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 🌱

Winter Temperatures below 15Β°F causes strawberry leaves to turn red, look scorched or appear distorted, often indicating damage from winter desiccation. While leaves may die, the main concern is damage to the central crown (internal browning) which can kill the plant or reduce yield πŸ§ͺ 🌱 #strawberry
