Comparison of Synthetic Pyrethroid Insecticides for Control of the Sugarcane Borer (Scb), Large-Plot Field Trial, 1983


 Foliar spray insecticide concentrates were applied in water to a field of sugarcane (plant cane crop) located at Little Texas plantation near Labadieville, LA for control of season-long SCB infestations. A randomized complete block experimental design was employed with treatments replicated 3 times. Individual plots ranged in size from 1.7 to 2.3 acres; each plot consisted of a contiguous block of sugarcane surrounded by headlands and ditchbanks. Each spray concentrate was applied in water to the crop canopy from an airplane flown on 60-ft (10 row) swaths at a rate of 2 gal of finished formulation/acre/ application. The first application of insecticides was made after sugarcane internodes were visible above ground and when 5% of the stalks harbored small 1st to 3rd stage larvae in leafsheaths; they were repeated only when that level of infestation was found again in Guthion-treated plots. However, weekly SCB population monitoring was terminated 15 Sep when SCB damage is considered to no longer pose a threat to the Louisiana sugarcane crop. Only 2 applications were required to restrict SCB populations in guthion-treated plots below the economic threshold of crop damage; application dates were 16 Jul and 23 Aug. The efficacy of insecticide treatments was determined 29-30 Sep by comparing the percentages of sugarcane internodes bored (damaged) by season-long SCB larval infestations in treated plots to that found in untreated; 5 (10-stalk) samples randomly selected in each plot were scanned for external signs of internode penetration by SCB larvae.
