Isaac raised havoc with much of the southeast Louisiana agriculture industry.

Many crops will have to be replanted, while some are lost for the season.

Plaquemines Parish citrus fruit took quite a hit.

"The navel had a lot of damage, a lot of fruit dropped. So the navel crop will be reduced," says LSU Ag Center County Agent Alan Vaughn. "We lost about 80 percent of the navel, and only about 20 percent of the satsumas."
 
"The navels dropped, but the satsumas are doing fine," Vaughn says. "The satsuma crop looks pretty good, because navels don't have seeds and seeds are the hormone that makes it stay on the tree a little bit longer...more resistant to rough handling."

The navel harvest that was lost is gone for the season. The trees only bear fruit once a year.

Many River Parish and Northshore crops were just planted prior to Isaac. And flooding in those areas will likely mean shortages in local produce over the next two months.

"They're going to have to replant their fall crops which may have gotten hit in the  storm. And, luckily, it's not too late for that," says Richard McCarthy, director of MarketUmbrella, the organization that helped establish the Crescent City Farmer's Market.

But he says some local produce may be scarce for a while.

"I think it's going to more like November that we see leafy greens, okra and broccoli. This is going to be a lean season," McCarthy says. "For the fall watermelons and for the fall tomatoes, it's going to be tough going."

"I think, come Thanksgiving, we're going to have a lot to be thankful for because the produce will be coming in."

He says the larger impact of Isaac could be whether small farmers in flood-prone areas even choose to return and rebuild.
