Abstract:The objective was to evaluate the health and growth of corn plants after application of foliar fungicide. Treatments were replicated once and randomly assigned to eight, one-acre plots: CON, no foliar fungicide application; V5, one application of pyraclotrobin foliar fungicide at corn vegetative growth stage V5; R1, one application of pyraclostrobin and metconazole foliar fungicide at corn reproductive growth stage R1; and V5+R1, one application of pyraclotrobin foliar fungicide at V5 and one application of pyraclostrobin and metconazole foliar fungicide at R1. Measurements were recorded at R1 and R3 growth stages from two locations within each replicate. At R3, a 24.7% of disease incidence in plants evaluated showed symptoms of Grey Leaf Spot. Treatment V5 at R3 was most effected by Grey Leaf Spot (15%). Northern Leaf Blight was also found in the field, the highest percentage of disease incidence being in CON (10%) and least disease incidence in V5+R1 (1.63%). There was no difference (P=0.52) in the weight of the plants. Applications of foliar fungicide increased the average heights (P<0.0001) . Applications of foliar fungicide at V5, R1, and V5+R1 decreased the number of yellow leaves (P=0.0018). Applications of foliar fungicides increased plant health, and may contribute to a higher quality feedstuff.
