La Organización Internacional para la Lucha Biológica (OILB) define a la Producción Integrada como ?Un sistema de explotación agraria que produce alimentos y otros productos de calidad mediante el uso de recursos naturales y de mecanismos reguladores, para reemplazar los insumos contaminantes y para asegurar una producción sostenible?. En consecuencia, este enfoque concierne a la calidad de los productos agrícolas, especialmente en relación a su impacto ambiental, sobre la salud de los trabajadores rurales y consumidores.

ABSTRACT. Browning of the lettuce stem butt is one of the main postharvest changes induced by wounding during harvest. The browning process of the harvested lettuce starts with yellowing, then becomes reddish brown, and finishes with an intense brown pigmentation (Tomás-Barberán et al., 1997). Castañer et al. (1996) reported promising results to prevent butt discoloration of iceberg lettuce with solutions of acetic acid (10 ml/L and 50 ml/L), and vinegar.

The claim that organic agriculture produces higher levels of phytochemicals has been controversial for decades. Using strawberries as a model crop in field conditions, a preharvest leaf wounding stress was applied to study the production of phytochemicals in fruits. As a result phenolic compounds (PCs) and total soluble sugars increased significantly, where specific phenylpropanoids showed increment up to 137% and several genes related to PCs biosynthesis and sugar transport were overexpressed.

ABSTRACT. Olive scab caused by Venturia oleaginea is one of the most important diseases of olive worldwide. The fungus infects young leaves and fruits by asexually produced conidia. The sexual stage and its importance in the epidemiology and genetics of the pathogen population is unknown. A collection of 52 fungal isolates was obtained from scabbed leaves collected in 16 orchards from three major regions in Uruguay. All isolates were identified as V. oleaginea by PCR with specific primers and sequence analysis of the TEF-1α gene region.

ABSTRACT. Worldwide olive industry has expanded into new climatic regions outside the Mediterranean basin due to an increase in extra virgin olive oil demand posing new challenges. This is the case of Uruguay, South America, where the olive crop area reached 10,000 hectares in the last 15 years and is intended to the production of EVOO. Uruguay has a temperate humid climate with mean precipitations above 1,100 mm per year but unequally distributed, mild winters, and warm summers, with mean annual temperatures of 17.7°C.

ABSTRACT. Field studies were conducted to evaluate new kairomone blends in combination with pear ester (E,Z)-2,4-ethyl decadienoate (PE) and acetic acid (AA) for their attraction of male and female codling moth, Cydia pomonella (L.), in apple, Malus domestica Borkhausen. The addition of decanal to either AA or PE alone significantly increased total and female moth catches. However, the addition of decanal did not improve the attraction of PE + AA.
