Daniel interviewed Tom Turini, UC Cooperative Extension advisor in Fresno County. He said it's common to find some tomatoes infected with curly top, but this year is much worse than usual. The virus is transmitted by beet leafhoppers, which in dry years arrive early from coastal foothills and infect a bigger swath of cropland.
Fresno county has about 100,000 acres of processing tomatoes. Some fields have been completely lost.
"It is likely we're going have lower production in this area, which does account for over a third of California processing tomato production," Turini said.
