Make sure you look at containers closely before adding the contents to a tank that is going to be sprayed to emerged peanuts. Each year, someone applies glufosinate (Liberty) or glyphosate by accident to emerged peanuts. It is easy to do. Sometimes we (I) use an old jug for surfactant or for additional measuring. On occasion, folks have picked up one that has glyphosate in it rather than surfactant. The surfactant load in glyphosate can look a lot like surfactant. One quart per 100 gallons of glyphosate or glufosinate can cause a lot of injury and reduce peanut yields dramatically.

The answer is to never reuse a container for a different purpose. I know this is easier said than done. I’ve done it. But this really does increase the likelihood that the wrong thing ends up in the tank.

We replanted the peanuts in this plot as soon as it became obvious of what we did. If you realize you sprayed glyphosate ot glufosinate on peanuts, try to trace back the rate you used. My suggestion with a surfactant rate or higher, either plant more peanuts or shift to soybeans. When I waited for peanuts to recover, they never really did. Try not to let too much time slip away from you as the peanuts die and you ponder what to do.
