My zucchinies were doing well for the past month. Recently leaves turn yellow, flowers had rotted before they opened. One zucchini has not had flowers and new leaves do not grow. Watering is on repulse basis and fertilizer has been applied accordingly. There are cucumber beetles in our garden but they are under control. What kind of damage can cucumber beetle do to zucchini?
Thanks for your help.
Thank you for contacting the Toronto Master Gardeners.
Zucchini and pumpkins are part of the same family as cucumbers. Similar insect pests and diseases will impact all plants in the family. Furthermore, the cucumber beetle potentially can carry bacterial wilt.
