BASF Takes the Guesswork out of Decision-Making


Farming is going digital, but it can often be confusing to determine which tools truly help with the decision-making process. Growers wonder which products and technologies are going to put their money to work with the greatest efficiency, and now is the time of year to determine exactly that.

BASF is helping growers make better residual herbicide decisions for their crop protection plan

with a free and easy-to-use data source based on a field’s expected rainfall. The new Herbicide Activation Tool, from BASF, is available online at This new tool instantly translates weather data into agronomic insights by showing predicted rainfall based on compiled historical rainfall data and specific geographies. Growers can then choose the right herbicides for their individual growing conditions.

This knowledge is important because timely, adequate rainfall is essential for activating residual herbicides and delivering needed weed control. The Herbicide Activation Tool can be used to show how likely area fields will receive the necessary rainfall to activate a herbicide during key application windows. This helps growers work more efficiently with what they can’t control — the weather.

How does this benefit a grower’s operation? The tool shows a forecast for eight weeks out as well as historical views for the past 10 years. For example, Armezon®​ PRO herbicide and Outlook® herbicide both activate with just a quarter inch of rainfall compared with up to an inch required with other rain-dependent herbicides.

In most cases that means you’re 2.5 times more likely to get activation with Armezon PRO and Outlook compared with competitive herbicides for a more consistent performance. Armezon PRO and Outlook herbicides have a lower use rate than competitive herbicides to control broadleaf and grass weeds such as waterhemp, pigweed and nightshade with a wide application window.

To proactively avoid expensive and time-intensive resprays, apply a preemergent herbicide like Verdict® herbicide. This helps put weed management back in a grower’s control. Verdict herbicide followed by Armezon PRO herbicide has a 0.5 percent respray rate nationally. This low respray rate makes every dollar on a grower’s farm work harder for them so they can stay focused on the business of growing crops instead of hoping their herbicide activates.

BASF is committed to developing innovative solutions, and the Herbicide Activation Tool is one example of us creating a product that is easy to use and that helps growers make better decisions for growing better crops.
