Value of a Sticker-Extender for Sunflower Beetle Larval Control, 1985

The trial was located near Greenbush, MN in Roseau county. Plot size was 4-30 inch rows by 35 ft in length. Treatments were replicated 4 times and were arranged in a randomized complete block design. Insecticide and insecticide plus sticker applications were broadcast applied on 12 Jul using a hand held CO2 sprayer with 40 psi, fan type nozzles, and approximately 20 gal total material per acre. The sticker, Bond, is a latex type sticker-extender. Larval counts were taken on 10 plants 24 h pre- and posttreat and at 120 h posttreat. The data was corrected using the Henderson-Tilton method, transformed using ARCSINE and then compared.
