Watch for soybean aphids

Kevin Johnson
Field Scientist
Dow AgroSciences

Kevin Johnson, Field Scientist, Dow AgroSciencesSince 2000, when it was discovered in the Midwest, the soybean aphid has quickly become the most serious pest threat to soybean producers. The soybean aphid uses sucking needlelike mouthparts to feed on plant juices.

In large numbers, soybean aphids can reduce plant vigor and growth. Visual signs of soybean aphid damage may include leaf puckering as well as reduced pod and seed counts.

Damage severity varies widely depending on pressure. It can be exacerbated by other stressors on the soybean plant, especially during drought conditions. Soybean aphids are most likely to appear during the primary soybean reproductive growth stages, typically from June through August in the Midwest.

In favorable conditions, aphid populations can proliferate quickly. Aphid movement is often sporadic and difficult to predict, so diligent scouting is important. Consider the following scouting tips:

  • Sample for soybean aphids, beginning when aphids are first noted in fields. Sampling should include whole-plant counts of 20 to 30 plants per field with a threshold of 250 aphids per plant.
  • Look for aphids colonizing the stem of the plant (an inferior quality food source versus leaves). This is likely an indicator that populations of 400 aphids or more are present. Treatment is recommended.
  • Watch for beneficial organisms (Asian lady beetles and lacewings) that serve to regulate soybean aphid populations. Consider the presence of beneficials in treatment recommendations.

Transform® WG insecticide from Dow AgroSciences is proven effective for controlling soybean aphids. Transform is a distinctive new chemistry with a unique mode of action that controls pests that might be resistant to other insecticides.

Once producers spray plants, the foliar-applied translaminar activity of Transform moves from the surface to the inside of the leaf where it will move within to protect the entire treated leaf. Transform provides superior control of soybean aphids via direct contact and ingestion.

In addition to excellent control and proven residual, one of the biggest advantages of Transform is the minimal impact of the chemistry on beneficial insects when compared with pyrethroids and other classes of insecticide products. When applied as directed, Transform® WG insecticide allows predatory insect populations to remain intact to control spider mites.

The superior control of Transform at a low use rate (0.75 ounce per acre) makes it a cost-effective treatment control option for growers. Transform also is tank-mix-compatible with most commonly used crop protection products: nutrients, adjuvants, herbicides and fungicides.

Growers using Enlist Duo™ herbicide share their initial impressions

This season, the Enlist™ Weed Control System from Dow AgroSciences has taken a big step forward with the launch of Enlist Duo™ herbicide. Growers from around the United States are sharing their experiences with Enlist corn, Enlist soybeans and Enlist cotton throughout the season.

plant_deathThe growers, representing several key production states, have been impressed with the efficacy, lack of drift and exceptional crop tolerance from Enlist Duo.

“The application of Enlist Duo went very well, and there was no problem with drift,” reports Keith Kenny, Iowa grower. “The herbicide landed right where it was sprayed.”

In Indiana, Mike Lewis says Enlist Duo controlled his difficult weeds while having no ill-effect on his crop.

“You could see the ragweed completely turn over within hours after application,” Lewis adds. “When you’re worried about glyphosate-resistant weeds, the Enlist system gives you another tool to combat those issues.”

Growers also have expressed their excitement for what’s to come.

“We applied Enlist Duo, and we had excellent weed control,” said Todd Hanten, South Dakota grower. “I was happy to see how it performed on my farm with my field and my acres. I’m excited. We’ll be increasing our acres with Enlist.”

Dow AgroSciences reveals the name of its new corn herbicide

Dow AgroSciences has announced that its new corn herbicide, previously referred to as GF‑3471, will be named Resicore™ herbicide. Registration for this herbicide is expected in 2016.

Luke Peters announces Resicore herbicide.

Luke Peters, corn herbicides product manager, announced Resicore™ herbicide, the name of a new weed control tool in corn, through a wood carving at a recent Dow AgroSciences media event held in Indianapolis.

“Resicore is designed to control weeds throughout the season,” says Luke Peters, corn herbicides product manager, Dow AgroSciences. “It will provide trusted residual control, resistance management and resounding yield potential as the core of growers’ weed control programs.”

