Post-emergence herbicides are cost effective for vineyard floor management on the Central Coast.

摘要

Central Coast growers in California (USA) are under increasing scrutiny and regulatory pressure to manage herbicide use because of their farmland's proximity to the Monterey Bay and National Marine Sanctuary. Vineyard floor management practices typically consist of a combination of weed control strategies, including herbicide use and cover crops. A total of 9 combinations of vineyard floor management practices were evaluated for their impacts on fruit yield, quality and costs in grapes. It was found that compared to the grower standard, post-emergence herbicide treatments generally used smaller amounts of chemicals and were less costly, with similar yields and quality.
