Tomato Diseases in Home Gardens!
There have been several folks come to the office and/or call the office this morning with “septoria” leaf spot on tomatoes. Please be advised of this infection if you are growing tomatoes in your home garden. Fungicides sprays applied every seven to 14 days, depending on the frequency of rainfall, help to slow the rate of this (as well as early blight) spread. Garden fungicide products containing chlorothalonil or mancozeb perform the best. Also, several bacterial diseases have been identified in the last week (due to weather conditions), which are difficult to control during periods of frequent rains. Fixed copper products may help in control efforts if mixed with chorothalonil or mancozeb. Please see the attached publication for additional information.
