Efficacy studies of Aquaprene (1.8% and 2.8% AI) sand granules and Altosid XR-G (1.5% AI) sand granules against first and second instars of Ochlerotatus taeniorhynchus as a preflood treatment in small field plots.
An efficacy study was conducted to evaluate sand granule formulations of Aquaprene (1.8% and 2.8% active ingredient [AI]) and Altosid XR-G (1.5% AI) as a preflood application against Ochlerotatus taeniorhynchus larvae in small field test plots. Aquaprene sand granules (2.8% Al) were applied at 2.5 and 5 lb/acre and the 1.8% AI formulation at 4.2 lb/acre. The 1.8% AI formulation was compared with Altosid XR-G sand granules (1.5% AI) applied at 5 lb/acre. Plots were flooded after 7 days, and 1st and 2nd instars were introduced, pupae were collected, and the plots were drained and dried for 9 days. Assessments were made 21 and 35 days posttreatment. Both Aquaprene sand granules formulations exhibited excellent control throughout the 35-day study.
