As many know - i found this in my beans about a month or month and half ago - It appears to be a - non - event this here as to hurting yields - which at this time little is known about this , But today while surfing the Chat 'n Chew Cafe - came across this video out of the U. of Wisconsin - - thought I would post this up - it may help you to identify this in your fields IF you have it - reason is it looks like there may be a connection to some varieties , and this may help you to plan next seasons beans - if this do's become the case .
Happen hunting !
