Norman also encouraged cotton producers to be vigilant in cotton stalk destruction as soon after harvest as possible.

“Boll weevil eradication efforts are ongoing and making progress,” he said. “But, in order for the progress to continue and the program to be successful, cotton stalk regrowth from old stalks or volunteer seedlings must be cleared from all fields by the end of this cotton season.”

He said seedling cotton coming up where other crops are planted in old cotton fields has created problems recently in the Valley and other areas of Texas.

“Now termed non-commercial cotton, cotton plants in fallow land or in other crops have proven to be a serious trouble spot for boll weevil eradication efforts. This year, according to the eradication program in the Valley, one-third of the weevils caught in 2012 came from non-commercial fields.”

He said part of the problem comes from non-commercial fields with volunteer seedlings that are not sprayed because insecticides labeled for use on the primary crop are not available. “The lack of approved labels for some of these crops and the difficulties in locating the cotton growing in the non-commercial crop hamper control measures. The Foundation continues to seek additional labels for weevil control in non-commercial crops.”

He said producers may obtain many herbicide labels for volunteer cotton control in grain crops from the AgriLife Extension Service or by visiting the Texas Boll Weevil Website at txbollweevil.org and clicking on the link on the right side of the web page.

Norman said the current issue of Pest Cast will be the last for this season.
