Field experiments were conducted in corn plots during 1988 that were artificially Infested with stalkborers, Papianema nebris (Guenee'). Two atomizers, a flatfan and a flood nozzle chosen for different droplet size distributions were used to apply two insecticides, chlorpyrifos and cyfluthrin at two application rates. Nozzles, insecticides, rates, and associated interactions were evaluated for control of stalkborer in the field. Laboratory studies involved application of insecticides to soil and glass via a spray track for bioassay at field application rates. Image analysis of percent area travelled on water sensitive paper by stalkborers was compared to droplet percent area covered to obtain percent area contacted per insect. Droplet size distributions for each nozzle were obtained using an Aerometrics particle sizing instrument. Significant differences in stalkborer control were attributed to percent area covered by smaller droplets measured by image analysis. |
