An old joke has it that cockroaches and whatever other object that seems to have more than nine lives will be the only things to survive a nuclear bomb. More recently, many growers have laughed that cockroaches and Palmer amaranth will be the only things to make it out alive.

All joking aside, Palmer amaranth — also called Palmer pigweed — is a formidable foe that seems to quickly evolve to resist just about any control method thrown at it. As with most pests, prevention is a lot easier and more economical than dealing with the invader once it becomes established.

Along with prevention goes a zero-tolerance policy. Earlier this decade, University of Arkansas Cooperative Extension conducted grower education on the Vicky Boyd importance of zero tolerance for glyphosate-resistant Editor Palmer amaranth, says Dr. Bob Scott, who at the time was Extension weed specialist. He is now director of the university’s Rice Research and Extension in Stuttgart.

Even a single resistant pigweed plant that went through a combine could forever infest a field, Scott says, citing research by colleague Dr. Jason Norsworthy. Instead, Extension specialists urge growers to pull the few pigweeds in their field to prevent a much larger problem from developing.

And he says he believes the zero-tolerance message got through to a lot of growers.

When Scott first became director of the rice research facility in 2018, a neighboring grower called him out about pigweed along the station’s south border.

“Around here, they don’t let those things to go seed,” the grower told Scott, who promptly grabbed a hoe and removed the 14 offending pigweed plants.

The problem of herbicide-resistant Palmer pigweed has continued to expand, both in acreage as well as the number of chemicals to which the weed has grown resistant.

Earlier this year, Kansas State University researchers confirmed a Palmer amaranth biotype resistant to Group 4 herbicides, including dicamba and 2,4-D. University of Tennessee Extension weed specialist Larry Steckel is following up on similar grower reports that the latest generation of dicamba products is not controlling pigweed like they did when the Xtend system was first introduced in 2013.

In addition, Norsworthy and fellow University of Arkansas weed scientist Tom Barber have confirmed Palmer pigweed populations in Northeast Arkansas with multiple resistance to S-metolachlor, a Group 15 herbicide, and glyphosate.

These latest findings join the growing list of herbicides to which Palmer amaranth has become resistant. They are Group 2 (ALS inhibitors), Group 3 (dinitroaniline such as Treflan), Group 5 (atrazine), Group 9 (glyphosate), Group 14 (PPOs) and Group 27 (HPPD inhibitors).

Although several Palmer amaranth populations resistant to two different modes of action have been confirmed around the country, researchers in Kansas and Arkansas have found populations resistant to five different modes of action.

On top of that, North Carolina researchers have identified a pigweed population resistant to glufosinate, a Group 10.

All of these discoveries lend even more credence to weed Extension specialists’ long-standing mantra, “Start clean, stay clean.”

Soil test results are only as good as the quality of sample submitted

By Nutifafa Adotey

COURTESY JASON OTT, TEXAS A&M AGRILIFE

P

lanning to get the most out of your crop next spring? Soil testing after harvest is a valuable step in accomplishing this goal.

While soil testing is the only practical means to adequately evaluate the nutritional needs in a field to prescribe appropriate lime and fertilizer recommendations, the reliability of soil test results depends on the quality of the sample submitted to the soil testing laboratory.

Poor sampling can result in inaccurate soil test results and produce unreliable lime and fertilizer recommendations.

Here are some helpful soil sampling tips: } Soil samples can be collected at any time, but some soil properties [soil pH, phosphorus (P) and potassium (K), for example] can vary depending on the time of sampling. } While soil test results from University of Tennessee Soil, Plant & Pest Center come back within three to five days, it is best to sample months ahead of planting to allow for planning and getting prices on lime or fertilizer. Check with your local laboratory about their turn-around time. } A good rule of thumb for soil sampling is to collect samples in a way that adequately represents the soil in that field. A well-represented sample will consist of 10-20 core samples taken at the appropriate depth within a 5- to 10-acre grid. } University of Tennessee Soil, Plant & Pest Center as well as commercial soil testing laboratories in Tennessee recommend taking soil samples to a depth of 6 inches. } The frequency of soil testing depends on cropping intensities, soil types, fertilization rate, tillage methods and weather conditions; however, fields should be tested every two to three years to estimate the residual nutrient levels. For high-value cash crops (tobacco, vegetables, etc.), soils should be tested annually. } Soil testing is also recommended any time a nutrient deficiency

problem is suspected or at the beginning of a different crop rotation system. } Soil samples and a completed soil information sheet can be taken to your county Extension office or directly sent to University of Tennessee Soil, Plant & Pest Center, Nashville. If you farm in another state, contact with your local county Extension office about how and where to submit your samples. } Addition information about UT Soil, Plant & Pest Center can be obtained from your county UT Extension offices or at https:// ag.tennessee.edu/spp.

Trimble launches new spot spray system Trimble has introduced WeedSeeker 2, its next-generation spot spray system. By sensing individual weeds in a field and targeting them with a localized herbicide application, farmers can significantly reduce herbicide use, according to a news release. The technique is especially useful to fight herbicide-resistant weeds.

New intelligent sensors save time by eliminating the need for system reset. After a quick calibration upon powering on, WeedSeeker 2 automatically adjusts on the run to changing temperatures, ambient light and shifting backgrounds like soil or stubble, assuring sensor accuracy in all conditions.

The smart sensors also know the speed and their position on the sprayer boom. That means they won't spray sections of the field that have already been covered and will automatically adjust spray timing when making a turn to ensure a weed is covered.

The system now logs every weed sprayed, so users can see in real time where problem areas are and review detailed maps from records before the next spray. WeedSeeker 2 is lighter and more TWITTER: @SOYBEANSOUTH

agile on the largest sprayer booms, and the sensors now provide expanded coverage areas.
