ABSTRACT.
Fruit production in southern Uruguay takes place mostly in orchards with an average area of 7 ha and creates a diverse landscape due to multispecies planting. Since the 1990s, researchers have been addressing the control of major pests in deciduous fruit production within Integrated Pest Management (IPM) guidelines. The mating disruption (MD) method has been relatively successful against both the codling moth (Cydia pomonella - CM) and the oriental fruit moth (Grapholita molesta - OFM) at the farm level. To improve results, an area-wide approach was initiated and, with the participation of the agricultural cooperative JUMECAL, a local plan was implemented covering up to 300 ha during the 2012 growing season. That year, a program to cover over 2100 ha was designed. After two more seasons of successful control, and with increasing grower participation aiming for full coverage to include all neighboring orchards, the program presently includes 3563 ha, nearly 85% of the commercial production area. The system involves 360 growers, and almost 70 scouts that assess damage in the field, follow the insect populations through pheromone traps, and register pesticide applications. Our results show that over 95% of the area counts less than 0.5% of the damage from lepidopteran pests (CM, OFM and two South American leaf rollers) and a reduction of insecticide use. Many growers even obtain very good results with only one insecticide spray. These changes bring about new balances within the fruit production system, with some secondary pests decreasing while the economic importance of others increases. This has set new challenges for managing certain pests and developing alternative tactics to replace conventional insecticides. Current results, changes in the program design and future projections are presented and discussed.

ABSTRACT.
Pear is a temperate crop, which grows in mild winter regions, and may present several development anomalies, which can negatively affect yield and fruit quality. To overcome these obstacles and achieve economically satisfactory yields, the use of bud break promoters has shown promising results. The most used promoters are hydrogen cyanamide (HC), mineral oil (MO) and Erger®. The present study aimed to evaluate the effectiveness of HC, MO and Erger® following different chilling hour accumulation on bud break of 'Hosui' pear. 'Hosui' pear shoots were collected with 103 chill hours (CH) and conditioned in cold storage at 4±1°C for 0, 6, 12, 18, 24 and 30 days. For each date, shoots were cut as single bud cuttings, where the following treatments were applied in four replications of ten cuttings: control (water), HC 1%, MO 5%, Erger® 3% + calcium nitrate 3%, and HC 0.5% + OM 3%. After these, they were forced in a growth chamber until bud break, which was assessed every two days to estimate the bud break percentage and average bud break time. Bud break percentage showed no difference between treatments when submitted to 0 and 6 days (247 CH) of cold storage. After 12 days (391 CH), HC and HC + MO increase bud break percentage compared to the control. Those exposed to 18 days (535 CH) and treated with HC and HC + MO showed no significant difference in the bud break percentage compared to the control, whereas Erger® and MO significantly decreased the bud break percentage compared to other treatments. The average bud break time of HC treated cuttings was advanced the most and control delayed the most. When cuttings were subjected to low chilling hour accumulation, HC and HC + MO were more effective in bud break compared to Erger® and the control, while with higher chilling hour accumulation, the bud break promoters were dispensable.
