The LSU AgCenter estimates Hurricane Isaac has cut Louisiana's pecan harvest by 15 percent.
Charlie Graham, professor for fruit and nut crops, says that would bring the total to just over 11 million pounds — down from pre-storm estimates of 13 million to 13.5 million pounds. It still would be up from last year's 9 million pounds.
Graham says prices are likely to be similar to 2011 levels.
Last November, farm prices ran from $1.25 to $3.50 a pound, with most varieties starting above $2.
