Quantify the significance of application timing and formulation on sweet corn response to dicamba.
Field experiments will be conducted in Urbana and Macomb, IL to quantify the significance of application timing and formulation on sweet corn response to dicamba. The experimental design will be a split-plot arranged as a randomized complete block with four replications. Main plot will include sweet corn hybrid; with hybrids differing in genotype for sensitivity to other P450-metabolized herbicides (mesotrione and nicosulfuron). The subplot factor will be a factorial of formulation and timing; field use rate of dicamba versus dicamba + cyprosulfamide applied at V3, V6, and V9 vegetative growth stages. A non-treated control will be included. Data will include: crop injury 1 and 2 weeks after treatment, silking date, crop yield (ear number, ear mass, number of malformed ears, number of ears broken by husking bed, and additional measures of recovery).
