Hello friends of science! I’m migrating over here from X. There, I had 3,000 followers enjoying plant pathology content! Please help me rebuild. I’ll post plant disease photos, management info, science & nature content. Kicking off with some tomato late blight caused by Phytophthora infestans.

🧪 Where did the potato blight come from? 🥔

Researchers have now traced the origins of Phytophthora infestans - the cause of the Irish Potato Famine - to the Andes.

Во-первых покупая цветочки обращайте внимание не их состояние. Если видите паутину, белый налет, то цветок заражен.

Tomato blight is a fast-spreading fungal disease triggered by warm, wet weather. It turns leaves brown/rotten & ruins fruit on the vine.

To stop it:
🍅 Water only the soil (not the leaves)
🍅 Space plants out for good airflow
🍅 Remove lower leaves
🍅 Trim & destroy infected parts ASAP (don't compost!)

In 2023 I painted asparagus Phytophthora rot, caused by the oomycete Phytophthora asparagi.

www.hgpenningtonart....
The painting shows a sprouting asparagus crown, with 12 storage roots, three asparagus spears and two green buds. The three asparagus spears are deformed, with long dark-green lesions near their bases. There are dark brown lesions on the rhizome at the centre of the crown, and on the thick storage roots.
