Abstract Pepper crop (capsicum annum) is considered one of the most important economic vegetable crops and one of the most important crops in {Family: Solanacae }. Pepper fruits has a huge nutritional value as it contains a huge amount of vitamins C and E and a big amount of antioxidants than lemon. - Identification of the pathogen:- Pepper plants were attacked by many of the fungal diseases which caused death of pepper plants. Fusarium wilt which caused by Fusarium oxysporum f. sp. capsici is considered one of the most important and dangerous disease among them at all. Symptoms of this disease represented in discoloration on the lower leaves moves to the top, general wilt on the pepper leaves and stem and darken roots. It was noticed that the most important symptom of this pathogen is causing a visible vascular discoloration in xylum tissues. Fusarium wilt sometimes caused wilt on one of the branches without the others. The growth temprtature of Fusarium oxysporum f. sp. Capsici is quite high. This study presented many ways to control the pathogen to save the important economic value of pepper crops. To avoid the dangerous effect of the chemical fungicides, some of (bio-control agents, plant water extracts, essential oils and nano-particles materials) were applied as the chemical fungicides has a dangerous effect on the human health. Collecting the infected pepper samples:- Infected pepper samples which showed wilt symptoms previously noticed from different locations in three governorates in Egypt ( Menufia, Kafr El-sheikh and Beheira). Isolation and purification of the pathogen:- Isolation and purification of the pathogen were carried out in the department of plant pathology, faculty of agriculture, Menufia university. 20 purified isolates of Fusariumwere obtained and microscopically identified. Pathogenicity test of the obtained 20 FUSARIUM isolates:- Pathogenicity test of the pathogenic isolates was carried out in department of vegetables pathology, institute of plant pathology, agriculture research center in Giza. Soil was infested by the pathogen and irrigated for a week then pepper seedlings were transplanting in it. Number of the dead plants was measured every week for 90 days. Plant height, fresh weight and dry weight were measured also after 90 days from transplanting. Results of the pathogenicity test also showed that all of the 20 isolates were effective against the pathogen, but isolate (5) was the most effective one so it was selected to apply the different control ways on it. In this study four ways with 15 treatments were applied:- 1- Bio-control agents {T. asprillium, T.harizianum, T.viride, B. subtilis and B. cereus}. 2- Plant water extracts {sweet pepper, hot pepper, garlic and mint}. 3- Essential oils {clove, mustard, mint and thyme}. 4- Nano-particles materials {Calcium oxide and Zinc oxide}. These control treatments were applied and compared with negative control, blank control and the fungicide (Mon-cut 25%). Firstly, using of bio-control agents to control the pathogen:- Results indicated that T. asprillium was the most effective bio-control agent comparing with the control followed by T. harizianum in the meantime T. viride and B. subtilis showed a meditative effect on the pathogen while B. cereus showed a weak effect compared with the control. Using of plant water extracts:- Plant water extracts of sweet pepper, hot pepper, garlic and mint at the concentrations of 6, 9 and 12% were used to control Fusarium wilt. Results showed that sweet pepper extract was the most effective plant water extract followed by hot pepper. however, garlic and mint extracts showed a little effect of controlling the pathogen. In all cases all of the used plant water extracts were significantly reduced the growth of the pathogen comparing with the control. Using of essential oils on the pathogen:- Results also determined that {clove, mustard, mint and thyme } essential oils were very effective in controlling the pathogen. These four essential oils were applied at the concentrations 500, 600 and 700 ppm. Clove oil showed a very effective result against the pathogen followed by mustard oil while that mint and thyme oils showed a weak effect on the pathogen. Role of nano-particles materials in controlling the pathogen:- In this study, nano-particles materials had a significant and noticeable impact on the pathogen. Calcium oxide (CaO) and Zinc oxide (ZnO) nano-particles were used in this study at the concentrations 100, 200 and 300 ppm to control the pathogen. Results indicated that both of them significantly reduced the growth of the pathogen at the concentration 200 ppm but it was noticed that (CaO) was more effective than (ZnO) in both seasons 2017 and 2018.
