TY - JOUR T1 - Trunk Injection of Dicrotophos and Trunk Implantation of Acephate to Control Foliar Pecan Pests JF - Arboriculture & Urban Forestry (AUF) JO - JOA SP - 294 LP - 297 DO - 10.48044/jauf.1980.071 VL - 6 IS - 11 AU - J.D.

Two injections increased foliage retention at the 2 gm/15 cm trunk circumference rate over a single injection. Treatments of dicrotophos had the most significant impact on populations of the black-pecan aphid, and yellow aphids. Acephate trunk implantation was not effective in controlling foliar pecan insects. ER -
