Description
Summary:Thirty-one insecticides were applied for control of WCR larvae in no-till and conventional tillage corn. The test plot was planted in a continuous corn field on the UK Spindletop Research Farm on 7 May in a RBD with 3 replicates of no-till and 3 replicates of conventional tillage. Individual plots consisted on single rows, 8 m long, with 96.5 cm row spacing. All plots received Accent 75WDG (0.0313 lb [AI]/acre) on 14 Jun. All insecticide treatments were applied at planting except the 2 Furadan 4F treatments, which were broadcast and banded, respectively on 25 May. Number of lodged plants per plot was recorded 28 Jul. A plant was considered lodged if the angle between the base of the plant and the ground was less than 45°. Root damage ratings were evaluated on 29 Jun by examining 3 plants per plot using the Iowa 1-6 system. Data were subject to ANOVA and treatment means compared to that of the control by Dunnett’s test.
