Abstract:

Weeds are considered as a source of new viruses and reservoirs of unidentified economically important viruses but are often neglected during diversity studies. Here, the weeds which are highly susceptible for the virus infection found in the Pulse Research block of Tamil Nadu Agricultural University, Coimbatore is documented. Many scientific reports have demonstrated that weeds serve as reservoir or alternative hosts for begomovirus survival and spread in the absence of the main crops. Now some new weeds are also added to the list in transmitting virus and host for vector. Weeds which continuously acts as a carrier of virus particles over season is observed and this was documented. Euphorbia geniculata was observed with similar symptom as developed by the Black gram and Green gram Yellow Mosaic virus. Already for powdery mildew this weed is the host and now this is observed with sterility symptoms similar to Yellow Mosaic Virus.  The fruiting bodies are turning in to a claw like structure with severe malformation depicting the same in blackgram and Euphorbia geniculata. The most hardy Pathenium hysterophorus also reported with sterility symptom due to virus infection. Phyllanthus niruri, Croton sparsiflorus also observed with sterility symptoms. Cleome viscosa is observed with severe sterility similar to phyllody in the Research block and as well as all the parts of Tamil Nadu and this is commonly occurring even in roadsides expressed with partial and complete sterility and spreads in North and South Tamil Nadu. Hence these weeds should be watched for virus transmission to the crops as they persist over generation and their transmission by seeds also to be verified. Plant Pathologist should detail the flow of virus between weeds and crops since, the hardy weeds are also expressing with severe sterility symptoms in field condition.
