Impact of Integrated Management Practices on Virus Disease Management in Papaya (Carica papaya l.) at Farmer’s Field Level

Papaya is susceptible to various virus diseases, among these leaf curl and papaya ring spot are major virus diseases in papaya. A total 15 front line demonstrations for virus disease management in papaya were conducted for three years from 2021-2022 to 2023-2024 at farmer’s field, Nellore district of Andhra Pradesh. The higher incidence of papaya ring spot virus disease was observed during 2022-23 (50.2%) followed by 2021-22 (43.6%) in farmer practice over the demonstration. In 2023-2024, recorded low virus incidence in both farmer and demonstration plot because of unfavorable environmental condition to virus vectors population due to the farmers were planted in August first fortnight. At last stage of harvesting i.e. in May the higher virus disease incidence was observed due to farmers are not followed management practices. The yield and fruit quality was increased in demonstration plot than farmer practice because following and timely application of integrated management practice. An average 13.53% yield was increased in demonstration plot over farmers practice. The average cost of production was less in demonstration (Rs.2,61,800/-) over the farmers practice (Rs.2,76,047/-), gross and net returns were high in demonstration than farmers practice. The higher B:C ration was observed in demonstration plot (3.28) and in farmer’s practice it was recorded 2.86. by adopting of demonstration technology the virus diseases were controlled effectively and also yield & gross returns were increased.
