Monsanto Collaborates with Adjuvants Unlimited to Develop Dicamba Sprayer System Cleaner

Monsanto officials say the compound is the first-ever agricultural sprayer system cleaner designed to deactivate dicamba.

Monsanto Company announced today that it has collaborated with Adjuvants Unlimited, LLC to develop what it describes as the first-ever agricultural sprayer system cleaner designed to deactivate dicamba. Adjuvants Unlimited, a developer and manufacturer of technologies for the crop protection industry, will bring this technology to market in 2018 through their industry partners, say Monsanto officials. 

The new sprayer cleaner technology is unique from other currently commercially available sprayer equipment cleaners as it is based on a chemical process that deactivates certain pesticide active ingredients, including dicamba. This technology is designed to be used within the rinse and cleanout processes specified on current dicamba product labels and best management practices. 

“Monsanto developed this product based on grower interest in new tools to help manage the use of multiple herbicide systems, including the Roundup Ready Xtend Crop System,” said Ryan Rubischko, Monsanto dicamba portfolio lead, in a company news release. “This is a new mode of action for sprayer system cleaners and will provide growers an even better experience when utilized as part of the Roundup Ready Xtend Crop System with XtendiMax herbicide with VaporGrip Technology, a restricted use pesticide.” 

Monsanto officials say the firm has been working with Adjuvants Unlimited and academics over the past few years to test this technology prior to bringing it to market. 

“We have been testing this new technology in university trials and it has proven to be very effective at cleaning sprayer systems that have contained dicamba tank mixed with additional herbicide products,” said Dan Reynolds, a Mississippi State University weed scientist. “We have seen a significant reduction in the presence of dicamba when utilizing this technology as part of the labeled sprayer cleanout process.” 

Monsanto and Adjuvants Unlimited anticipate that the initial product offering will be announced in the coming weeks and available for the 2018 season, and additional branded products and distributors will be available in the future.
