Mike Strain says that last year, the program monitored all 229,869 acres of cotton produced in Louisiana and found only 302 boll weevils. That compares to more than 14,700 trapped in 2008.
Strain says fields along the Red River were already free of boll weevils in 2009. He says 99,865 acres in northeast Louisiana were treated for boll weevils last year, with a 98% reduction in numbers.
About $167 million has been spent on the program since 1997. Strain says that over the same time, Louisiana's cotton production rose from 605 pounds per acre to 1,137 pounds per acre.
