Abstract:
Anthracnose of bean (Phaseolus vulgaris L.) caused be Colletotrichum lindemuthianum. The major constraints in its low productivity are fungal and viral disease. The pathogen was tested with four fungicides and three bio-agents In-vitro and In-vivo condition three fungicides and two bio-agents were tested in the year 2021-22 and 2022-23. The tested fungicide and bio-agent namely, Carbendazim, Sulphur, Mancozeb, Chlorothalonil and Bio-agent T. harzianum, T. viride and P. fluorescens. Among the tested fungicide Carbendazim was most effective fungicide which showed (3.13 mm) average fungal growth and 96.80 percent inhibition over control. The bio-agent P. fluorescens was least effective which showed (15.63 mm) average fungal growth with 84.05 percent inhibition over control. In-vivo condition Chlorothalonil was most effective fungicide which showed the minimum mean diseases incidence (8.09) percent and maximum yield (95.47 q/ha.) respectively. The bio-agent T. harzianum was least effective which was showed the maximum mean disease incidence (32.33) percent and minimum mean yield was (58.91 q/ha.).
