          Abstract

          The objetive of this study was to evaluate the effect of Retain® in combination with other chemicals used in orchard management of apple trees, on maturation and pre-harvest drop of ‘Imperial Gala’ apples. During the 2006/07 and 2007/08 growing seasons, seven days before the predicted harvest date, the following treatments were applied: 1)
          check; 2) Retain® 800g/ha; 3) Retain® 800g/ha + Captan 500PM 4,000g/ha; 4) Retain® 800g/ha + Cercobin 700WP 1,500g/ha; 5) Retain® 800g/ha + Sumithion 500CE 1,500ml/ha; 6) Retain® 800g/ha + calcium chloride 6,000g/ha. None of the treatments evaluated showed symptoms of phytotoxicity. Retain®, when applied in combination with some chemicals used in orchard management of apple trees, showed similar performance both in maturation and in pre-harvest fruit
          drop control of ‘Imperial Gala’ apples in relation to the isolated Retain® application, especially for shorter periods than 23 days after harvest.
