Investigations on annual spreading of viruses infecting cucurbit crops in Uttar Pradesh State, India

Abstract During 2018 an intensive study was conducted to determine the viruses associated with cucurbitaceous crops in nine agroclimatic zones of the state of Uttar Pradesh, India. Total of 563 samples collected and analysed across 14 different cucurbitaceous crops. The results showed the dominance...

Total of 563 samples collected and analysed across 14 different cucurbitaceous crops.

Nearly 65% of samples were co-infected with more than one virus. Additionally, host range expansion of CMV, CGMMV and polerovirus was also observed on cucurbit crops.
