| Abstract: | "Field studies in corn (Zea mays L.) were conducted during the summer of 2000 to evaluate distribution patterns of corn grits treated with MCA (4-methoxy cinnamaldehyde). Aerial application was used in a 8 ha corn field situated in south-east Hungary. Corn granules ('grits') of 10-12 mesh size were applied on July 18th, August 1st and August 28th at rates of 18.3, 21.9 and 20.2 kg grits/ha and were covered with 80, 119 and 120 g MCA/ha. Experiments were evaluated by collecting grits in 30-cm plastic saucers and by counting grits accumulated on leaves and in leaf axils on corn plants. Analysis revealed a statistical difference between MCA treated and untreated grit application rates only at the first application date. Variation in grit number per unit area and frequency of corn granule number per plant showed some transient technical application problems. However, altogether, grit distribution patterns indicate that aerial application is a viable tool for disseminating MCA in corn fields. With it, orientation disruption of the introduced maize pest Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae) recently introduced into SE Europe will come within reach" |
