- Abstract
Chili (Capsicum annum L.) is very valuable crop all over the world as well as Pakistan. It is commonly cultivated in subtropics and temperate regions. Damping off disease in chili caused by Pythium aphanidermatum is responsible for a potentially serious threat towards seedling mortality in both nurseries and field crop. The present study was designed to determine the pathogen of damping-off of chili and its management through chemicals in vitro. For this purpose, the pathogen was isolated from samples shown typical symptoms of damping-off on PDA media, purified and identified on the basis of morphological characteristics. To fulfill the Koch's postulate pathogenicity test was conducted. For the management of Damping-off disease of chili an experiment was designed where six fungicides were used i.e Contaf plus, Flint max, Score, Ellectus super, Fossil, Topsin M with three different concentrations (100, 150 and 200 ppm). to check their efficiency against isolated pathogen by using Poisoned food technique. Result showed that all the chemicals has excellent inhibition effect on growth of P. aphanidermatum at different levels, where Ellectus super expressed the best results to inhibit fungal growth (4.11mm) at 200 ppm concentration followed by Flint max (5.11mm) and Score (6.66 mm).
