| Abstract/Contents: | "Turfgrass managers frequently use Fe2SO4 (chelated or non-chelated) as an additive with MSMA or other organic arsenical herbicides to minimize discoloration of bermudagrass or zoysiagrass. In a 1996 study evaluating at the possibility of reducing St. Augustinegrass injury to MSMA, data suggested control of Southern crabgrass was reduced. The objective of the studies reported here was to determine if antagonism occurred when iron was added to MSMA. In a number of experiments MSMA was applied at 2 lb ai/A in combination with an iron additive in 25 gpa. In duplicate experiments in which 4, 6, or 8 fl oz/A Ferromec® was added, crabgrass control was less than 20% while plots treated without Ferromec® was 60% 1 month after treatment. In a separate experiment, 13 additional products containing iron reduced crabgrass control with a single 2 lb/A MSMA application to varying degrees when used at the labeled rate for the iron additive. Preliminary evaluation of these products suggests that the degree of antagonism was likely a reflection of the iron concentration in these products. Antagonism was observed with Ferromec® used with MSMA for dallisgrass control." |
