The efficacy of various fungicides against the tomato early blight (Alternaria solani)

Abstract

The tomato is one of the most popular vegetables farmed worldwide. One of the most harmful tomato diseases is early blight, which is a disease that the fungus Alternaria solani causes.This will reduce the quality and quantity of tomatoes. Nearly 80% losses were reported due to this disease. To evaluate the fungi-toxic activity of the fungicides Kavach, Cbrio Top, Merivon, Avtar, Amistar, and Tilt at the plant pathology department of the faculty of agriculture at LPU, Punjab, over the years 2021–2022, the poisoned food approach was adopted. Six different fungicides were checked at different concentration like 50, 100, 150 ppm at lab condition. Propiconazole (Tilt) was found to be most effective, i.e. percent inhibition was 100%. Same fungicides were checked at field.Among this fungicides Cbrio Top, Merivon, Amistar were found to be most effective followed by kavach, Tilt and Avtar.
