From the Fresno Bee:

San Joaquin Valley farmers, already slammed this year by hail and high fuel costs, could be hit with another blow: a shortage of workers.

Tighter border enforcement, increased smuggling costs for immigrants and drug-related violence are contributing to fewer people coming to the United States from Mexico -- a longtime source of undocumented workers for Valley farmers.

And while critics of illegal immigration may be pleased with the current decline, farmers are worried.

"For now, they are getting the job done," said Barry Bedwell, president of the Fresno-based Grape and Tree Fruit League. "We just don't know what this will be like later this summer."

From mid-June through October, labor-intensive crops, including peaches, plums, nectarines, pluots and grapes, will reach their peak, as will the demand for workers to care for and harvest the fruit.

Fewer workers could mean delays in harvesting, higher labor costs and potentially higher prices at the grocery store.
