Phenoxy damage on Soybeans

Phenoxy damage on Soybeans

Every year, if you look hard enough, you can usually find phenoxy chemical damage on almost any soybean field in north central Oklahoma. This year, however seems the worst I can remember seeing. I suspect this is due to an increase in spraying by producers as no-till keeps gaining popularity, as well as the stretch of high temperatures with high humidity and the still evenings and nights we had recently.

Most of the damage looks to be, not drift, but volitization, where the chemical "gasses" off and moves in the atmosphere to off target areas. 

The most common culprit is probably Dicamba/Banvel since beans are very sensitive to it and it is somewhat volatile in hotter temperatures. 24d can also become volatile and can also cause damage.  Very often the two chemicals are used together in chemicals such as Brash, RangeStar, Banvel D, etc. and are very effective weed control chemicals.

Phenoxy damage causes the soybean plant to darken, cup, and pucker it's leaves. If the exposure was severe enough it can also cause the plant to stack it's nodes, putting a number of flowers and then pods close together. Most exposures are not severe enough, and the plant soldiers on with little or no yield loss, but the exposure can cause yield loss (although quite often you won't know how much until you harvest them) and even death of the plant. 

Long story, short, is you need to be careful when spraying phenoxies, and think about your neighbors.  Watch wind direction, heat, and maybe avoid those still evenings after a hot day.                      .
