Pest management record-keeping duties shift with computerization
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
