Abstract: The present investigation was conducted in order to manage the mangu mite in Sweet Orange in Nalgonda district of Telangana. In India, Telangana is one of the major sweet orange producing states. Sweet Orange is major important horticulture crop which was having high source of vitamin C. Farmers are getting lower yields due to non adoption of proper management practices for mangu mite hence decrease in the quality of fruit so that farmers getting less price to their produce. In order to reduce mangu mite infestation and improve yield and quality of fruit, OFT was conducted in farmers’ field in two years with three locations in each year. Proper management practices for control of mangu mite in Sweet Orange improve the yields and B:C ratio in OFT, when compared to farmer practice. The average yield and B:C ratio of three farmers in 2016-17 was 7300 kg/ac and 1.7:1 in farmer practice, where as in OFT average yield and B:C ratio was improved to 8900 kg/ac and 2.3:1 respectively. In 2017-18 average yield and B:C ratio was 9120 kg/ac and 5.4:1 in OFT compared to farmer practice was 7840 kg/ac and 4.08:1 yield and B:C ratio respectively. Proper management practices with application of insecticide to mangu mite reduces the loses and increase the yield and quality of fruit.
