ABSTRACT.
The spread of the epiphytic population of Xanthomonas campestris pv. vesicatoria and the disease it causes, bacterial leaf spot, were studied in field plots of pepper near Gainesville, Florida. In the summer of 1989, the epiphytic population of X. campestris pv. vesicatoria was dispersed to the west-northwest from point sources of diseased plants. Winds from the southeast during rainstorms were essential for the spread of bacteria in the field. In the autumn of 1989, a focus of bacterial leaf spot developed naturally near the centre of the experimental plot. The epiphytic population of X. campestris pv. vesicatoria increased sharply after a 2-day rain accompanied with strong wind. The wind was believed to be responsible for the transport of bacteria to distances 32 m from the focus. Initially in both seasons, the epiphytic populations occurred as distinct gradients from the focal sources of diseased plants. These gradients flattened over time and the disease incidence increased to near 100%. The increase in the epiphytic populations of the pathogen to > 3.0 log10 (cfu cm-2) on healthy plants away from the foci preceded disease appearance by several weeks. Applications of cupric hydroxide plus mancozeb significantly reduced the epiphytic population of X. campestris pv. vesicatoria on pepper leaves and slowed the spread of disease in the plots. |

ABSTRACT.- Technology development and innovation are fundamentally different from scientific research. However, in many circumstances, they are evaluated jointly and by the same processes. In these cases, peer review -the most usual procedure for evaluating research - is also applied to the evaluation of technological products and innovation activities. This can lead to unfair results and end up discouraging the involvement of researchers in these fields. This paper analyzes the evaluation processes in Uruguay's National System of Researchers. In this system, all members' activities, both scientific and technological, are evaluated by peer committees. Based on documentary analysis and semi-structured interviews, the difficulties faced by evaluators in assessing technology products are explored. The article highlights the persistence of a linear conception of the link between science and technology and describes the obstacles to assimilate the particularities of technological activities. Refereed publications are presented as the only uncontested product. Other types of output are reviewed with suspicion. This study emphasizes the need for specific mechanisms to evaluate technological production within academic careers.
