Three systemic fungicides (HOE 2873,HOE 6052, and HOE 6053) were tested fortheir effects on the rust of two varieties ofcorn (native corn and DK 1106) grown: under field conditions in the wet season. Theresponse observed varied with the cornvariety. Application of these systemic fungicidesresulted in delayed disease incidence.With variety DK 1106, the three fungicideswere effective in increasing yieJd, but. onlytwo of these fungicides (HOE6052 and HOE6053 applied as foliar spray and seed dressingrespectively) promoted increase in yield inthe native corn. The results are discussed inthe light of the current literature on systemicfungicides.
