cucumber leaves yellow, some with irregular white spots
Comments (3)The white areas look like they are dried out, not like something is growing on top. I added some 5-3-4 fertilizer last weekend following the manufacturer's instructions because the squash next to it was looking a little yellow too. The squash has greened up but the cucumbers did not. I guess I'm wondering if I should rip them up and re-plant, because I probably still have time. Or maybe just cut off all of the lower leaves that look like this. It's a bit heartbreaking because there are lots of mini-cucumbers on the vine already....See MoreYellow spots on cucumber leaves - can anyone identify? (Pictures)
Comments (3)The lesions confined by the veins look like angular leaf spot caused by the bacteria Pseudomonas syringae. It's pretty common on cucumbers. It survives on plant debris so sanitation is a big part of control. It also hangs out in the soil, so rotating out to something less susceptible for a few years would help. If re-planting with cucumbers, it's best to use pathogen free seeds if you can. I'm not really sure how that works in a home owner situation. There are also resistant varieties available. Unfortunately, there isn't any way to get rid of it now that you have it. You can slow the spread by watering early in the morning to allow the leaves to dry more quickly. Also, only pick fruit when the plants are dry....See MoreYellow spots on otherwise healthy Marzanos
Comments (4)Not a blight. Please post a picture of the entire plant. need to see the "normal" leaves in the same images as compared to the newer leaves....See MoreCucumber leaves spots and yellowing
Comments (5)Mine look like that too and I chalk it up to late season old age combined with insect damage, possibly spotted or striped cucumber beetles with help from some squash and stink bugs. By mid Aug my cuke plants are exhausted, so I plant more by late May to prolong the harvest......prolong it a little bit as these pests love new digs....See Morealisande
