dc.description.abstractThe objective of this study was to evaluate different citrus leprosis management tactics during seven seasons, based in pruning and acaricide applications, considering technical and economic aspects of each tactic. The trial was conducted from October 2003 to August 2010 in an orange plantation of Pera cv. located in the municipality of Reginópolis-SP, Brazil. The plants of citrus used were12 years old and grafted onto Cleopatra tangerine. The experimental design used was randomized blocks, in a factorial scheme, made up of factors type of pruning (A), with six levels: (1) drastic pruning, (2) intermediate pruning without leprosis lesions, (3) intermediate pruning with leprosis lesions (4) light pruning, (5) without pruning and (6) replant; acaricide applications factor (B), with three levels: (1) without acaricides applications, (2) with lime sulfur applications and (3) spirodiclofen or cyhexatin applied in rotation; pruning factor to remove leprosis symptomatic branches (C), with two levels: (1) with pruning for removal, (2) without removal pruning. The combination of factors, with respective levels (6 x 3 x 2), resulted in 36 treatments that were repeated four times, with each parcel being made up of three plants in a row. After seven years, it was observed that the types of the pruning and remove of leprosis symptomatic branches used as single management tactic, is not sufficient to leprosis control. Therefore, the results demonstrated that for leprosis management, it is essential the association between tactics, especially the control mite vector. For ensuring the citrus production economically, the use of acaricides highly efficient is essential in B. phoenicis control. The recommendation of the type of pruning should be in function of the leprosis incidence and severity in the orchard. In orchards with low leprosis incidence and severity the light pruning is more appropriate, because it is efficient and ensures greater financial balance. However, in orchards with high leprosis incidence and severity it is indicated the severe pruning for reducing or eliminating inoculum source. Between the severe prunings, the intermediate pruning with leprosis lesions is the most relevant, because the financial return will be faster. Replant is indicated only for young orchards, because does not imply in changes onto cultural practices.en
