Control of Several Cotton Pests with Systemic Insecticides12

Abstract
In field experiments American Cyanamid CL-47470 (cyclic propylene (diethoxy-phosphinyl) dithioimidocarbonate), Cl-47031 (cyclic ethylene (diethoxy-phosphinyl) dithiomidocarbonate), and Union Carbide UC-21149 (2-methyl-2-(methylthio) propionaldehyde O-(methylcarbamoyl) oxime) granules applied in the furrow at planting controlled thrips (FrankLiniella sp.), cotton aphid, Aphis gossypii Glover, and serpentine leafminer, Liriomyza brassicae (Riley), for 4-6 weeks after planting. UC-21149 controlled the cotton fleahopper, Psallus seriatus (Reuter), for about 8 weeks after planting, CL 47031 applied as a granule sidedress treatment and as a lanolin-paste stem treatment gave fair cotton fleahopper control. As a sidedress treatment material it gave season-long control of the desert spider mite, Tetranychus desertorum Banks, and the stem treatment gave control for about 2 months.
