Cedar apple rust galls on cedar producing spores

Cedar-apple rust galls in Ithaca NY, a sure sign of spring!

This amazing fungus (Gymnosporangium juniperi-virginianae) makes spores each spring that infect apple trees. From there, it makes new spores to reinfect cedar. Quite an evolutionary feat!

Fig. 3. Disease model of tomato yellow stunt disease (ToYSD). Four viruses—tomato yellow leaf curl virus (TYLCV), tomato chlorosis virus (ToCV), southern tomato virus (STV), and tomato brown rugose fruit virus (ToBRFV)—interact with the host immune system in distinct ways, compromising plant defenses and facilitating infection. Their synergistic interactions overcome host immunity, leading to the development of a cryptic ToYSD.

Fusarium dry rot on potatoes, a dark dry lesion

First diagnostic challenge in the new job. This sample was delivered to my mail box with zero information. Just two potatoes. Eventually figured out where they came from.

Is gray fuzz attacking your plants? 🌧️🍄
That’s Gray Mold (Botrytis). It loves COOL & WET conditions.
To stop it:
1️⃣ Increase AIRFLOW (prune!) ✂️
2️⃣ Stop overhead watering 💧
3️⃣ Remove infected parts immediately 🗑️
Save your harvest! 🍓

Sooty blotch on Apple

Sooty blotch is a fungal disease of apple. The pathogen causes dark sooty smudges on the skin. It is mainly a cosmetic issue, as it doesn’t penetrate the fruit's flesh, but it can impact marketability. Sooty blotch is favored by humid wet conditions #Fungi #Apple #PlantDisease 🧪

Black knot on cherry is caused by the fungus Apiosporina morbosa. The fungal disease appears as hard black swellings (knots) scattered in the tree. Infected branches often wilt, fail to leaf out or die beyond the knots. Black knot can be managed through sanitation #Fungi #PlantDisease 🧪

Seeing brown, rotting stems on your beans, peas, or tomatoes? It could be foot rot. Act fast:
* Pull & burn affected plants
* Rotate crops over a 3-5 year cycle
* Use sterilised compost & pots for seedlings
* Ensure plants aren't stressed.
Prevention is key! #GardeningTips #PlantDisease
