Abstract: Trianthemae portulacastrum L. (Family: Aizoaceae), commonly known as horse purslane is a troublesome weed in Indian agriculture. It is known as Hand Qooqi in Arabic, Dewasapt in Persian and Horse purslane in English. A field study was conducted at crop fields of Visakhapatnam district in Andhra Pradesh to screening of agents to control weed population by means of eco-friendly approach i.e., biological control. During field study severe infection on horse purslane was examined and the foliar disease symptoms represented as round to irregular maroon spots with dark borders. The pathogen allied with the infection of horse purslane was isolated from infected parts of the weed and the isolate was confirmed as Gibbago trianthemae Simmons. The disease severity of the isolate was examined by means of invitro study and the results revealed the pathogenicity of the isolate. The findings of research suggested that the isolate, G. trianthemae is highly virulent to host weed and recommended for further studies as an effective biological control agent.
