Be on the Lookout for Cucumber Beetles!
Crystal Stewart-Courtens, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
Cucumber beetles will soon be active in the region, so make sure to scout and appropriately protect cucurbits. Young transplants and direct seeded cucurbits are a priority to protect because cucumber beetle feeding early on can vector bacterial wilt, a disease which can kill plants during hot, dry weather and/or heavy fruit set. Many conventional growers choose to treat either seed or transplants with a systemic insecticide which will protect them for a few weeks, after which point additional sprays will be needed to control new adults which fly in. Organic growers can either use row cover or a coating of Surround (kaolin clay) to protect transplants, followed by insecticide sprays later in the season. Both organic and conventional growers should time any insecticide applications to avoid harming the bees. This generally means spraying in the late afternoon/evening.
If scouting for cucumber beetles, check the flowers of older cucurbits first, as this is a very favored location. However, all stages of cucurbit will be fed on.
