In the weed science world, we spend a lot of time discussing soybean herbicide programs, but very little time talking about corn programs. Why is so little time spent on corn? One reason is the fact that we can use Group 27 or HPPD herbicides in corn to achieve effective weed control. HPPDs were approved in the late ‘90s, making them the most recently approved herbicide group to come to market. Therefore, there are fewer resistant weeds reported compared to many other herbicide groups. Today, Group 27 herbicides are the foundation to many successful corn herbicide program. However, in 2020, farmers in approved states/counties will have the option to use Alite™ 27 (isoxafl utole) for residual on tough-tocontrol small-seeded broadleaf weeds, such as pigweeds and marestail. Alite 27 has greater activity on smaller-seeded broadleaf weeds versus larger-seeded weeds like giant ragweed.

With the new herbicide-tolerant traits on the market today and the many to come in the near future, this is a good opportunity to discuss some common herbicide injury symptomology that is documented every year.

As you start to plan your post-herbicide application trip for your soybean crops, you may be looking for ways to maximize weed control. With the ever-growing list of resistant weeds, proper weed management techniques are more important than ever. Heavy spring rains may cause the pre-emergent herbicides to break down earlier in some fields this year. Therefore, another layer of in-season residual herbicide will be critical this year.

In times of lower commodity prices, we’re always trying to find new ways to cut cost. One area to consider is cutting costs on soybeans is your fall burndown program. But, before making that decision, you should evaluate the benefits of a fall burndown.

In agriculture, we are always looking for the next new tool or management practice that will allow us to become even more successful. When it comes to weed control, new opportunities are very limited even though new trait technologies are either on the market or pending approval. In the past few years, there has been a limited release of new herbicide active ingredients. It’s been almost two decades since a new mode of action has been released. With fewer herbicide modes of action and active ingredients available, weed control has become even more challenging than in past years.

One question that farmers are faced with each year is how they should manage their soybean herbicide program. With multiple herbicide systems on the market and the possibility of new traits becoming available, the decision becomes more difficult.

By this point in the season, farmers are looking to control weeds that have emerged following a break in residual activity. When making a weed control plan, there are several things to keep in mind. Check out the video below to learn more.
