Use of Neonicotinoid Insecticides to Manage Cucumber Beetles on Seedling Zucchini

P. McLeod

October 2006


The use of neonicotinoid insecticides applied into soil at planting and when zucchini plants had two true leaves was effective against both the spotted and the striped cucumber beetles. At 17 days after planting, significant increases in mean numbers of dead cucumber beetles were detected in all plots receiving insecticides at planting when compared to non-treated plots. When seeds were dipped in imidacloprid mixtures, emerging zucchini seedlings were effectively protected from cucumber beetle feeding.
