This is terrific. Writing is a way to think; waiting to write until you've worked everything out is counterproductive. On the discomfort of thinking through writing, from @patthomson.bsky.social

Early Blight disease of tomato

Early Blight disease of tomato

Early blight on hydroponic-tomatoes caused by the fungus Alternaria linariae. Lesions develop on lower leaves as small black spots with concentric rings. Lesions often surrounded by a yellow halo. The disease can reduce yield; fungicides offer control πŸ§ͺ 🌱

Rhizopus fruit rot appears as a white fungal growth on damaged strawberries. Fruit becomes soft & watery. Mucor & Botrytis gray mold are also post harvest fungal diseases that look similar. Field sanitation & cooling harvested fruit will minimize damage. This was after 2 days in a moist chamber 🌱 πŸ§ͺ

We think you are dealing with mealybugs. The stickiness you mentioned gave me the idea.

It has a wide host range that includes most broad leaf crops. It produces while fungal mycelium with the tan-brown sclerotia. The sclerotia allows the fungus to go dormant in absence of host for years. Image is of Sclerotium rolfsii on tomato. Tan structures are sclerotia. You are welcome

Yes, Sclerotinia sclerotium
can affect PF causing Sclerotinia rot, appearing as dark lesions on fruit, stems & leaves. A white cottony growth appears in cool (15-20 C) moist conditions that causes plant decay & mushy fruit. A similar fungus Sclerotium rolfsii also attacks PF under warmer weather

Sclerotinia stem rot is a plant disease caused by the soilborne fungus Sclerotinia sclerotiorum. The disease causes stem rot or white mold on winter canola when conditions are favorable. The pathogen forms black hard resting structures called sclerotia. The disease also affects soybeans πŸ§ͺ 🌱
