Evaluation of Foliar Insecticides for Management of the Sugarcane Aphid in Grain Sorghum, 2015: Table 1

A study was conducted at the LSU AgCenter Dean Lee Research Station in Alexandria, LA to evaluate insecticides for management of the sugarcane aphid. Six foliar insecticide treatments and an untreated check were assessed in an RCB design with four blocks (one replicate per block). Grain sorghum (Dekalb DKS53-67) was planted on 3 Jun on 38-inch centers at a density of 83,100 seeds per acre. Plots were four rows wide and 35 ft long. Insecticide treatments were applied on 31 Jul after sampling two leaves per plant from 25 randomly selected plants in each block revealed that sugarcane aphid densities had reached 112 aphids per leaf on 30 Jul. A high-clearance self-propelled sprayer with a compressed-air …
