    Pest management record-keeping duties shift with computerization

    No full text
    Computer software has been widely adopted in the tomato processing industry for maintaining pest management records. Although computers have not reduced the time necessary to complete record-keeping requirements, they have shifted some of the burden from growers to pest control advisers (PCAs). Most records kept are pesticide use records required by law or by processors, and the legally required written recommendation. There is little evidence that computer software is being used to maintain or analyze field scouting data

    Long-term studies find benefits, challenges in alternative rice straw management

    California state legislation passed in 1991 mandated a phased reduction of rice straw burning in the Central Valley, to reduce air pollution. In 1993, UC Davis scientists launched an 8-year research project on the long-term effects of various alternative means of managing rice straw. Burning, incorporation into the soil, rolling, and baling and removing the straw were compared, with and without winter flooding. None of the various practices reduced grain yields on our experimental plots, but there was an increase in weeds when straw was incorporated, and in particular when the fields were not winter flooded. However, when straw is incorporated, nutrients are returned to the soil and less nitrogen fertilizer can be applied, resulting in lower production costs and less potential for water pollution. In addition, waterfowl on the Pacific Flyway benefit significantly from the wetlands created when fields are flooded during the winter
