The deposits from suspensions of 11 experimental compounds, Schering 34615, Herc. 9485, GC-9879, Dursban, fenitrothion, GS-13005, bromophos, Mobam, SD-8280, SD-8530, and SD-8211, were evaluated for their effectiveness against on clay, whitewashed clay, plywood, thatch, and cement panels at Savannah, Georgia. Surfaces were maintained outdoors but protected from direct rain and sun. Bromophos at 180 mg/sq ft was effective for 12 to 14 weeks on all surfaces except cement (4 weeks). At 200 mg/sq ft, SD-8530 gave satisfactory kills for 8, 16, and 12 weeks on clay, whitewashed clay, and cement, while Dursban provided satisfactory kills for 9, 6, and 9 weeks, respectively. On plywood and thatch at 200 mg/sq ft, all compounds were effective for 9 weeks or more. Compounds most effective on clay and whitewashed clay were bromophos, Dursban, fenitrothion, and SD-8530. On cement SD-8211, SD-8530, fenitrothion and Schering 34615 at 200 mg/sq ft provided satisfactory kills for 12 to 15 weeks.
