Cucumber. First noted two weeks ago. symptoms progressed. Growing conditions - full sun. I noticed yellow spots on cucumber leaves, that looks like mildew. Please recommend me how to get rid of it by organic way, because its already harvesting. I tried just cut off infected leaves, it helped but only for short period.

It looks like your cucumber plant has one of several leaf spot diseases, most likely anthracnose. There really isn't anything you can do about it this year. You can prune out the affected leaves and discard them in the trash (do not compost them). In the future, look for cucumber varieties that have disease resistance. Cornell University has a good list of varieties. http://vegvariety.cce.cornell.edu/main/showVarieties.php?searchCriteria=cucumber&searchIn=1&...
