Wheat is a commonly cultivated as staple food crop in Pakistan. It is heavily attacked by
a number of diseases like rusts, smuts, bunts and black chaff, a bacterial diseased caused
by Xanthomonas campestris pv. translucens due to the prevalence of diverse
environmental conditions in different ecological zones of Punjab. Maximum disease was
recoded in semiarid and central districts of Punjab as up to 25%, 23% and 18% in
Layyah, Bhakkar and Okara respectively. Disease was recoded minimum in arid
areas like Attock and Okara as 8% and 6%. four plant extracts, bulb of Allium
sativum, Allium cepa, chilies (Capsicum annum L.), Terminalia chebula and bio-product
Biosal and Vampire were tested for their efficacy in vitro against Xanthomonas
campestris pv. translucens. Biosal and Vampire
showed efficient results to reduce the
pathogen growth on Nutrient Glucose Agar (NGA) medium.
