Three levels of hail damage, measured by plant defoliation, were simulated on July 14, 2017 using a string trimmer to corn at the V14 growth stage; simulation levels were 0%, 30%, and 60% defoliation. Foliar treatments were applied on July 17, 2017, three days after the simulated damage. The foliar treatments included:
A) Ammonium thiosulfate 12-0-0-26S (ATS) at 5.19 gal/acre
B) Headline AMP® fungicide at 12 oz/acre
C) Headline AMP fungicide at 12 oz/acre with ATS at 5.19 gal/acre
D) KS2075 (20-0-7.5-5S) liquid fertilizer at 1 gal/acre
E) KS2075 liquid fertilizer at 1 gal/acre with Headline AMP at 12 oz/acre
UT) Untreated control
ATS was diluted to a 100 gal/acre application rate to prevent crop phytotoxicity.The study was set up as a randomized complete block with three replications.Yields and plants that died prematurely were recorded.
