Efficacy of Fungicides against Drechslera setariae Causing Leaf Spot Disease of Pearl Millet Pennisetum glaucum (L.) in vitro condition

Abstract

The present investigations were carried out to study the effects of selected fungicides viz. Dithane M-45, Tilt, Score, Kavach, Contaf, Companion and Folicur on mycelial growth of Drechslera setariae in vitro. The result revealed that all the fungicides viz., Dithane M-45, Tilt, Score, Kavach, Contaf, Companion and Folicur, significantly inhibited the mycelial growth of D. setariae at 1, 10, 50, 100 and 200 ppm. Tilt was most inhibitory proved followed Folicur and Tilt to mycelial growth of D. setariae in vitro. Out of seven fungicides tested under field conditions to manage leaf spot disease of pearl millet. Tilt (0.2%) and folicur (0.2%) provided effective against this disease. There was significant increase in the grain yield of these two treatments.
