The economic benefit of insecticide treatment in plantations up to 6 year old of loblolly pine (Pinus taeda) and shortleaf pine (P. echinata), in order to control Rhyacionia spp., was studied at 10 sites in the southern USA. DDT spray was applied repeatedly during the first 3 years and granular phorate annually in the 4th to 6th year old and stand measurements at 15 year old are tabulated. The height of treated trees was significantly greater than that of untreated controls. Treatment significantly increased stand volume in P. taeda but not in P. echinata, giving increased yields of 3.9 and 0.4 cords/acre respectively. It is concluded that the discounted cost of presently available treatment (both the agents tested have been banned) is greater than the increased return.
