Previous Farm Doctor visits identified downy mildew problems on Manoa lettuce grown hydroponically. Looks like downy mildew is decreasing with warmer temperatures, similar to downy mildew on basil. Both seems to be cool weather diseases on locally grown crops.
However, it appears that powdery mildew is starting to move in.
Typically when LIFE makes Farm Doctor visits, we are alerted to not just 1 grower identified problem, but a number of different issues.
Check out a visit with one of our favorite LIFE growers, Mr. Fred Lau.
