Effect of botanicals and carbendazim against anthracnose (Colletotrichum lindemuthianum) of green gram (Vigna radiata L.)

Abstract

A research trial was carried out during Kharif season of 2023 at the Central Research Field, Department of Plant Pathology, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh. The experiment was conducted to evaluate the effect of different botanicals and fungicide on anthracnose of green gram caused by Colletotrichum lindemuthianum. The trial was conducted using seven treatments viz. T1- Carbendazim @ 2 g/kg seed (S.T.) + Neem oil @ 0.2% (F.S.), T2- Carbendazim @ 2 g/kg seed (S.T) + Eucalyptus oil @ 0.2% (F.S), T3- Carbendazim @ 2 g/kg seed (S.T) + Tea tree oil @ 0.2% (F.S), T4- Carbendazim @ 2 g/kg seed (S.T) + Lavender oil @ 0.2% (F.S), T5- Carbendazim @ 2 g/kg seed (S.T) + Thyme oil @ 0.2% (F.S), T6- Carbendazim @ 2 g/kg seed (S.T) + @ 0.1% (F.S.) and T0- Control with each treatment replicating three times. It was observed that all treatments significantly reduced the intensity of disease of green gram as compared to T0- Control. From the study of results, it was concluded that among all the treatments, the most effective for managing the disease was T1- Carbendazim + Neem oil (26.62%) followed by T2- Carbendazim + Eucalyptus oil (30.49), T4- Carbendazim + Lavender oil (35.37), T3- Carbendazim + Tea tree oil (38.10) and T5- Carbendazim + Thyme oil (39.97) as compared to treated check T6- Carbendazim (S.T) + Carbendazim (F.S.) (20.03%) and non-treated check T0- Control (41.77%).
