“…In peppers, SHOREY (1963) related the speed of effect of systemic insecticide granules to the water solubility of the toxicants when applied in a furrow next to the plant row for the control of aphid. Furrow treatments in onions have been used satisfactorily against onion-fly in Canada (PERRON and LAFRANCE 1962), but topical applications were quicker in controlling thrips, in seven days, while the effect of side-dressing lasted longer, for up to 31 days, in agreement with conclusions above (HALE and SHOREY 1965). In small grains, LILLY et al (1958) found toxic residues for 47 days but not as long as 68 days after the application of phorate and fertilizer, broadcast and disced into the soil, but SKOOG (1959) considered there was little hazard from residues after applying phorate and disulfoton granules at seed depth with winter wheat seed to prevent grasshopper damage, although early pasturing of livestock on such wheat might be dangerous.…”

“…The water solubility of imidacloprid (Marathon II) is 610 ppm (0.61 g/L at 208C) (Jeschke and Nauen 2008), which is much lower than thiamethoxam (Flagship), dinotefuran (Safari ), and acephate (Acephate). Consequently, imidacloprid takes longer to translocate through the vascular system (i.e., xylem and phloem) and spread throughout plant tissues (Hale andShorey 1965, Tomlin 1994), especially in woody plant tissue (Byrne and Toscano 2006). Due to the woodiness of the Itea plants, a lethal concentration of active ingredient may have taken longer to reach and accumulate in plant leaves where redheaded flea beetle adults feed (Cowles 2010), which likely accounted for the differences in redheaded flea beetle adult mortality between the two laboratory experiments.…”

“…Insecticides with higher water solubilities tend to be more mobile within the plant. Therefore, the low solubility of imidacloprid may impede movement throughout plant tissues (Hale andShorey 1965, Tomlin 1994), particularly in woody plants as woody plant stems may inhibit the concentration of active ingredient that reaches and accumulates within plant leaves although this may vary depending on plant type, developmental stage, and the particular systemic insecticide (Cowles 2010). Both yellow sage and poinsettia develop woody tissue (Liberty Hyde Bailey Hortorium 1976), particularly later in the production cycle, which may delay the movement of imidacloprid throughout the plant.…”
