Abstract:A new multifunction irrigation system (MFIS) was evaluated in 1983, 1985, and 1986 as a tool for chlorpyrifos applications to grain sorghum for greenbug, Schizaphis graminum (Rondani), control. The unique MFIS chemical nozzling system was evaluated for efficacy or chlorpyrifos rates applied through nozzles either held stationary above or moving within the sorghum canopy, and for efficacy of chlorpyrifos application with and without a nonemulsifiable oil in the spray mixture. Greenbug control was achieved when one-eighth to one-sixteenth of the registered rate of chlorpyrifos was applied through the MFIS. Applications through MFIS nozzles moving within the canopy were more effective with lower chlorpyrifos rates than applications through stationary nozzles. Nonemulsifiable oil need not be added with chlorpyrifos when applying treatments through the MFIS.
