During survey, cowpea [Vigna anguiculata (L) Walp.] was found severely affected by ascochyta blight and disease was found well distributed in the surveyed areas of Meghalaya. The per cent disease incidence was found maximum in Mawlai (52.34%) under East Khasi Hills followed by RRTC (45.57%) under Ri-Bhoi district. In average, PDI was found highest in Ri-Bhoi district (37.50%) and least in West Khasi Hills district (15.47%). Ascochyta phaseolorum was consistently isolated from symptomatic leaves. Plant extracts and fungicides were evaluated in vitro against the growth of the pathogen.Among the fungicides, propiconazole and carbendazim at 0.1 and mancozeb at 0.2 per cent concentrations gave 100% inhibition of mycelial growth. Among the plant extracts, garlic extract at 5% showed the highest per cent inhibition (86.91±1.07%) of mycelial growth followed by turkey berry at 15% (82.33±0.44%). These could be further evaluated under in vivo condition to confirm its efficacy and could be included as components for integrated disease management for ascochyta blight.
