Apply the following in a 7-inch band after seeding. PRSV is devastating in some squash fields in the region and, where this virus is present, resistance to all viruses is necessary. The following control measures should also be used. Plant fields as far as possible from existing cucurbit plantings to prevent aphid transmission of viruses from existing fields to new fields. Also, use reflective mulch to prevent aphid transmission of viruses.
Insect control is essential for prevention of wilt.
Control cucumber beetles before they feed on plants. Alternate chlorothalonil 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. This is a serious problem in some years.
