Gallo’s Sonoma Vineyards

Gallo has a long history of IPM practices in the California winegrape industry, and Gallo’s seven vineyards in Sonoma County exemplify this leadership. Gallo strives to stay on the cutting edge of environmental sustainability practices by minimizing pesticide use and exceeding application requirements to protect worker safety.

Gallo is continuously reassessing its pest management practices to reduce pesticide use, runoff and environmental effects. For example, Gallo has converted to double-row spray rigs to reduce to a single pass of herbicide in the vineyard. The company provides funding and support for pocket gopher studies on its Laguna Ranch.

Other examples include using falcons for starling prevention, and integrated Pierce’s disease management and removal plans. Prevention practices include installation of owl boxes and raptor perches for rodent control, and the release of predacious mites.

Marin County Integrated Pest Management Program

Marin County adopted an IPM policy in 1983, followed in 1998 with an IPM ordinance establishing an IPM Commission and IPM coordinator and a requirement that all county departments comply with IPM standards. This strong commitment has helped reduce pesticide use on Marin County owned, managed or leased property by 90 percent in the last 10 years.

The IPM program uses a wide range of practices to reduce pesticide use,

including: beneficial insects; owl boxes and traps for rodent control; honey to attract skunks to dig up yellow jacket nests; coyote replicas to scare off geese; volunteers to hand weed and mulch for weed control; and replacement of landscape plants that attract pests with drought tolerant, native plants. The program also conducts flame trials for weed management and applies mint oil, clove oil and other least-toxic products when pesticides are needed.

The program maintains a comprehensive website with detailed records of all IPM activities, including both chemical and non-chemical management, and a list of allowed pesticides.
