Trickle Irrigation System Injected Insecticides to Control European Corn Borer, 1980

‘Lady Bell’ peppers were transplanted to a Sassafras sandy loam field on Jun 3. Plots were double rows on mulched, trickle-irrigated, elevated beds 5 ft wide and 100 ft long. Experimental design was a randomized complete block with 4 replications. The trickle irrigation system consisted of an electric pump (25 gal/min) with sand filter, 2 in main hose (15 psi), #3 feeder hose (10 psi), and 1/2 in bi-wall, slow-drip hose under the mulch. Systemic insecticides were injected into the 1/2 in bi-wall hose using a 5 gal, CO2-pressurized tank at 60 psi on Jun 12, Jul 15, Aug 4 and Sep 1. Orthene was applied as a foliar treatment with a tractor-mounted boom sprayer with drop nozzles on either side of the row and one over the center calibrated to deliver 83 gal/acre at 250 psi; sprays commenced Jul 14 on a weekly schedule until Sep 10. On each harvest date, 100 peppers were randomly selected from each plot and dissected to determine percent borer infestation.
