Susan Stout • Contributing Writer


Ag Unlimited Lyman Logo Color (2)Ag Unlimited/The Lyman Group, a North Coast California agribusiness company, is “working closely with Lake County growers and hopefully helping to maximize production,” says Lake County location manager Bill Oldham.

Ag Unlimited is one of the Lake County Winegrape Commission’s Affiliate Sponsors. Oldham, a grape and pear grower in Upper Lake, is one of Ag Unlimited’s pest control advisers and certified crop advisers. He oversees the company’s North Coast locations for inventory, products, and consulting services.

“Our staff and products aim to help growers solve problems,” said Oldham, who grew up in Upper Lake and has strong ties to the agriculture community. Oldham and Devin Gordon teamed up as consultants in 1988 to start Ag Unlimited and grew the business, adding organic materials and bringing in partner Mike Boer in the 1990s. The firm was purchased and became part of The Lyman Group Division in 2008 and is a member of Independent Agribusiness Professionals.

Consulting services include pest control and fertility advising, scouting services, soil and tissue sampling, and weather monitoring for frost, powdery mildew pressure and soil moisture. “We work toward maximizing the quality of the growers’ fruit, as well as maximizing yields.”

The Lake County facility at 3530 Finley East Road, Finley, is one of four retail warehouse locations. Others are located in Mendocino, Napa, and Sonoma counties. The firm’s stores are in Ukiah, Geyserville, and Sonoma. “We provide services and support to the entire North Coast with some accounts in the Sacramento Valley,” says Oldham. Ag Unlimited serves both organic and non-organic growers with crops ranging from grains and legumes to row crops, vegetables, orchards, and premium winegrape vineyards.

To assist growers, Ag Unlimited supplies fertilizers, foliar nutrients, herbicides, fungicides, insecticides, bulk soil amendments, adjuvants and surfactants, plus an organic line and biodynamic approved product lines. Growers also may purchase weather-monitoring stations.

Ag Unlimited takes pride in providing a dedicated staff of “experienced and respected agricultural consultants and support personnel whose goal is to provide services and products to enable our customers to meet their production goals.”

Oldham became a pest control adviser in 1983 and holds degrees from UC Davis including a bachelor’s degree in entomology and a master’s degree in plant protection and pest management.

Joining Oldham and Boer on the local staff are pest control and certified crop advisers Marc Hooper, Nick Lupien, and Jeff Gleaves. Additionally, Laurie Fullerton is the office manager, John Traphagen is operations manager, Scott Rupert is warehouse assistant, and Alan Bibee works as the facility’s driver.
