Question:

We have gotten a question about ANTHEM FLEX (herbicide produced by FMC) and what affect it may have on peanuts. The label states “Check with your local seed company before applying ANTHEM FLEX herbicide to peanuts, regarding the sensitivity of that variety to ANTHEM FLEX herbicide to avoid potential injury.” Do you have any experience with this product or know if it may affect certain varieties of peanuts?

Jordan Answer:

The best timing for this product is within the first month of the season mixed with contact herbicides.  A great deal of research suggests that the visible injury, often reflected in stunting, does not affect yield. It provides good residual weed control but you have to accept a degree of stunting in some instances.

We have not conducted a variety trial but suspect minor differences across varieties.
