Chemical control of cowpea anthracnose caused by (Colletotrichum lindemuthianum)

Abstract

The pulse crop is very much known as poor man’s meat. One such crop is cowpea which has all the nutritional requirements that meets the demand of poverty trodden people. But, its bumper production is significantly hampered due to the anthracnose disease caused by Colletotrichum lindemuthianum. Prior to application of fungicides in the crop for the management of pathogen, tests were conducted by taking 13 different contact and systemic fungicides to find out their effectiveness in controlling the growth of mycelium of the test fungus in five different concentrations i.e. 0.05, 0.10, 0.15, 0.20, 0.25 and 0.30%. Difenoconazole proved to be fatal against the mycelial growth of the pathogen at 0.10% while other fungicides such as Thiophanate methyl at 0.15% followed by copper hydroxide, carbendazim and penconazole proved their efficacy at 0.25% but others influenced least.
