Abstract
Capsicum annuum L. member of family Solanaceae is an important vegetable crop throughout the world. Fusarium wilt of chilli caused by Fusarium oxysporoum f.sp. capsici, is a serious destructive disease, which reduces its yield and is a major threat to the economy. Plant activators play an important role to manage soil born disease. In current study, a pot experiment was carried out under greenhouse conditions in the research area of Plant Pathology Department, University of Agriculture, Faisalabad. Five plant activators K2HPO4, CaCl2, Benzoic acid, Salicylic acid and Alpha-Tocopherol were used to manage the Fusarium wilt of chilli. Soil drenching of each plant activator was applied at three different concentrations 0.25%, 0.5% and 0.75% after transplantation. Results showed that the minimum incidence of disease, maximum length of shoot, length of root was revealed by K2HPO4 at 0.75% concentration. While benzoic acid exhibit maximum shoot fresh weight, maximum shoot dry weight, fresh root weight and dry root weight at 0.75% concentration. Maximum fresh leaf weight showed by salicylic acid whereas maximum dry leaf weight exhibited by alpha-tocopherol at 0.75% concentration. It was concluded that K2HPO4 at 0.75% concentration is effective to manage Fusarium wiltof chilli that can be used to manage disease in future.

Summary
Capsicum annuum L. is the second most important vegetable crop of Solanaceae family which is cultivated throughout the world. (Basu and De, 2003; Ali et al, 2018) It is a nutritionally important vegetable crop used in the human diet, rich and cheap source of nutrients, used as vegetable, fresh fruit, dry spice and pickled all over the world (Nawaz et al, 2017; Madbouly and Abdelbacki, 2017). Chilli is used to cure cough and cold, sore throat, asthma, sinus infection, cancer, regulate blood circulation, varicose veins, anorexia, liver congestion, haemorrhoids and helpful in digestion (Gantait et al, 2012; Huang et al, 2013; Yousaf et al, 2017) It contains vitamin A, C, E, K and B6, riboflavin, betaine, thiamine, niacin, choline, folic acid, folate, pantothenic acid, ascorbic acid and beta carotene (Ali et al, 2018). That’s why present study was carried out with the objective to check the efficacy of different plant activators against the fusarium wilt of chilli
