Ecofriendly management of papaya ringspot disease

Atheena Harish, K. Anita Cherian

Abstract


Papaya plants are prone to several viral diseases. During the last decade, the incidence of papaya ringspot disease caused by Papaya ringspot virus (PRSV) has become a major threat to profitable cultivation of papaya across Kerala. A pot culture experiment was carried out to develop a recommendation for the management of papaya ringspot disease using different defense inducers, micronutrients, plant products and microbial formulations. Among the various treatments evaluated, foliar spraying and drenching of leaf extract of Bougainvillea spectabilis (10%) recorded lowest disease severity of 6.67 per cent followed by Pseudomonas fluorescens (2%) with a disease severity of 11.11 per cent. The leaf samples collected after the final application of these two treatments recorded a significant reduction in the concentration of virus also. Both the treatments were found to be superior in terms of plant height and girth. In addition, assessment of chlorophyll content of leaves revealed that B. spectabilis treatment was superior with the highest chlorophyll content (44.67 SPAD units). The present study revealed that foliar application as well as drenching of leaf extract of Bougainvillea spectabilis (10%) and Pseudomonas fluorescens (2%) reduced the severity of papaya ringspot disease.
