Sorry that is not correct. But they have one too; we have never been there though. Below is their claim to fame copied from their web site. 

The World's Largest Pecan is located on U.S. Hwy. 24, 3 miles east of Brunswick, MO, was built by James Pecan Farms Inc. as a replica of their patented Starking Hardy Giant pecan, a large thing-shell variety discovered by George James in 1955. The concrete replica is 7 feet diameter X 12 feet long, and weighs about 12,000 pounds. The James Farms boast a total of 10,000 pecan trees. Brunswick, located on the Missouri River is the finest pecan-growing region in the state.
