My cucumber plant were looking good with a lot of flowers until 3 days ago . In a matter of 3 days all my plant were wilt and looking dead . It does not seem to be caused by cucumber beetle as I really did not see any . I broke off a stem and looked for bacterial wilt desease but could not find anything. the sap was clear and not white nor slimmy.
I had only one large healthy cucumber and then I had tiny cucumber from female flowers that started to develop but did not get any bigger than 1.5 inches...
What I noticed was underneath leaves were covered with yellow uneven dot , all the leaves were covered underneath , it did not really look like eggs are he shape was very uneven . I did see some bugs on the leaves , I had never seen bugs like this before . 3 legs on each side , they are black and long and kinda flat , with yellow dotted stripes on both sides of the body ( alongside) , THEY ARE NOT SPOTTED BEATTLE OR STRIPPED BEATLE actually I wish they were that would solve my problem and I would know why and how to prevent it next time , I can send you a picture of the bug if you want so you can see by yourself .
unfortunately I had to get rid of the plants this afternoon ... but I d like your thoughts on what could have caused it and hope to learn from this for my next crop.
thank you in advance !
