Abstract

Chili (Capsicum annuum L.) is a popular commercial crop that is used as both a spice and a medicinal herb. During
the previous years, fungal wilting infections were found very common in Chili, resulting in a global yield loss of about
10-80% in the annual production of chili. Presently, from September to November 2021, a field survey was carried
out to gather diseased samples of chili plants exhibiting wilt symptoms, in several villages specifically 139 6/r, 166
7/r, 138 6/r, and 425 6/r in Tehsil Haroon Abad, situated in the district of Bahawalnagar. The wilting disease was
shown to be present in 55 and 60 percent of C. annuum plants. Fusarium oxysporum was identified as the wilt diseasecausing agent of chili plants through fungal pathogen isolation and morphological identification. Fusarium
pathogenicity was proven in Koch’s pathogenicity trials using the detached leaf method and pot assays. The pathogen
could result in a serious economic impact on the chili crop or might be of other spices and herbs if not managed in
time
