Don’t Let Mother Nature Get You Bent out of Shape

May 16, 2013
Studies have shown that uncontrolled weeds can cause more than $20 billion of damage to crops in the United States annually. But with an effective and flexible herbicide program, growers can fight yield-robbing weeds, even in adverse weather conditions.
While a farmer may have the best intentions for a timely herbicide application, Mother Nature may bring rains that keep him out of the field. If he has chosen a flexible herbicide with pre-emergence and post-emergence flexibility, he can still apply it when conditions allow. But if he selected one with limited application flexibility, he may have to make a last-minute switch to another product.
Some herbicides are limited to pre-emergence application or can only be applied up to 2-leaf corn, while others offer a more flexible application window up to 12- or 30-inch corn.

Field Corn Label Comparison

Application Timing
Lexar® EZ herbicide
Pre-plant through 12-inch corn
Lumax® EZ herbicide
Pre-plant through 12-inch corn
Zemax® herbicide
Pre-plant through 30-inch corn

Pre-emergence only

In addition to delivering application flexibility, Lumax EZ, Lexar EZ, Zemax, Callisto Xtra and Halex GT are Resistance Fighter brands, offering multiple effective modes of action to combat resistant weeds. In fields where glyphosate is not performing like it used to, these products decrease dependence on glyphosate.
Moving away from a glyphosate-only post-emergence application is not only the best agronomic choice for weed management, but it maximizes yield potential. It’s really important to put a product down from a pre-emergence stand point to control those residual weeds so when you do come back and make a post-emergence application with a product like Halex GT, you won’t have nearly as many weeds present at that application time. You’ll put a lot less pressure on those post-emergence products. Early-season weed management really pays, and growers really see it in the bin at the end of the year.
Syngenta herbicides are also flexible when it comes to tank mix compatibility. Farmers can also tank-mix Quilt Xcel® fungicide with Halex GT for early (V4-V8) application in corn for added convenience and maximized yield. While some combinations of insecticides and herbicides can injure corn, the unique chemistry of Force® insecticide makes it safe to use with any corn herbicide program.
Bottom line: With an integrated weed management program like Lumax EZ or Lexar EZ followed by Halex GT, growers achieve application flexibility, and also the potential to see an increase in both yield and profit. At Syngenta, we are focused on developing herbicides that deliver flexibility and resistance management, and at the end of the day deliver the best weed control for the grower to help them grow more corn.

Pest Patrol Program Expands to Help Tackle Weeds

May 09, 2013
Now in its second year for the Midwest, the Syngenta Pest Patrol program has expanded to offer more agronomic updates throughout the year, providing growers with valuable information that can help them maximize the yield potential of their soybeans. 

Palmer amaranth young
Previously offering updates on insect threats from May through September, Pest Patrol coverage is now available through December and covers a host of topics including field conditions, nematodes, insect and disease pressures, and weed management strategies.
"Last year, Pest Patrol was a great resource for soybean growers. Now that it has expanded to cover an even broader range of pests, participation in this program is a must for all growers trying to boost their yields," said Les Glasgow, technical product lead, Syngenta. "The weed management strategies will be especially useful with the spread of herbicide resistance into the Midwest."
From coast to coast, there are 30 different states battling 14 different glyphosate-resistant weeds. Growers in states such as Kansas and Ohio must now learn how to effectively keep their fields free of aggressive, resistant, yield-robbing weeds like Palmer amaranth. Through the Pest Patrol program, growers can take the first step to Be Part of the Solution in the fight against herbicide resistance.
Pest Patrol offers timely updates on pest pressures and treatment recommendations to growers and retailers through weekly audio updates accessible via the toll-free hotline (877-285-8525) or website, In addition, users can register to receive an SMS text message alert each time a new local update has been posted. With real-time pest alerts, growers can customize their pest management plans to fit the conditions in their specific region.

