Tomato brown rugose fruit virus (ToBRFV) is a highly contagious tobamovirus of tomatoes and peppers. It spreads mainly on hands, tools, clothing and seed, and there’s no cure. Infected plants show mottled, crinkled leaves and brown, rough patches on fruit. Bag and destroy infected plants, disinfect everything they touched, and replant with clean seed. It doesn’t harm people.
Fusarium wilt hydroponics problems start when a soilborne fungus, Fusarium oxysporum, enters roots and blocks the plant’s water-conducting tissue. Look for yellowing and wilting, often on one side, plus brown streaks inside the stem. There’s no cure for infected plants, so remove them, disinfect the system, and use resistant varieties and clean starts.
Damping off seedlings collapse because soilborne pathogens such as Pythium and Rhizoctonia rot the stem at the base. Cold, wet, crowded media is the usual trigger. Extension experts say it’s hard to stop once symptoms appear. So prevention is the real fix: clean trays, fresh media, media kept at or above 68°F, less water and good airflow.
White fuzz on roots in water is usually healthy root hairs, tiny outgrowths that absorb water. Healthy fuzz is bright white, dry-looking and firmly attached, and the root under it is firm. Brown, slimy or smelly roots whose outer layer slips off point to Pythium root rot. Fuzzy mold on a sponge surface is usually harmless.
Most AeroGarden troubleshooting comes down to water, the pump and the light timer. Fill the bowl to “Fill to Here,” run the model’s pump test, and prime a pump that hums but doesn’t move water. Reset the light-on time, and clear roots blocking the deck. White fuzz, algae and brown crust are usually harmless, according to AeroGarden’s own FAQ.
