The aim of this study was to examine the efficacy of Chitosan and Chitosan nanoparticles to control chocolate spot disease caused by Botrytis fabae on faba bean (cv. Giza 40) under field conditions. Spraying Chitosan or Chitosan NP (30, 45, 60 after sowing) significantly decreased chocolate spot disease severity to 8.7% compared to 22.3 for the untreated control which was not significantly different from the fungicide Mancozeb which exhibited 10.17% disease severity. This was accompanied with an increase in totals phenols in Chitosan NP treated plants to 4.43 mg compared to 0. 436 for the untreated control. Also, this was accompanied with an increase in polyphenol and peroxidase activity to be as high as 0.399 and 0.394 compared to 0.133 and 0.130 (absorbance/min./g f.w.), in the untreated control, respectively. Meanwhile, use of Chitosan and Chitosan NP significantly improved faba bean vegetative growth, i.e . plant height, number of pods, as well as seeds yield per plant compared to the untreated control with more superiority for Chitosan NP.","PeriodicalId":21277,"journal":{"name":"Revista de Ciências Agrarias - Amazon Journal of Agricultural and Environmental Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88283704","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 in vitro antifungal activity of chitosan and its ability to elicit defense responses in two faba bean cultivars Giza 416 (resistant) and Giza 40 (susceptible) against this fungus were evaluated. Seven isolates of B. fabae were cleaned from infected leaves. All isolates were pathogenic to Giza 40 cultivar, with isolate 3 (Bf-3) was the most virulent. Chitosan inhibits the mycelial growth of B. fabae (Bf-3) in concentration-dependent manner. At 0.75 % and 1 %, chitosan completely inhibits the growth of B. fabae. Under greenhouse conditions, two fab bean cultivars, Giza 416 (resistant) and Giza 40 (susceptible) were sprayed with 0.5% chitosan. Treatment with chitosan 0.5% reduced the chocolate spot disease severity for both cultivars compared with untreated infected control. Plants of both cultivars treated with chitosan showed a lower rate of lipid peroxidation and higher levels of chlorophyll and total phenols compared with untreated infected control. Chitosan stimulated the activity of defense enzymes such as peroxidase (POD), polyphenol oxidase (PPO), and phenylalanine ammonia-lyase (PAL). Furthermore, chitosan treatment increased the expression levels of three pathogenesis","PeriodicalId":21277,"journal":{"name":"Revista de Ciências Agrarias - Amazon Journal of Agricultural and Environmental Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85126754","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}
