Malus ioensis 'Plena' (Bechtel crabapple) is susceptible to cedar-apple rust and apple scab. I'd suggest that rust is providing you with the yellowed foliage.

There are many disease-resistant crabapples on the market, and I bet most of yours fall in that category if they don't show foliar problems. What are some of the other types you are growing?

Much farther off topic, I just had the pleasure of visiting Bend a few weeks ago. Stellar - we had a big old time romping around the lava beds south of there. Utterly devoid of crabapples...
