Weather Watch: What Does Warm and Dry Mean for Early Wheat Development?

Sep 26, 2012
As the hot sun beats down on wheat fields and dry, cracked soils span for acres, many cereal growers ponder how such conditions may impact their crops this fall and into next season. Winter wheat is often faced with high temperatures and dry conditions that can severely impact and delay germination, emergence, root development, stand establishment and tillering. In addition, unfavorably warm and dry weather is conducive to other early developmental challenges, like the onset of damaging soilborne diseases, which can translate to decreased wheat yields.

No Disease, Please
 
According to Patricia Okubara, Ph.D., research geneticist, USDA-ARS at Washington State University, soilborne pathogens can cause significant economic damage in cereal crops, and the addition of unfavorable weather can make matters worse. Soilborne diseases like Pythium, which need cooler weather to survive, may be curtailed by very warm and dry weather, whereas diseases like Fusarium crown rot and common root rot pathogens may have higher tendencies to thrive in such conditions. 
 
"Warm and dry weather can certainly impact soil pathogens and affect root health. It’s an abiotic stress," Okubara explains. "That stress, in addition to what is in the soil and the cultivar of wheat planted, enables certain diseases, like Fusarium for instance, to move in more easily. Conversely, pathogen damage to roots can also exacerbate drought damage. Drought will impact the yield over and above what the pathogen is doing, and that severity can vary regionally," she adds.
 
Soilborne and seedborne diseases, such as common root rot and dry seed decay, respond more to drought stress than other pathogens and occur more frequently in low rainfall, dryland winter wheat-growing areas. Dry seed decay, for example, can rot seeds planted in warm, very dry seedbeds and can grow on grain when the relative air humidity is as low as 80 percent or even less. The resulting impact can be a lack of germination or decreased stand emergence, which can further reduce yields. Research from Montana State University indicates damage from these diseases is most severe in already stressed crops.
 
"You need to have the pathogen and favorable or conducive conditions for damage, which certainly happens in some locations," Okubara notes. "Wheat needs water to develop properly. In Washington State, for example, it can get quite warm, and there are drought years here," she explains.  "And drought can have a negative impact on root health. If you have too much of it, crops will naturally struggle."
 
Currently, an important objective in wheat breeding programs is to improve wheat’s tolerance to heat and drought stress. Okubara notes that wheat breeders are also breeding for cultivars that can grow rapidly downward into the soil in search of moisture. "These varieties will grow further into the ground to find water," Okubara says. "When there is adequate moisture, the roots really take up the water to produce nice yields."
 
In addition to ample moisture, healthy root systems also need protection from underground pathogens that can often go unnoticed but cause substantial damage. Syngenta recently introduced the Vibrance™ family of cereals seed treatments, featuring Vibrance Extreme fungicide and CruiserMaxx® Vibrance Cereals insecticide/fungicide seed treatments, to improve root development and disease protection while boosting RootingPower, the link between strong roots and higher yield potential. Vibrance branded products deliver enhanced, longer-lasting disease protection through the power of sedaxane, the new seed treatment active ingredient from Syngenta designed to increase overall root health and quality. RootingPower also helps cereal crops produce healthier, stronger stems and foliage that are better able to withstand stresses from weather, diseases and insects.
 
Overcoming warm, dry weather conditions can be challenging, especially since they are impossible to control. Nevertheless, to help avoid yield loss, it’s critical to assess field history and consider all variables in production, including proper variety selection for specific growing conditions, as well as quality seed treatments for disease protection. With the goal of rapid germination and emergence in mind, experts suggest seeding when soil temperatures are 55 degrees or lower to help evade certain soilborne diseases. Using a hoe drill to plant deeper into moisture and waiting for rain to plant are strategic options, too. Even in challenging weather, effective agronomic practices and management, proper irrigation and just a little mercy from Mother Nature could prove to be an effective recipe for a successful wheat crop.

To Treat or Not to Treat—That is the Question

Sep 19, 2012
Shakespeare once wrote, "To be, or not to be, that is the question." Today, the more relevant question is "To treat, or not to treat – seeds, that is."  Farmers are inquiring about the best options when it comes to seed treatments. Well, the answer is treated seeds. 
 
Treating soybeans has become considerably more popular recently because the benefits are seen early in the season, as well as during harvest time. Today, Syngenta is playing a leading role in the seed treatment market through innovation, ingenuity and invention. 
Soybean Stine 1
 
According to Syngenta research, did you know:
 
  • Over a decade ago, less than 10 percent of soybeans in the United States were treated with a fungicide seed treatment. 
  • Last year, 24 percent of soybean seeds were treated with a fungicide seed treatment.
  • Today, nearly 50 percent of seeds are treated with a combination of an insecticide and fungicide seed treatment. 
 
Because of this rapid increase in usage, the bar has been raised in soybean production. This is allowing farmers to break through yield barriers to earn an increased return on investment. Plus, choosing treated soybean seed offers many benefits. Syngenta research shows treated seeds defend and protect against problematic diseases like soybean aphids and tedious pests like Pythium, Phytophthora, Fusarium and Rhizoctonia, and the bean leaf beetle. Treatments also help improve seed germination, seedling emergence, stand establishment and plant vigor. 
 
By using treated seeds over untreated seeds you will give your soybeans an advantage in yield, quality and profit potential. Try CruiserMaxx® Beans insecticide/fungicide combination applied with Vibrance™ fungicide seed treatment. This offering for the 2013 season will provide effective insect and disease protection in addition to increased root health. Using CruiserMaxx Beans applied with Vibrance will result in bigger, more developed plants, which can lead to higher yield and increased profit at harvest. 
 
Ask yourself the question, "Should I treat my seeds next season?" With all the offered benefits the answer should be a yes!

What do an Olympic Athlete and a Soybean Plant Have in Common?

Sep 05, 2012

No, this isn’t the punch line of a bad joke. Believe it or not, soybeans have more in common with Michael Phelps than you may think. As many of you know, Phelps beat the world record for the number of gold medals achieved during an Olympian’s career. Many attribute his success to his physique: height, narrow torso and long arms. Like an Olympic swimmer, high yields in soybeans are often attributed to their structure: extended roots, strong stems and large foliage. Although the summer Olympics won’t be back until 2016, soybean growers still have to plan for the upcoming 2013 growing season.

For many soybean plants, Rhizoctonia could keep them from reaching their Olympic potential this upcoming growing season. This soilborne disease can cause seed rot, root rot and lesions on the germinating seedling. Rhizoctonia damping-off generally occurs during seed germination, but the stem rot phase can occur at any stage. According to Ohio State University Extension, it thrives under a wide range of moistures and temperatures. Damage from this disease results in soybean yield loss. Premature death of diseased plants is also a possibility.

To control this disease, Syngenta will offer CruiserMaxx® Beans insecticide/fungicide, a combination of separately registered products, applied with new Vibrance™ fungicide seed treatment for the 2013 growing season. Providing enhanced disease protection with best-in-class Rhizoctonia activity, growers won’t be disappointed with CruiserMaxx Beans applied with Vibrance. Protecting a soybean’s roots may not win a gold medal in the Olympics, but it will earn high-yielding profits.
