From whiteflies in southern Georgia to bollworms in North Carolina to plant bugs in Virginia, 2016 was a challenging insect year for cotton growers across the Southeast. Dominic Reisig is urging farmers to be prepared for another challenging year.

Reisig, North Carolina State University Extension entomologist, addressed “Emerging Insect Issues in the Southeast” at the annual meeting of the Southern Cotton Growers and Southeastern Cotton Ginners in Charlotte, N.C., Jan. 20, where he provided an insect situation, outlook report and control recommendations.

Black flag in Virginia cotton fields

As you may have heard, reports out of northeastern North Carolina are talking about infestations of plant bugs (Lygus) causing a symptom called “black flag” by feeding on presquare cotton.  This is very rare in US cotton.  This symptom is termed “black flag” due to the death and blackened appearance of the expanding terminal leaves.  The danger is creating “crazy cotton”, which is loss of apical dominance, causing multiple terminals per plant, delayed squaring, or yield loss.  Terminals can be destroyed from only 20 minutes of feeding.

Managing plant bugs requires a combination of IPM tools

In Delta Farm Press

Plant bugs have become “a nightmare to control” in much of the Delta, says Jeff Gore, and to contend with the problem growers need to rotate chemistries, shorten application intervals, plant as early as conditions allow, and consider planting hairy leaf cotton varieties.

The most significant insect event in the past week was the report of plant bug tolerance to all labeled or recommended insecticides in the Tennessee Valley of Northern Alabama. Several of our most experienced consultants are reporting that all classes of chemistry are suppressing plant bugs but their presence and damage behind applications are still above threshold levels.

Timing continues to be a key ingredient in cotton insect control

From Delta Farm Press

For years, the boll weevil was public enemy No. 1 for Tennessee cotton farmers. The boll weevil is gone thanks to the hard work of cotton growers and research scientists. But the malathion sprays that took out the boll weevil and plant bugs are gone as well, creating an environment where plant bugs have become a major problem. The University of Tennessee’s Sandy Steckel talked about the current efforts to control the latter during a stop on the Cotton Tour at the West Tennessee Research and Education Center.

Consultant survey paints North Carolina’s 2013 cotton insect picture

From Southeast Farm Press

By Jack Bacheler, North Carolina Extension Entomologist

Information from North Carolina’s licensed independent crop consultants is invaluable in determining cotton pest status and insecticide inputs from region to region and from one year to the next.

Their responses to our survey questionnaire are both an accurate account of the past “insect year” and represent approximately one third of North Carolina’s total cotton acreage.

Insect Control focus in late cotton in Mid-South

In Delta Farm Press

The 2013 Mid-South cotton crop is late.

July 4 in the Mid-South is traditionally a time when yellow blooms formally announce the up and coming cotton crop. For this season however, Independence Day blooms were few and far between, signaling both the lateness of the crop and a big shift from cotton to grain this spring.

After a prolonged period of wet weather, North Carolina cotton is benefitting from some sunny, hot weather.

But in most areas of the state, the crop has some catching up to do. In some cases, the crop may never manage this.
