| Post subject: | Black Spot Tomato Fungus |
We are new to aquaponics. We have an IBC tank/grow bed, where we planted several varieties of tomatoes and peppers. One of our tomato plants got a black spot fungus which quickly withered the leaves. The fungus spread to the other tomato plants as well (but not the peppers). As a novice gardener, I didn't react quickly enough and we lost all of the tomato plants; they have been removed. Now, here is my main question: We use hydroton as our grow medium. I am assuming that it is now infected with fungus spores. Because of this, I am reticent to reintroduce tomato plants into the same grow bed. Are there any suggestions out there? Should I worry? Should I just keep that grow bed quarantined from tomatoes and plant other things? Is there a way to clean the hydroton? Should I dispose of the hydroton and use fresh medium? Any suggestions or experience dealing with fungal diseases is appreciated. FYI: Our system is kept outside, in the warm southern california weather. Our humidity level is quite low. |

More than likely that there are spores there from whatever fungus killed your tomato plants. It's important that you identify and remove any of the infected tissue from the area (do not compost it). If you know what killed the plants then you'll have an idea of how to treat the area. You'll also be able to select resistant varieties. I would recommend growing a different but non-susceptible crop in the area where you had the tomatoes but not another member of the nightshade family. If your space is very limited and your set on growing the same thing then pick a variety that's resistant to the fungus that killed your tomatoes. Avoid any splashing, spraying or top watering of the leaves from either the AP water, sprinkler or garden hose. Got any pics of the plants that had fungus? Here's a comparison of some diseases that cause spots on tomatoes. I wouldn't follow the mulching advice they give (not for AP anyway). http://www.rodalenews.com/tomato-problems |

Have had a similar incidence a while ago , just grow a different variety that is resistant to the fungus that killed your tomotoes and you should be fine |
