Abstract: Khairpur is the biodiversity center of date palm in Pakistan. The date palm orchards are suffering from a sudden decline disease (SDD) problem caused by a soil born fungus Fusarium solani, which is threatening date palm industry in this region. The efficacy of six different fungicides was tested against Fusarium solani under In vitro and In vivo conditions to control the sudden decline disease of date palm. The experiment was arranged in Randomized Complete block Design (RCBD) in the lab and Randomized Complete Block Design (RCBD) in field conditions. Bavistin D.F showed complete suppression of Fusarium solani followed by Topsin-M, Aliette and Ridomil gold at 150 ppm concentration followed by 100 ppm and 50 ppm. The maximum mean colony growth was recorded in control medium (17.8) followed by Copper oxychloride at 50ppm (15.1). The Bavistin D.F proved to be the highly effective fungicide also under field conditions followed by Topsin-M, Aliette, Ridomil, Mancozeb and Copper oxychloride. In untreated control plants, disease severity was increased with increase in time. The treated plants recovered and produced fruit next season.
