Stem Borer in Okinawan Sweet Potato
Started a few slips which were doing fine until a few weeks ago. Now they are getting hammered by some kind of stem borer. Leaves wilt, turn yellow, exit holes and frass visible, lots of little gray wormie guys burrowing thru the stem.
Any controls (preferrably organic) for these guys? Are the Okinawan SP's particulary susceptible? Maybe i just can't grow SP's in my garden?
Vegetable gardening is SO much fun!
