Abstract Laboratory experiment was conducted to test the possibility of combining Trichoderma harzianum a potential bio-control agent with fungicides commonly recommended viz., captan, thiram, carbendazim and thiophanate methyl for seed treatment against soil borne diseases. Maximum inhibition (100%) was recorded with carbendazim @ 0.1 and 0.2 per cent concentration at 24 hrs. incubation followed by 96.88 and 88.44 per cent inhibition at 24 hrs. with thiophanate methyl @ 0.1 and 0.2 per cent concentration, respectively. All the tested concentrations of captan and thiram @ 0.1 and 0.2 per cent concentration at 72 hrs. incubation period recorded less than 20 per cent inhibition of T. harzianum. Top |
