":{"name":"Egyptian Journal of Crop Protection","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130342211","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}
