Best Management Practices for Tarnished Plant Bug

👤Jeff Gore, Research and Extension Entomologist 🕔17:50, 5.Mar 2015

The tarnished plant bug is the most important insect pest of cotton in the Mississippi Delta. Management with insecticides has become difficult in recent years and more tools are needed to economically manage this pest. Although it is early March and we are getting pair of unusual winter storms in the Delta, it is not too early to start making a plan for managing tarnished plant bugs in cotton. We have done a lot of research over the last several years with the goal of making tarnished plant bug management more economical for producers without sacrificing yield. See the attached document for more details on the best management practices listed below.

Management Guidelines for Sugarcane Aphids in MS Grain Sorghum 2015

👤Angus Catchot, Extension Entomologist 🕔16:42, 24.Feb 2015

In 2014 a new pest of MS grain sorghum, Sugarcane aphid, made a dramatic entry infesting every county that grew the crop. This pest originally showed up in grain sorghum in Texas and Louisiana in 2013 with a single find very late in the season in Bolivar County, MS. By the end of 2014, this pest quickly spread throughout the entire southeast.

Do Neonicotinoid Seed Treatments Have Value Regionally in Soybeans?

👤Angus Catchot, Extension Entomologist 🕔14:34, 31.Oct 2014

There has been a tremendous amount of scrutiny put on the neonicotinoid class of chemistry in recent years because of the potential link to declines in bee numbers. Researchers are working feverishly across the nation and the globe to determine the exact causes of bee decline. No doubt pesticides can and likely play a role to some degree, but there are many factors that also influence bee health such as habitat loss, Varroa mites, and diseases.

Not all Boll Rots are caused by Bacterial Blight

👤Tom Allen, Extension Plant Pathologist 🕔06:42, 31.Oct 2014

Boll rot appeared to be a common occurrence in numerous cotton fields at the end of the 2014 season. However, not all boll rot can be attributed to bacterial blight, especially in situations where the disease was not observed prior to harvest. Secondary fungal infection can ultimately obscure the observable boll symptoms associated with bacterial blight. Keep this in mind when scouting fields at the end of the season as bacterial blight boll lesions can oftentimes be obscured by secondary fungal invaders.

Soybean Loopers Showing up in Late Soybeans:

👤Angus Catchot, Extension Entomologist 🕔14:34, 5.Sep 2014

Soybean loopers are starting to show up in high numbers in many areas of the state. In many cases, soybeans are past the point where yield loss can occur, but there are many later planted soybeans that need to be protected for a while longer. Below are a few tips on when to treat and what to treat with.

Terminating Insect Sprays in Mississippi Soybeans

👤Angus Catchot, Extension Entomologist 🕔11:56, 15.Aug 2014

We are quickly approaching that time of year where some of the earlier planted fields are turning color and others are approaching R6 vey quickly. Often times many of the insect pest we deal with “pile in” about this time and growers face the tough decision to treat when it may not pay back or try and race them to the end. We have devoted a lot of time and effort in recent years to evaluate and validate thresholds in soybeans under the current growing practices in Mississippi. Through these research efforts we have made several changes to insect thresholds and termination points for insect pest of soybeans in MS.

Bollworms in Dual Gene Bt Cotton: Control and Expectations

👤Angus Catchot, Extension Entomologist 🕔07:29, 15.Aug 2014

Over the last 7 days we have had numerous reports of high bollworm numbers in some BollGard II, TwinLink, and WideStrike fields in the Mississippi Delta. We have seen fields in the past that reach treatable levels but some reports are much higher than we have seen in recent years. At this time there does not appear to be any specific varieties that are adversely affected more than others. It appears to be a function of high pressure in isolated areas at this time.

White Sugarcane Aphid: A Potentially Devastating Pest of Grain Sorghum

In 2013 a new aphid pest called the White Sugarcane Aphid, Melanaphis sacchari, was detected in grain sorghum in 38 counties in Texas, Louisiana, Oklahoma, and one county in Mississippi. This species has apparently been around for years but the hosts switch to grain sorghum appears to be new. This pest can be devastating to grain sorghum if populations reach high densities. In fact, some fields have seen 100% yield loss. Another major factor is this aphid is difficult to control with currently labeled products.

Importance of Monitoring Square Retention in Young Cotton

👤Angus Catchot, Extension Entomologist 🕔14:23, 19.Jun 2014

Square retention is a critical component of early season plant bug management. I would strongly encourage you to take square retention counts along with your sweep net counts prior to bloom. Not only does this help in the decision making process of treating plant bugs, but it also helps you to get a better idea of how the products you are applying are working. Numbers alone can be deceiving when adults are steady moving into the field. When large numbers of adults are migrating into a field it is not uncommon to have as many or more plant bugs 4-5 days after a spray than you did before you sprayed and it still would not equate to a control failure.

Green Stink Bugs in Non-Podding Soybeans: What to Do?

I have had numerous calls recently on green stink bugs in beans that are either vegetative or at R1-R2 stage with no pods. Numbers have ranged from 4-5 to 8-12 per 25 sweeps depending on the field. It is not uncommon to have a field or two on occasion to have threshold numbers of stink bugs before soybeans put on pods, but the number of fields this year being reported is certainly unusual.
