Galpin Family Farms, in California's Central Valley, is a second generation farm run by Lisa and Anthony Galpin.  Specializing in stone fruit, which is grown mostly for farmers markets, their family has been growing as sustainably and pesticide free as possible since the late 70s. They mostly use integrated pest management, but will (rarely) use OMRI approved sprays for pest management if no alternatives exist.  They do not use toxic herbicides, but rather use alternate approaches such as hand weeding.
