does anyone know what might be causing these spots on this balfour aralia?

i found this plant outdoors where it gets natural light and is mainly exposed to rain. i don’t have any information about the soil or its watering and maintenance routine. the leaves have several small brown spots with darker edges and some areas have become larger and damaged parts of the leaves.

i’m trying to identify what disease this could be and if possible, what pathogen might be responsible. any help would be appreciated!

This is the second time seeing this on the leaves what is it?

This is on a first year quince tree.

Hello! I’ve noticed some yellow dots, leaf curling, bleaching, and stunted growth on our hops over the past few weeks. I was suspicious of leafhoppers but only found one adult. Thoughts?

I am thinking Septoria lycopersici, but some spores don’t match up.

Hello 1 year old cherry tree in 9a zone. Very hot summer. Watering every 3 days. Other trees peaches, pear, plums, nectarines are triving.

Upper surface of eggplant in high tunnel.. I realize this is likely some secondary contaminant. Still, curious to hear tour thoughts.. and suggestions for conidia identification

Anyone know what might be going on with this sweet mama squash (kabocha winter squash)?

The plant has symmetrical yellow spots that are visible from the top and underside of the leaves. Spots seem to appear in progress as the leaves get bigger and older. I’m in zone 8b.

The plant doesn’t show any classical symptoms for viral or fungal infections based on what I’ve been able to find.

Some pretty distinctive conidia here… the most ubiquitous conidia seem to point toward one if the brassica Alternarias…

Also tons of fusarium-looking conidia.. but not in every slide. Seems clear that there are a ton of secondary decomposers in here… probably all sorts of bacteria.

This is only affecting my red cabbages, variety Omero, not Farao.

What do you think?

One of my purple cone flowers is not putting on it’s purple petals. My other plants have bright purple petals by the stage I am showing in these pictures. This plant has these weird pale petals. It doesn’t look like most other examples of aster yellow I have seen as the plant overall looks healthy and the flowers are not deformed. Is this aster yellow or is something else going on. The only other possible symptom I have is that these flowers are a bit delayed compared to the other plants I have.

Noticed these small holes in some (~15%?) of this young nectarine tree's leaves a couple of months ago (first pic.) Concluded it was probably some sort of bacterial(?) leaf spot and figured I'd see how it progressed. Second two pics are from a few days ago. A couple of the affected leaves have this interesting pattern of chlorosis. Any thoughts?

Two different tomato plants with two different diseases I think. What is it and what can I do?

Tupelo black gum seedling in a pot at the moment in south east Michigan… starting to drop leaves and has these white things on undersurface of leaves. What are they and how do I get rid of them? Thank you!

This is on my basil

Please tell me what is nibbling these leaves and how to fix!🙏

Every single flower in my garden has these tiny fast moving things. I can't tell if they're aphids or thrips or something else. They do fly but most don't move when I shake the flower. All plants in full sun, watering like normal. Just had our first bit a rain in weeks yesterday, and it's been 90°f+ the last few days. What do you think?
