The Q&A Archives: Controlling Cucumber Wilt

Question: I am having problem's with wilt on cucumbers. Last year my plants died after about only a length of 3 to 4 ft. I have reason to believe it is a bacterial problem of some sort as I have found no trace of insects. Any help you can provide will be appreciated. Thanks. C watson Evansville, IN

Answer: If you feel you have given your cucumber plants all the conditions for good growing--plenty of sunlight, water, and nutrients, and a rich soil with neutral pH, then you are right to start looking for pest problems. Bacterial wilt is spread by cucumber beetles; they spread the bacteria to the plant as they feed. To test for bacteria, cut a wilted stem near the base of the plant and squeeze out the sap--look for a milky white substance. Touch the tip of a knife to the ooze, and if as you withdraw the knife it strings out in a fine thread, you have a bacterial infection. There is no chemical control for this type of wilt; the best bet is to control the beetles--or better yet, grow resistant varieties.
