In-vitro Management of Wilt Disease of Sugarcane Through Optimization of Chemical Fungicides

Abstract

Wilt of sugarcane caused by Fusarium sacchari, is a soil and seed borne pathogen causing heavy losses in sugarcane production to grower. Chemical control method is an effective and highly adopted approach of eliminating disease causing organism. The present study was carried out to assess the efficacy of combination fungicides in vitro condition against Fusarium sacchari causing wilt in sugarcane. Three combination (systemic fungicides) and one contact fungicide Mastercop (Copper sulphate pentrahydrate 23.99% SC), Amistar-Top (Azoxystrobin 18.2 SC + Difenoconazole 11.4 SC), Shamir (Tebuconazole 6.7 + Captan 26.9SC), Electron (Azoxystrobin 2.5% + Thiophanate Methyl 11.25% + Thiamethoxam 25% FS), Dhanustin (Carbendazim 50% WP) were tested at three different concentration (5PPM, 15PPM and 25PPM) using by poisoned food technique on OMA medium. All the fungicides significantly inhibited mycelial growth of the fungus. Maximum 100% mycelial growth inhibition was recorded in T4 Electron (Azoxystrobin 2.5% + Thiophanate Methyl 11.25% + Thiamethoxam 25% FS) at all concentrations and minimum 69.25% mycelial growth inhibition was recorded in T1 Mastercop (Copper sulphate pentrahydrate 23.99% SC) and all other fungicides significantly inhibited the mycelial growth of the fungus, observation was recorded and mentioned in the result of the paper.
