In vitro evaluation of the test fungicides against C. gloeosporioides inciting anthracnose of cowpea revealed that propiconazole (0.1%), flusilazole (0.1%), tebuconazole (0.1%) and carboxin + thiram (0.4%) caused 100% inhibition of the mycelial growth of the pathogen. The in vivo evaluation showed that three rounds of foliar application of flusilazole (0.1%) at 30, 45 and 60 days after seed emergence recorded the lowest disease index (5.60) followed by tebuconazole at 0.1% (8.30). The field evaluation revealed that foliar application of flusilazole or tebuconazole at 0.1% recorded the lowest anthracnose (0.93) index followed by treatment with copper oxychloride (0.2%). The persistence and degradation of fungicide residues indicated that tebuconazole (0.1%) had the shortest waiting period (zero day), indicating its safety to the vegetable.
