Residual soybean weed control pays

Dec 29, 2009
Gordon Vail
This harvest left a few surprises, especially from “economical” total-post glyphosate herbicide programs, particularly in soybean. Even though the growing season was delayed, many weeds – like waterhemp and giant ragweed – thrived with plenty of rain this summer, creating a seed bank that will need to be managed next season and beyond.
It makes sense to use a strong residual program for your soybean crop. Research by Bryan Young from Southern Illinois University has shown that a pre-emergence herbicide followed by glyphosate will out-yield two properly timed post applications of glyphosate by 3 bu/A, when glyphosate was applied to weeds <4” tall. 
So, if soybeans are at $10/bu, you can do the math: Using a soybean residual herbicide could return $30/A more in gross profit than two applications of glyphosate. The yield advantage of the residual followed by glyphosate program increased to 6 bu/A when glyphosate was applied to weeds up to 8” tall, which is certainly not uncommon, especially in a year like 2009.

Customized solutions to control glyphosate-resistant weeds

Dec 22, 2009
To fight glyphosate resistance, you need the right weapons. Whether you’ve experienced glyphosate-resistant weeds or are trying to reduce the likelihood of resistance developing, you need a plan. The Resistance Fighter Solutions Builder at can help you develop that plan.
By answering a few simple questions you’ll find management recommendations to consider based on your situation. The Solutions Builder helps find herbicide solutions tailored to individual fields.  Each solution is customized by crop, weed, county, state, preferred management methods and history of resistance. 
  • - Answers to common glyphosate resistance questions
  • - University research and information
  • - Crop strategies to build a resistance management program
  • - Opportunity to join the conversation about glyphosate weed resistance, including the blog from Syngenta experts, articles and radio broadcast clips

Online training modules

Anthony Transou

One of our goals is to provide innovative, helpful tools for growers. And so, Syngenta is introducing the Online Training Courses on This web-based training provides details on the most up-to-date Syngenta solutions to challenges in your fields.

The presentations include audio voiceovers and the ability to click through at your own pace. They cover agronomic challenges faced by growers and Syngenta herbicide, fungicide and insecticide solutions. Our current courses focus on the soybean portfolio.

This information can help you formulate a crop protection treatment plans for the coming growing season. Check them out and let me know what you think.

Seed treatment rebate program

Dec 15, 2009
David Long
Are you interested in trying the latest technology in corn seed treatment? Have you experienced the value of protecting soybeans against early-season insects and diseases?
Pair ‘em Up for Profit provides growers an opportunity to do all of these things. This program offers growers a per-unit rebate on corn seed treated with a nematicide/insecticide/fungicide seed treatment with the purchase of insecticide/fungicide treated soybeans.
Choosing to protect valuable, high-performing seed with seed treatments not only saves money, it also promotes increased plant stand, uniformity, vigor and yield by guarding crops against a broad spectrum of pests. Protecting seed from the moment it is in the ground improves potential for a higher return on investment.

Contact your local Syngenta sales representative for more information.

Liquid CRW insecticides

Dec 11, 2009
Caydee Savinelli

Soil-applied insecticides deliver consistent performance, especially under heavy insect pressure. One of the most trusted options for corn rootworm and early-season pests is available in a convenient liquid formulation and a complete delivery system

This formulation saves time, reduces exposure, is easier to load, and offers several other benefits. Growers appreciate the ease of use, and have seen results.  Check out a comparison between liquid formulations and granular products.

Seedbank stocked for next season

Dec 08, 2009

Harvest tells you what worked and what didn’t work any given season. Both your yield monitor and what you see from the combine cab help you decide what you might want to change next year.  But sometimes you need to get a bit closer. 


One of my colleagues in Wisconsin reported that he walked numerous fields during harvest, and found many small, late-emerging weeds, just 5 to 6 inches tall, dropping a significant amount of seed.  Those will be among the weeds you will need to manage next year. 


In soybean, an early spring residual herbicide could help you get off to a strong start in 2010.  The University of Missouri says, “Our data indicate that early spring applications of residual herbicides provide better control of emerging summer annual weed seedlings than fall herbicide applications.”


With glyphosate- and ALS-resistant weeds becoming more common issues in soybean fields, herbicide selection and application timing are critical. Residual soybean herbicides with two modes of action will provide broad-spectrum weed control and help fight resistance.  Plus, a spring pre-emergence application is your best bet for yield protection.

Break down seed treatment combinations: Fungicides

Dec 04, 2009
Soybean seed treatments have proven their value, and now more choices are available to protect soybeans from early-season insects and diseases. Many of these options combine several active ingredients into one package. It can be confusing to decide which option is best for your crop, but head-to-head comparisons of active ingredients that control the same pest spectrum can help clarify. 

and early-season Phytophthora are diseases that decrease soybean stands. But for these diseases, mefenoxam delivers nearly two times the disease fighting power of metalaxyl, making it more effective at much lower rates.

Although it is not systemic, fludioxonil has the unique ability to adhere to particles in the root zone, which allows it to move with the root system as it grows. It offers more activity on Rhizoctonia and Fusarium than pyraclostrobin, with the added benefit of seed-borne Sclerotinia and Phomopsis protection.

Did your residual herbicide help you survive the weather?

Dec 01, 2009
Gordon Vail
For many growers, harvest this fall wasn’t as much fun as it usually is. In fact, it may not be over yet. Weather challenged you all season long, from a cool, wet spring to a cool summer to a prolonged, wet harvest. The result was high moisture content and low test weights. 
So did your herbicide program in 2009 help you control weeds all season long, despite the weather? Did you see late-emerging weeds that may have produced seed while you were combining? Or did you see the results of not being able to make timely herbicide applications last spring, either in weedy fields or yield losses?
Unfortunately, you can’t control the weather. But you can choose herbicides that can help you protect your corn and soybean yields. Look for herbicides with:
> Residual control – to manage multiple weed flushes
> Wide application windows – so you have more time to get the herbicide on the fields, regardless of weather
> Multiple modes of action – to manage against weed resistance
> Long-lasting residual – because you need to prevent weeds through crop canopy
