Abstract

                                Papaya Ring Spot Virus (PRSV) is one of the major obstacles for boosting papaya production in the country. There is no curative control measure available through conventional methods. Precautionary measures for PRSV incidence viz. rouging, cross protection, vector controls separately are not much effective. Hence an integrated management strategy involving raising of papaya seedlings under Nylon net (40-60 mesh) and spraying of acephate 1.5g/litre, 3 days before planting. Use of two rows of border crop viz. maize (sown 15 days before planting)+. Spraying of urea @ 10g/liter + zinc sulphate @1.5g + boron @ 1.0g per litre recorded reduced PRSV incidence of 42.7 % with maximum average yield of 49.68 kg/tree compared to control with maximum PRSV incidence of 95.6 % incidence with reduced yield of 23.76 kg/tree at 150 days after planting.
