Growing cucumbers resistant to the mosaic virus represents your best line of defense. After suffering total crop losses with traditional varieties, I have come to depend on Marketmore varieties. These hybrids are specifically bred to withstand strains of viruses that will quickly wipe out common cucumbers. Secure your harvest each season by smartly selecting your seeds.

Marketmore 86

  • Strong tolerance against CMV subgroup I and II strains
  • Produces straight 8-inch dark green fruits
  • Maintains 80% yield under moderate infection pressure

To ensure complete security, use both resistant varieties and preventive barriers. It may be beneficial to allocate some time to first install a layer of reflective silver mulch before planting to deter aphids. Second, use floating row covers to protect your plants, securing them at the edge. Each of these methods is a valuable practice for me. In outbreak areas, I layer these practices and achieve a 95% success rate. Your plants require this combined method of defense.

Obtain your source seeds from reputable sources, ensuring that you can rely on their resistance claims by checking independent trials conducted by reputable universities. I order directly from the breeders and evaluate their testing procedures. Do not purchase seeds at half the cost from seed companies, as they may contain the virus inside. It is worth the money for healthy crops.

Sustain protection through the season. Inspect plants weekly for symptom development. Remove weeds within a 1000-foot radius that may serve as aphid hosts. I interplant Marketmore cucumbers with trap crops on the perimeter. Your vigilance helps maintain the genetic resistance protection.
