Starting clean and staying clean is crucial for the success of any crop operation. Weeds and other unwanted vegetation can compete with crops for resources such as water, sunlight, and nutrients, leading to reduced yields and lower profitability. To effectively control weeds and maintain a clean field, many farmers rely on herbicides as a key component of their weed management strategy.
One effective approach to herbicide application is using a multi-pass strategy. This involves applying a pre-emergence herbicide before weeds have emerged from the soil, followed by post-emergence herbicides to control any weeds that have already emerged. This approach can be particularly effective for controlling annual and perennial weeds, as well as grasses and broadleaves.
There are several benefits to using a multi-pass herbicide application strategy:
In a multi-pass herbicide program for corn and soybean, it is important to use herbicides with different sites of action to prevent weed resistance from developing. Each herbicide targets a specific biochemical pathway within the plant, and repeated use of the same site of action can lead to the emergence of resistant weed biotypes. Using herbicides with different sites of action provides a broader spectrum of control and helps to prevent the development of resistant weeds.
Another important aspect of a multi-pass herbicide program is overlapping residual. Residual herbicides have the ability to control weeds that germinate after application, but their efficacy decreases over time. By applying herbicides with overlapping residual, the residual activity is extended, providing better control of weeds that may germinate throughout the growing season. This is especially important for crops like corn and soybeans, where the growing season can be long and weeds can continue to emerge throughout the season.
By incorporating different sites of action and overlapping residual herbicides into a multi-pass herbicide program, growers can achieve effective and sustainable weed control, resulting in healthier crops and increased yield potential.
Residual Herbicide + Site of Action = Success
To effectively control tough weeds and prevent the development of resistance, it is important to incorporate a herbicide with some residual chemistry in it, either as a pre-emerge herbicide or an early post-application. Using different sites of action is also crucial in killing tough weeds and preventing weed resistance from developing. By following these steps in your corn herbicide program, you can fight tough weeds and minimize the spread of weed resistance, leading to greater success in your crop production.
Pre-emerge + Post Residual = Success
A multi-pass soybean herbicide program is essential for achieving optimal weed control in any soybean system. To maximize control, it is important to apply a pre-emerge herbicide and partner it with a burndown herbicide if needed, using full rates whenever possible. Additionally, applying a post-herbicide application at the proper weed height (when the weeds are small) and adding post-residual products is crucial. It is also important to consider using different modes of action to achieve effective control. By incorporating these practices into your soybean herbicide program, you can achieve optimal weed control in any soybean system, whether that is Liberty, Roundup, Enlist, Conventional & Xtend, leading to greater success in your crop production.
Overall, using a multi-pass herbicide application strategy can be an effective way to maintain a clean field and optimize crop yields. By targeting both pre- and post-emergence weeds, this approach can provide comprehensive control, improve efficiency, and increase flexibility for farmers.

To get weed and disease control right the first time with a multi-pass herbicide program, it is important to use the right adjuvants. Adjuvants can improve the efficacy of herbicides by enhancing their absorption and retention on plant surfaces, improving coverage and penetration, and reducing drift. Choosing the right adjuvant for the specific herbicide and weed species is crucial for achieving optimal results. By incorporating the right adjuvants into the multi-pass herbicide program, growers can maximize weed control and prevent the emergence and spread of herbicide-resistant weeds and diseases throughout the growing season.
