Abstract:
Potato is one of the most important vegetable crops grown in the world. The early blight of potato is common occurance wherever potatoes are grown in the world. The early blight is free from any inhibition caused by weather condition and occurs in cold as well as warm areas. An experiment was conducted to test the inhibition of six different fungicides (Propiconazole, Thiram, Carbendazim, Dithane M-45, Sulphur and Tricyclazole) for controlling the disease under in-vitro and field condition during 2021-22 and 2022-23. The highest percent disease controlled with propiconazole exhibited highest percent inhibition (100%) in radial growth and minimum percent inhibition were found in Tricyclazole (10.77%). The field evaluation of different fungicides indicated that Propiconazole (12.76%) was most effective and Tricyclazol (25.63%) least effective for the controlling the disease incidence and also economical in reducing severity of the early blight and increasing yield over control.
