Summary

The systemic insecticides phorate and Di-Syston were applied at varying rates in bands in the row at planting time. Phorate gave good flea beetle control throughout the season during two years of the three that the experiments were conducted. Di-Syston was less effective.

Di-Syston was considerably better for the control of aphids than phorate. Potato leafhopper control was excellent when either systemic was used except in an experimental trial where Irish Cobbler was planted.

A split application of one half dosage at planting time and the other half applied in the row at mid-season did not appear to have any advantage over a full dosage at planting.
