What is the residual control with Sonic® herbicide?
Sonic® herbicide offers two nonglyphosate modes of action to provide long-lasting residual control. Taking advantage of this preemergence herbicide to control weeds early can help farmers' time, obtain better full-season control and protect more yield.
How effective is Sonic® herbicide to ALS-resistant weeds?
Sonic® herbicide is powered by two modes of action, attacking weeds multiple ways to effectively manage herbicide resistance and protect yield potential. It provides residual control on a broad spectrum of weeds, offering the flexibility to be applied preemergence up to three days postplant.
Is Sonic® tank-mix-compatible with other herbicides?
Sonic® is tank-mix-compatible with many other herbicides. For additional information on Sonic and the tank-mix compatibility, read the product label.
What’s the best approach to control waterhemp and marestail in soybeans?
Resistant waterhemp and marestail can cause anxiety for any farmer. Fortunately, there are some specific tips when looking to control these two resistant weeds:
Start with a clean seedbed. For marestail specifically, apply a burndown herbicide to control it early.
In spring, apply a residual herbicide, such as Sonic® herbicide, for an additional layer of early season control.
Scout fields to determine postemergence approach.
What are the benefits of using Sonic® for fall weed control?
Taking action against weeds in the fall can pay big dividends in the spring. That’s because controlling actively growing fall weeds can eliminate the need for, or increase the effectiveness of, any spring burndown herbicide program.
Using Sonic® herbicide has five big benefits to fall weed control. Sonic:
Allows for spraying on actively germinating weeds when control is most effective.
Spreads out workload, giving farmers greater flexibility in the spring.
Decreases weed competition to maximize the yield potential of emerging soybeans.
Optimizes timing of spring applications to be made on smaller, more uniform-sized weeds.
Is easy to handle and mixes well with other herbicides for broad-spectrum control.
How much rain does it take to activate Sonic® herbicide?
Rainfall is needed for any herbicide to take effect in the soil for controlling weeds. The timeliness of needed rainfall partly depends on the soil temperature following application.
When soil conditions are cooler, weeds aren’t germinating as quickly, which gives you a little more time to receive rainfall. Under normal conditions, receiving rainfall within seven to 10 days is ideal. If it’s extremely warm and it’s a late-spring application, an activating rain within three to four days will provide optimum performance.
