PEREZ BARRAZA, Maria Hilda et al. Effect of pruning on white mango scale and production of mango ‘Ataulfo’. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.8, pp.1841-1853. ISSN 2007-0934.

The high bearing and closed crowns in fruit create favorable conditions for the development of pests, yield reduction and hinder management practices. Tree growth can be controlled through pruning, which favors light penetration, high productivity and fruit quality. The objective was to determine the effect of different types and intensity of pruning, alone or combined with detergent, on white mango scale populations, production and fruit quality of mango ‘Ataulfo’. The study was conducted during 20122013 and 2013-2014 in orchards from the municipality of Tepic, Nayarit. Two experiments were established: one to determine the effect of pruning intensity (0, 50 and 75 cm trimming) and others types of pruning (no pruning, cube and pine), with or without detergent application under a completely random design with factorial arragement (3*2). The intensity and types of pruning decreased flowering 15- 20% in the immediate year to prunning, but in the second year it increased in pruned trees. On the second year, trees with light and severe pruning increased yield in 26 and 20%, respectively, compared to controls; with cube and pine pruning the increase was 14% and 21%, respectively. Pruned trees produced fruits of greater weight and had no damage by scale, while no pruning trees and without detergent had low damage by scale. Pruning and application of detergent in mango trees keeps low white mango scale populations in the months of highest incidence.
