By soft immature beans do you mean green unthreshed pods, or do you mean threshed green "butterbeans"IJ How much are you getting docked at the elevatorIJ I would check with your elevator and make sure what they want. Around here, they don't want us threshing out green beans, they would rather have unthreshed green pods. Plus, it's been my experience that not many unthreshed pods make it into the probe anyway. If they're already running 12%, I wouldn't wait unless they were really docking you hard. You're losing money as you lose moisture. I've learned with early beans down here to just accept some green pods in the sample. They rarely dock us for them. You can also use Gramoxone on the beans to dry down the green pods and stems. We used some of it this year, where low areas of fields that got too much rain were still green. It worked well, but then it costs some money too.
