Problems with / Spots on Bean, Berry and Cucumber Leaves

Asked June 16, 2018, 4:12 PM EDT

Hi - I'm seeing redish spots on both my Christmas Lima Bean Leaves and my berry bush leaves (rubus oderatus and blueberry) that look like rust fungus (I'm really hoping NOT.) Can you help identify? (See pics of bean leaves - berry leaf spots look similar.) the spots are on both the top and bottom, so maybe not rust ... I've already removed the affected bean plants, but would rather keep the berry bushes if I can. There was also a weird transluscent patch on one of my bean leaves. Japanese beetle? My lower cucumber leaves are also getting spotted. Yellow in some places (nutrient deficiency?) but spotted in others (blight?) My lower zucchini leaves are also yellowing. Any help you can provide in identifying the various causes would be much appreciated. I'm a relatively novice backyard gardener: I can get things to germinate and grow, but keeping them healthy without resorting to chemicals has been a challenge.

This has been a wet season and many vegetables have been affected by too much moisture, lack of sunlight, poor drainage, nutrients leached from soil, etc.
Left photo - translucent areas on bean cannot say for sure. maybe old chewing damage, environmental, etc.
Middle photo - looks environmental
Right photo - cucumber - may be some leaf spots or environmental.

It is not too late to replant from seed. See our vegetable profiles on cucumber, bean, and zucchini.

You can send photos of the affected foliage on the berries.
