Abstract:
Southern corn leaf blight is one of the most serious disease-causing damage in entire country, the disease caused by Helminthosporium maydis by producing lengthy, cigar structured ovoid and greyish lesions on lower leaf parts. This article revealed that both in in vivo and in vitro Propiconazole proved trusty one against pathogen followed by Mancozeb, Carbendazim, Chlorothalonil and COC when compare to control. Also studied the efficiency of Bio-control agents and Botanicals in disease management, Garlic clove extract was proved best one against the Helminthosporium maydis and bio control agents like Trichoderma spp. Very efficient one in controlling the pathogen, bio control agents use antibiosis, enzyme production and mycoparasitism mechanism for inhibiting the growth of fungus, biocontrol agent’s efficacy could exist for one month. Trichoderma isolates will induce resistance in plants against fungal pathogens.
