To assure that virus-free raspberry varieties remain virus free during field propagation of planting stock requires the application of an effective program for the control of the mosaic vector Amphorophora agathonica Hottes. In New York the aphid is present in the field from mid-May through late October and control is needed throughout the entire period. Several foliar spray materials were investigated and were found to lack the needed persistence for a continuous protective program. of those tested, Niagara 10242 (2,3-dihydro-2,2-dimethyl- 7-benzofuranyl methylcarbamate) was the most effective. Granular systemic materials applied over the row provided greatly improved control in comparison with the foliar spray applications. of the materials tested, Temik®, a 10% granular formulation of UC-21149 (2-methyl-2- (methylthio)propionaldehyde O-(methylcarbamoyl)oximc), was consistently the most effective. The results suggest that 2 applications of Temik, 1 in mid-May and 1 in early August, at a rate of 6.0 lb actual UC-21149 per acre to the rows (2-foot row on 4-foot center), will provide effective season-long control of the aphid.
