Plant fields as far away from existing cucurbit plantings as possible to prevent aphid transmission of viruses from existing fields to new fields. Both diseases can produce foliar symptoms that are often overlooked. Early detection is important, since control in the foliar phase can reduce infection of developing fruit. Both diseases are seedbome and can survive on infested debris for at least one year or until the debris decomposes. Apply the following when disease is first detected on the foliage and repeat every 7 to 10 days.
Insect control is essential for prevention of wilt.
Control cucumber beetles before they feed on plants. Begin sprays when vines run. Alternate chlorothalonil or maneb with Quadris every 7 days. This is especially important to delay the development of resistant strains of the pathogen to Quadris. Apply chlorothalonil or Quadris on alternate weeks when using these fungicides.