Experts advise PNW sugarbeet growers to prepare for leafhopper, curly top

May 03, 2013


Sugarbeet growers in southern Idaho and eastern Oregon don’t like beet leafhoppers. At all. And it’s not because the tiny insects prefer sugarbeet plant stems as their food of choice – it’s because during their sugarbeet foliage feasts, beet leafhoppers can infect plants with curly top virus, a devastating disease transmitted to the plant by this insect.
While leafhoppers and curly top virus are not new to sugarbeet growers in the Pacific Northwest – area reports about the pests date back to the early 1900s – they remain a threat to sugarbeet crop production every year. Advancements in genetic and pesticide technology now allow growers to better protect themselves from the beet leafhopper, and ultimately, curly top virus. By properly identifying, preparing for outbreaks and monitoring fields, sugarbeet growers can keep leafhoppers and curly top at bay to better realize yield potential.
It takes two: Know your enemies
Beet leafhoppers and curly top virus exist in a symbiotic relationship in which the virus depends on the insect to travel and infect crops. While virus-free leafhoppers cause damage to sugarbeets, they shouldn’t be a target pest for growers.
The leafhopper, which is about an eighth of an inch long, wedge-shaped and pale green, gray or brown, serves as the only insect vector by which curly top viruses can travel and infect fields. Once infected with a strain of the curly top virus, sugarbeet plants will have smaller, crinkled leaves that curl upward and inward. Plant veins will also become more apparent, swollen rootlets become shaped irregularly and root and beet growth is stunted. A new rootlet system will then grow, resembling the hairy appearance associated with Rhizomania, although the diseases are unrelated.
Growers should regularly monitor their fields and apply crop protection products appropriately to help prevent curly top and contain plants already affected. Containing the disease can help prevent the virus from infecting other fields and will help salvage what’s left of an infected crop.
When hot and dry, leafhoppers fly
It is difficult to predict annual pressures from leafhopper and curly top until seasonal conditions begin to unfold as winter ends. Warmer temperatures allow farmers to plant sugarbeets early, but can also indicate leafhopper behavior for the upcoming season – when winter desert host plants die in hot, dry weather in the spring, leafhoppers seek new hosts, including sugarbeets.
The Pacific Northwest has seen relatively cool spring weather the past few years – cool enough to keep leafhopper and curly top pressures low. While these recent trends have been favorable for growers, experts warn that there really is no indication for how heavy leafhopper and curly top pressures will be this growing season.
Natural resistance – and beyond
Sugarbeets are naturally prepared for curly top without assistance from genetic engineering or pesticides. However, this naturally occurring resistance becomes stronger as the beet grows, which means young plants are more vulnerable to the disease and insect.
While sugarbeet’s natural tolerance to curly top is beneficial, the plants aren’t able to fend off heavy infestations alone. Ensuring protection from beet leafhopper and curly top can be achieved with resistant seed varieties and application of the proper crop protection products.
To help sugarbeet growers keep their crops pest-free and realize full yield potential, Syngenta offers Hilleshög® brand varieties and CruiserMaxx® Sugarbeets insecticide/fungicide seed treatment, a combination of separately registered products, for systemic protection of leafhopper. Drawn from a genetic portfolio spanning more than 100 years, Hilleshög brand high-quality seeds deliver unmatched curly top resistance to keep sugarbeet plants healthy and strong.
"Hilleshög seed is a leader in genetic tolerance for curly top resistance, and CruiserMaxx Sugarbeets helps further protect crops from curly top," said Doug Ruppal, sugarbeet crop specialist at Syngenta. "CruiserMaxx controls beet leafhopper in the critical early-life stage of the plant. As sugarbeets emerge they begin to systemically take up the insecticide from CruiserMaxx Sugarbeets, which will control beet leafhoppers in young plants."
Prepare to fight from the start
While beet leafhopper and the curly top virus have always been a problem for Pacific Northwest sugarbeet growers, advancements in research and breeding technology have made the crop profitable despite the century-long battle growers have had with the pests.
And given all the modern technology and crop protection, Ruppal recommends preparing for, rather than reacting to, beet leafhopper and curly top infestations from the start each year.
"Once curly top starts infecting the plant, it’s too late for growers," he said. "It is always a good idea to have sugarbeet plants protected from the beginning. You just never know when beet leafhoppers and curly top are going to enter a field."
