The key to a successful weed control program starts with a pre-season herbicide treatment. The mantra of ‘start clean, stay clean’ highlights the importance of early intervention for producers aiming for optimal weed management throughout the season. As we transition into spring, producers are actively implementing their "burndown" applications, recognizing the critical role they play [...]
The time of year is rapidly approaching when producers should start thinking about protecting their farms with burndown and pre-emerge herbicides. All the moisture received across the High Plains in the last few months will contribute to early weed emergence. The idea of starting clean and staying clean is crucial to a successful farming operation. [...]
The long-awaited genes that have been bred into soybeans and cotton to allow the use of dicamba over-the-top of these crops got off to a rocky start in 2017. Whether all the cases of ‘off-site’ dicamba damage were truly from the increased use of dicamba during the growing season, the EPA and the states are [...]
If you are involved in agriculture, you have been inundated with information about resistance management. Most of the conversation is centered around herbicide and insecticide resistance that is occurring due to the ability of plants and insects to adapt over time to repeated applications of a similar active ingredient. Many of the issues we deal [...]
Herbicides play a major role when it comes to controlling weeds, while protecting the environment. By knowing what to expect from different herbicides, a weed control program can be put in place that meets the goals of each farm, both from an economic as well as an environmental standpoint. There are two broad categories of herbicides, [...]
We all know the importance of mixing different modes of actions in post emerge herbicide programs. One area of corn herbicide management that is easy to neglect is to stay on a consistent rotation of early corn herbicides that are used preplant or preemerge. We are all creatures of habit and resist change. When we [...]
Controlling weeds is becoming a difficult and expensive task. A common assumption made when a group of weeds are not killed by a herbicide application is that the weeds are resistant. While weed herbicide resistance is unfortunately common, other factors can play a role. The weather is a huge variable in farming which directly affects [...]
As crops, and of course weeds begin to emerge this spring, many producers may not be aware of the process their Crop Quest Agronomist uses to select appropriate herbicides for control of these weeds. There are a multitude of questions that need to be answered before a particular herbicide and timing of application can be [...]
Roundup resistant weeds in cotton have become a major problem, so starting clean is key to finishing clean at harvest. Under conventional till, we need to consider using the old “yellow” herbicides, like trifluralin - preplant incorporated - to help with our weed control. Under no-till & strip-till systems, there are other options for burndown [...]
With the recent dry summers in the Southern Plains, interest in moisture conserving alternative crops has increased. One new forage that has shown great potential in North Central Oklahoma is teff grass. Teff is a summer annual forage native to Ethiopia that is very broadly adapted. It can tolerate a wide range of soil conditions, [...]
Managing and controlling herbicide resistant weeds has become a huge issue across the United States for over a decade. Each year we see new states and additional weeds added to the list with confirmed resistance. Producers are being forced to move away from low cost glyphosate-based herbicide programs in search of newer herbicide technology that [...]
During the growing season, there are numerous (too many) opportunities to treat weeds post-emerge – both in crop and on summer fallow ground. It is important to keep a few things in mind to insure proper weed control after making your herbicide choice. The herbicide and proper rate alone does not insure you will attain [...]
Mid December through January is the ideal time to apply pre-emergent or dormancy herbicides for mustard control in alfalfa. Applications of DuPont™ Velpar® or Velpar® AlfaMax™ Herbicide will provide control of winter annual weeds like Tansy mustards and Shepardspurse. These products provide contact and residual control. Both Velpar® and Velpar® AlfaMax™ should only be applied [...]
Soybeans are a great option for producers to utilize in rotation. Soybeans are not only good for the soil, they are also a good option to clean up fields for other crops in a rotation situation. To avoid weed pressure concerns, producers in Northeast Kansas tend to practice preventive treatments in the fall and early [...]
“It’s vital to use Roundup Ready Alfalfa when planting hay in the spring,” agrees Rob Benyshek, Crop Quest Western Region Vice President and Eric Konrade, Crop Quest Division Manager, Garden City, KS. No other pre-emergent herbicides can be used on spring planted alfalfa, which is why it is important to utilize this Roundup Ready trait [...]
