Abstract

Field tests in 1962 and 1964 on control of the lygus bug Lygus elisus (Van Duzee), and onion thrips, Thrips tabaci Lindeman, on Gila variety safflower, Carthamus tinctorius L., resulted in excellent control of both insects by dimethoate. Phosphamidon provided very effective initial control but did not give satisfactory residual activity Control was less with trichlorfon, Bay 25141 (O, O-diethyl O-[p-(methylsulfinyl) phenyl] phosphorothioate), carbophenothion, azinphosmethyl. endosulfan, diazinon, dieldrin, naled. carbaryl, fenthion, and Union Carbide UC 20047A (exo-5-chloro-6-oxo-endo-2-norbornanecarbonitrile O-(methylcarbamoyl) oxime). Treatments in 1964 did not result in statistically significant seed-yield increases.
