Annual percentages of Beltwide yield losses to nematodes have been recorded since the 1952 crop. These records were provided by Dr. Don Blasingame, Coordinator for the Beltwide Nematode Survey and Education Program, and Chairman of the Cotton Disease Loss Estimate Committee.
The following observations are based on the data in the percent loss table:
- The highest yield loss to nematode damage was 5.32% in 2006.
- The lowest yield loss to nematode damage was 0.91% in 1958.
- The Beltwide average annual yield loss for the 50-year period is 2.47%.
- The most dramatic 25-year increase in Beltwide yield losses was from 1.00% in 1987 to 5.32% in 2006.
