- Abstract
Soil-borne fungal pathogens are considered the most critical pathogens responsible for the enormous losses in chili crops. The diseases caused by them are often challenging to control due to different incidence level and limited knowledge of their epidemiological features. Advanced accessibility and a simple application process for chemical control systems have made it practical and widely accepted. In the present study, ten different fungicides viz., Shincar, Antracol, Alliete, Ridomil Gold, Moncut, Systhane, Kocide, Evito, Nativo, and Topsin M at 200, 400, 600, 800, and 1000 ppm concentrations were tested in in vitro by poisoned food method against Rhizoctonia solani, Verticillium albo-atrum and Macrophomina phaseolina. Our results showed that Nativo and Evito at 800-1000 ppm and Systhane and Kocide at 1000 ppm can significantly inhibit the mycelial growth of R. solani leading to 100% growth inhibition. Additionally, three fungicides, namely Systhane, Shincar, and Topsin M, were highly effective at all concentrations and caused 100% growth inhibition of M. phaseolina, followed by Antracol (87.22%) at 800 ppm. The Nativo, Evito and Moncut were moderately effective at 1000 ppm, causing more than 78% mycelial growth inhibition of M. phaseolina. Moreover, the ten fungicidal treatments were considerably effective against V. albo-atrum, with Moncut and Shincar being the most effective at all concentrations. This was followed by Evito (86.66%), Kocide (80%), and Systhane (79.94%) at 1000 ppm. While Topsin M and Systhane caused the slightest inhibition, i.e., 17.52% and 10% at 200 ppm. The chemicals demonstrated an escalating inhibitory trend as the concentration increased further.
