Reduced ultraviolet light transmission increases insecticide longevity in protected culture raspberry production
Michigan State University TunnelBerries personnel, Heather Leach and Rufus Isaacs along with colleague John Wise, recently published results from their study examining the effect of UV light transmission through different tunnel plastics on insecticide longevity in the journal Chemosphere. Results of this research indicate that tunnel plastics which block UV light transmission can prolong the effectiveness of insecticides used to manage insect pests.
We just finished the last harvest of potted raspberries in a high tunnel in Benton Harbor, Michigan. Plants were pruned last winter to two floricanes per plant. The relatively hot summer shortened the floricane harvest and reduced yields, whereas the long warm fall enhanced the primocane crop. Prelude had good yields this year, but produced small berries. For overall yield and fruit quality over the last two years, outstanding cultivars have been Kweli and Imara.
