Abstract:
Citrus is the most extensively produced tree fruit crop in the world. Citrus sp. are susceptible to a number of destructive diseases that are continuously emerging and which can severely limit production or totally decimate the industries of the country. Among these citrus canker is one of the most important biotic constraints in the country. The present study was undertaken to find the best and most economical agrochemical in managing this disease. The study of two year trial suggested that four aerial sprays of streptomycin sulphate 90% + tetracycline hydrochloride 10% and copper oxychloride 50 WP or Bordeaux mixture 1% (Tank mixed) started first at initiation of disease and subsequent three sprays at 20 days interval for effective and economical management of bacterial canker in citrus with quality fruit yield.