Resicore will help growers control herbicide-resistant weeds through three nonglyphosate and nonatrazine modes of action. The active ingredients included in this novel formulation are acetochlor, mesotrione and clopyralid. Resicore is expected to offer flexible application timing from preplant to early postemergence.

In 2014 trials, Resicore had a 97 percent efficacy rating on many common weeds found in Midwest fields, including waterhemp, marestail, giant ragweed and Palmer amaranth.1

Currently, waterhemp populations have shown resistance to a specific mode of action in 18 states.2

“By implementing a weed control program that consists of multiple modes of action and uses herbicides with residual control, growers can combat heavy weed pressure in cornfields more effectively,” Peters says.

Scouting for weeds such as waterhemp is essential to ensure timely herbicide applications and to identify problem fields for the following year.

resicore_logo“Waterhemp continues to top the list of troublesome weeds for corn growers,” Peters says. “With three active ingredients that have never been formulated into a single product before, Resicore is a new, unique option for growers in programs to control waterhemp and other herbicide-resistant weeds.”

Curb nitrate leaching to support conservation efforts

This summer across the Midwest, corn growers have faced excess rainfall and an increased risk of losing essential nutrients such as nitrogen. Growers can support environmental stewardship by applying a nitrification inhibitor to prevent nitrogen loss and keep nitrogen where it belongs: in the root zone.

Nitrogen can be lost through leaching and denitrification. Fortunately, there are ways growers can prevent nitrogen loss through the responsible application of a nitrification inhibitor.

“Using a nitrification inhibitor keeps more nitrogen available to corn crops at the root zone and reduces leaching of nitrogen into the groundwater,” says Tiffany Dean, nitrogen stabilizers product manager, Dow AgroSciences. “Nitrapyrin is designed to inhibit nitrification and found only in N-Serve and Instinct II nitrogen stabilizers.”

Many states have implemented plans to decrease nitrogen loss through environmentally beneficial farming practices. One example is the Iowa Water Quality Initiative that offers growers a $3 per acre rebate, for up to 160 acres, if they try N-Serve® nitrogen stabilizer for the first time with their fall anhydrous ammonia application.

Along with state initiatives, programs such as the 4R Nutrient Stewardship program encourage growers to implement environmentally sustainable practices. The 4R program is a concept to use the right fertilizer source, at the right rate, at the right time, with the right placement. The 4R framework takes an innovative approach that provides educational tools, advocacy support and implementation recommendations for crop nutrient stewardship.

“We are proud to support conservation programs, such as the 4R program, that recommend management practices to help growers increase production, boost profitability and improve environmental sustainability,” Dean says.

Growers confirm no drift or volatility issues with Enlist Duo™ herbicide

As the Enlist™ Weed Control System moves forward, Dow AgroSciences is working closely with growers and retailers as they use Enlist Duo™ herbicide in-crop for their weed control needs.

Physical drift, or the movement of spray particles, and volatility, or vapor drift, can both cause conflict with neighboring farms and residents. With Enlist Duo herbicide featuring Colex-D™ Technology, growers experience the benefits of not only near zero volatility and minimized potential for physical drift but also low odor and improved handling characteristics.

Colex-D Technology is composed of new 2,4-D choline, the latest formulation science and a proprietary manufacturing process. This season, many growers and applicators are sharing their first reactions after managing the Enlist system on their farms.

“It was amazing how the spray dropped straight to the ground with zero drift,” said Andy Thies, a field agronomist with a Nebraska cooperative. “And, there was no smell at all. Even standing near the sprayer, I didn’t smell a thing.”

Lab and field data show that with Colex-D technology, Enlist Duo alone can reduce driftable fines by up to 45 percent. When paired with low-drift nozzles, the reduction is up to 90 percent — empowering growers to use it on their farm without concern.

In addition, near-zero volatility helps keep Enlist Duo in place to improve control. The new 2,4-D is up to 96 percent less volatile than 2,4-D ester. When compared with other products, Enlist Duo is 99 percent less volatile than a mix of DGA dicamba and glyphosate herbicides.

“After using Enlist once, we’re sold — it took care of our problem weeds,” said Steve Wertish, Minnesota grower. “And with Colex-D Technology, we can go into the field with confidence and know it’s not going to drift.”
