Caltrans Roadside research studies invasive and noxious species to prevent and control their spread within the highway right-of-way
Invasive and noxious weed species are studied to prevent and control their spread within the highway right-of-way.
This field trial research project studies the performance of a permanent vegetation control product (weed mat). Potential benefits of this field trial include improved weed control, reduced herbicide use and reduced potential of herbicides in storm water runoff.
This study evaluates several established sequences to determine effective ways to convert existing annual non-native vegetation to native perennial species.
The use of synthetic herbicides on Caltrans managed acreage has raised concerns over environmental quality, public health, and worker safety, especially in the North Coast area of California. Alternative methods of vegetation control were studied to determine their efficacy and economic feasibility.
This report documents the status of the development of biological control agents for Cape ivy. Research of promising insects and pathogens has demonstrated reduction in biomass and structure of Cape ivy plants.
This is the final report on work carried out for the biological control of French broom in California by Commonwealth Scientific and Industrial Research Organization at it European Laboratory in France in collaboration with the USDA European Biological Control Laboratory.
This report summarizes the research during the calendar years 1999 and 2000 that was directed by Research Entomologist, Joseph Balciunas, at the USDA-ARS Exotic & Invasive Weed Research Unit in Albany, California. The primary project during this period was Yellow Star thistle.
This report documents the integrated pest management program for control of the Eucalyptus Longhorn Borer. The basic biology of the insect and silvicultural practices are critical for limiting risk of infestations. Site conditions and tree maintenance are important contributors to species susceptibility or resistance. The introduction and establishment of parasitic wasps offers a cost effective, safe and permanent reduction in beetle populations.
