My Sweet, Corn
Spring is here this week, weatherwise, at least. Not to bring back bad memories, but with real spring just around the corner, now is a good time to revisit two or three of last year’s worst pest problems, and plan some sort of counteraction. Not that those memories are really that bad; the interaction of pests, plants, the environment, and my hopefully green thumb is always interesting.
The most serious pest problem last year, most serious because it affected one of my favorite vegetables, was a disease that devastated my later plantings of corn. Looking at the symptoms — yellow streaks on leaves that turned to tan, dead areas — my diagnosis was the bacterial disease, Stewart’s wilt. Some plant pathologists pointed out that Stewart’s wilt is very rare around here, and that the problem was probably the fungal disease, northern corn leaf blight.
