Combining Ingredients To Tackle Tough Weeds
Help can’t arrive fast enough for corn and soybean farmers who routinely battle tough weeds. Here’s a look at three products manufacturers plan to market for weed control in the near term.
BAYER CROP SCIENCE
PREMIX: Convintro
TYPE OF WEEDS: Palmer amaranth (pigweed) and waterhemp
PROPOSED RELEASE DATE: 2023
- Convintro features diflufenican, a Group 12 molecule, and will be used in both corn and soybeans.
- In soybeans, Bayer plans to package diflufenican with metribuzin (Sencor) and flufenacet to boost weed control.
- In corn, diflufenican will be paired with an HPPD inhibitor to boost weed control.
“Convintro targets a site of action in plants that differs from herbicides U.S. growers commonly use.” ~Frank Rittemann, Bayer product manager
CORTEVA AGRISCIENCE
PREMIX: Resicore XL
TYPE OF WEEDS: Up to 75 broadleaf weeds and grasses in corn
PROPOSED RELEASE DATE: 2022
- It features acetochlor (Group 15), clopyralid (Group 4) and mesotrione (Group 27).
- The premix can be used preplant, preemergence and postemergence – including in corn 11" or larger.
- It includes encapsulated acetochlor for enhanced crop safety.
“Corteva is taking advantage of every opportunity it can to look at current modes of action as well as different active ingredients to help farmers.” ~Brandon Walter, Corteva U.S. product manager
SYNGENTA
PREMIX: Acuron GT
TYPE OF WEEDS: Primarily
broadleaf weeds in corn
PROPOSED RELEASE DATE: 2022
- It features glyphosate (Group 9), s-metolachlor (Group 15), bicyclophyrone (Group 27) and mesotrione (Group 27).
- Long-lasting residual allows for early post-emergence use (before weeds reach 4" in height) for optimum yield protection.
- Flexibility allows use in up to 30"-tall corn, in case of a wet spring.
“Its higher-level control of large-seeded broadleaves such as giant ragweed, morningglory and cocklebur, and pigweed species like Palmer amaranth and waterhemp, really sets Acuron GT apart from all other post-emergence-plus-residual herbicides.” ~Ryan Lins, Syngenta research & development scientist
