Efficacy of Fungicides against Colletotrichum lindemuthianum (Sacc. & Magn.) Bri. & Cav. causing Anthracnose of French Bean

Abstract

to evaluate the efficacy of different fungicides against Colletotrichum lindemuthianum (Sacc. & Magn.) Bri. & Cav. causing anthracnose of french bean using poisoned food technique. Among the contact fungicides tested, mancozeb and copper oxy chloride showed cent percent inhibition of mycelial growth (1000, 2000 and 3000 ppm) and was significantly superior over all other treatments. Carbendazim, thiophinate methyl, propiconazole and tebuconazole (systemic fungicides) recorded complete (100 %) inhibition of mycelial growth of C. lindemuthianumat 500, 1000 and 1500 ppm. Cent percent mycelial inhibition was recorded by combi product fungicides viz., (carbendazim + mancozeb), (tricyclazole + mancozeb) and (carboxin + thiram) followed by 88.9 per cent in (captan + Hexaconazole) at 500, 1000 and 2000 ppm.
